I've been investigating and this is what say Google about this error, we think that our articles are fine.
Google doesn't and, it is giving you advice on how to fix them.
Make sure you don't use frequent <br> and <p> tags within your paragraphs.
Interesting that Google is suggesting the above. That means they are using a semantic analysis at some level and they can't determine what the article is about. Using the proper semantic HTML elements appears to be the fix for this.
I actually find this to be rather exciting news - written confirmation that semantic analysis is being used at this level. :)
