We’ve been tracking the growth of
Sitemaps
on the web. It’s been just 2 years since Google, Yahoo and Microsoft co-announced the
Sitemaps rule in robots.txt,
and it is already supported in many millions of websites including educational and
government
websites! At the WWW’09 conference in Madrid, Uri Schonfeld presented his summer internship work
studying Sitemaps from a coverage and freshness perspective. If you’re interested in how some
popular websites are using Sitemaps, and how Sitemaps complement “classic” webcrawling, take a
look:
Sitemaps: Above and Beyond the Crawl of Duty
At Google, we care deeply about getting increased coverage and freshness of the content we index.
We are excited about open standards that help webmasters open up their content automatically to
search engines, so users can find relevant content for their searches.
Как мы это применяем
We archive Search Central announcements because client questions often trace back to a change that was announced years ago. Reading the original is faster than reconstructing it from second-hand summaries.
