I remember seeing something that showed the number of users at the bottom-left for eCommerce websites, which was meant to increase urgency and conversion rates for the pages. But, I can't seem to remember what it was called.
It might have been Proof ? Shows recent purchases and such.
That's exactly what I was thinking of, thanks!
It’s such a coincidence, I wanted to validate a product idea for the same thing, you could see that post in my profile.
