Sometimes you may have a blog that you’ve worked on for a while, but you want to start over. If you’d like a clean slate, you have three options.
Emptying your site: the DIY method
If you want a fresh start on your WordPress.com site, you can delete all of your content from your site and still keep your current WordPress.com address (such as
yourgroovysite.wordpress.com). Here’s how to do it:
Emptying your site: The automated option
If you have a lot of content, you can ask the WordPress.com support team to empty your site for you. Emptying a site removes all posts, pages, uploaded media, tags, and categories permanently from your site so you can reuse the site address. If we empty your site, your theme and any customizations you’ve made remain in place, and if you have a custom menu, any links to external sites will be preserved; other menu items will be deleted.
Note: emptying a site is not reversible!
Create a new blog
Your third option is to create a brand new blog, with a new WordPress.com address, under your existing WordPress.com account. There is no limit on how many blogs a user can have on WordPress.com.
