<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>

This plugin will make it possible to use tags as <code>meta keywords</code>. Under <code>Pages</code> you will find a new meta box called <code>Keywords</code>. 
By activation the plugin registrates a separate taxonomy which is independent from post tags. 
Today’s search engines don’t use <code>meta keywords</code> as a criteria at all, but who knows for what they will be good in future 😉 
For me tagging is necessary to bring pages in relation and gives me the possibility to save my tags redundant in the database.
