Since the launch of Google Webmaster Tools its team has been working on updates and how to tutorials on using sitemaps. Based on the research highlighted in this sitemap crawl study (pdf), which showed how search engines find new and changed content faster with sitemaps, webmasters should take note.
Google and the other search engines that make up sitemaps.org, now support as many as 50,000 “child sitemaps” of sitemaps index files. In the past, they only supported 1,000. With this increased limit, webmasters can submit up to 2.5 billion URLs with one sitemap index.
Google’s Webmaster Tools , design update shows users all sitemap files that were submitted for a verified site. By the way, here’s a brief look at the update:
According to officials at Google’s Webmaster Blog, “This is particularly useful if you have multiple owners verified in Webmaster Tools or if you are submitting some Sitemap files via HTTP ping or through your robots.txt file,” notes John Müller, Webmaster Trends Analyst at Google Switzerland. In addition, the indexed URL count for sitemap files in Webmaster Tools is “more precise” according to Müller.
XSD schemas have been updated to allow sitemap extensions. This allows for the creation of better sitemaps through the verification of more features. Müller says that sitemap file processing is also much faster than before, meaning the time it takes to submit a sitemap file, process it and see initial data, is much shorter.
If you want your sites to rank higher on Google , take advantage by using sitemaps the way Google’s Webmaster Tools suggest.
