Widget Locationizer permits you to define where you want your widgets to appear. You may specify the tags, categories, and page/post IDs for which a widget will be displayed. It also provides an option to exclude the widget from being displayed on selected tags, categories, and post/page IDs. Furthermore, you can assign a nofollow or dofollow status for a widget's contents too.

The following is how the plugin decides if a widget should show or not:

• Is it a tag page and the tag is in the list of tags for which to show the widget? If so, show the widget.
• Is it a category page and the tag is in the list of categories for which to show the widget? If so, show the widget.
• Is the page a single page (a single post/page, basically)? If so, is the post/page ID contained in the list of post/page IDs that were entered (if any)? If so, show the widget.
• Is the page a single page, no post/page IDs have been entered for the widget, and the Show on Other Pages option has been selected? If so, show the widget.
• Is the page none of a tag page, category page, or single page and the Show on Other pages option has been selected? If so, show the widget.
• Is the page a single page and is tagged or categorized with a tag or category from the list of tags or categories entered for the widget? If so, show the widget.
• Otherwise, don't show the widget
