GPM Short URLs Redirector

This plugin creates a custom post type whose single URLs immediately redirect to a specified external link using a permanent 301 redirect.

Key Features:

Dedicated CPT: Introduces “URLs Redirects” for separation from standard posts.

301 Redirects: Uses permanent redirects for SEO-friendly link juice transfer.

Custom Slug: Defaults to the /go/ base slug (e.g., yoursite.com/go/my-product).

Secure: Implements nonce checks and permission verification on save operations.

Upload the gpm-short-urls-redirector.php file to the /wp-content/plugins/ directory.

Activate the plugin through the ‘Plugins’ menu in WordPress.

Navigate to the new Link Redirects menu item in your WordPress admin.

Click Add New and enter a title for the slug (e.g., my-link).

Enter the full external destination URL in the provided meta box.

Publish the post. Your new redirect link is ready!

Note: If your redirect links do not work immediately after activation, navigate to Settings > Permalinks and click ‘Save Changes’ once to flush the rewrite rules manually.
