I am planning to make a job offer website. But what do you do when the job offer expires. Do you put it in an archive category and show the active ones below on that page or do you remove it? When you remove it you will get a 404. And when you keep it archived your internal linking will stay.
If it’s still interesting for your users to find expired job offers you leave the page as is. But you’ll end up with many pages on your platform. After a while (ie. month after expiry) If don’t see how an expired job would still be relevant in which case I’d put a 301 to its job category page or another page that’d relevant for someone ending up on an old expired job.
