More and more search engines are prioritising websites and pages that have relevant content (text) on the pages. Some site audit programs will flag up pages that have a low ratio of text (content) to the code that generates the page (HTML). 

This can be a good thing and something you want to investigate - for example, a page that has one large image advertisement on it and nothing else will be ranked a lot lower than a page with a lot of relevant text, e.g. a news article or a technical document. 

It's up to you whether this is cause for concern, as on a retail site there will be some pages which will not have a lot of content but are still necessary. For example, a categories page with a list of thumbnail images linking to sub-categories will rank low in this test, but there's not a lot you can do apart from perhaps adding in a group description in the Product Manager.
