How to add Webmaster Tools to your site
Google Webmaster is a one-stop shop for webmaster resources that will help with your crawling and indexing questions, introduce you to offerings that can enhance and increase traffic to your site, and connect you with your visitors.
Sign-up for a free account
Sign up for Google Webmaster - http://www.google.com/webmasters/ - to get a free account. If you already have a Google Account you can sign in with that.
Sign-in and add a new website profile
Once you are signed in click the 'Add a site' link to add an url of a site you'd like to manage. Enter the entire url of your site, for example 'http://www.yourdomain.com/' and click 'Continue' and the Site verification page opens.
The next step involves verifying ownership of your site. Choose the 'Meta tag' verification method and copy the meta tag generated, which looks something like this:
With the meta code from Google in your clipboard go to your site's Config screen and select the Tracking and code option. Paste the tracking code into the 'Header code' field, and click Save. This step happens back at Tank.
Back at Google Webmaster you can now click 'Verify' in order to verify that you own the site you submitted. After you have successfully verified your site you'll end up at the Webmaster Dashboard for your newly added site.
Submit your sitemap (and feeds too)
In most cases there will be an status message indicating that your site has not yet been indexed, which means the first step would be to submit your sitemap and feeds to Webmaster for indexing.
Submit a sitemap
Simply add 'sitemap.xml' to end of the url and and click 'Submit Sitemap'
Submit RSS feeds
Simply add 'news/feeds/rss/' to end of the url and and click 'Submit Sitemap'. Remember to replace 'news' with whatever you called your post section.
Processing sitemaps may take some time. Check again later to see if pages from your sites are included in Google's index.
Once Google has indexed your site check back at Google Webmaster to find out how Google views your site, top search queries, crawl errors, links to your site, keywords and much much more.
To determine whether your site is currently included in Google's index, do a site: search for your site's URL. For example, a search for [ site:withtank.com ] returns the following results: http://www.google.com/search?q=site%3Awithtank.com .
