To understand the classification of the site in search engine results you must be aware of how Internet search engines work. And remember that the most important thing crawler (crawler) collected from each Web site content. Once you get a search query, the search engine searches its catalog (index) and finds all pages containing the keywords from this ruling. Sort engine, rated according to its key importance in these pages and send a list of results by the consumer. What classification algorithm using a search engine works and how business is secret. However, the major search engines follow some general rules.
