How to Change WordPress Permalinks for Split Posts

1. Sign in to WordPress. Choose the 'All Posts' link from the 'Posts' pane on the left side of the WordPress Dashboard.
2. Scroll through posts until you locate the one whose permalink you want to edit. Select the 'Edit' button below the post's name.

3. Click the 'Edit' button next to the permalink. Input any title you desired for the post, keeping in mind that you don't need to specify 'Page 1' or 'Page 2' -- WordPress does this automatically for your readers. Select 'Update' to update the entry to reflect the new permalink.
