SearchEngineWatch recently added a Florida Update section with tons of great information. A few weeks back Overture ads started to appear in the Yahoo directory. The problem is that the ads are frequently poorly targeted, and some of them get indexed by search engines.

A search for "Cleveland search engine optimization" shows a resulting listing page about Cleveland Zoos from the Yahoo directory with an ad for a Cleveland SEO firm.

For those who think that being in the AdSense program can boost your search results, this is a perfect example of why Google is using JavaScript to feed the sites (and thus prevent the ads from altering search results). Integration causes conspiracy theories and may well degrade results (as shown above.)
