I'm investing a lot in generating leads through Facebook campaigns.
How do I stop my ad being shown to people who already clicked on it and signed up?
Because I feel showing the ad to them would be unncessary and they might get annoyed, report the ad for irrelevance and hence increase the CPC for me.
I know something similar can be done through the custom audience settings where you can exclude people who saw the thank you page.
But the downside is that it will show the ad only to the people who visited the site, thereby resulting in lesser reach.
I need a mechanism to only exclude the people who've seent the thank you page.
Any help would be appreciated.
