Google search engine


Hi, today our topic is going to be about a famous search engine called Google search.
Google search is a Web search engine owned by Google, Inc., and it is the most used search engine on the Web. Google receives several hundred million queries each day through its various services. Google search was originally developed by Larry Page and Sergey Brin in 1997.
The domain google.com attracted at least 135 million U.S. visitors in May 2008.
Google's algorithm uses a patented system called PageRank to help rank web pages that match a given search string. The PageRank algorithm computes a recursive score for web pages, based on the weighted sum of the PageRanks of the pages linking to them. The PageRank derives from human-generated links, and is thought to correlate well with human concepts of importance. The exact percentage of the total of web pages that Google indexes is not known, as it is very hard to actually calculate. Previous keyword-based methods of ranking search results, used by many search engines that were once more popular than Google, would rank pages by how often the search terms occurred in the page, or how strongly associated the search terms were within each resulting page. In addition to PageRank, Google also uses other secret criteria for determining the ranking of pages on result lists, reported to be a number over 150.
Thus Google knows how to attract the users towards them and also got a big victory among all the other search engines.
All the best for Google.
