It only takes half a second for Google to return a search based on keywords you type in, but there’s a whole lot more happening behind the scenes to give you the results you need. Google on Monday launched a video that explains the science behind how the massive search engine actually works.
Matt Cutts, software engineer head of Google’s webspam team, details in a YouTube video how the search engine giant thoroughly scours the web on a daily basis to provide the most up-to-date results to users.
“There are three things you need to do to be the best search engine in the world. First, you need to crawl the web comprehensively and deeply, then you want to rank or serve those pages and return the most relevant ones first,” Cutts said.
Although Google crawls the web on a daily basis, that wasn’t always the case.
Well this is very reliable details that how the google looks the whole web i realized some of the factors but not temporarily know about it so its a excellent one for all of us and me as well
