Clickbait. A low-down dirty shame, that's what it is.
If you want to know why some of us are so opposed to programmatic digital ad placement, all you really have to do is click here.
Bob Hoffman of the Ad Contrarian (http://adcontrarian.blogspot.com/) calls it the "most eyeballs possible on the cheapest possible website." And it's a crime.
We've all clicked those sort of things now and again, but as a standard medium for advertising a reputable product or service? Please.
And yet, people do it all the time. And every one of those ads you see on one of these horrible sites counts as an ad placement. Somebody is paying for it.
Better? Place your own digital ads and don't let some heartless, non-thinking computer do it for you.
