Google search engine algorithms
Algorithmically Google search engine PS (search engines) are mathematical formulae, with which the PS give out the sites in the search results. Thanks to these algorithms, PS find sites by key phrases or words. They also help to find sites that best meet the needs of users and exclude those that do not meet the requirements, or use black optimization methods (black SEO). Search engines, using an algorithm, analyze the content of sites, identify the presence or absence of key phrases in the content and, depending on the relevance of the content to the user, decide whether to display the site in the search (and at what position) or not. For each of the search engines developed their own algorithms, but the principles of all algorithms are similar. For example, all search engines check the uniqueness of the content, but the algorithms responsible for this process may differ analysis tools.
Algorithms in the Google system began to appear after the introduction of the citation index, the essence of which is to rank sites and pages, depending on the number and quality of incoming links. Thanks to this very successful innovation Google search engine has become one of the most popular.
Initially, Google algorithms took into account only the internal attributes of pages. Then other factors began to be taken into account: geography and novelty of information. Since 2000, the Hilltop algorithm was used, which helped to calculate PageRank more accurately. A year later, the entire mechanism of the PS was rewritten, and Google began to allocate non-commercial and commercial pages. Also, a factor was introduced that adds more weight to links that lead from reputable sites.
The first challenge for Seo professionals has become the algorithm “FL”, which is excluded from the search page, perispomeni keywords and pages with repetitive keywords.
The next was the Oreon algorithm, which takes into account the quality of indexed sites and reflects the most relevant results.
Another innovation was the algorithm “Austin”, which was a system of filters and penalties.
In 2009, the “Caffeine” algorithm was introduced, which significantly improved the infrastructure of Google’s search engine. As a result, the search became much faster and more pages were indexed.
