Leaving Notice Popup For External Links

FAQ

Will this work with all themes?

Yes, Leaving Notice Popup is designed to be compatible with all WordPress themes. The popup is added to the page dynamically and does not interfere with your theme’s design.

Does this work for all external links?

The plugin works for all standard links that lead to external domains. It will not trigger for special links like mailto:, tel:, javascript: or anchor (#) links.

Can I exclude certain domains from triggering the notice?

Yes, in the plugin settings you can add domains to a whitelist. Links to these domains will not trigger the leaving notice popup.

Can I exclude specific URLs from triggering the notice?

Yes, you can add specific URLs to a whitelist in the plugin settings. These exact URLs will not trigger the leaving notice popup.

Can I show the notice only on specific pages?

Yes, you can use the externallinknotice_allowed_pages filter for specific pages (Pages, Posts, Custom Post Types).
Example:
add_filter( ‘externallinknotice_allowed_pages’, function( $pages ) {
return array( 10, 25 ); // Replace with your Page IDs
} );
Note: This will ONLY work for singular pages/posts. It will not work for archives or categories.

Can I show the notice on Archives, Categories, or Home page?

Yes, for more advanced control, use the externallinknotice_is_enabled filter.
Example:
add_filter( ‘externallinknotice_is_enabled’, function( $enabled ) {
if ( is_home() || is_archive() ) {
return true;
}
return $enabled;
} );

Will the notice appear when clicking on internal links?

No, the popup only appears when users click on links that lead to domains other than your own website.

Does the plugin work with embedded content or iframes (YouTube, Google Maps, etc.)?

No, the Leaving Notice Popup does not detect or intercept links inside embedded content or iframes. This is by design and is a technical limitation that applies to all similar plugins. Here’s why:

Embeds and iframes (such as YouTube videos, Google Maps, social media widgets, or any other third-party embed) are sandboxed content rendered entirely by the external provider’s server inside an isolated frame. They are not standard anchor (<a>) links on your page — they are self-contained mini-pages loaded from a third-party domain. Because of browser security policies (specifically the Same-Origin Policy), no WordPress plugin or JavaScript running on your site can access, modify, or listen to click events happening inside an iframe from a different domain.

In short:
* Embedded/iframe content is not detectable as an external link by our plugin because it is not a clickable link on your page.
* Attempting to intercept iframe interactions could break the embed’s functionality entirely (e.g., stopping a YouTube video from playing or a map from being interactive).
* The plugin is intentionally scoped to standard HTML anchor links (<a href="...">) that exist directly in your page’s DOM.

If you are using embeds and notice that those links do not trigger the popup, this is expected and correct behaviour. The popup will continue to work for all regular external links on your page.

My website uses advertisements or ads. Should I use this plugin?

We do not recommend using this plugin on websites that rely on advertisements or ad networks for revenue. Here’s why:

Ad clicks are essential for generating revenue on your website. Since ads typically link to external domains, the Leaving Notice Popup will treat those ad links like any other external link and display a warning popup when a visitor clicks on them. This can significantly disrupt the ad click flow and negatively impact your ad revenue. However, you can give a try whether it works for you or not as some ads uses embed and it will not trigger the popup as mentioned in the FAQ section.

While you could technically whitelist all the domains and URLs used by your ad networks, this is not practical because:
* Ad networks serve links from a large and constantly changing pool of advertiser domains.
* You would need to manually whitelist every single ad domain or URL path, which is nearly impossible to maintain.
* Missing even one domain would cause the popup to appear on that ad, potentially costing you revenue.

Our recommendation: If your website’s primary monetisation strategy involves display ads, native ads, or any click-based advertising, we strongly advise against installing this plugin to avoid interfering with your ad revenue.

Is the plugin GDPR compliant?

Yes, the plugin does not collect, store, or process any personal data.
