People can really tune out most ads.
Banner ads, affiliate links, etc. draw semi-interested clicks. A lot of times, just curiosity seekers. But, someone actively searching for something, taking time to use an engine and keywords they think will bring up their desired results, are much more likey to have genuine interest in clicking on a SERP and taking action on the site.
There can be a banner and a text link, one right after the other, and the text link will consistently generate much higher quality traffic and much higher conversion rates for those that arrive via the text.
Lots of companies will spend many thousands of dollars on banner ads, in-data banners (banner that looks like text), and other placements, and get more (2x) traffic from seach engines w/o really embarking on much of an SEO campaign.
