Algorithms for search engines

It should be noted that all these "laws" are extremely dynamic change. For sufficiently small changes in the algorithm of search engines, like sorting priorities changed. However, the modern SEO-copywriting, and the result of his work (actually SEO-text) Has a high buffer strength. This means that a small adjustment in the external factors and cosmetics (and, hence, requiring virtually no financial cost) changes in the SEO-text content can neutralize the negative (if it proves negative) and to maximize the positive impact of changes in search algorithms. The presence of such buffer properties suggests that investments in SEO-copywriting sufficiently long. Incidentally, modern trends of development of search algorithms are uniquely optimized to enhance the role of the semantic core of the text content in the search progress. When administrators learn how to search engine "to separate the wheat from chaff" is not based on someone else's opinion (and this is exactly the essence of the mechanisms account external factors), And with the direct determination of the quality and level of utility "presented on the pages of the thematic textual material, then all optimizatorskie tweaks will almost useless. And the winners will be those who bet on a full-fledged content optimization, content on the site is not garbage imitations of articles, and real, live, interesting texts users.

History of search engines

Initially, when the Internet was just beginning to grow, the amount of information available was relatively small, and users were few. The main users of the Internet in the early stages of its development were employees of various research laboratories and universities. While the main purpose of the network was to exchange information between research institutions, its ability to be used to implement various research projects. In the initial stages of development, the relatively small size of the network, the area of information retrieval was much less relevant than now.

As an initial way of organizing access to information resources via the Internet used catalogs sites, Which is usually used thematic grouping of links. Pioneer in this area has Yahoo, which appeared in April 1994. Over time, the number of sites contained in the catalog increased, and the developers have created a special search engine directories. But such a system, of course, can not be called a search because the search was strictly limited to only those resources that were present at this site.

Brochures have been widely disseminated and used widely, but the internet is a dynamically developing, and together they developed and search methods. At the present time is difficult to find a system based on directories. It's very simple to explain, because even today the directory which will contain a huge number of resources that can provide access to only a small part contained in the information network. The biggest to date directory on the network, called Open Directory Project or DMOZIt includes information about the 5 million resources, which is quite a bit. After all, for comparison, the base of a world-famous search engine like Google has about 8 billion documents.

The first full-fledged search engine on the expanse of the Internet has appeared only in 1994, it was WebCrawler.

And a year later, in 1995, launching a search engine AltaVista and Lycos. The search engine AltaVista for many years held the forefront of the search for information online.

In 1997, Larry Page and Sergey Brin, students at Stanford University, have begun to implement a research project, which was developed by search engine Google, which today is the worldwide leader in the field of search.

Also in 1997, the month of September 23 the number of officially announced the creation of the Russian search engine Yandex, which is still market leader in search services in Russian segment of the network.

Today, there are only 3 search engines international level, it is MSN Search, Yahoo and Google, which have their own databases and search algorithms. Most everyone else on search engines as a basis using the results of the three above. For example, search engines: Mail.ru based on the search engine Yandex and search.aol.com based on the search engine Google, and search engines such as Lycos, AltaVista and AllTheWeb use database search engine Yahoo.

The leading search engine runet today is Yandex, the second place is Rambler, followed by Google, Mail.ru, Aport and KM.ru.

Key words and inquiries

Search engines are based on the words requested by users to determine the results, which will be processed in accordance with their algorithms, ordered and issued to the user. However, search engines do not just recognize and retrieve exact matches of the requested words, they use knowledge of semantics (the science of language) for the construction of intellectual relevance. An example would be the case when the request loan providers search engine displays results that do not contain this phrase, and word lenders.

Search engines collect data on frequency of use of words and their joint distribution in the network. If the relevant words and phrases are often found together on pages or sites, search engines can construct intelligent theories about their relationship.

This extensive knowledge of the language and its usage gives the search engines to determine which pages are thematically linked, what is the subject page or site, as a reference structure of the network is divided into thematic community and much more.

The development of artificial intelligence search engines in the field of language means that the results of queries users are becoming more intelligent and evolving. Huge investments in the area of processes of natural languages will help achieve greater understanding of the meaning and intent in the user's query. In the long term as a result of this work, users can expect the increased relevance of the SERPs, as well as more accurate assumptions about the expectations of the search engines users.

Link Building 101

In the past few months I have had an enormous desire to publish this material, however, the company that I work actively discourage this. Lately, I see an increasing number of posts dedicated to the strategy of building and developing a network of back links, some are simply delusional, that's why I decided to violate the prohibition of their employer and to publish this article.

I'm not suggesting all the possible ways of constructing a network of links that you can only imagine / create / come up, but this story certainly help you to find a sufficient number of new interesting ideas. This article I wrote several months ago to teach our young team-level specialists of certain techniques to increase the mass of reference web resources.

Building a network of links

Capacity referential mass - is the only sure way to achieve high positions in the ranking site in search engines. It is vitally important to make a sustained and continuous action to build referential mass, which will eventually reduce the cost of advertising and the site will take an advantageous position in the SERP.

Google has created one of the most successful algorithms for information retrieval, which is based on the direct orders of spiders make transitions to all detected links. Yahoo, MSN, Ask and other searchers expand their information base in the same way, moving from one to another vebdokumenta links. Links play a crucial role in defining the search engines value the resource and have a major impact on the ranking of a website.

The best that can be made for the site - it is natural to construct a system of unilateral backlinks. Usually, these links appear at forums and blogs, as these resources are the first to show interest in the valuable information on the network.

In the general theory - the more websites will refer to any Web document, the higher the position it will occupy in the search engines. Google introduced their assessment of the relevance of document called Page Rank, in other words, the page rank. Estimated it at ten-point scale. The more valuable is the site for the search engine, the higher the Page Rank (attendance also affects the figure).

Number of backlinks can be checked in many ways. The browser Firefox has an additional module that allows visitors with just one click of a mouse displaying a list of resources linking to a particular site. There are many embedded public toolbars that allow you to receive the same information. Also there is a special Web services, which offer a lot of tools to search for backlinks.

Google, in essence, is a unique search engine, as it shows a specific percentage of links that are only noticeable weight, whereas the other search engines give out information about the total number of backlinks. Also, this search engine recognizes "illegal" ways to expand the reference mass to influence the ranking of the site.
