Edit: I misread the post to be 28% CTR, you can ignore my comment.
There's absolutely no fucking way CTR for those is 28%.
I do not believe that.
Posts don't even have a CTR that high, that would mean the average user goes no further than 4 ads before clicking one.
Now I wish I bought some stock so I could get in on a shareholder lawsuit about them cooking the books on this shit.
Edit: for context, it's 0.9% on FB, 1.9% on Google.
What's more likely, someone at reddit fucked up an analysis, or these ads are 14x better than Google or 31x better than FB?
