The Add Widget After Content WordPress plugin, available from the WordPress plugin repository, makes it easy for you to add the After Content Widget Area (also known as a sidebar) after your content. You can prevent the after content widget from showing on specific post types (post, pages, etc.) from the editor page and the plugin settings page. You can even add multiple widgets to the After Content Widget Area. Until now you could not control the individual widgets.
Using Widget Logic To Control Widgets
Widget Logic allows you to control all your widgets using PHP. WordPress offers you “conditional tags” that you can type in to tell a widget where it should be added or removed. Here is an example condition is_single() && in_category( ‘podcast' ). You can learn more about conditional tags in the WordPress Codex.
Using AWAC Widget Controls
If the PHP required to use Widget Logic is not something you want to tackle, you should try AWAC Widget Controls an add-on for Add Widget After Content. The settings for AWAC Widget Controls appear after you add widgets to the After Content Widget Area.
Add Individual Widget After Content
Add a different call to action after your content. You can add a different call to action based on the post type. One widget can show after content on single posts. A different widget can show after content on all pages.
Remove Individual Widget After Content
You could also remove a widget after content on posts with a specific category. This gives you even more control of an opt-in for your readers to subscribe or even a banner ad.
If you are comfortable with PHP than Widget Logic will give you the control you need. But if you want to control your widgets after your content without having to fuss with PHP, AWAC Widget Controls is the perfect solution.
