Crawling: Does Google

index your site?
Serving: Does the site
have good and useful
content that is relevant to
the user's search?
Crawling is the process by which Googlebot
discovers new and updated pages to be added to the
Google use a huge set of computers to fetch (or
"crawl") billions of pages on the web. The program
that does the fetching is called Googlebot. Googlebot
uses an algorithmic process: computer programs
determine which sites to crawl, how often, and how
many pages to fetch from each site.
Googlebot processes each of the pages it
crawls in order to compile a massive index of all
the words it sees and their location on each
page. In addition, we process information
included in key content tags and attributes, such
as Title tags and ALT attributes. Googlebot can
process many, but not all, content types.
When a user enters a query, our
machines search the index for
matching pages and return the results
we believe are the most relevant to the
user. Relevancy is determined by over
200 factors, one of which is the Page
Rank for a given page.
