Need help increasing CTR

For some reason the CTR on my proxy has gone way down over the last month or so. Does anyone have any tips for optimizing it?

I was thinking of using a script to randomly change the background color. Do you think that would have any impact?

 

hey your ads are not relevant to the content

 

They're not? What kind of ads would you expect to appear on a proxy site?

 

it shoes relevant here...

but its too spammy in my eyes...

i would like to have it cleaner and lesser ads...but if this works for you, then its fine...

colors are good imo...

 

but I would change your colors, black background is not good and cant match your google ad colors with black.

 

Once the proxy site is down, it mean either your proxy already been blocked or user already adapt with the theme and ignore your ads. So change the theme regularly.

 

Nice placements. Everything are above the fold which are good.

 

proxies in general arent getting very good ctr lately. even with the best optimization my site still dropped from about 6% to around .5% on a good day. proxy business is dead.
