š” TikTok Launches New App and Metric, Instagram Tightens Livestream Rules
Big changes are rolling out on both TikTok and Instagram, and they could impact how brands engage across platforms.
1ļøā£ TikTok Pro Goes Live in Europe: TikTok Pro is launching in Germany, Portugal, and soon Spain. Itās a separate app designed to be more curated and ājoyful.ā One standout feature is āSunshine,ā a system that rewards users with virtual currency for engaging with charity content. TikTok converts that into real-world donations. Sunshine is only for users aged 18 and up, and the app mirrors TikTokās main safety features.
2ļøā£ New Retargeting Metric: Engaged Session: TikTok is also testing a new metric called Engaged Session. It tracks users who spend more than 10 seconds on a landing page post-click, allowing advertisers to retarget those visitors. Early results show lower ad costs and stronger engagement quality. Itās a smart shift from basic clicks to meaningful interactions, though it may face hurdles in Europe due to privacy laws.
3ļøā£ Instagram Restricts Live Access: On Instagram, livestreaming is no longer open to everyone. You now need at least 1,000 followers to go live. The change limits access for smaller creators and niche accounts that use Live to build community. Meta hasnāt offered an explanation, but this likely aims to reduce moderation challenges.
The Takeaway
TikTok is leaning into curated experiences and richer engagement signals, while Instagram is locking down live access. For brands and creators, itās a signal to focus on quality engagement, creative experimentation, and hitting platform thresholds that unlock full feature sets.
