How do you actually utilize H1 tag in Wordpress, do you actually put the tag in every post title, as in <h1>post title</h1>? Is that how you should do it for SEO purposes... I dont usually do this because they dont work well in some wordpress themes as the titles in the sidebar really appear huge because of the tag...although in other themes, they are fine....
you can use he for post titles but i think the best one is like this: - h1 for blog title(on all pages) - h2 for post titles.
in header.php, use this code: <h1><a href="<?php echo get_option('home'); ?>/"><?php bloginfo('name'); ?></a></h1>
Nope. Watch the video by Matt Cuts. My site has 11 h1 tags per page. 10 for post titles and 1 for site title. Check out all popular blogs out there, they use h1 for post title.
