[Sachin89765]

You can use the URL Parameters tool to indicate the purpose of the parameters you use on your site to Google. For example, if you are the owner of a global shopping site, you might tell Google that you use the country parameter to distinguish between pages dedicated to consumers in different countries. Then you can set preferences for Google might crawl the URLs that contain those parameters. The preferences that you set can encourage Google to crawl the preferred version of your URL or simply prevent Google from crawling duplicate content on your site.
