<p>This plugin adds <a href="https://schema.org/Event" rel="nofollow ugc">schema.org’s event markup</a> to All-in-One Event Calendar’s events.</p>
<p>According to <a href="https://developers.google.com/search/docs/guides/intro-structured-data" rel="nofollow ugc">Google</a>, when you provide structured data markup for your online content, you make that content eligible to appear in two categories of Google Search features:<br />
* Rich results—Structured data for things like recipes, articles, and videos can appear in Rich Cards, as either a single element or a list of items. Other kinds of structured data can enhance the appearance of your site in Search, such as with Breadcrumbs, or a Sitelinks Search Box.<br />
* Knowledge Graph cards—If you’re the authority for certain content, Google can treat the structured data on your site as factual and import it into the Knowledge Graph, where it can power prominent answers in Search and across Google properties. Knowledge Graph cards appear for authoritative data about organizations, and events. Movie reviews, and movie/music play actions, while based on ranking, can also appear in Knowledge Graph cards once they are reconciled to Knowledge Graph entities.</p>

<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 & 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’s algorithms.</p>
