The only ads I ever click on are when I search something like “brother dcp-l2550w toner” and the first result is an ad for Staples where I was going to buy the thing anyway. Even if I saw an ad for that exact toner and said “ah, that reminds me I need more toner,” I’d still not click that ad but rather go search as described because I do not click ads.

There have been times I’ve been so annoyed by a company’s ads that instead of buying their product I go with their direct competitor out of pure spite (if I needed something like the item in question, ykwim).
