Since my video game https://basketball-gm.com/ targets hard core basketball fans, I post to /r/nba on Reddit in the NBA offseason. In the offseason, there's not much other content to compete against so my posts do well. And the type of people reading /r/nba in the offseason are exactly my target market.
Yep, mostly Google Consumer Surveys, which is a good fit for my audience of dedicated users eager to keep playing (although volume has been down this year, sadly).
