IBA ads don't show on Search because they're not as targeted as search...
When someone is on a site about recipes and they keep seeing ads about camping equipment, the idea is that the person interested in recipes is also interested in camping. Now let's imagine that the person on the recipe site got there via Google. Weren't they interested in camping equipment not more than two minutes ago when they were on Google searching for recipes?
What changed? It begs the question: Why is it good to show those on advertiser sites but not so good to show them on Google?
