As John Prescott found out, it is often in the eye of the beholder.
Right now I have next the Pprune logo an ad for vitamin pills - I ordered from them a week ago. The other ad is for a BA-American Express credit card - I booked a flight last week.
The smaller ad to the right is for APL - no interest and the headline ad is for career progression, again no interest.
It looks as if the main banner ad is indeed cookie related, the headline and small ads are wide-area ads.
