Pages circulation/rotation

Hi all.

Just wanting to see if someone can steer me in the right direction please......  and I apologise as I don't know what it is called what I wanting to do....sorry!

On my landing pages/gallery pages/product pages, for example I have 20 items - I am wanting to have these change position on that specific page layout - for example..... if product#1 was in position number 5 and product#3 was in position 1, if the page were to be refreshed or entered into again, product #1 may show in position 6 and product # 3 in position 4  etc etc.

I have seen on a webpage that each time you went back to the main page it wouldn't keep the same listing sequence - all the listings on that page would swap around with each other.

I am wanting to do this on my page - however, I have no idea how to achieve this.

Help is greatly appreciated.

Thanks 🙂
