HOW to GEO-target??

hii guys wondering if there is any way i can target people or follow them from a particular location.
Also do these strategies if they are can help me to target people on other social media platforms.
I am sorry if my question is pointless.

Target users of a specific hashtag which you know is from that specific place.

You can use
https://twitter.com/search-advanced

which has geo targeting ability and / or finding a bot that does this for you.
