A few questions from our Google Group

May 24, 2006

In this post, we thought we'd answer a couple of the questions we've been seeing in the Google Group lately.

There are several reasons we ask you to add the Sitemap file. Here are a couple of them:

  • If you aren't yet indexed, submitting a Sitemap file lets us know about your site--you can proactively tell us about it rather than wait for us to find it.
  • When you add your Sitemap file to your Google Sitemaps account, we can let you know if the file has any errors, and then you can resubmit the file once you've fixed the errors.

My site is indexed using both the www and non-www versions of the domain. How can I fix this?

This can happen when both versions of the domain (for instance, http://www.example.com/ and http://example.com/) point to the same physical location, and links to your site use both versions of the URL. To tell us which version you want the content indexed under, we recommend you do a 301 redirect from one version to the other. If your site runs on an Apache server, you can do this using an .htaccess file. You can also use a script. Do a Google search for [301 redirect] for more information on how to set this up for your site. Note that once you implement the 301 redirect, it may take some time for Googlebot to recrawl the pages, follow the redirects, and adjust the index.

If your pages are listed under both versions of the domain, don't use our URL removal tool to remove one version of the pages. Since the pages are at the same physical location for both versions of the domain, using the URL removal tool will remove both versions from the index.

We also suggest you link to other pages of your site using absolute, rather than relative, links with the version of the domain you want to be indexed under. For instance, from your home page, rather than link to products.html, link to http://www.example.com/products.html . And whenever possible, make sure that other sites are linking to you using the version of the domain name that you prefer.
