I understand that it takes time for Google to show rich snippets for a website. But, I want to make sure that I'm marking up my structured data correctly in the mean time. Is the following code okay for a review? Can it be done better?
<main itemscope itemtype="http://schema.org/Review">
<meta itemprop="inLanguage" content="en-CA">
<article itemprop="reviewBody">
<header>
<img itemprop="thumbnailUrl" src="/review/pushmo.jpg" alt="Pushmo">
<h1 itemprop="name"><span itemprop="itemReviewed" itemscope itemtype="http://schema.org/Thing"><span itemprop="name">Pushmo</span></span> Review</h1>
<h2 itemprop="headline">This sumo wrestling cat has children to rescue</h2>
<p>Reviewed by <a href="/profile/crazyaj" rel="author" itemprop="author" itemscope itemtype="http://schema.org/Person"><span itemprop="name">A.J. Maciejewski</span><meta itemprop="url" content="http://example.com/profile/crazyaj"></a> on <time itemprop="datePublished" datetime="2014-09-03T20:33:03-07:00">September 3, 2014</time></p>
<meta itemprop="description" content="Review for Pushmo on 3DS. This sumo wrestling cat has children to rescue. Pushmo proves that Nintendo still has the ability to produce great new properties.">
<meta itemprop="keywords" content="Review,3DS,Pushmo">
</header>
<p>blah blah blah</p>
<div itemprop="reviewRating" itemscope itemtype="http://schema.org/Rating">
<span itemprop="ratingValue">8.4</span> <small>out of <meta itemprop="worstRating" content="1"><span itemprop="bestRating">10</span></small>
</div>
</article>
</main>
As a side note, I noticed when I search for "review site:example.com" the rich snippets appear but they don't when I don't use "site:example.com". Does anyone know why this is?
Thanks again for reading. Any help would be greatly appreciated.
