There are a ton of WordPress plugins out there, it’s hard to find the gems. I found this plugin awhile back, and it’s completely under featured. Widget Context lets you pick which pages if not all of them you want a widget to appear. It’s great if you want to keep certain information on a specific page. Like a little information about you for starters.
It’s a indispensable tool if you have a WordPress website. Download the plugin at the WordPress Plugin Directory.
