I bet I'll be banned from adsense!

I don't think you can have adsense and bidvertiser ads on the same site

 

They wont ban you unless your CTR randomly shot up, if it sustains at 20% then it wont seem suspicious, just great placement.

 

it's actually the same page... But ur still right! Thanks for reminding me!

 

This isn't really true, in some cases it's only slightly skewed towards that country.

There are plenty of regional sites out there which must get similar traffic patterns, because they advertise locally offline. If your ctr and impressions have changed dramatically, you might do well to email Google in advance to explain any anomalies. It makes sense that you would get a higher ctr for very well targetted traffic.

 

I think you no need to worry if the number of page impressions are coming from same region.

 

some sites are only destined for some regions/countrys, I'm sure google understands this. Let us know what happens anyway

 

Why not? As far as I know, bidvertiser is not contextual, and only contextual ad publishing programs are not allowed with Adsense.

 

That's what I thought aswell but I remember hearing you can't use bidvertiser+adsense somewhere else...

 

It is a bit risky to get a CTR of over 10 .

 

Not a problem at all. I run some sites in China. And all of my visitors are from China, most of them using IE. Seldom of them even use Google, they use Baidu.com. But my adsnese just works well.
