I recently added a link to about 500-1000 classified ads I have running. Purely as a landing page. I had no intention of ranking this site at all. Quite by accident found that the domain is on page two for the keyword the in the anchor text. I can assure you the links from these sites are absolutely nofollow. Apprently I have enough of them that it matters! This kills a couple myths for me. 1. A link Doesnt have to be on relevant pages. 2. No follow links DO count.
