How can I automatically generate SEO keywords based on dynamic page contents?

Question

I have a webforms (framework 3.5) site with a TON of dynamic content. Depending on the url, one or many content items will be sent to the client. I need a way to generate meta keywords for SEO based on the contents of the page (or part of the page, if possible).

I've done a little research and am not really turning up anything that addresses my problem directly. I have, on the other hand, found some interesting stuff that might get me there with considerable work. One idea I have is to intercept the response buffer at Application_BeginRequest (global.asax), parse out some meaningful keywords, and inject them back into the response buffer. However, this seems like a pretty expensive process and I don't even know if it's possible. I also feel like there could be a way to do this with an HttpModule.

I'm interested in what the community has to say about this. Is there already an existing and accepted way to do this that I'm just missing.

Answer 1

Thomas pointed out in the comments to my original question that the major SE's ignore all meta keywords. I needed some proof to this so I did a little more research. I found the following blog entry at Google's "Webmaster Central Blog" which confirms what Thomas said: http://googlewebmastercentral.blogspot.com/2009/09/google-does-not-use-keywords-meta-tag.html

I'd give Thomas the credit for the correct answer, but I can't since his was just a comment.

Yah I would agree.. we've been successfully ranking our sites with SEO for 5 years, and meta keyword spamming doesnt do you any good. Everything is about relevant incoming links, so i'd say focus on that ;)
