The For You feed is the interface users first see when they open TikTok. It's central to the TikTok experience and where most of our users spend their time exploring the platform.
We make clear to users in our Terms of Service and CGs (and also provide more context in our Help Center
article and Transparency Center
page) that each account holder’s For You feed is based on a personalised recommendation system. The For You feed is curated to each user. Safety is built into our recommendations.
As well as removing harmful misinformation content that violates our CGs, we take steps to avoid recommending certain categories of content that may not be appropriate for a broad audience including general conspiracy theories and unverified information related to an emergency or unfolding event. We may also make some of this content harder to find in search.
Main parameters. The system recommends content by ranking content based on a combination of factors including:
- user interactions (e.g. content users like, share, comment on, and watch in full or skip, as well as accounts of followers that users follow back);
- Content information (e.g. sounds, hashtags, number of views, and the country the content was published); and
- User information (e.g. device settings, language preferences, location, time zone and day, and device types).
The main parameters help us make predictions on the content users are likely to be interested in. Different factors can play a larger or smaller role in what’s recommended, and the importance – or weighting – of a factor can change over time. For many users, the time spent watching a specific video is generally weighted more heavily than other factors. These predictions are also influenced by the interactions of other people on TikTok who appear to have similar interests. For example, if a user likes videos 1, 2, and 3 and a second user likes videos 1, 2, 3, 4 and 5, the recommendation system may predict that the first user will also like videos 4 and 5.
Users can also access the “Why this video” feature, which allows them to see with any particular video that appears in their For You feed factors that influenced why it appeared in their feed. This feature provides added transparency in relation to how our ranking system works and empowers our users to better understand why a particular video has been recommended to them. The feature essentially explains to users how past interactions on the platform have impacted the video they have been recommended. For further information, see our
newsroom post.
User preferences. Together with the safeguards we build into our platform by design, we also empower our users to customise their experience to their preferences and comfort.
These include a number of features to help shape the content they see. For example, in the For You feed:
- Users can click on any video and select “not interested” to indicate that they do not want to see similar content.
- Users are able to automatically filter out specific words or hashtags from the content recommended to them(see here).
Users are able to
refresh their For You feed if they no longer feel like recommendations are relevant to them or are too similar. When the For You feed is refreshed, users view a number of new videos which include popular videos (e.g., they have a high view count or a high like rate). Their interaction with these new videos will inform future recommendations.
As part of our obligations under the DSA (Article 38), we introduced non-personalized feeds on our platform, which provide our European users with an alternative to recommender systems. They are able to turn off personalisation so that feeds show non-personalised content. For example, the For You feed, will instead show popular videos in their regions and internationally. See
