The 3 Major search engines Google. NSN and Yahoo have come together to support a new meta tag.



It is very rare that three Big Boss join up on the same thing. It must be something good, right?

The new meta tag deals with the canonicalization issue deals with multiple url paths that reference the same content.



What is a canonical issues ?





For those of you who don't know about canonical issues ;it is effectively a tag to deal with multiple pages with the same content

but with different tracking codes. The new tag also helps to reduce duplicate content problems.



An example of this would be:



http://www.domain.com/anand5.aspx?id=45

http://www.domain.com/anand5.aspx?id=45&this=true





Here is how the meta tag looks it should be placed in the head and will contain one URL all link values would be awarded to the URL stated.







This simply works just like your other meta or link tags for CSS / link tags,it means that you need to add the respectively to open and close the tag, the dynamically generated url parameters and the page itself are all pointing back to the original, which means your pages are no longer fighting amongst themselves as duplicates.



The Canonical URL tag attributes is similar in so many ways to a 301 redirect from an SEO perspective.



In true sense, you're telling the search engines that multiple pages should be considered as one (which a 301 does), without actually redirecting visitors to the new URL



From a Experienced SEO view that perspective duplicate content can seriously hurt your website page rankings my by including the canonical tag you can reduce the amount of duplicate content.





Ensure that all duplicate URL's or pages are under one folder then you can inform search engines using the canonical tag that the contents in the folder is meant to be duplicated and the URL you state in the tag will receive all the SEO link power that's currently mushroomed across the duplicate URL's and will help your several duplicate content penalty issues at large.



This new SEO canonical tag will helps to avoid all duplicate content issues and can be a great help for all of those using ID sessions, use sorting options of their products which cause presenting the same

content on different URL addresses. It's a great leap towards cleaning the search engine indexes from copies or duplicates of the same content.
