You can also have a website promoting multiple CPA and affiliate offers whereas with Google AdSense you are limited to 3 ads. There are better options than AdSense with some people testing Ezoic, media.net, and a few others – there are actually many alternatives to AdWords. There are different types of CPA offers from sites like maxbounty.com, peerfly.com and you can use offervault.com among others to find more offers. Some payout per 1 page submit, some pay per sale, and some pay per call. It depends on the offer. If you are working direct with a company and bypassing the middle man you can get higher payouts and even negotiate a hybrid model where they pay you for the lead as well as a commission on the back-end.
I have one affiliate website that I recently launched. SEO hasn't been done yet other than basic stuff. What I need is an expert to look at it and tell me whether I'm on track or need major changes. I don't know if you guys do that here or know of someone who does. (free or for a fee) The site is http://saveongolf.net . It's a site using datafeeds for golf equipment.
