For Adwords ads, there are now no more "page 1, page 2 ads", there is just a long list of ads all on page 1, as many as 40 odd on some searches...
I wonder what this will do to distribute clicks away from those ranked higher (its obviously great news for anyone previously on page 2)
I doubt this is not related to the algo change a few weeks ago, and wondered what everyones thoughts were
