The main purpose of ads isn't to sell you a specific product immediately, their real purpose is to expose you to their brand to make the brand more familiar (and therefore more trustworthy) to you.
For example, recently, I needed a new insurance. So of course I went to the websites of the 5 insurance companies that I knew from advertising and compared their offers. Then I went to a comparison portal, which again I knew from the ads. The best offer was from a brand I didn't know so I went with the second one which was from a well known brand. I trusted the second offer more, simply because the brand felt more familiar to me.
Here's another story: there is this big online clothing store. I always hated their ads, they were really annoying, and at that time I didn't understand why anyone would buy clothes online. So guess where I went, 5 years later, after a disappointing offline shopping tour, in desparate need for new clothes?
