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
relattribute containssponsored. - Only selected domains – marks links to domains you explicitly list.
You can configure:
- Marker text such as
*,↗,Ad,Sponsored, orAdvertisement. - 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.

Important
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.
