With the Use Hashtags plugin, you can easily use hashtags in your content (and your excerpt). Just type # plus a word, and the plugin will automatically convert it to a link.
The link send the user to the website search page, showing additional content that also uses that hashtag.
This can enhance the user experience, as it creates a new navigation layer inside your content.
<ul>
<li>There is no need to maintain the hashtags, just add them to your text, and it’s done.</li>
<li>This plugin is non-destructive, so it does not make any changes to how your content is saved. Only when the content is presented, the link will appear for the visitors.</li>
<li>This plugin does not generate external links.</li>
<li>Tested with selected core blocks.</li>
</ul>

<ul>
<li><a href="https://wordpress.org/themes/twentytwentytwo/" rel="ugc">Twenty Twenty Two theme</a>.</li>
