Earlier quoted context omitted.
Ad companies make money based on clicks, not views. It's in their interest to make them interesting enough to click on.
I don't think that's true, because who is clicking on these ads for things they already own?
Think about billboards, TV, radio, and magazines. Can't click on any of them, yet hundreds of billions of dollars are spent on them every year because repeating the brand, logo, visual, or message works. There's a reason McDonald's and Coca-Cola advertise heavily. It works.
