If you care about how your website is performing, then you should be aware that Google has set up Google Webmaster Central. It’s a one-stop shop for comprehensive info about how Google crawls and indexes websites. Google Sitemaps is part of this and has been renamed Google Webmaster Tools. It always was a jewel of a service and it keeps getting better all the time. Since for a technical website, possibly more than two thirds of its traffic may come from Google, this is an important place to visit often.
There is also the Webmaster Central Blog, which provides official news on crawling and indexing sites for the Google index. If you’re a serious webmaster, you undoubtedly check RSS newsfeeds and this is perhaps one of the most important blogs to subscribe to.
