Step Two: Data Collection
After its analyses and verifications, the content will be sent to a small audience group and, a valuation will take place based on how the sample of users reacted to this content. Each metric monitored has a possible associated score. TikTok makes its predictions to be able to boost your content to users and make recommendations on the #ForYou page.
Step Three: Performance Assessment
Transmitting your video to a representative sample of your audience allows the algorithm to Calculate different rates and metrics. This is called the “rating ratio.” Like a school test, the TikTok algorithm scores your content out of 30 points:
Review rate = 10 points (this is the rewatch rate)
Completion rate = 8 points (What percentage of the video has been watched. For example, if they watched half of the video, the ratio is 0.5. Good video content will be watched in its entirety. TikTok shows the video's analytics and the user can see, on average, how many seconds viewers watched compared to the length of the video. If the average is greater than the length, the video has been viewed multiple times, which favors the ratio.)
Shares (when viewers share a video with other users) = 6 points. Shares indeed allow your video to win new viewers and commitment.
Comments = 4 points (The more comments the better. If the comments include other tagged users, it will direct more users to the video, similar to sharing.)
I like = 2 points (It's the smallest commitment, but it counts.)

On the other hand, if the score is lower than the average, your video will disappear into the abyss.
If your content doesn't go viral in the first few days, don't give up. The cycle doesn't end, it just stops. This means that the algorithm could go back to your content once you start posting more frequently on the platform.
