Yes i have, but it seems that it's changes in the past few days with the local listings and google places.
Are you mad? This is a question? Just type this site..Google.com..and count post there you will find 10 + 1 to 10 sponsored links.
There are 10 links in each page. So you need to get in top ten for a keyword to get good visitors for your keyword.
in Google SERP........result varies........y i am saying this........... because when u search for specific product or specific location it will show local listing with some sponsors linking .................
I've also noticed the changes for local listing. But generally, top10 on the first page is default setting.
