Description

Very simple WordPress plugin, that uses built in function to filter element attributes. It will add human invisible / search engine visible schema.org itemprop code to content (via META tags).

<!-- Itemprop WP 3.4.0 by Rolands Umbrovskis http://umbrovskis.com -->
 <meta itemprop="name" content="Title of the Article" />
 <meta itemprop="url" content="http://fulllink.example.com/seo-optimized-article/" />
 <meta itemprop="image" content="http://fulllink.example.com/seo-optimized-article/example.jpg" />
 <meta itemprop="author" content="http://fulllink.example.com/author/authorusername/"/>
 <meta itemprop="description" content="excerpt from post OR first 170 symbols (with full word), ..." />
 <meta itemprop="datePublished" content="2012-09-13 19:17:21"/>
 <meta itemprop="dateModified" content="2012-09-29 13:33:25" />
 <meta itemprop="interactionCount" content="UserComments:356"/>
<!-- Itemprop WP 3.4.0 by Rolands Umbrovskis http://umbrovskis.com end -->
</span>

<div itemprop="review" itemscope itemtype="http://schema.org/Review">
    <meta itemprop="name" content="Item Title is greate!" />
    <meta itemprop="author" content="Rolands Umbrovskis" />
    <meta itemprop="datePublished" content="2011-03-25" />
    <span itemprop="reviewRating" itemscope itemtype="http://schema.org/Rating">
        <meta itemprop="worstRating" content = "1"/>
        <meta itemprop="ratingValue" content="4.5" />
        <meta itemprop="bestRating" content="5" />
    </span>
    <span itemprop="itemReviewed" itemscope itemtype="http://schema.org/Thing">

        <span itemprop="offers" itemscope itemtype="http://schema.org/Offer">
            <meta itemprop="price" content="55.36" />
            <meta itemprop="priceCurrency" content="USD" />
            <link itemprop="availability" href="http://schema.org/InStock" />
        </span>
    </div>
    <meta itemprop="description" content="Great Item Title for the price." />
</div>

How does it work?

This asumes that Your page is not fully integrated with HTML5's data properties for microdata. This plugin will create small code inside Your full content, with extra microdata from schema.org. This will be ONLY on singular pages - post, page or your custom post type.

Once we are on singular page:

  • NEW in 3.3.0 itemprop="review".
  • we will extract from it EXCERPT.
  • If You haven't provided excerpt, plugin will look-up for post content, and downsize it to 170 symbols up to full word.
  • If your content consist ONLY of shortcode, it will strip it out, and leave empty content. :(
  • If we have empty content, from previous step, we will use post title. Not best choise, but at least we have some description.
  • If Your post do not have even title, plugin will giveup and your description will be ampty. (This ir very bad :') )

Other options, like datePublished, UserComments, url are taken from post
