When the sitemap file of your website changes, you can resubmit it to Google to let them know about the updates of your pages. Resubmit your Sitemap in one of two ways:
To resubmit your Sitemap using an HTTP request:
Issue your request to the following URL:
www.google.com/webmasters/tools/ping?sitemap=sitemap_url
For 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.gz
URL encode everything after the /ping?sitemap=:
www.google.com/webmasters/tools/ping?sitemap=http%3A%2F%2Fwww.yoursite.com%2Fsitemap.gz
You can issue 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 your webmaster tools account. We recommend that you resubmit a Sitemap no more than once per hour. An easy way to do this is 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 one HTTP request that includes the location of the Sitemap index file; you do not need to issue individual requests for each Sitemap listed in the index.
- Sign into Google Sitemaps with your Google Account and from the "Sitemaps" tab, select the checkbox beside it and click the "Resubmit Selected" button. The Submitted date will update to reflect this latest submission.
- Send Google an HTTP request. If you do this, you don't need to use the "Resubmit" link in your Google Sitemaps Account. 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 the Google system has fetched your Sitemap.
