I have been curious to know which plugin is used to automatically update posts in wordpress. I noticed that some sites like justnaija.com and so on will make a post that is over 24 hours old when you search on Google and maybe in the next hour if you search for the same keyword, the post still shows with a different publishing time which is earlier than the one you saw hours ago. I believe they don't do this manually so I really wish to know the plugin used for this. I've searched and reached out to some of them but they refused to tell me. I believe if I can't find it here, then I can't find the answer anywhere else. Thanks guys.
