You search for “Canon cameras” and a search result ad shows you where to buy a Canon camera in your area.

I see - thanks for the explanation. I try to filter out those sorts of ads too, because I don't want my decisions to be biased by the money someone else spends, but they certainly are less annoying than the usual sort.

I wonder whether you would consider ads for fashion houses in a fashion magazine to be "solicited" or "unsolicited"?

Excellent example. Others might include grabbing a brochure for a car or visiting a product webpage (like an iPhone page).
