A few weeks back, I received a Tweet from Matt Cutts that referenced a presentation on duplicate content (see slide show below). The slide show was presented by Greg Grothaus at SES San Jose.
What I found valuable was the content on slide 13, which touched on the use of the canonical URL tag to combat duplicate content issues that are associated with session id’s. Now, this is hardly news for those who follow SEO trends. However, up to this point, I have been somewhat skeptical of this new method and how effective it might be.
This presentation gives me confidence that this method is worthy of use and one that I should employ it when working with clients that have similar problems. Any thoughts?
