[Plugins: WP SEO / WooCommerce] Help with getting a Good rank

First I am running WP v3.8.4 on the site in question, but that wasn’t in the drop down

I’m new at SEO and cannot figure out what I’m doing wrong when using WooCommerce. I’ve tried everything I can think of and still cannot get a Good with green button rank on any WC page. Most I can get is an OK, with some poor.

When I set up a new item, I use the description box and only have the image of item on the page. When an item is clicked on, it opens that page with image, h1 title, description and options to select to add to cart. See example below

It’s acting as if one of the plugins is canceling out the other. Is there a function/hook I need to use that I haven’t found to correct this? I’m at a loss here and would like to know how to get that Good ranking on all my store items. Preferably without having to use another plugin. Thanks!
