What type of ads are these?

I keep seeing sites with the One ad format, just curious how people are getting these?

I get those all the time (well, sometimes) and i HATE them because they are usually very poorly targeted to my content!
If they were half-way targeted to my site i guess they would be ok.. I bet they pay well too because the advertiser probably has to pay 3x as much as a 'regular' ad..

 

those are normal ads. i get them sometimes on one of my blogs, it's like the same code it just displays it different for whatever reason. sometimes it displays the regular 4 ads and sometimes the 1 huge one, it's kind of weird.

 

Well, the same thing happens to me also. Whether it is a large rectangle ad or skyscraper I see many times this type of ad. Whats the soluting for that ?

 

These ads might be site targeted .. try to block that site using competitor filter and check

yeah, my site too, some time gets this kind of ads. i think maybe this kind of ads show, to site with unpopular keyword.
