Update your Sitemap

Updating a SitemapPrint Google recommends initially submitting your Sitemap using Google Webmaster Tools. This will ensure that your Sitemap details are readily viewable on the first tab of the Sitemaps page in Webmaster Tools. In addition to Webmaster Tools, you can also submit (and resubmit) your Sitemap using the following methods :

Sending a HTTP request to Google Including your Sitemap location in your robots.txt file

Resubmitting a Sitemap using Webmaster Tools On the Webmaster Tools Home page, click the site you want.

Under Site configuration, click Sitemaps. Select the Sitemap you want to resubmit, and then click Resubmit.

Resubmitting a Sitemap by sending Google an HTTP request.

If you do this, you don't need to resubmit it using Webmaster Tools. The Submitted column will continue to show the last time you manually clicked the link, but the Last Downloaded column will be updated to show the last time our system has fetched your Sitemap.

To resubmit your Sitemap using an HTTP request :

Issue your request to the following URL:

www.google.com/webmasters/tools/ping?sitemap=sitemap_urlFor example, if your Sitemap is located at http://www.example.com/sitemap.gz, your URL will become:

www.google.com/webmasters/tools/ping?sitemap=http://www.example.com/sitemap.gzURL encode everything after the /ping?sitemap=:

www.google.com/webmasters/tools/ping?sitemap=http%3A%2F%2Fwww.yoursite.com%2Fsitemap.gzIssue the HTTP request using wget, curl, or another mechanism of your choosing.

A successful request will return an HTTP 200 response code; if you receive a different response, you should resubmit your request. The HTTP 200 response code only indicates that Google has received your Sitemap, not that the Sitemap itself or the URLs contained in it were valid. To obtain status information about your Sitemap, resubmit it using Webmaster Tools account. We recommend that you resubmit a Sitemap no more than once per hour. An easy way to do this is to use the Sitemap Generator to set up an automated job to generate and submit Sitemaps on a regular basis.

Note :

If you are providing a Sitemap index file, you only need to issue a single HTTP request that includes the location of the Sitemap index file; you don't need to issue individual requests for each Sitemap listed in the index.

Including your Sitemap location in your robots.txt file

To tell search engines about the location of your Sitemap, include the following line in your robots.txt file (updating with your own path and filename) :

sitemap : http://www.example.com/sitemap.xml
