I don't really go to the Allow & Block ads section of my adsense account often. If ever really.
I do block domains here and there when I see them served on my site and feel they aren't a good fit.
I'm wondering, is it worth the time to go through all those ad previews and block stuff?
How often should this be done? I assume it helps boost earnings - but wondering if it's worth the time and trouble.
Thanks.
