I know to give the answers to this is a bit hard. But I find again and again people are not happy to see one company ads again and again over time. Some are utterly hating it and asking companies to stop showing your ads.
I asked one of the complainers, would it be fine if he sees ads only 2-3 times in a day, and his answer was not more then 1 time in the day, which means I guess is he even doesn't want to see the ads.
My personal experience is also the same, I don't like to see ads over time again and again.
How you guys are managing Remarketing strategy and making sure your ads don't annoy your previous website visitors.
