TikTok

TikTok's algorithm starts every video with a small initial test audience. If completion rate, like rate, and share rate exceed thresholds, the video cascades to progressively larger audiences. Initial distribution is based on content signals (captions, sounds, hashtags) and your account's historical performance. Unlike other platforms, even brand-new accounts with zero followers can reach large audiences quickly through strong content alone.

Optimal length varies by content type. Tutorial and educational content performs well at 60–90 seconds. Entertainment and trend content works best at 15–30 seconds. Deep-dive or storytelling content can reach 2–3 minutes if retention is maintained. The key metric isn't length — it's completion rate. A short video fully watched outperforms a long video with high drop-off every time.

Yes, but primarily for content categorization rather than direct reach amplification. TikTok uses hashtags to understand what your video is about and to serve it to users who engage with similar content. Use 3–5 highly relevant hashtags plus 1–2 broader trend-related ones. Avoid hashtag stuffing — TikTok's algorithm is sophisticated enough to recognize irrelevant tag use.

Low like rates despite decent view counts indicate a content-audience fit problem — viewers are watching but not finding the content resonant enough to engage. Review your past videos and identify which earned the highest like-to-view ratios and what they had in common. Also check whether you're reaching the right audience by reviewing your follower demographics and content category signals.

Going live builds audience relationships and provides a different engagement channel, but doesn't directly boost your regular video distribution. The indirect benefit is that live sessions increase follower activity and interest in your account, which can improve engagement signals on your next post and signal to the algorithm that your account is actively building community.

TikTok's For You Page distributes content to non-followers based on content signals — meaning follower count has limited impact on how widely a video is distributed. Your followers mostly see your content in their Following tab, not the For You Page. This is why a creator with 500 followers can get 1 million views on a single video. Build your content to impress strangers, not just your existing audience.
