Whenever I get hyper-repetitive ads (usually GM, Dodge, or financial products - seriously, is that all of the ad inventory in the network on some days?), it usually has the opposite effect; I just assume those companies' products and processes are as inefficient and wasteful as their advertising.

I will say that I'm thankful that Squarespace, Audible, and Skillshare support independent video and podcast creators. I click their referral links sometimes to check out new features etc, but would only ever sign up if I needed that particular service. Still, I think that form of repetition helps their mindshare in a positive way.

I did buy the Glif directly from an ad on Daring Fireball, albeit months later, and in combination with brand awareness from their free time-lapse / speed ramping app.
