Customizing the contents of the Page Not Found page in any WordPress theme can be tricky, and usually involes editing the 404.php template file. The Genesis Framework already abstracts the default content of the page into a function, and this plugin can unhook that and replace it with your own custom title and content.
Use [genesis-404-search] shortcode to add a search form to the page.
If you’d like to dynamically list content (ex: most recent posts), I recommend you install the <a href="https://www.wordpress.org/extend/plugins/display-posts-shortcode/" rel="nofollow ugc">Display Posts Shortcode</a> and use it in the 404 page’s content.

Creating widget areas programmatically, then using conditional logic to properly assign them to sidebar locations can be a complex task for a beginner. This plugin allows you to do all this from a simple administration menu, and assign widget areas to sidebar locations with simple drop-down menus within the post/page edit screens, or when editing a tag or category.
