If one had to take a wild guess at the biggest advancement to take place in the world of SEO post Sitemap, it has to be the introduction of the Canonical URL’s. With some of the biggest search engine giants, such as, Google, Yahoo and Live announcing their support to the canonical URL, this is slowly becoming one of the most sought after tag.
Canonical URL helps the webmasters to eliminate the need to duplicate the entire content in the index as it is already supported and listed by the search engine. It is important to understand how canonical URL operates. This tag is included in the header part of the HTML. In many ways, it is quite identical to the nofollow tag. Just as nofollow, it makes use of a new rel parameter.
The above command would tell the search engines that the concerned page should be treated as a copy of the link given in the command, thus eliminating the need to copy the entire content in the new page.HTML Code:<link rel="canonical" href="http://www.jv-extensions.com/blogs" />
This tag can be used in a variety of applications, such as
- When search engines are confused amid the ranking of various versions
- When the search engines aren’t guided properly whether to direct the entire content in one search result or separate the link metrics in several pages.
- When search engines are not aware which versions of a website to include/exclude.
