I'm pretty sorry that I didn't read the items of your website carefully which lead to my understanding mistake.
I suppose that you've checked my website.It belongs to educational website which mainly provides information service for skimmers.And my web is just a suitable place for commercial ads with pictures or words.
After receiving your reply,I did some research on your web again,just found that some ads were suitable to be on my site.And I'm very glad to be used,ads like travel,health etc.
As you said,your way of counting on ads is mainly CPA,here,please forgive me for not being careful in reading your terms of your site which made me misunderstand.And CPC is one of those ways which I can accept.
I do apology again,and please accept my application.Thank you~
