Instant Sitemap is a lightweight, zero-configuration plugin that gives you a single, powerful feature:
A one-click “Generate Sitemap” button in your WordPress admin (left menu Instant Sitemap).
When clicked, it:
– Instantly generates a static sitemap.xml file in your site’s root.
– Backs up the previous sitemap with a timestamped filename (e.g., sitemap-20250718-143500.xml).
– Counts URLs (before and after) and shows a live AJAX notice with the difference.
– Works with all public post types (Posts, Pages, CPTs).
– Loads scripts only on the plugin page for a lean, clean admin.
No settings. No bloat. Just click and done.
Why This Plugin?
Unlike bulky SEO plugins (Yoast, AIOSEO, RankMath), Instant Sitemap does only one thing – and does it fast.
It’s perfect for developers, minimalists, or anyone who just wants a quick, static sitemap for Google & Bing.

Upload the plugin from Plugins → Add New → Upload Plugin.
Select “mmedia-instant-sitemap.zip” and click Install Now.
Activate the plugin and open Instant Sitemap settings.
Click Generate Sitemap to create your complete sitemap.
After generation, the results screen shows: total URLs, number of updated URLs, and previous vs new counts.
When you add or remove content and generate a new sitemap, the interface updates to show Previous URLs, New URLs, Updated URLs, and the Difference.
On your server, you’ll see the new sitemap.xml plus archived versions automatically renamed with a timestamp (sitemap-YYYYMMDD-HHMMSS.xml).
