Does the Canonical Tag Help Google with Dynamic URLs

[proxima]

The recent Canonical Tag is just Great as far as eradicating the duplicate content on the web is concerned!

But does this help in how google sees the dynamic urls ?

With a not so adequate knowledge about how google sees the Dynamic URLs as not so google friendly, I was looking for all the information that is available for changing the dynamic URLs to the Static ones.

I am not sure if this tag saves all the research that I was about to do starting from the .htaccess files to the MOD rewrites for the php applications. OR is this tag really a substitute for that , Anyone - Any comments on that would be much appreciated.

Thanks,
Arun

Welcome to the forums, proxima.

Yes, the canoncial tag should also help with dynamic url problems - as long as you can program the correct variation of the url to be inserted into the tag.

However, I would still suggest using the 301 redirect on your server whenever possible. It's a sure thing, and the canonical tag is too new to be 100% certain of how it will work in every case.

This just in - a new 20 minute video from Google's Matt Cutts all about the new canonical tag.

Looks to me like the Google advice from a few months ago to "use dynamic URLs" was preparing the way for the release of this tag.

"use dynamic URLs" + Canonical Tag + "use Tagged Facts in the Description" = formula for better classification of page ?
