Twitch Growth Streaming Planner

Based on the information provided, I would suggest the following strategy and schedule to help grow your Twitch channel:
Schedule - Stick to your preferred streaming days of Tuesday, Thursday, and Saturday. To accommodate your target audience spread across the US and Europe, consider starting your streams at 1 PM Eastern Standard Time (EST). This allows you to catch the afternoon crowd in the US and the evening crowd in Europe.
Duration - Continue with your typical stream duration of 3 hours. However, if possible, consider occasionally extending your stream during game releases or special events. Longer streams could help retain viewers who might join at different times.
Content Focus - As your audience enjoys game strategy discussions and your humor, build segments into your stream that cater to these preferences. For example, you could dedicate the first 15 minutes to discussing strategies for the game you're playing. Also, make humor a significant part of your streaming style.
Game Selection - Capitalize on your focus games - the Battlefield series and Witcher series. Keep up with news, updates, and popular mods in these games to offer your viewers valuable content. Align your streaming schedule with major game updates or releases, which could attract new viewers.
Viewer Engagement - Encourage viewer interaction to keep them engaged. Organize weekly contests or challenges, Q&A sessions about gaming strategies, and viewer polls about in-game decisions. Also, recognize loyal viewers and followers to make them feel appreciated.
Other Content - For the 30% of your time dedicated to other content creation, consider developing YouTube content that complements your Twitch streams. You could make condensed strategy guides, humorous gaming moments compilations, or detailed reviews of game updates. Use these videos to promote your Twitch streams.
Goals - To monitor your goal of increasing follower growth by 30%, use Twitch's analytics tools. Keep track of your most popular content, viewer engagement, and follow/unfollow trends to understand what works best.
Remember, consistency is key. Regular streaming according to this plan will help build a loyal viewer base and attract new followers. Make sure to regularly interact with your viewers, both on and off stream, and continuously adapt your content strategy based on viewer feedback and trends.
