This is kind of the nature of the beast with being an affiliate. You are being compensated for providing them traffic which converts at a substantially lower cost that their predicted lifetime revenue from the customers. If those lines cross, expect to be shown the door as soon as they're made aware of that fact. It is not economical to work with people to optimize their sites to hopefully be sending quality traffic again, since that is hard, non-obvious, might be against the interests or intentions of the site owner, and consumes resources which would be better spent optimizing the customer's own sites.<p>For example, a slight change in your keyword mix coming from Google -- not even a bad thing -- can make your traffic quality as measured downstream go from Great! to Abysmal! very quickly. Pretend that instead of me being both an SEO and a software developer the SEO was the affiliate of the software developer in my business.<p><a href="http://www.bingocardcreator.com/stats/conversion-rates" rel="nofollow">http://www.bingocardcreator.com/stats/conversion-rates</a><p>I was "sending" great, great traffic with SEO, until recently. The people who joined the free trial were disposed to convert. If I had been earning 25 cents a trial, both the SEO and the software developer would be pretty happy... until October.<p>What happened in October? Halloween happened. And I did fairly well SEOing for Halloween, and generated a metric truckload of new trial signups and sales... <i>but</i> the traffic is much lower quality than someone coming in for elementary education activities. My consolidated conversion rate took a nosedive, because the conversion rate for people coming from my Halloween sites is below 1%.<p>If I were paying the Halloween-loving SEO 25 cent CPAs at the moment, I'd be bleeding money and probably have to cut him, since I don't have sufficient insight into <i>his</i> business to realize this is a temporary condition and will rectify itself in another few days (right before it happens again at Thanksgiving... and Christmas... and Valentine's Day...).
