I was reading that it was bad to have two h1 tags one page. I started looking at ways to make my post rank higher and noticed they all had double h1 tags. One was the Blog title and the other was the post title. How do I prevent this from happening. Example:http://dogfoodchat.com/large-breed-dog-food/
Yes you are right, more than one H1 tag can trigger a filter but I am not sure if this applies to your blog as the tags are placed in div tags referring to every article on page. Seems that the SEO plugin you are using does it. I have seen it on other blogs too and I am not sure if a change to a "better" plugin will change that. You can always change your configuration to just one article per page, I think this will resolve the problem.
