It is recommended that long articles are split into multiple pages. This will reduce your bounce rate and of course – create more page views for your website. On most reliable WordPress themes, you just have to paste this code: <!––nextpage––> wherever you want the next page to start. This will make the pagination to appear at the bottom of the article content. One thing we have to mention though is that you need to be in “Text view|, not in the “Visual view” of your post editor.
As we mentioned earlier, this should work fine with most reliable and well-coded WordPress themes, but there are some bad examples. If you have added the <!––nextpage––> shortcode and your pagination is not shown – it’s because the theme developer forgot to add a line of code in the theme source code.
Solving this issue is not hard, all you have to do is to edit the theme single.php file and find the line where the_content(); function is called. We recommend adding the <?php wp_link_pages(); ?> right after that function is called, so the pagination will be added right after the content from your post editor.
After adding the code, your post pagination should start working. If you are a technical person, you can even play with the function and add some parameters and even style it. You can find more information about this in the WordPress Codex.
