To ensure that your site isn’t losing any performance from a huge backlog of draft pages and posts, you should go through and delete any unnecessary drafts. Who knows, maybe you’ll even find a draft that you have a new urge to finish while you’re sifting through the trash.
Follow the steps in this tutorial to delete unneeded page and post drafts in WordPress.
Deleting Page and Post Drafts in WordPress
The process is the exact same whether you’re deleting page or posts drafts. The only difference is which option in the sidebar that you pick in Step 1.
Step 1: On the sidebar, select All Pages or All Posts.
Step 2: Select the Drafts option above the pages/posts.
Step 3: Click the checkbox next to any page/post drafts that you’d like to delete.
Step 4: In the Bulk Actions dropdown box, select Move to Trash.
Step 5: Click Apply.
Step 6: Select the Trash option above the pages/posts.
Step 7: Repeat the above process, but now select Delete Permanently in the dropdown box. Then, select Apply. Be careful, though, because there’s no way to get this page or post back after this step.
