Structured Data for Schema.org

<p>Structured Data for Schema.org helps you add valid Schema.org markup to your WordPress content. This improves how search engines understand your content and <strong>may qualify for Google Rich Snippets</strong> (depending on schema type and page structure).</p>
<h4>Supported Schema Types</h4>
<ul>
<li><strong>HowTo</strong> — Step-by-step tutorials (Google Rich Result eligible, 1 per page recommended)</li>
<li><strong>FAQPage</strong> — Questions &amp; Answers (Google Rich Result eligible, 1 per page limit enforced)</li>
<li><strong>ItemList</strong> — Ordered/unordered lists (Google Rich Result eligible)</li>
<li><strong>CreativeWork</strong> — General content (SEO only, no Rich Result)</li>
</ul>
<h4>Important: Google Rich Results</h4>
<p>Not all schema types guarantee Rich Snippets. Google has specific requirements:</p>
<ul>
<li><strong>HowTo:</strong> Best results with ONE main tutorial per page</li>
<li><strong>FAQPage:</strong> Only ONE FAQPage schema per page is eligible for Rich Results (plugin enforces this)</li>
<li><strong>ItemList:</strong> Works well for top-10 lists, product collections</li>
<li><strong>CreativeWork:</strong> Helps SEO but does not trigger Rich Results</li>
</ul>
<p>This plugin generates <strong>valid Schema.org markup</strong>. Rich Result eligibility depends on your content structure and Google&#8217;s algorithms.</p>
