Google,Microsoft to clean up the web

As all we know that,whenever a person searches something on the internet it sees a lot of pages for its corresponding search.The msot frustrating thing that any user found about these pages,that many of them contain the same content that means there exists a lot of duplicate content on the internet.But now Google,Microsoft and Yahoo decided to take measures on this,according to them support a new web standard that will allow millions of publishers to remove duplicate pages from their websites. As a result of that, search engines would be able to make their search results more comprehensive.According to Google,this problem arises due to the e-commerce companies that having multiple URLs that all point to the same page.Now to cope up with this problem Google came up with a simple way for web publishers to indicate when a URL is a duplicate, and if so, which is the principal, or "canonical," URL that search engines should be indexing.Now after this all search engines start modifying their search engine in this way.
