Canonical tag?

Hi

What is Canonical tag?

[tehminamlk]

According to google's definition:

A Canonical tag is a piece of Code used by search engine spiders/crawlers to tell search engines what URL is the original version of your webpage.

Canonicalization is the process of picking the best url when there are several choices, and it usually refers to home pages. For example, most people would consider these the same urls:

The canonical tag was designed as a page level element in which you edit the “head” of the HTML document and edit the parameters.

A canonical link element is an HTML element that helps webmasters prevent duplicate content issues by specifying the "canonical", or "preferred", version of a web page[1][2][3] as part of search engine optimization. It is described in RFC 6596, which went live in April 2012.

Duplicate content issues occur when the same content is accessible from multiple URLs.[4] For example, http://www.example.com/page.html would be considered by search engines to be an entirely different page to http://www.example.com/page.html?parameter=1, even though both URLs return the same content. Another example is essentially the same (tabular) content, but sorted differently.

Very nice topic really i like this post. And canonical relationship should prove to be a very useful tool for developers for optimizing their sites.

Google, Yahoo and Live have not only embraced it, but also published their support and thorough explanations of how their engines will handle page indexing with implementations of it.

Thanks for..
