Question: what is xp for in pokemon go?
Answer: Catching a new Pokémon gives you 100 XP. Evolving Pokémon gives you 500 XP. When you have the Lucky Egg in play, you'll gain 200 XP for any new captures and 1,000 XP for any evolution. If you have a lot of Pokémon to evolve wait to do it until you have a Lucky Egg.
