Search Engine Marketing (SEM) & Search Engine Optimization (SEO)

Many websites that use CMS (Content Management System) make the same content available via different URLs. If Google knows that these pages contain the same content, Google may index only one version of the content for their search results. Sometimes, the version chosen by Google for indexing might not be the one you want indexed. Ignoring certain parameters in your website’s URLs can reduce duplicate content in Google’s index, and make your site more crawlable. With Google Webmaster Tools, you can specify up to 15 parameters you would like Google to ignore.

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.Click the Parameter handling tab.
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.)

Please take note that Google will treat these requests as suggestions rather than directives.
