<h3>External services</h3>
This plugin connects to Google’s sitemap ping service to notify Google when new content is published.
Google Sitemap Ping
<ul>
<li>What it does: Notifies Google that your sitemap has been updated so new content can be discovered and indexed faster.</li>
<li>What data is sent: Your sitemap URL (e.g., <code>https://example.com/sitemap_index.xml</code>).</li>
<li>When it is sent: Automatically when a new post is published for the first time. A 60-second debounce prevents duplicate pings.</li>
<li>Service provider: Google LLC</li>
