For reaching new people, Instagram says watch time, likes and sends matter most.
Read the guide →Every figure on these pages comes from the network that sets it: Instagram and Meta help centers, TikTok support, YouTube Help, X and Twitch. Each guide links its sources and shows the date we last checked them. When a network does not publish a number, the guide says so instead of guessing.

If you are deciding where to invest your time, the monetization requirements show what each platform asks before it pays creators.
