...what about these awful ad?
Do you KNOW they are awful? Or do you just THINK they are awful?
If you know they are awful then ban them.
If you just think the ads look awful but don't really know as a matter of FACT, then do a test to see if removing them improves your earnings. If your earnings go down, then you know the ads are not awful.
If earnings go up, then you've confirmed that the ads are awful.
Nobody can tell you how an ad will perform on your site. They can only tell you how ads performed on their own sites, which could differ from your experience.
Also, be sure to note if someone is sharing their opinion of such ads or their experience. Experience counts for more.
This is something you have to find out with testing on your own site.
Let us know how your tests go.
Thanks for bringing up this topic as I've always wondered about these kinds of ads.
Best,
;)
