Outputs data stored in HeadSpace2 post meta without requiring HeadSpace2. This allows one to remove the now-unmaintained HeadSpace2 plugin without losing the data associated with legacy content.
The HeadSpace2 plugin is no longer maintained and generates many warnings when used with PHP 7. With this in mind, and without judging the original plugin, I created this option to preserve the plugin’s output for SEO purposes. The plugin does not allow HeadSpace2 data to be edited; it only allows search engines to continue accessing it.
Note that many current SEO plugins also handle migration from HeadSpace2, but since I don’t use any such plugins on my network, I created this alternative.
For a full list of the HeadSpace2 data that’s supported, see the FAQ.

WordPress updates the post/page modified time only when you save/update the post/page in the editor. If you have shortcodes or blocks that create dynamic content (ie. returning content from queries, files, feeds, etc.), the WordPress post/page modified time will not reflect these dynamic changes.
<h4>The Solution:</h4>
The JSM Accurate Modified Time for SEO plugin monitors the post/page content for changes and updates the WordPress post/page modified time as required.
If you use a social and search optimization plugin like WPSSO Core, Yoast SEO, The SEO Framework, Rank Math SEO, All in One SEO, etc., the Open Graph <code>og:updated_time</code> and <code>article:modified_time</code> meta tags, along with the Schema markup <code>dateModified</code> property, will show accurate modification times when shortcodes or blocks updates your post/page content.
