I run both.

I'm not crazy about how they make the site look but cant argue with the revenue it generates month-over-month. It's needed now that Adsense earnings have been in decline for a few years.

Yes I use them, they are not implemented on very many pages so all and all I don't get that many impressions from them. But, the click through rate is higher on these than on standard ads. They only trigger on mobile, so its an additional and effective means monetizing mobile traffic.

Here is is a link to thread on the topic started a while ago. [webmasterworld.com...]

Thank you

Can anyone share success? e.g. have you tested on say so million impressions to see conversion?
