SEOptimer's Free Header Tag Checker Tool. Check that you are using Header Tags.
The H2-H6 Header Tags are an important way of organizing the content of your page and signaling to Search Engines the longer tail topics your page should rank for.
We recommend including at least 2 other Header Tag levels on your page (such as H2 and H3) in addition to the H1. It is useful to also include important keywords in these Header Tags. These would be added to the core content section of your page.
