After having read this thread, the answer seems to be a tentative "Yes", but I am curious if I am doing this wrong, or causing myself problems, for a specific situation.
We have a thread on the forums that has over 50,000 views for that thread alone. No doubt many people have linked to it across the web, and it ranks very well with Google. But we are dealing with a major problem in that the main portion of our site (home page and core content) which are the most important, aren't ranking in Google at all.
A big part of this is because that part of the site hasn't been updated in years, whereas the forum is updated daily. By users.
We've begun putting out quality content in our News Center lately, and hoping to start boosting its presence in Google. We have an article on the exact same topic that the forum thread covers. I was thinking of putting a canonical on that thread, pointing to the article, and hopefully pointing some very powerful link juice, popularity, and traffic into our news center articles. People can comment there as well if they like.
Are there any potential downsides to doing this? My hope is that the forum thread loses rankings and the article takes on its rankings.
Thank you.
