Yes, I do. Although Google will deny any Organic Listing and AdWords linkage, there is what I call “size is matter” formula signal. It is one of the secret 200 signals making the organic ranking formula. Don’t get me wrong – It does not mean Google gives it a lot of weight, but definitely some sort of points are credited toward a company that spending big amount of $ on Google AdWords. Google can surely say “if these guys can spend $100,000 per month, sure they are big company. I like them”.
