Hello all. That's my story. I built a ClickBank product review site few months ago without doing heavy link building. The site just ranked in the bottom part of first page of Big G's SERP for the product name and used to make 1 to 2 sales per day. And I earned a few money out of that. Then I decided to build some links to the site a month before and as expected it ranks higher now to the top 3 and traffic grows accordingly. I use G Analytics for tracking purpose. Now the myth is that - I only got 2 sales in the last 14 days. I go to ClickBank and see the gravity of that product is actually increasing. Why I don't get more sales? I get more targeted traffic and the ranking is higher now. Assuming ClickBank is not shaving, my conclusion is that ranking higher doesn't help all the time. Just make sure your sites rank at the middle or bottom part in the first page of SERP maybe the best. Why? Because visitors do not buy after reading the first SERP result, they may actually click to the sales page after reading a few product reviews which are probably found at the bottom part of the SERP. Remember, commission is rewarded to the last affiliate who redirect to visitors to the sales letter. I know I maybe wrong and just want to see everyone's experiences here.
