MotoPress

This plugin allows you to optionally keep the last post modified date unchanged when you update the post in WordPress Classic Editor.
It adds datepicker and checkbox to the Publish panel of every post. If you select checkbox when you update the post, the last modified date will change; if not, this date will not change no matter how many times you update the post.
This is a helpful thing if you make only slight changes to the post and don’t want it to be noticed by the search engine crawlers or even in the post information publicly visible on your website.
Only use the plugin to keep the last modified date unchanged for minor changes. If you make a major change to a post, make sure to check the box to update the last modified date, thus making search engines aware of the update.

Freshtag lets you manually set and display a custom “Last Modified” date for any post, page, or product. 
Instead of always showing the original publish date, you can highlight recent updates — keeping your content looking fresh and relevant.
✅ Key Features:
<ul>
<li>Custom meta box in the post/page/product editor to manually set a “Last Modified” date</li>
<li>Automatically display the last modified date at the top or bottom of posts/pages</li>
<li>Hide the default WordPress “Published On” date</li>
<li>Shortcode <code>[freshtag]</code> to place the date anywhere in your content</li>
<li>Works with posts, pages, and WooCommerce products</li>
<li>Simple setup — no coding required</li>
</ul>
This is especially useful for blogs, news sites, and e-commerce stores where keeping content fresh builds SEO trust and user confidence.
How To Use
<ul>
<li>
Option A — Auto-insert (no code)
<ul>
<li>In your WordPress dashboard, go to Settings → FreshTag.</li>
<li>Under Display Position, choose Above the post or Below the post.</li>
<li>Click Save and refresh your site. You’ll see “Last updated: …” at the location you selected.</li>
</ul>
</li>
<li>
Option B — Manual placement
<ul>
<li>Shortcode (Classic or Block Editor): [freshtag]</li>
</ul>
</li>
</ul>
How it works: FreshTag reads the post’s Last Modified time (WordPress post_modified). Update your post (or adjust the Last Modified meta on the edit screen, if enabled) and the frontend will show the new “Last updated” time automatically.
<h3>Freshtag Pro (Coming Soon)</h3>
FreshTag Pro turns FreshTag into a full freshness monitoring system.
Planned Pro features:
<ul>
<li>Outdated content monitoring for posts, pages and custom post</li>
<li>Email alerts when content becomes outdated</li>
<li>Auto‑update post dates (modified or publish)</li>
<li>Drip updates to spread refreshes over multiple days</li>
<li>Updated content history and logs</li>
</ul>
