First-Click PopUnder Script

Built for webmasters who want more revenue without wrecking the user experience.

Price: $19 one-time — use on unlimited domains you own.

Clean, lightweight pop-under script that stays out of the way. No bloat, no external libraries, no control panel. Drop in one PHP file and your first external click per session fires a rotating offer in the background (where the browser allows it).

What it does

• First external click only — triggers when a user clicks out to another site.
• Pop-under behavior — tries to send the new window behind your site.
• Offer rotation — add multiple affiliate URLs, one is chosen at random.
• Session-aware — only on the first pageview of that browser session/tab.
• Frequency control — set to 0 for every new session, or once per X days.
• Exclude URLs — skip checkout, members area, or any links you choose.
• Works everywhere — desktop, tablet, and mobile (subject to popup rules).
• No dependencies — plain PHP + vanilla JS, easy to edit and customize.

Requirements

• PHP hosting (standard cPanel / shared hosting is fine).
• Ability to edit your theme/footer template and upload one PHP file.

Quick install (2–3 minutes)

1. Upload the file
   Upload first-click-popunder.php to your site root (same folder as index.php).
2. Include it before </body>
   In your footer template, add:

   <?php include $_SERVER['DOCUMENT_ROOT'] . '/first-click-popunder.php'; ?>

3. Edit your offers
   Inside first-click-popunder.php:

   $popup_offers = array(
       'https://your-affiliate-offer-1.com/...',
       'https://your-affiliate-offer-2.com/...'
   );
   
   // 0 = no multi-day limit (once per session)
   // 1+ = once per X days per visitor
   $cookie_days = 0;

4. (Optional) Exclude pages
   Skip certain links (members, checkout, etc.):

   $popup_exclude_links = array(
       '/members',
       '/checkout',
       'paypal.com',
   );

Upload, include, set your offers — done.
