I use amazon.com as my display url, I try to bid high so my ad can show, but it cost me alot more than I get from Amazon if I get the sale. Do u have suggest Lanx? How to do effective ppc especially with Amazon. I know more profitable if I sell digital product like Click Bank's product, but my country isn't in the list and I don't know alot about making website, SEO, so I do ppc with direct link! Is anyone here have good suggest for me, I really need to get some money for my wife's medical cost.
