Does one thing: disables WP robots meta tag.
Activate this plugin to disable the robots meta tag (added in WP version 5.7).
Features
<ul>
<li>Lightweight – only one line of code.</li>
<li>Simple to use – activate and done.</li>
<li>No settings to worry about.</li>
<li>Easy peasy.</li>
</ul>
Why is this useful?
Because most existing WordPress sites (i.e., a LOT of sites) already have robots meta tags taken care of, either via plugin or theme enhancements. So when upgrading to WordPress 5.7, there may be conflicting or redundant meta tags, which may not be optimal for SEO. This simple plugin disables the new WP robots meta tag completely, so it will not interfere with existing meta robots configurations. Or maybe you are setting up a new site and don’t want WordPress to add any meta tags to your pages. Whatever the reason, this plugin will do the job with a click.

This plugin will issue a HTTP <code>410</code> response to requests for articles that no longer exist on your blog. When you delete a post or page, it records the URL for that page and issues a <code>410</code> response when that URL is requested. You can also manually manage the list of obsolete URLs.
The <a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.4.11" rel="nofollow ugc">HTTP Specification</a> defines the <code>410</code> response header for use when a resource has been permanently removed. It informs robots visiting your site that the requested content has gone, and that they should stop trying to access it.
If you come across any bugs or have suggestions, please use the plugin support forum. I can’t fix it if I don’t know it’s broken! Please check the <a href="https://wordpress.org/extend/plugins/wp-410/faq/" rel="ugc">FAQ</a> for common issues.
