Days 61-90 are optimization and scaling phase. The growth engine is running. Now you tune it and decide what to invest in next.

1. First giveaway test. Run one scheduled giveaway during this window. Measure the follower spike, the chat engagement during announcement and draw, and the 30-day retention of new followers from the giveaway cohort. This tells you if giveaways are worth the cadence.
2. Analytics review. Pull data from Twitch dashboard, YouTube Studio, TikTok Creator Analytics. Identify the top 10 clips by performance. Identify the single highest-CCV stream of the past 90 days. Reverse-engineer what made each work.
3. Scaling decisions. Based on the data, decide where to invest week 13+. Options: add a 4th stream day, double clip output, run paid ads to amplify proven clips, expand to a second platform. Pick one. Do not pick all.

By day 90, the channel should be on a clear growth trajectory. If you are below 100 followers at this point, the issue is content-market fit (wrong niche or weak hook patterns), not effort. Audit, adjust, and run the next 90 days with the corrections.
