The TikTok algorithm didn’t change overnight: it was adjusted in layers throughout 2025 and consolidated in 2026 into a model where initial retention weighs more than followers. If you’re coming from old guides based on hashtags and posting times, you’re late. This checklist is designed to audit your account point by point, without promises of virality.
Checklist of signals the system evaluates today
1. Retention in the first few seconds
Check whether your video exceeds the full-view threshold relative to its length. According to TikTok’s official documentation, the model first distributes to a small group and expands if retention exceeds the average for the format. A 12-second clip with 70% retention performs better than a 45-second one with 30%. Check the retention graph in Analytics and pinpoint the exact second where the curve drops.
2. Rewatches and direct message shares
Rewatches (watching again) and DM sends are signals of perceived value that the system weighs above likes. Check whether your videos have natural loops: an ending that invites replaying without sounding forced. If the share percentage is below 1% of views, the content informs but doesn’t connect.
3. Originality versus recycled content
Since the 2025 adjustments, the algorithm reduces distribution of material reposted from other platforms with visible watermarks. Remove third-party logos, avoid uploading the same video to Reels and TikTok without adapting the framing and audio. This doesn’t work for those managing multi-purpose accounts: you’ll need to record natively in vertical or reframe with real editing.
4. Match between audio, on-screen text, and topic
The system transcribes the audio and overlaid text to classify the video. If you talk about baking but the text says “fitness recipe,” the classification gets diluted and distribution slows down. A practical check: read only the on-screen text and ask yourself if it describes the content unambiguously.
5. Niche consistency in the last 20 videos
Review your last twenty posts. If more than 30% fall outside your main topic, the profile loses classification clarity. On small accounts this is more noticeable than on large ones, which already have a consolidated audience. It’s the most uncomfortable limitation: posting off-niche trends can give you a spike in views while simultaneously cooling the distribution of your regular content for days.
6. Comments with creator replies
Replying to comments in the first hour isn’t a forum myth: it generates secondary conversation that the system interprets as interest. Check this box only if you reply with content, not with lone emojis.
7. Frequency and posting window
The exact time matters less than consistency. If you post three times a week in different slots, the system takes longer to identify your audience. Choose two slots and keep them for at least three weeks before evaluating results. Be wary of “best hours” data: it’s usually based on large accounts with global audiences.
8. Signs of spam or aggressive editing
Text covering more than 30% of the screen, sustained all-caps, promises of easy money, or external links in the first comment can reduce reach. Check whether any recent video has abnormally low views compared to your average: review the text and audio before blaming the algorithm.
What the algorithm doesn’t control (and you should accept)
No one outside TikTok knows the exact weights of each signal. Any table with specific percentages is speculation. There’s also no button to “reset” an account’s distribution: adjustments show up over weeks, not hours. And if your content depends on commercial music, licensing availability varies by country and can affect playback outside the app.
Monthly audit routine
Once a month, review these five points in Analytics: average retention by format, share percentage, traffic sources (“For You” versus followers), videos with atypical performance, and net follower growth. With that data you adjust the next cycle. If two metrics worsen at the same time, change only one variable: the format or the hook, never both.
