In this post, we’ll know how to integrate Schema.org Article markup in a WordPress powered blog – provided that you are little familiar with normal WordPress theme customization.
Schema.org Article markup in WordPress posts
No WordPress plugins can implement Schema.org Article markup in your posts perfectly. You have to dig into the code as it needs manual customization. Through this tutorial, I’m trying to make this whole editing process easier and simpler for you.
Note: Before proceeding to the tutorial, make sure you have created a back-up of your WordPress theme to avoid any code loss.
Starting off, we need to edit the file that is responsible to display our single post. Basically,
single.php is meant for that purpose, so we are beginning up by editing our
single.php is making use of a separate file (eg.
content.php to display the post, you should edit that separate file to implement this tutorial. If you’re still unsure about what file you have to edit, contact your theme developer to know that.
Find this line or similar in the file:
<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
Note that it’s not necessary that the code carries the
<article id=.. tag, it may also start with a simple
<div id=.. tag. Next, add the
itemtype microdata in that line like below:
<article itemscope itemtype="http://schema.org/Article" id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
<meta itemprop="name" content="<?php the_title(); ?>" /> <?php if(function_exists('the_post_thumbnail')) : ?> <meta itemprop="image" content="<?php echo wp_get_attachment_url(get_post_thumbnail_id()); ?>" /> <?php endif; ?> <meta itemprop="url" content="<?php the_permalink(); ?>" /> <meta itemprop="author" content="<?php get_the_author(); ?>"/> <meta itemprop="description" content="<?php echo get_the_excerpt(); ?>" /> <meta itemprop="datePublished" content="<?php the_time('F j, Y'); ?>" /> <meta itemprop="dateModified" content="<?php the_modified_date('F j, Y','',''); ?>" />
Final step, save the changes. All done! Now, your WordPress posts are powered by Schema.org Article markup!
