By conversion rate I mean these things: - Conversion of visitors on your website into clicks (seen in GA) - Conversion of clicks into sales (seen in Amazon Associates account) Please share average price of your promoted products as well. I have a couple of Amazon sites for a couple of months, average conversion of clicks into sales is 4%. $20 to $100 (5%) products obviously convert better than those for $5000 (300 clicks, 0 sales so far for me). The uglier the site is, the better conversion rate of visitors into clicks is for me. I have struggled for a lot of time to convert ProReview theme into something that really attracts clicks, but I have 20% conversion rate (clicks/visitors) right now, while the ugliest HeatMap WP theme with a little tweaks and a design from 90s converts at 80% right now.
