Know How Google Search works
Every time you search, there are thousands, even millions, of webpages containing beneficial information. How Google works out which results to show starts long before you even write, and is influenced by a commitment to you to give the finest information.
Google’s business is search (along with ad serving), and it’s laser-focused on it. Google performs a variety of measures to guarantee that data is given to you quickly: It starts by creating a comprehensive index of the World Wide Web using MapReduce and PageRank. It does this on a regular basis, so the results are always current.
