I know the DM guides in the past say to give bonus xp that parallels low, mid or difficult encounters
Same with traps and skill challenges.
I was thinking of a system where players reward xp to each other. For instance, every player gets a color token. If they feel a player roleplayed something well, they give that player a token. At the end of the session every token you have that is not your color can be cashed in for 5% of your next level
Another idea I had is that all players get the bonus XP (devided between the players) so that way everyone is always at the same level
How do you home brew your bonus xp?
