I am quite new to these approach in optimizing my HTML with Rich Snippets. I am not sure what is the differences of each of the list items below:
I got this code below example below, and I want to know what are the missing items or codes that could optimized a simple blog post that search engines can understand. I'd like to know all the rich snippets available for a blogpost.
<div id="blog_post" itemscope="" itemtype="http://schema.org/BlogPosting">
            <h2 itemprop="name headline">Post Title</h2>
            <div class="byline">
                Written by
                <span itemprop="author" itemscope="" itemtype="http://schema.org/Person">
                    <span itemprop="name">
                        <a href="https://" itemprop="url" rel="author">Author</a>
                    </span>
                </span>
                on
                <time datetime="2011-05-17T22:00" itemprop="datePublished">Tuesday May 17th 2013</time>
            </div>
            <div class="content" itemprop="articleBody">Content...</div>
</div>
