Using your Nearby scanner

As of the latest version update, the nearby scanner prioritises rarer Pokémon over more common ones. So if you see any of these Pokemon near the top of your list and they’re usually quite common in your area, chances are that it’s a Ditto.

Ask your local community to let you know

Pokémon Go is a very community-based game, which encourages and rewards us for playing in groups. If you aren’t currently playing with a local group, have a search for a Facebook group or attend some raids and ask around. Asking your fellow Trainers to let you know when they find one is one of the best ways to locate a Ditto – hopefully you’ll be around when one finally turns up.
