Reasonable traffic but do not make money

Hi, I have a website with reasonable traffic:
15,000 - 20,000 page views daily.
I have Adsense running 3 months ago.
First month: Reasonable earning
Second month: Earning slash almost by half
Third Months: Less than 10 clicks daily
Reasons might be those surfers are sick of seeing the same old ad daily. Currently, its not enuogh to cover our hosting fees.

I would love to join some CPM related network, but most refused to sign me on because I lived in Asia. (My website surfers are 70% from USA).

Anyone knoews any CPM network or other reasonable ways to generate some revenue from the website?

Thanks in advance.

Sign up with affiliate programs that have products or services that relate to your website.

I had signed up with cj.com but when I apply for all the top 15 "EPC" affiliates, all got rejected. It might be because of the fact that I was in Asia. Although I was in Asia, most of my surfers are in US (70%) and the website is in English. For other affiliates that I try to join, I do not even have the option to join when they actually ask for my US address.

Right on. Focus on a target group.

This has been a problem for me too on some of CJ's affiliate programs, since I'm from Norway.
Most of my traffic does also come from USA.

A tip is to e-mail the affiliate programs that you want to apply to,
(most of the programs has an affiliate contact listed in the program info)
and tell them that most of your traffic is from US.
It worked for me.

Thanks. I had just emailed them and I hope that I can at least cover my hosting fees!

Have you tried using all the different sort of Adsense ads like the skyscraper, the standard sized ad, etc.

Also have you tried putting it in different locations on your site and also using different colors for the ads.

For the amount of impressions that you get, I should imagine that you should be getting alot more than just 10 clickthru's a day.

Refreshing your ads is important as well as closely monitoring your CTR (click through rate) and ROI (return on investment). Our affiliates that use Pay per click marketing are some of our most successful affiliates and earn about $400- $2000 monthly. I'm not sure what your monthly hosting fee is, but you may find our program a good fit for your audience. I agree with those that suggested contacting affiliate program managers. I always encourage affiliates to contact me whether they are a part of our program or not. Our sites are targeted to the US, but some of our overseas affiliates do quite well with their targeted ads. If you would like to discuss our program in detail, please feel free to contact me at any time.
