Super Cool Ad Inserter Plugin

This WordPress plugin gives site administrators a way to insert widgets such as ads, newsletter signups, or calls to action into posts at set intervals.

The plugin registers a configurable number of widget areas.

The plugin can programmatically insert these widget areas into posts when the page is rendered. This setting can be overridden on a per-post basis via a post meta box or a filter.

If the programmatic insertion doesn't work for a particular post, users can choose to place specific widget areas at specific spots in the post using shortcodes or blocks.
