Search engine algorithms ?
Once a search engine has a large store of pages, they allow users to enter keywords in order to locate them. In order to return the most relevant pages possible, search engine engineers create algorithms to work out which pages to show. An algorithm is essentially a series of calculations or formulas designed to determine the most relevant pages. Now that there are many billions of web pages available, search engine algorithms have become extremely complex, with many hundreds of factors involved in selecting an appropriate page.
