ad to content ratio

[TeamTimmy]

What's a good ratio of ad to content on a website? That is, how much space should ads take up in relation to the amount of space your informative content takes up?

As long as your site has worthwhile, original content on it (i.e. it's not just made to put AdSense on it), there's not a golden "text-to-ads ratio" or a word limit for ranking. I worry that you're just looking at the trees and not seeing the forest. Optimizing your site for search isn't about counting the words on a page, it's about making sure that you have useful, usable content, and then making that content accessible to search engines.
