Almost no relevant ads

As an English site, these days there are almost none English-related ads to my adsense ads. I only collected a few non-English ads clicks from pages not so much related to English as a whole.

I have written to Google, but too eager to know what happens after all ? Google is doing some testing on its side ? And simply drive all PSA or charity ads to the site for testing purposes ?

In fact, my site used to be quite consistent in clicks and CTR but recently the drastic downturn makes me unease about what's wrong with that. Anyone out there experiencing the same thing ?

Or maybe Google is punishing me for some wrongdoings that I never made or I don't know I've already made ? I told Google that some areas can't see the ads display and give them the ip addresses.

Yes I have experinced very drastic falls (50% plus), if this continues .. all my dreams of quitting my job and become a full time web master are gone.

I reckon this all has to do with the Florida Google Crash the Over Optimization Penalty. People will not feed anymore the hand which slapped them ... and now .. adsense publishers are geeting the hit!

Believe me there is nothing out there which compare to adsense. I tried in excess of 100 affilate programs in 2 years and non work as much as adsense.

If yahoo bites away at googles market share, now is the chance and then they can offer something similar to adsense, there are various problems though. Yahoo has a lot of page views I suspect more than google and that means they have a lot of room for publishing. So in the end you cannot put all your eggs in one basket, the problem really is I only found one basket!

any thoughts ?

My only tip is hold on and stick out
