Hey there.
Here's the biggest tip I can give you: stop thinking about what will please Google and start thinking about what will please your users. Make them happy, and Google will follow.
A useful exercise is to have a whiteboard next to you, and every time somebody asks you a question about a product, category, brand or similar add a tally mark next to that. Whenever you get a chance to write some new content start with the one with the most tally marks. It's the one your customers want to find content for the most!
Often this content is best placed in the product description themselves (I've written about the frustrations I have where shops ignore this kind of detail at) but could also be static pages or blog posts.
Be in touch with your customers - best trick in the book.
