I strongly agree with Chrispcritters that showing followup ads can backfire if it's overdone. Remarketing is like pepper on your pasta ... you need to keep a light hand about it or you'll ruin the recipe.
That same question has been out there long before IBA existed. How many times does Google show the same ad to a visitor before changing the ad to something else?
Depending on where you go for reference, there are advertising books that claim sometimes a person needs to see a message 6 or 7 or whatever number of times before responding. I wonder if Google follows this theory and tries to limit the number of times an ad displays to an individual?
It's not just IBA that's causing the repeat messages to be shown to a visitor. A site about widgets might display a green widgets ad to a visitor each time he/she visits that site and even if a frequent visitor.
Is there a magic number of impressions that should cause Google to decide, "OK, that's enough, he's not interested, let's show him something else"?
