Key Ranking Factors

The algorithm prioritizes three main factors: user interactions, video information, and device/account settings. These elements help TikTok tailor content to individual preferences.

User Interactions

Likes, shares, comments, watch time, and follows influence recommendations. Engaging more with specific content signals interest, making similar videos appear more frequently.

Video Information

Captions, hashtags, sounds, and descriptions play a role in discovery. The algorithm matches this metadata with user interests to surface relevant videos.

Watch Time & Completion Rate

TikTok favors videos that keep users engaged. Longer watch time and full video completions indicate quality, increasing the chances of being recommended.

Engagement Metrics

High engagement rates, including shares and duets, boost video reach. Videos that spark reactions and participation are more likely to trend.

Content Trends & Virality

Trending sounds, hashtags, and challenges gain higher visibility. Using popular trends increases the likelihood of a video appearing on more feeds.

New vs. Established Creators

The algorithm gives new creators a chance by testing their content with a small audience first. Performance metrics, such as watch time and interactions, determine its further reach.

Relevance Over Follower Count

Unlike other platforms, TikTok recommends content based on interest, not followers. Even small accounts can go viral if their content resonates.

Personalized Feed

Every "For You" page is unique, adapting to changes in user preferences. The more users engage, the more refined their recommendations become.

Restrictions & Filters

TikTok limits duplicate content, low-quality videos, and rule violations. Content that doesn’t meet community guidelines may be suppressed.
