I had a small thin site with an excellent written review that was getting a 10% vistor to conversion rate. Aka 10 sales per 100 visitors to my site. Just managed to get the site back ranking number 4 or 5 in google first page. I want to add content to target more traffic and make it more authorative, however the basis of the site is around reviewing a product. Kind of a dumb question but what type of content should I be adding? The entire focus of the site is to sell this one product so I dont want to add content that is just going to distract users from that purpose. Pretend the site is reviewing a "fat burner" product. Would adding random articles about "benefits of vitamin a" or benefits of "cod liver oil" be beneficial? Not really sure how to do this.
