I haven't been writing for some time now, but I want to post this thing I know and I've experienced. I have had a affiliate website in the pills niche. I've made my own order buttons for with text: ORDER NOW. After some time got ranked on 2nd page of Google for the keyword and started receiving around 150-200 unique visits per day but had low conversion rate. What I did was changed the text of the order now button to: "Order now from official website" linking direct to the order page of the official site. After just 10 minutes I started getting better conversion rate. Hope this helps everybody that struggles with the affiliate marketing!
