Hi buddies, I have a small niche site earning with amazon associate program. The daily visiotr number is about 200, but I just get around 20-30 click to amazon (so CTR is about 10-15%). I heard from many people that it's totally possible to increase CTR up to 50-60%. However, so far, I have tried different version (CTA button, text link, etc) but the results almost keep unchanged. So could anybody can suggest me what I should do change to get better result, and how to do A/B test effectively, are there any "special tips" here? Any help will be appreciated, Thanks!
