If you're having problems submitting a Sitemap, make sure that the URLs in your Sitemap include the URL of your site exactly as it appears in your Webmaster Tools account. For example, if you have added the site http://www.example.com to Webmaster Tools, don't list URLs in this format: http://example.com/home.html. Instead, use http://www.example.com/home.html.
The Sitemap Details page lists any errors Google found with your Sitemap, as well as warnings about potentially problematic issues. See details about the most common Sitemap errors.
View the Sitemap Details page:
- Sign into Webmaster Tools with your Google Account.
- On the Webmaster Tools home page, click the site you want.
- On the left-hand menu, click Optimization, and then click Sitemaps.
- In the Sitemaps list, click the Sitemap you want.
Once you've reviewed your Sitemap and made any changes, save it and then resubmit it. It can take some time for Google to process the resubmitted Sitemap, so the warning status may continue to display until then.
