H1 and H2 the same – problem or not?

The h1 tag should be the most important thing on the page and your theme is using it for the logo but is wrapping the page title in h1 tags then hiding them via display none and replacing with the logo image. Your post titles are in h2 tags so on single post pages you have the same content in both places..

I don’t think it is very good for SEO on your home page for the word homepage to be wrapped in h1 tags. it would be better if your site name was in h1. On the interior pages I think it would be better to just use it once for the posts title and not for the logo.
