Frequently Asked Questions
What is TikTok keyword research?+
TikTok keyword research is the process of finding words and phrases that people actively search for on TikTok's search bar. Unlike hashtags, TikTok keywords are used in video captions, on-screen text, and spoken words — and TikTok's algorithm uses them to rank content in search results. Targeting high-demand keywords helps your videos appear when users search for related topics.
How does TikTok search work in 2026?+
TikTok processed over 140 billion searches in 2025 — making it one of the world's largest search engines. TikTok's algorithm indexes captions, on-screen text, spoken words (via speech recognition), and hashtags. Videos that include searched keywords in these elements rank higher in TikTok search results. 41% of Americans now use TikTok as a primary search engine.
What do High, Medium, and Low demand mean?+
Demand levels are calculated relative to all keyword suggestions returned for your search. High demand keywords appear at the top of TikTok's autocomplete — meaning they're searched most frequently. Medium demand keywords have solid search volume and are good targets with less competition. Low demand keywords are niche but can still drive consistent traffic from a specific audience.
Where should I put TikTok keywords?+
Place keywords in: (1) Your caption — TikTok indexes the first 150 characters especially. (2) On-screen text — TikTok reads text overlays via OCR. (3) Spoken words in your video — TikTok transcribes audio. (4) First comment — TikTok indexes comments too. Avoid keyword stuffing; use 2-3 relevant keywords naturally.
How is this different from hashtag research?+
Hashtags (#dance, #fyp) categorize content and are used for browse discovery. Keywords are what users actively type into the search bar when looking for something specific. Both matter: hashtags help with the For You Page algorithm, while keywords help with TikTok Search rankings. Use TikTapDown's Hashtag Library for hashtag research alongside this keyword tool.
How often is keyword data updated?+
Keyword suggestions are pulled directly from TikTok's live autocomplete engine — the same technology that powers TikTok's search bar. Results are cached for 24 hours to ensure fast response times. Trending keywords (marked with a TRENDING badge) reflect what's surging in searches right now.
