Basically it's like count. Maybe they get a little more sophisticated and filter out spammy likes from that number. Without Instagram supporting links on posts, it's about the best you can do. Some accounts also change their bio URL to whatever their sponsor wants for 24 hours etc and say "click my bio link for more". Obviously that's more trackable.
