II. Simulate "Real User Devices" to Avoid Algorithm Warnings TikTok is particularly sensitive to "marketing-oriented operations". In addition to IP, device information can also expose the identity. Logging into an overseas account with a domestic mobile phone, the device model and system version are common in China. Coupled with frequent posting of videos with shopping carts, it's easy to be labeled as a "commercial account" and get shadowbanned. Yajuzhen can replicate the device characteristics of overseas users: install the locally popular iPhone 13 system (not the more common 14 in China) for the Singapore account, and even set the phone font to the "English + Simplified Chinese" mixed display preferred by Singapore users. For the Indonesian account using the Android system, it will carry the customized UI of local brands (such as the unique icons of Samsung Indonesia version). More importantly, the operation traces are "de-regularized". Ordinary operators always post videos at fixed times and reply with unified scripts, which makes TikTok's algorithm think "it's like machine operation". Yajuzhen can set "random intervals" — sometimes post outfit videos in the morning, sometimes unboxing videos in the evening. When replying to comments, use emojis occasionally and Thai slang sometimes, completely like a real user browsing. A beauty blogger was always shadowbanned when posting videos with a regular mobile phone. After switching to Yajuzhen to simulate Malaysian user operations, 3 videos broke through the "500 views" new user pool, and one of them was even pushed to the "Kuala Lumpur Beauty" recommendation page. III. Fit Local Preferences to Make Content "Liked by Algorithms" It's not enough to just avoid shadowban; the content must conform to local user habits. Yajuzhen can help accounts hit the "local traffic password": When posting videos in Thailand, the system will remind that "topics related to the recent Songkran Festival are gaining popularity". After adding the hashtag, the exposure increases by 30%. When posting videos in Malaysia, it automatically adapts to the 16:9 vertical screen ratio commonly used locally (it wasn't noticed during domestic tests that local users rarely use the 4:3 ratio). After the screen is displayed completely, the completion rate increases by 25%. An An's team adjusted the content with this function: they found that Malaysian users prefer "real-person try-on + price marking" (previous pure outfit videos had little interaction). After modification, the like rate increased from 1.2% to 5.8%. There's also a useful "time calibration" function. Indonesian users are used to browsing TikTok from 21:00 to 23:00 (20:00 to 22:00 in China). They used to miss the best posting time. Now the system reminds them according to Jakarta time, and the completion rate of videos within 1 hour after posting has increased from 18% to 53%. With a high completion rate, TikTok will naturally push the video to more people. Now An An's account not only has stable views but also received cooperation from local Thai brands. She often says, "To do overseas TikTok, good content is not enough; you have to make the platform think you are 'one of them'. In the past six months with Yajuzhen, the account has been rooted locally, with stable traffic and smooth monetization — this is the right way to run an overseas account."
