AdQuant: Google’s Top 100 Search Advertisers

I just reviewed AdQuant’s reporting of Google’s top 100 search advertisers in April 2009 (by daily PPC ad spend):

* AOL represented nearly 5% of April PPC ad spend for Google (up significantly from March)
* Credit / credit repair / refi represented 43 of the top 100 at just under 20% of the PPC top 100 ad spend
* E-commerce represented 22 PPC advertisers and 24% of the top 100 daily PPC spend
* 19 travel-related PPC advertisers accounted for 21% of the top 100
* 18 insurance-related advertisers (14%)
* The remaining 20% were broadly search (Edmunds and GM.com were the only 2 automotive sites listed)

It is interesting that 43 credit / refi advertisers are still spending just under $1 million per day.
