Product page has insightful content of the product but the homepage and main product category page's also have the same content but in a short versions. Is there any possibility that Google is going to consider them as duplicate content?

So far we have done this. Rank for almost all main keywords in our blog's field. I am not saying the top position for all of them but most of them in our country.
Cleaned up all the link profile.
Do SEO for each and every product page. And also overall on-page SEO.
Actively participating and promoting in social media.
Guest post and market through forums to build authority.
Continuously build unique content and seek good backlinks from relevant pages.

Our conversions are so far good. We are making profit. But we want to increase it. What do your guys suggest?
