29/05/2025 0 59 3 min read

Init Ad Engine is a WordPress plugin that lets you insert ads into virtually any location on your site — precisely, flexibly, and without being restricted by your theme or page builder. From popups, floats, stickies, and popunders to global header/footer code, this plugin covers every ad need for content-driven websites.

Main Features

15+ ad positions: PC, Mobile, before/after content
Popups with 3 display modes: on load, after delay, exit intent
Affiliate Gate – lock part of the content and require ad interaction to continue
Popunder opens a new tab on first click, with cooldown control
Fallback code: supports AdSense, AdX, Dable, third-party JS
No conflicts with other plugins, no broken HTML output
Clear admin UI with tabs to manage each ad group
Pure Vanilla JS, only loads when needed

Supported Ad Positions

Init Ad Engine groups ads into three main categories:

PC Group

Billboard
Balloon Left / Right
Float Left / Right
Catfish Top / Bottom
Popup Center PC
Before / After Content (PC)

Mobile Group

Mini Billboard
Sticky Top / Bottom
Popup Center Mobile
Before / After Content (Mobile)

Special Group

Popunder – opens a new tab on first click
Global Header & Footer code – insert any custom HTML/JS

Full Control Over Popup Behavior

Popups can be configured to display:

Immediately on page load
After a custom delay (in seconds)
When the user intends to leave (exit intent)

You can also define a delay between popup displays to reduce intrusiveness.

Fallback Code – Smart Backup for Ads

If you’re not using image banners, you can insert HTML or JS from third-party networks. Fallback code acts as a backup ad slot — perfect for platforms like AdSense, AdX, or custom embed content.

Affiliate Gate – maximize engagement

This feature allows you to hide part of your content (e.g. a chapter or post section) and replace it with a customizable ad block containing a banner, link, and message. Users must click to continue reading. You can choose from 4 display modes: always show, hide after click (with timeout), random chance, or every X pages.

- Refactored tab-switching into a unified activateTab() function for cleaner logic and easier future maintenance.
- Fixed scroll/height jump issues on the Popunder & Global tab for a smoother user experience.
- Preserved all existing markup and option structures to ensure 100% backward compatibility with previous versions.
- Minor code cleanup and internal stability improvements to prepare for future expansions.
1.3 – Multi-Link Support & Random Selection
- Affiliate Gate now supports entering multiple links separated by commas (,) — one will be randomly selected each time it’s displayed.
- Added a helpful description under the input field: “Enter multiple links separated by commas (,) to display them randomly.”
- Introduced a new helper function pickAffiliateLink() that normalizes, decodes, and randomly selects a valid http/https link (supports %20 in strings).
- Improved link handling for better consistency while keeping full backward compatibility.
- Minor code cleanup and improved reliability for future extensibility.
1.2 – Security & New Filters
- Security improvement: Global head & footer injections are now filtered with wp_kses using a custom allow-list (late escaping).
- New filter init_plugin_suite_ad_engine_use_kses – toggle escaping of snippets (default: true).
- New filter init_plugin_suite_ad_engine_allowed_tags – extend or modify the list of allowed tags/attributes.

- Supports 4 display modes: always-on, hide after click (with expiration), random by %, and every X views.
- Added custom step list – specify exactly which pageviews should trigger the gate (e.g. 1,3,5).
- New blur overlay option – insert a semi-transparent clickable layer on any element using a CSS selector, with its own step logic.
- Step tracking for both gate and overlay uses persistent localStorage, auto-reset after expire_hours.
- Refreshing the same page will no longer increase the step counter – only new pageviews are counted.
- Customizable content selector to define which part to block (default: .entry-content).
- Inline JS config injected in the <head> to prevent layout shift when content is toggled.
- New filter init_ad_engine_should_enqueue_affiliate_gate lets themes control when to enqueue the gate logic (e.g. only on chapter pages).
