Same template site same products but different content?

[dynamic08]

for the sake of this post I am selling lighters.

I have 3 domains

small-lighters.com

medium-lighter.com

large-lighters.com

On all of the websites I have the same template same images etc and same products. The only difference is the way the content is worded described etc different bullet points.

My domains are all strong keyword domains not spammy and bring in type in traffic. Is it ok to continue in this manner in your opinion?

This is a solid SEO strategy as long as the content is unique. Ways you can additionally add value is by making sure you are changing product names and titles;url descriptions; product image titles; meta tag descriptions; etc.......

Some of your competitors might see it as an attempt to generate more results for the same business...because of this you should be aware of some of the giveaways of this strategy. Here is a post from a  fellow seomoz'r that gives some examples: (see link below)
