The archive pages in Genesis can be a bit confusing. Other than the URL (and breadcrumbs if you have them turned on), they look exactly the same as the main blog.
Genesis provides a useful feature for adding headlines and intro text to the top of your archive pages. Go to Posts > Categories and edit a category to see the screenshot above. But this requires you to manually type it in for each category. If you have a lot of categories this can be a hassle.
Add this code to your theme’s functions.php to automatically default that field to your category name. If you provide an “Archive Headline” when editing a category, that is used. But if you don’t, the category name is used.
This applies to categories, tags, and any custom taxonomies you’ve created.
