KFC's website chewing me out about using an adblocker
If small mom and pop websites ran by starving artists cannot shame me into turning it off to see their factor75 banner what makes you think I will do it for you?
It's for remarketing which is a part of marketing intended to engage audiences who have already interacted with a brand but didn't convert into a sale at the time they interacted. The idea is that you know they're interested but need to remind them at a later time or they'll forget about it. The main example used for this is when customers hop on a site, add things to their basket, but then leave without purchasing... You know they were interested but something resulted in them backing off at the last minute, a reminder later on results in sales.
I use to work there and it comes up in convos time to time. I like to see what promos are going on. I would never eat at the place imho. Too many nightmares.
