huge drop in ctr
 

Hello guys, i have experienced huge drop in my ctr and first i would need to explain my problem.
me and my mate are running 2 same designed websites with familiar content (yt videos). at start 7 months ago we had about the same ctr (2.5-3%) but now in the past month my ctr dropped 300% and its about 0.7% now. I have to mention that we have same traffic and everything else is the same (except myb 30% different yt video posts) . what might could be a reason?
p.s. could it be about different hosting ?

Not to burst the bubble, but past experiences states that youtube vids content sites have a high possibility of Google ban.

Yup.
You should have soem quality content as well as youtube vids. Maybe descriptions etc? Also, the reasons you have worse CTR might be because of more views or new audience?

Yep, I agree the best way is to have good quality original content.

i appreciate your consider, but there is no answer about what might could be a reason, is it possible that google did some discrimination off me, or that there is some bug, i have received one message from adsense : "Did you know you're only running AdSense ads across 25% of your pages on uk.to? Get closer to achieving your site's revenue potential by adding new AdSense ads across the remaining pages". But i dont understand this, i can see my adds on every post. I added one in header and 2 in single post above and below the content.
your opinion?
