Short & long descriptions

Hi I have a concern!
For each of my products the description is written in the short description and is seen to the right of the product image. I have delivery information written in the long description and can be viewed below the image. My concerns are that when I enter keywords in the seo section the keyword can be seen everywhere but a green NO for content. Is this bad for SEO? I’m struggling to get seen in google, can they see my content not? I mentioned it to the website developer and he said no but I get the feeling he just fobbed me off.
Hope it seems clear, very difficult to explain.
Thanks
