I find TikTok to be incredibly unpredictable, to the point where I believe no course can guarantee viral success. While such courses may offer some assistance, it's definitely not a surefire method. If any course claims to guarantee viral fame on TikTok, I consider it to be a scam.
Most courses will advise you to focus on improving engagement and retention rates, as well as creating captivating content. However, I'm perplexed when I compare my own experiences. For instance, I have a video with 600,000 views but only a 25% retention rate and a 0.5% engagement rate. Yes, you heard it right - despite the high view count, there are only 2,900 likes and a few comments, saves, and shares. On the other hand, I have a video with only 2,000 views, but it boasts a 66% retention rate and has garnered 490 likes, along with some comments, saves, and shares.
I can't help but wonder how such disparities occur. And I'm just as clueless as you are.
