Header (H1, H2, H3) Tags

The H tags define the content hierarchy of your pages. H1 essentially acts as the headline for the page, H2 are subheadings, and H3 are sub sub or tertiary headings. From a search perspective the engines tend to favour keywords that appear in the headers, most notably the H1 tag.

Beware ‘stuffing’ all of the headers on a page with repeats of the same keyword as this may be interpreted by the engines as spammy, but do use the headers as a reinforcement of the major keywords you have signalled through your title tags.
