If you want the itemprop=”headline”, you would use this:
<div class="grid-container grid-parent">
<header class="entry-header">
<h1 itemprop="headline" class="entry-title">Android-Ice Cream-Sandwich</h1>
</header>
</div>
If you don’t want it to say “Android-Ice Cream-Sandwich”, you can change it to whatever you like.
What we’re doing is adding an overall H1 for you entire blog.
You don’t want your individual blog titles to be H1s, as you’re only supposed to have one on a page.
If each blog post title was an H1, you would be dinged by Google for having too many.
