Increasingly, the sites are modernizing and trying to keep up on top in search results. However, you need to invest in technology to achieve better positioning. Due to the considerable increase of material available on the web, it is essential to determine its existence so as to remain competitive. A site that is ranking in the search will surely be benefited.
As a definition, we have:
Also known as Robot, Bot or Spider. These are programs used by search engines to explore the Internet and automatically download web content available on web sites. They capture the text of the pages and the links found, and thus enable search engine users to find new pages. Methodically, it exposes content and deems irrelevant content in the source code of sites, and stores the rest in the database. It is a software developed to perform a scan on the internet in a systematic manner through information perceived as relevant to their function. One of the bases of the Search Engines, they are responsible for the indexing of websites and storing them in the database of search engines.
The process that executes a web crawler is called Web crawling or spidering. Many sites, in particular search engines, use crawlers to maintain an updated database. Web crawlers are mainly used to create a copy of all the visited pages for post-processing by a search engine that will index the downloaded pages to provide faster searches. Crawlers can also be used for automated maintenance tasks on a website, such as checking links or validating HTML code. The crawlers can also be used to obtain specific types of information from Web pages, such as mining addresses emails (most commonly for spam).
The search engine crawlers generally seek information about permissions on the content. There are two ways to block a decent crawler from indexing a particular page (and the links contained therein). The first, and most common, is through the robots.txt file. The other way is through the meta robots tag with value “noindex” or “nofollow”, used to not to index (the page itself) and not below (the links in the page), respectively. There is also a third possibility, much less exploited, which is using the rel = “nofollow” for links, indicating that the link in particular should not be followed.
The Robots Perform In Three Basic Actions:
As we can see, behind any search performed on the internet, there are a number of mechanisms that work together to provide a satisfactory result to the user. The process seems somewhat complex, however, nothing noticeable to us mere information seekers.
According to the Alexa site, Google is the most visited site in the world. Not coincidentally, the site created by two college friends not only changed the way we look for pages, but also the way we create our sites so that most SEO companies virtually ignores the existence of other seekers, making the sites of their clients appear on a good position or on the first page of Google. But there was a time when the Internet giant simply did not exist. In this article, we will understand how searchers were this season and how Google managed to impose, beyond the controversies that surround the site on the privacy of its users.
The first seekers
As you may know, the Internet has emerged in the mid-1970s. At that time, it was restricted to military and academic institutions. Its users were using services such as Telnet, FTP and e-mail. In the 1980s, popularized to the BBS (Bulletin board system), computer systems that allowed its users to read news, exchange messages, and download and upload files.
It was only in the early 1990s, Tim Berners-Lee created the World Wide Web, which would allow the exchange of information through the hypertext transfer protocol, HTTP. It is important to know, therefore, that the Internet is much greater than the web, but the web is part of the Internet that is more accessible around the world.
With the advent of internet shopping, began to appear on various websites, pages created by companies and ordinary users in the world wide web. Since the number of sites already surpassed the tens of thousands, it was necessary to have some sort of “phone book” that lets users quickly find the information they sought. There were, then, the search sites that at first were basically three types: directories, “crawlers” and meta search engines.
The directories are websites that specialize in collecting, storing and categorizing links to other sites. They run on three elements: title, keywords and description. All this information can be found in <head> section of a web page. On these sites, you type the key words you want to search and it returns the page title, its description and address. Yahoo!, one of the first search engines that appeared on the Internet. Currently, DMOZ is one of the few remaining directories, edited by humans.
Yahoo! Homepage In Mid-1997
The crawlers functioned similarly to Google. Instead of storing just the title, keywords and description, they also kept the content of the pages, making the search more accurate. The Altavista was one of the major crawlers and search engines in the higher end of the 90s.
Already meta search engines such as HotSPot, differed from the first two because they are “leeches” in the best sense of the word. Unlike directories and crawlers, they had a database itself, but returned to the user results from other search sites.
Thus we see that, before Google, the market for web search sites was dominated by basically three types of sites: directories, crawlers and meta search engines. All of them, however, had serious flaws.
If both directories crawlers stored as links to other pages, the key question is: who will appear first when you do a search? The classification should be fair for all, therefore, could not be done alphabetically or by last registered site. Thus, most search sites were guided by the keywords contained in the page to sort your results – and that is where the issue was complicated.
Say you are looking for a Data Center in Bangalore, you would type something like “Data Center Bangalore” in the search box and the search engine would return all pages that have those words. The problem is that, this system is very easy to be deceived in both directories as crawlers.
In directories, which are searched by just the keywords and description of the site, not the content itself. Soon, it was common to make a “spam” of keywords to get more clicks. So the chance was that, you’ll find a site that is related data center and fall on a page that is without the content or, at worst, maliciously or with adult content.
Although the crawlers have partly solved the problem of directories to search the content of the page itself and not just in your keywords. Many webmasters put certain keywords in hidden text or in excess, ie, the same color as the page background, making their sites move ahead in position, making the user running the risk of finding only garbage in their research.
So, with the two main methods, needed a new way to sort the search results.
In 1998, the Ph.D. students Larry Page and Sergey Brim launched the project on which they were already working two years ago: the BackRub that later would be called Google, a reference to gugol, which corresponds to the number 1 followed by 100 zeros.
The uncommitted college project was to have an exponential growth in its early years soon, leaving behind all market leaders of search engine hitherto. This achievement is mainly due to two factors: its simple design and powerful algorithm.
As you can see by analyzing the images of the text, the initial pages of search sites in the 90′s were packed with links leading to or categories of sites, or user services, such as email and chat, or even advertisements. Google, however, decided to bet on simplicity, which would become its trademark, putting forward the user to only your main tool: the search form. The clean visual made users fall in love with Google search engine which made it popular, but it was eventually being copied by competitors, and was a major factor for the popularity of the site.
While most search engines ordered search results based on the keywords of each page, which could give rise to fraud, the folks at Google decided to follow another path, ordering pages for its importance. To this end, they developed a series of algorithms called PageRank, which assigns a value of 1 to 10 for each site, the higher the value, the more important is the site. A link from site A to site B represents a vote from site A to B. The higher the PageRank of a page, the vote has more weight and thus, based on links a page receives, determine the order of search results.
Soon, Google revolutionized the Web not just for its simple design, but mostly for its innovative way to rank pages, which silently dictated new rules to build pages. If before, due to the nature of search engines, there was great concern about the internal organization and layout of the pages, the need to appear in the top positions of Google opened a new market: SEO, which was responsible for making the internet a better place.
Privacy: The Achilles heel of the Giant Mountain View
But there are not all flowers in the success story of the search giant. From its earliest days, the company was facing problems in relation to treatment provided to the data of their users – and the list was to grow every day.
Soon it started to become popular around the world, in the early 2000s, there was a great controversy over the so-called “immortal cookie” Google. Cookies are pieces of information that websites write to your hard drive to remember your preferences. They allow, for example, you log into a page, close the browser and when opened it again, the page will be showing your profile, without the need to re-authenticate. The problem is that the cookie of Google was originally scheduled to expire in 2038, 40 years after the founding of the company! Added to the fact that the cookie assigns a unique ID to each computer and that the company records all the searches you make, it could mean that they could keep track of all your life based on your searches (currently the cookie of Google is scheduled to expire in 2014, refer to your browser.)
Undoubtedly, Google has managed to impose and change the web for the better. But the question that remains is: are we ready to live without it?
Google has been making some major changes to its algorithm recently, primarily to penalise sites that contain low-quality content and “content farm” websites. The latest string of updates is to further improve the search result relevancy; and of course, the first Panda update that was implemented by Google had resulted in affecting 11.8% of all U.S. searches. And it had resulted in major websites being impacted, while other websites were benefited from the changes. Some major websites that were impacted includes About,com, Demand Media (that owns websites such as eHow) and Yahoo! Associated Content. However, it is important to stress that websites that continue to publish high-quality content will not be affected by the ongoing algorithm labeled “Panda”.
It is important that you rectify any areas of your website or blog that may be affected by the Panda algorithm. The only in which the penalty assigned to your website by the Panda algorithm is by removing poor-quality content. You can’t really label “good-quality content” – because to most people, we know what good quality content is and we also know what bad quality content is. But by using analytical tools to understand what pages are doing well and what pages aren’t, it can paint a picture as to what Google’s algorithms are determining on your website as poor-quality content and what pages are high-quality content. But either way, it is important to replace poor-quality content with good-quality content otherwise your rankings will not improve while there is poor quality content on your website or blog.
A “content farm” is a website which sole purpose is to write content often systematically to try and get as much traffic from search engines for relevant keywords as possible – which often leads to lower quality content because the content may be written by someone who may not have adequate experience in what they are writing about and because they may not be paid much, the motivation to write as much content as possible on a daily basis may be a greater emphasis than writing good-quality content with each article or piece of content they write on.
Google sees content farms as a major problem, and many of these algorithmic updates are to target and tackle the problem of content farms. Demand Media, which owns eHow and other websites, are to some people considered to own content farm websites because of the amount of content that is published on these websites and because some articles may be poor compared to the same kind of content from other sources. It appears to me that sites like eHow write articles generically compared to a blog that has editors that are experienced in the field they are writing about. For example, many of the articles I’ve seen on sites like eHow are generic and do not help assist in resolving a specific issue and sometimes simply give generalised directions on a specific subject or problem.
Google refers “webspam” (to differentiate from e-mail spam) as web pages that have too many keywords embedded to try and fool search engines into improving their web page’s search engine optimisation or link schemes. For pages that have too many keywords, this is referred to as “keyword stuffing”. It’s important to take note about the use of reciprocal link exchanges. While this can benefit your sites SEO, too much link exchanging can trigger Google’s algorithm for excessive link exchanging which can negatively impact your websites rankings.
Google has illustrated in its blog post on rewarding high-quality websites that websites and blogs that have articles that have out of context link placements shall also be penalised under what we will call the “webspam” algorithm update. The article in question appears to be about fitness but it has completely unrelated backlinks in the blog post itself to a website offering pay day loans. Google’s algorithms are smart enough to detect this kind of behaviour, and rightfully so, will penalise websites and blogs that do this – that is, have “unusual linking patterns”.
Over-optimisation is something that appears to be more sensitively recognised by Google’s algorithms. If you read this blog post by an editor on Seomoz.org, one of the editor’s website was penalised for having a backlink on one of his other blogs – the keyword being “Web Strategist Philadelphia”. Once he had changed the keyword to his site URL, his rankings were improved over the following few days afterwards. You may wonder why that would be considered over-optimisation, but it may well be over-optimisation because you’re getting backlinks on the keywords you are directly targeting. It is recommended to have only natural backlinks and if you want to target certain keywords, you do so with careful consideration to make your anchor text natural.
Google has made a blog post explaining what high-quality content may be. Some are pretty obvious examples, such as “spelling, stylistic and factual errors” which is to say grammar and punctuation errors with your content and factual errors with relation to your content and what you’re writing about. In fact, there is another one listed in the article – for websites that have excessive amount of advertisements. I had thought of this before as to whether Google takes this into account; because, for most users, a web page with too many advertisements is both annoying and distracting.
So bottom line is, good SEO can be:
Storing files in the cloud is already a common practice among web users. Google, for example, allows you to save documents, pictures and other data from anywhere with an internet connection. So, start editing a Word document at home and bring it to work has become more simple: just send to a server and access it without having to walk in the company with pen drives from one side to the other.
In January, when the Megaupload was closed by U.S. authorities, many users felt hurt. Not because of the fact that copyrighted files were taken from the network, but because the service was also used to store information of legal users, much like the Google. Of a sudden, millions of documents and photos were lost when access to Megaupload was interrupted, and thus a cloud storage option was lost.
This event raised a question: how safe are the files that are stored in the cloud? Is there any guarantee that they will not be lost or if the cloud service is taken offline, as users can do to recover the holding?
For more sites and servers that can be closed, the cloud is hardly impaired. The cloud computing, as the internet, there is a system dependent on a single connection. The scenario that every cloud will disappear is practically impossible.
A single server can fail, but, according to the experts, the great cloud computing companies have plans for possible disasters. Large corporations have backup plans and disaster recovery plans in case of floods, earthquakes and other natural disasters. Thus, if more than one server is damaged, the files are stored on some other server as well, thus preventing users from losing their data.
Another concern is regarding the safety of the cloud. Not everyone feels confident when leaving important files with personal information stored in a place that they do not know exactly where it is, despite knowing how to access them easily. The biggest risk is not confidential data, but the possibility of losing data. If you rely on a single provider, you need evidence that they are keeping your data offline.
My recommendation is to make a second copy of your files elsewhere. It’s a good idea to save the data on your own computer, for example, to avoid losing important data.
Since Google opened up the business to create pages on Google+ two weeks ago, they have started to provide basic tools for companies to enter this network. While industry analysts believe that Google+ Pages can find a profitable niche in the world of social networks among business users, for now there is a perception that Facebook could overtake Google+ when it comes to providing businesses with a place to reach the hearts of customers.
For now, there is a list of features that Google+ pages does not count, including the ability for companies to offer promotions or coupons, as well as the POSSIBILITY of hosting contests or sweepstakes. Companies in Google+ pages also cannot sell products. Many of these features are available on Facebook and now the users want them on Google+ Pages.
In July, shortly after Google has allowed the creation of pages in Google+, Facebook launched Facebook for Business which is basically a guide to assist businesses to use Facebook features targeted for business, social plug-ins and ads. Facebook has made it clear that they wanted to lure companies and took advantage of the delay in the launch of Google+ Pages. Now, months later, analysts say that it is clear that Google+ is yet to be mature.
Right now, Facebook has a more complete offer, but all this could change quickly. Google and Facebook are not exclusive choices. Many companies have a blog and a Twitter and a Facebook page. Now, they will add a page in Google+.
Many companies are entered into the world of social networking and see the audience of Google with good eyes. If Google add processes to improve the solution, it will be really useful and valuable for companies.
But first, need to address the problems that users have noticed recently. There are some real limitations on pages that make it harder for companies to use the solution the way they want. This condition can significantly reduce the adoption. For example, only one person can manage the account, so either the individual will be responsible for the company’s site or you have to share the login and password with multiple people. This is not recommended.
In considering these points, Facebook has an advantage when it comes to social network aligned with the business. But Google will need to work on changing that. On the other hand, no tool is “everything to everybody. In recent weeks, Google said that it was exactly the idea which is going forward .
The CEO of Google, Larry Page said that he wants to “transform” the company, integrating its various services with Google+. Google has taken a huge step in this direction by integrating the Google+ with Google Apps, a suite of cloud-based enterprise applications.
As many of you know that the world of SEO has changed dramatically with the Google Panda update, the algorithm of Google is always looking for new techniques to avoid any possible positioning of website based on duplicate content, poor quality content, pages with a poor design or that its only function is to grow backlinks.
It is for this reason that, in positioning our website we must take this new Google function into account when assessing the site. One of the key measures to achieve this is to get an increase in time spent by visitors to our sites displaying our content. Until now it was very common to find well-positioned sites with poor content.
With the entry of Google Panda, it is difficult because the new algorithm introduces new measures to detect the content without interest to the visitor. To achieve this, we have to rely heavily on the introduction and reference point for social networks ( Facebook, Twitter and Google + ) to serve as a social measure. Google already appreciated this for a while, but now it has become much more important to have presence in social networks, and currently if you have no presence in these networks and not receiving visits and “like”, you will lose a lot of appreciation from Google.
Another measure is to consider the design of a more functional website. Before that Google could “understand” while the page was sufficient proof of this and there are many websites with a little care and simple design which are aesthetic but accessible from your code to Google, which had allowed good evaluation by Google. Indeed we must also be careful about the placement of advertisements on our site, as it is important that this is an orderly design and not an obstacle to visitors.
Some of the steps we can take is to avoid to publish content without any interest , you can choose from resources such as embedded videos to force the display of the same from the website. This will make web visitor stay longer for video on the website. Of course, opting for quality written content is equally valid, because what we have to clear is not so outstanding as before by direct assessment by Google but the social value of our website, directly or indirectly will most affect us at valuation.
As mentioned, a key point is the presence on social networks and social tools in general to make use of Google Panda. One is the “+1” on Google. We can add the buttons of Google +, Facebook and Twitter on our website so that our visitors can share and evaluate our content. Of course we must also allow the inclusion of comments to the extent possible and in general any function that allows users to interact and be part of the site.
Anyway… Google Panda will advance and expand its capacity, but it seems clear trend toward social value.
With the growth of the value of clouds for some IT solutions providers are beginning to take an interest in what exactly it meant. In the end, many of you have long offered clients to use host-applications, which, in essence, cloud services are under another name.
So you already know what are the benefits that are provided by cloud computing services to your customers: a small initial capital costs, or complete absence, pay only the actual services received, scalability and flexibility. For you, the main advantages of cloud services are a constant revenue stream, deep penetration in the business of clients and flexibility to tailor services to customer needs.
So if you have some time provide Hosted Exchange services with or related to backup and restore data, you are completely forgivable to ignore the talk about clouds as the next hype in the IT industry. Or unforgivable?
Enough to have in its arsenal, one or two services such as SaaS, although they could well help you prepare for the era of cloud services. Looking to the future, customers will increasingly move their infrastructure into the cloud. And if all that you can offer, is the e-mail host system, you face the loss of customers.
Since virtualization, private clouds and services based on public clouds every day are becoming more popular. IT has a long history of adaptations and innovations, and cloud is a important chapter in this story. If you skip this chapter, it can have fatal consequences for your business.
Large corporations such as Verizon and Google, end users are bombarded with advertisements on its cloud products. As this onslaught of more and more customers will be prepared to cloud computing and would like to have more services.
Fortunately for solution providers, you have plenty of options to create a full set of cloud services. Let’s say you have to offer Hosted services through Exchange. What can you supplement them? It makes sense to explore other products Hosted on Microsoft, such as server, database and maintenance of desktop systems, to create a cloud menu.
Of course, you are not limited to products of Microsoft, Cisco and Dell. You and all the solutions provider should also not be overly suspicious of large corporations. In particular, although Microsoft has achieved record sales through the channel, the manufacturer has caused some confusion among its partners on their role in providing cloud services, such as Azure and BPOS. However, Microsoft’s strategy in connection with the clouds deserves a separate article.
Solutions providers should also pay attention to host the infrastructure and services such as “platform as a service” (PaaS), as well as to private cloud using virtualization technology and reminding the public clouds, which allow you to take advantage of the cloud environment inside the network perimeter.
Many manufacturers also offer in addition to its virtual cloud product technical support. This means that you can give it to function manufacturer partners and focus on growing your business.
So when it comes to clouds, then, yes, there is no shortage of publicity. But this does not mean that solutions providers cannot simply ignore it and do its routine. Clouds are a source of change, and therefore require that providers of solutions once again adjusted to the ongoing large-scale shifts in the industry.
In early 2011, Google reported a change in its leading position in the list of major internet companies. There are many opinions about the causes of the fall ranked by Google in this list, but everyone agrees that there is a tendency to accelerate changes in the sphere of information technologies. Each company is eventually undergoing some administrative changes and has its own economic cycle. But much more important now, as these internal cycles coincide with the rapid development of data centers industry in general, and cloud hosting technologies in particular.
During the first five years of the last decade Google has been queen of the ball. Its name became the basis of the verb (“Google” – to search the web). It has changed the nature of the search, use and attitudes to information. They did not invent the search engine, it was simply meant to improve it, and the world has changed beyond recognition. It is predicted that it will replace the Internet itself! And then came the “Social Internet” and more people began to use the services of Facebook and Twitter, and Google search engine and RSS feeds overshadowed. Information business has changed, as well as many other industries. Nobody noticed this, but in fact the second five-year plan last decade was very different from its first five years. And although Google still means something in the field of Internet search, social networks, no doubt, came to the first position. We cannot say definitely whether it is strategic or administrative problems for the search company, because in reality, it does not matter. What really matters is what people are saying that Google is not so popular.
What implications does all this might have for other companies that are not related to Google or not are the pillars of the Internet? If you produce cars, drugs, or widgets? Maybe you sell bricks or mortar. What if your company is not related to the field of information technology business? Regardless of the scope of your business, we can assume that this shift from 10 to 5 years, probably will affect your business too.
Today, almost every company and every industry is built on information. The sign may be written in “Fashion House“, but in fact almost any business is related information.
Information on financial and capital markets risk management, information affecting the adoption of certain decisions, information that is necessary for cooperation, information to track users and interact with them through various means of communication. And most of this information is at your data center or moved to a “cloud hosting” structure with a common access from anywhere in the world. You cannot assume your business to be information-oriented, as in the case of Google, but in reality it just is. And companies that are most actively engaged in the information business, according to data center as a key strategic asset. It is used as a weapon in the competition.
This means changing attitudes towards the IT infrastructure, data centers and the potential use of cloud hosting technology.
In other words, what seems easy now, may no longer be so after 5 years.
The concept of cloud computing is Quite fashionable today and it is treated differently. It is the image of computing in which IT resources with a high degree of scalability are provided to users in the form of services through the Internet. A pool of managed computing infrastructure with a high degree of scalability is the provision of paid services on the placement and implementation of client applications.
And as per Wikipedia “cloud computing treats simple Technology Data Processing, in which software is made available to the user as an Internet service”.
In fact, “cloud” is a metaphor for a remote data center computing, to which access is given on the basis of payment for pay-as-you-go (pay per actual use of the service computation). Thus, the software is actually provided to the user as a service. Cloud computing user does not need to worry about any infrastructure, nor on the actual software, “cloud” successfully hides all hardware and software components.
And Intel shares the concepts of architecture and cloud-services. The first category includes the components of a dynamically scalable capture of resources, based on virtualization technology or software environment with horizontal scaling. The second – as a rule, paid services that users receive via the Internet. “Cloud” architecture can be constructed within the local network. Unlike traditionally distributed or service models, cloud computing is based on a dynamic architecture and the user pays only for the functionality, which really enjoys. The scope of cloud computing may be different – this, for example, online mailboxes, social networks, specialized search engines, online financial services cloud computing and other applications of Web 2.O.
Despite the fact that cloud computing is the concept that is still relatively young, already made projections of its future development. In the first (2007-2011), there will be many pioneers, and their new development will ce launched in the market rapidly. Further, roughly from 2011 to 2013, will begin a consolidation phase – some vendors leave the market, while others merge with more successful competitors. And in 2013 comes the “golden age” cloud computing.
Among the pioneers of the market of cloud applications and services, including quite large manufacturers, such as Google, IBM, Microsoft, SAP, Oracle, etc. Microsoft last fall announced a platform for Windows Azure, based on Windows 2008 Server.
Along with additional services, including Windows Live, a portal solution to SharePoint, this OS will be a comprehensive solution for creating and deploying applications for online computing. A similar system along with cloud web hosting services is introduced by ESDS - its Virtual Data Center Operating System platform create and manage the data center.
A number of solutions (both hardware and software) in the cloud computing is based on the architecture of Nehalem. The Dynamic Power Node Manager, and Data Center Management Interface, allows not only to optimize power servers, but also reduce the cost of managing data centers.
Communication products supporting virtualization and cloud computing is delivered by Cisco. Cisco Nexus family of switches replenished Nexus 7000 Series, 5000 and 2000 models. Model Switch Cisco Nexus 7018 chassis is equipped with 18 slots and supports up to 512 ports Ethernet. Nexus 5010 also supports Ethernet, and Fibre Channel, and the model of Nexus 2000 is to expand the bandwidth of a server farm.
Many IT experts say that in the near future, cloud computing will be included in the top list of technological trends, and certainly could become a very profitable service for those companies that will seriously deal with them and constantly develop them for better benefits.
