Method 1. Split WordPress Posts without a Plugin
The easiest way of setting up post pagination is by using the ‘Page Break’ block in your WordPress content editor. You don’t need a WordPress plugin to break up your articles into multiple pages.
First, edit or add a new post on your WordPress website. After that, click the plus (+) button where you want to split your content and add a ‘Page Break’ block.
You should now see a page break line in your content to indicate where the pagination will appear.
If you are using the classic editor, then use the <!––nextpage––> tag to split your content.
Just edit any blog post and go to the ‘Text’ view to enter the tag where you would like to split the content.
You can also use the Alt + Shift + P keys on your keyboard to insert page breaks. To do that, go to the ‘Visual’ view and press the keyboard shortcut keys where you would want to add a page break.
