FWIW, I’ve found that on Lichess I’m rated at least 100 points higher than what I would be on Chess.com (the most popular chess site), and maybe 150 points higher than what I’m rated by the US chess federation, which mainly rates live, not online, games.
A player with a rating of 2000 by the US federation would be called an “expert”, just below the 2200 rating that earns you the title of “master”.
