I don't know if it's just an isolated situation, but I came to the conclusion that sales go down if your banner or advertisement graphic is flashier than the site itself... The Test: I drive traffic to my store from my main site, and I had an array of standard hyperlinks that led to pages within my store. Not pretty at all, just a bunch of grouped links.. It was converting about $100 a day in sales as an affiliate (not counting vendor commissions). I had the idea of upping the numbers by having a kick ass graphic designed.. The graphic came out beyond expectations. A truly amazing graphic, so I re-designed the head of the site, and incorporated the graphic instead of the ugly links.. Clicks sky-rocketed and conversions went drastically down.. I would say my own sales were 80% lower for the few days I had the graphic up and running.. I just took the graphic down and put up the text links again, but put them in a more visible place. I will weigh the performance again to see if it recovers.. NOTE: this experiment isn't affecting my affiliates who are making sales.. Their clicks don't even see the graphic and their sales stayed normal. Conclusion- Not known for sure yet, but it seems that if the teaser graphic is flashier than the site itself, conversions go down. Maybe people get the hint that I am trying to professionally sell them something instead of giving them recommendations, or maybe the graphic just attracted curiosity clicks instead of pre-sold people..
