This is very close to home (sadly). Someone I worked with recently put the "X of these sold in the last 24 hours" across a load of product pages as an example of "things we should be doing to increase conversion." It didn't increase conversion because the target market was all wrong (I suspect it might, for a single click from FB/native ad to a single landing page for an 'on a whim' product). More so, much like this example, it refreshed every time you reloaded the page. If you went back to the product it was a different number. If you HAVE to do this, at least use a cookie or something. The changing number makes the product, and by extension the whole site, look completely suspicious. One of the absolute number one things I want to do on a landing page/PDP is build trust. This falls at the first hurdle. This wasn't implemented in the UK, but with a little Googling I ended up under the impression it would break trading laws over here.
