Now I have a register lead program running using google adward,I am satisfied with the result I got,that means veryday I can get 2 or 3 people register from my ad in 2-3000 impression,and keep my adward cost in low level,I am eager to get more earning from it. How can I expand my result ? If I add my click price,that may result in my losing in earning,because the commission for single registration is not high If I add keyword to my ad,I guess it doesn't work well,I have already add all keyword I can found which is relevant! How can I expand my result?
