Should I add a new unique page for the same product for each retailer I recommend?

Hi Guys,

First off thanks in advance for any help you can give on this.

I have a review site. At the moments its doing well, I am attempting to grow it but I do not want to do anything that will trigger a google penalty. As such I would love your opinions on the best way for me to add new retailers and products in a way that will not penalise the site etc.

The question is should I do a new page for each of the products and just link to each of the individual retailers? This would lead to around 5 pages each with unique content and each linking out to different retailers but all for the same product. The plan is after we find the page that gets the most traffic we will then optimise that with a long review of the product (1,000 words etc).

The plan to grow the site was to do the content in the below order;
1 = Add as many unique product reviews for as many retailers in our sector as possible. We can see what sticks this way.
2 = When a review makes a sale or gets traction we turn it from a short review to a very comprehensive 1,000+ word one.
3= Where we have multiple retailers for the same product we will then turn the most trafficked long reviews of that product into the main page. We will then link out to all the retailers of that product from that one page.

My question; Is that a good way to do things or will it trigger a penalty or something from google? I am building this white hat and for the long run so the last thing I want to do is shoot myself in the foot.

Thanks in advance for your time and help.
