    How the TikTok algorithm works - Explained by the CEO

    The recommendation algorithm on TikTok is essentially a mathematical process that uses AI and machine learning to understand users' preferences and show them relevant content. In a nutshell, if you liked videos one, two, three, and four, and another user liked videos one, two, three, and five, the algorithm may suggest video six to both of you based on your shared interest in videos one, two, and three. This process is carried out in real time across a vast user base, allowing the platform to quickly learn users' interests and provide them with content that aligns with their preferences. Unlike traditional methods of explicitly asking users about their interests, TikTok's algorithm observes users' interactions with content (such as likes, shares, and views) to gauge their preferences and tailor their feed accordingly.
