Simple Exit Pop

A lightweight WordPress plugin that displays a responsive exit-intent popup ad — with separate desktop (16:9) and mobile (9:16) creative, frequency control, A/B testing, and built-in impression/click-through tracking.

Built for small businesses who want a simple, no-dependency way to catch visitors before they leave the site, without pulling in a heavyweight marketing plugin.

Features

• Responsive creative — automatically serves a widescreen image on desktop and a vertical image on mobile, using the browser's native <picture> element (no JS-based device detection needed for image selection).
• Exit-intent trigger — desktop uses mouseleave at the top of the viewport; mobile uses the visibilitychange event (tab/app switch) as a practical substitute, since true mouse-based exit intent doesn't exist on touch devices.
• Frequency control — choose how often the same visitor sees the popup (every page load, once per day/week/month, or once ever), enforced via a cookie.
• A/B testing — optionally split visitors 50/50 between two creative variants (A/B), each with its own image pair and destination link. Assignment is randomized once per visitor and persisted via cookie so repeat visits during a test period stay consistent.
• Impression + click tracking — every popup display and every click-through is logged via AJAX, broken out by device (desktop/mobile) and by variant (A/B), with a performance table (CTR included) right on the settings page.
• Zero external dependencies — pure PHP + jQuery (already bundled with WordPress core), no build step, no npm install.

Installation

1. Download the latest release zip (or clone this repo into wp-content/plugins/).
2. In WordPress: Plugins → Add New → Upload Plugin, select the zip, then Install Now → Activate. (If installing from a git clone instead of a zip, just make sure the folder lives at wp-content/plugins/simple-exit-pop/.)
3. Go to Settings → Simple Exit Pop.
4. Upload your desktop (recommended 1200×628) and mobile (recommended 1080×1920) images for Variant A.
5. Optionally set a destination link, adjust the show frequency, and/or enable A/B testing with a second image pair + link.
6. Save Settings and test on both desktop and mobile.

How A/B testing works

When enabled, each visitor is randomly assigned Variant A or B the first time the popup fires, and that assignment is stored in a cookie (mep_variant, 365-day expiry) so they keep seeing the same variant across sessions. Impressions and clicks are recorded per-variant, and a comparison table (impressions, clicks, CTR) is shown at the top of the settings page.

Frequency control

The popup won't reshow to the same visitor within the selected window (day/week/month/forever), tracked via a mep_popup_seen cookie. Setting frequency to "Every page load" disables this gating entirely.
