Understanding SEO(Search Engine Optimisation) [by Google Engineer MATT CUTTS].flv – YouTube.flv


hi my honour is Matt Cutts I’m an designer in the quality group at Google and I’d like to talk today about what happens when you do a network pursuing the first thing to understand is that when you do a Google search you aren’t actually scouring the web you’re searching Google’s index of the web or at least as much of it as we can find we do this with software programs called spiders spiders start by delivering a few web pages then they follow the links on those pages and retrieve the sheets they point to and follow all the links on those pages and retrieve the sheets they link to and so on until we’ve indexed a pretty big chunk of the web many millions of sheets stored across thousands of machines now guess I want to know how fast a cheetah can run I type in my pursuing say cheetah rolling accelerate and touched return our software examinations our index to find every page that includes those search terms in this case there are hundreds of thousands of possible upshots has Google decide which few reports I actually want by asking questions more than 200 of them like how many times does this page contain your keywords do the words is indicated in the deed in the URL directly contiguous does the sheet include synonyms for those working messages is this page from a quality website or is it low quality even spammy what is this pages sheet rank that’s a formula devised by our founders Larry Page and Sergey Brin that rates a web pages importance by looking at how many outside ties-in point to it and how important those links are finally we compound all those factors together to produce each pages overall rating and send you back your search results about half a second after you submit your search at Google we make our commitment to delivering useful and impartial search results very seriously we don’t ever admit payment to add a site to our index revise it more frequently or improve its ranking let’s take a look at my search results each introduction includes a title a URL and a snippet of verse to help me decide whether this page is what I’m looking for I also determine links to same sheets Google’s most recent collected copy of that page and related rummages that I might want to try next and sometimes along the right and at the top I’ll construe ads we take our promote business very seriously as well both our commitment to deliver the best possible audience for advertisers and to strive to only show ads that you really want to see we’re very careful to distinguish your ads from regular search results and we won’t establish you any ads at all if we can’t find any that we repute will help you find the information you’re looking for which in this case the Cheetahs top flowing rapidity is more than 60 miles an hour thanks for watching I hope this constitute Google a little bit more understandable
