Thanks, but I meant more in a tactical/practical sense. What channels do you tend to use to look for those people and contact them?

Depends on the audience, the not-so-technical marketing term for the concept is a "watering hole".

First step is guessing who your customers might be.

Yep, makes sense, have any good illustrative examples? Thanks for the term, though, makes it more googleable.

		Tell me who you think your customers might be? Or ask ChatGPT what's a good watering hole for them, it will definitely come up with some reasonable guesses.
