Before the experiment:
Amazon conversion rate = 4.15% (via Amazon.com)
Daily CTR = 16.45% (via addfreestats.com)
Conversion rate = 9.51%
Daily CTR = 38.72%
Before, I had the updated product prices posted on each product page right under the title of each article/product review. After examining and analyzing my addfreestats data, I wondered why the CTR was so low and people were leaving my site right after they arrived without clicking anything. I thought people immediately closed the page after seeing the price which I think too expensive for them. I am doing the same (closing the page after seeing the price of the product) so I assumed that this was the main reason why people were running away from my site.
I removed the prices and replaced it with "Click Here to See the Current Price" for non-discounted products, and "Click here for Discounted Price" for discounted products. Since Addfreestats provides instant data, I saw an abrupt changes on my CTR after several hours of changes, and saw big increase on conversion rate after 2 days. Lots of orders coming in. The same thing happened for the whole week and the succeeding week (2 weeks now).
I think most people react when seeing the price first before the product details that's why the "average time on site" was very low. Without giving them the exact price, they were curios to check it and when they landed to amazon site upon clicking that link, they are provided a lot of options if they find the price of the certain product expensive.
My site promotes only home appliances and before the changes, sales of non-appliance products was very low. After I made changes, sales on non-related products increased more than 2 folds in especially cheaper products like books, ipad covers, toys, etc.
I thought people who purchased before I made changes were people who really needed to buy that certain home appliance and were ready to enter their credit card details. After the changes, I thought people who were just doing window shopping for home appliances (and not yet ready to buy) were convinced to buy products with lower prices when they arrived at the amazon site...
Sometimes, small changes can big impact if you analyze the problem well and take action.. To those people who are running Amazon sites, you can try the same.. Good luck.
