External Links Advertisement Note

External Links Advertisement Note adds a configurable note to links on the front end of your WordPress site.

Version 2.0 introduces a modern detection engine and a redesigned settings interface while preserving settings from the 1.x series.

Choose between three detection modes:

• All external links – marks HTTP and HTTPS links that lead away from the current site.
• Sponsored links only – marks links whose rel attribute contains sponsored.
• Only selected domains – marks links to domains you explicitly list.

You can configure:

• Marker text such as *, ↗, Ad, Sponsored, or Advertisement.
• An accessibility label for symbolic markers.
• Marker position before or after the link.
• Marker size, color, border, and underline behavior.
• Included and excluded domains.
• Whether image links are marked.
• Whether subdomains are treated as internal.
• Whether links inserted after page load are detected with MutationObserver.
• Simple CSS selectors that should never be marked.

The plugin does not rewrite destination URLs and does not automatically add nofollow, sponsored, target="_blank", or other link attributes.

Not every external link is advertising. This plugin displays labels according to your configuration. It does not provide legal advice and does not determine whether a disclosure is legally required.
