99.99% of the time I don't even pay attention to them. Occasionally while cruising a site I may see an add for a company I am unaware of. For example I was on a firearm site the other day and saw an add for an online arms dealer I had never heard of. So I clicked it to see if they had good prices. And they did. Haven't bought anything from them yet but I might some day. I did bookmark their site for future reference. That is a rare case though, honestly its probably been a couple years since I clicked on an add on purpose. I do click them on accident sometimes though.... definitely more than I click them on purpose
