The right way to canonicalise??

Hi guys,

I recently came across a site using the <base href="http://www.domain.com/"></base> on their domain http://www.domain.com/default.asp seemingly to combat canonicalisation issues - is this right??

I have never seen this used for this purpose, but reading further it seems it can be used.

I was wondering what everyone thought about using this method againsts using <link rel='canonical' etc and any other methods?

Many thanks,

Misch

    Hi Misch,

    The Base element allows you to specify the default URL or default target for all links on the page. I doesn't really resolve canonical issues except for relative URLs on outgoing links. While it can be an aid, it falls short of an actual solution.

    Where it might be useful is how it could include a dynamically generated base URL when used within a CMS that supports many different websites, and perhaps some special case scenarios.

    Now the element that really helps to resolve many canonical issues is the new "link" tag with the rel=canonical attribute, supported by all 3 of the major search engines.

    You should really think of canonical issues as a systemic problem that needs to be addressed at every level rather than a problem with a simple, singular solution.
