Parameter handling

Many sites make the same content available via different URLs. Say you have a clothing site and one of your top items is a green dress. The product page for the dress may be accessible through several different URLs, especially if you use session IDs or other parameters:

If Google knows that these pages contain the same content, we may index only one version for our search results. However, you can specify up to 15 parameters you'd like Google to ignore (Google treats these requests as suggestions rather than directives). Ignoring certain parameters can reduce duplicate content in Google's index, and make your site more crawlable. For example, if you specify that the parameter sessionid should be ignored, Google will consider to be the same as

This feature is case-sensitive, so be sure to enter your parameter exactly as it appears in your URL.

(For information on other ways of indicating your preferred page versions, see Canonicalization.)

To specify how you would like Google to handle parameters:

1. On the Webmaster Tools Dashboard, click the site you want.
2. Under Site Configuration, click Settings.
3. In the Parameter handling section, click Adjust parameter settings.
4. For each parameter, select the option you want. (If no parameters are listed, Google did not find any when crawling your site. You can still add parameters yourself.)
