My site has 2+ years long, domain is 5+ years old. I only use google adsense and Amazon.I don't know why, my traffic is keeping good, but I have less and less income. So I'm planning to try some other ads. I'm not a Japanese, I can't use other ad servers in Japan for they require Japan Bank account. If you know some good ad server for my site, may you tell me? Thanks! If you want to buy ad place on my site, please feel free to contact me for detail. Alexa:<40K, Google Analytics Latest 30 days: visitors:384,210, pageviews: 1,679,218, Japan visitors: 93.66%. I plan to sell two ad space: Top banner (728x90, now is google adsense) 600$USD/m Right Box (120x150, now is Amazon) 300$USD/m
