This reads more like a sign saying "over x customers served" on a fast food restaurant. It doesn't really matter, nobody will ever care about the accuracy of the information, but it's a pride thing and makes a point about the establishment.
Obviously there aren't millions of meaningful hits on most terms, but you don't need to go to page 10001 for that. You can get to page 3 and know it for sure.

This does call back to the odd false confidence that our industry bakes into the interview process. "Design a realtime chat program that can notify any number of followers that you posted and let them respond with sub millisecond latency."
I can’t push a single key in less than 20ms latency. Those poor interviewees are building Twitter but for bots. Unfortunately, that is probably a relevant skill…
