Major Search Engines Come Together Agianst Canonical URL

Major Search Engines (Google, Yahoo and Microsoft) have come together to fight against the problem of duplicate contents. The top three search engines are implementing support for the new HTML tag - “link” .

The link tag will tell search engine crawlers which canonical URL form it will use when retrieving search results. The link tag put all the Canonical URL at the forefront of the website content which will be used for accessing the page, regardless of the session id, link parameter of the URL form.

To implement Canonical URL form on website, site owners just need to add the following link tag at head section of the site’s HTML code.

link rel="”canonical”" href="””"
