Do you allow comments? If your site has a lot of user interaction, then the reader’s comments end up buried on the last pages or, at the very least, down on the bottom of the post. There’s an easy way to arrange comments so that the most recent are shown first.
And it’s all in the WordPress core.
Navigate to Dashboard >> Settings >> Discussion
Scroll down to ‘Other comment settings‘ and you’ll see where to rearrange the comment order.
