[stone]

Unless you're running a bunch of accounts this will be probably hard to tell, but does anyone know if PageRank (or just links from authoritative sites) are a factor in your bid rate on adwords?

For example, let's say you were bidding on "pet widgets", and it just so happens that all the popular niche authoritative websites talk non stop about your great pet widgets.

And then, of course, your poor competitor who comes out with a competing website but with a low quality product that nobody wants to talk about.
