Why is UCF not ranked higher globally?

Hey guys, I was checking out universities in Florida and came across the University of Central Florida. But when I looked up the university of florida ranking in the world, UCF didn’t rank as high as I expected. Any idea why it’s lower in the QS rankings?

Yeah, I noticed that too. UCF has a huge student population and good programs, but its global rank is kinda mid. Maybe it’s because of research output?
