You may give it a few days to see if the reduction was caused by your server issues. Also I would add a 728x90 under your header and above your login. You may also want to swap sides with your login and current ad block. If all else fails try YPN or Chitika. Chitika clicks - while not as plentiful as adsense on my site - generally pay pretty good per click. I average about $.30 per on the site on the site where I use them.
thanks filtalr, I can't wait to try out YPN when it comes out of BETA. I'm sure the UK will be the next country allowed to participate
Thank you sundaybrew your have been very helpful and everyone else too! I've changed the homepage to see if I can get more clicks and changed the text as well
I'd really love to know if the other publisher programs are this bad. I totally sympathize and am looking to leave Adsense for good, I feel as though I'm just spinning my wheels here..
I agree with sundaybrew, You need to try other revenue streams like CPA network ads which pay you cost per action amounts (sometimes just for a name and email address you can make $1.00 or more)
I guess, your keywords are not high paying keywords. I mean, your keywords may be those for which people bid very less at adwords. what is your niche and what keywords you are targeting. I mean around what keywords your text/content revolves?
