I agree, but there are two differences IMO: * Ads have tracking and security implications. For clicking though to a site, that is far less the case (an individual site can't correlate my visits across multiple sites, whereas an ad network can). * Going to the site at least gives an opportunity to present alternative monetisation strategies (direct payment or donations, or selling additional content/services - depending on the nature of the site). If you are just getting the information from the Google page, that disappears.
