This plugin lets you laser focus your banners, advertisements, promos and affiliate promos in relevant posts that you choose. When you put out a quality review or are talking about a specific product, people are more open and ready to checking out the product when you invite them to. Take it a step further. Make your call to action bolder or place a banner ad directly in that post instead of showing other ads that may not be relevant.
Features
<ul>
<li>Use HTML or Javascript ads</li>
<li>Includes the option to fall back to a default advertisement if no ads are found for that post (optional)</li>
<li>Automatically place ads before, after content or using widgets</li>
<li>For finer control, you can choose to use a shortcode to include the ad directly into your post</li>
</ul>

This made the widget selection much easier. With this plugin activated we can select widgets to show specifically for one page / post / or custom post type.
