Data disclaimer
Where our data comes from, what it means and what it does not. Last updated 12 November 2026.
Where keywords come from
The keyword generator shows suggestions from YouTube autocomplete, retrieved through our data provider YepAPI. Each keyword is a suggestion that autocomplete returned for one of the queries we asked; we never add keywords of our own.
What we add on top
- Expansion: besides your seed, we may ask about question starters (Standard, 7 lookups), every letter from a to z (A–Z, 27 lookups) and your seed’s top 5 suggestions (Deep, 38 lookups).
- Labels: long-tail means four words or more; question means the keyword starts with a question word or ends with a question mark.
- Relevance: a TubeKeyword estimate from 0 to 100 based on seed word coverage, autocomplete position and the exact seed phrase. It is not a YouTube metric.
What the data does not show
- No search volume, cost per click, keyword difficulty or ranking probability. YouTube does not publish them, and we do not present estimates as official figures.
- Autocomplete from our provider is not specific to a country or language yet. Your country and language choices are stored with each search for video research features.
- Autocomplete changes over time and can differ between people. Results are cached for up to 12 hours, and each search shows when its data was fetched.
- If some lookups fail, we show the rest and say how many are missing.
No guarantees
Keyword research can inform your titles, descriptions and topics, but no tool can guarantee rankings, views or growth. Use the results alongside your own judgement.
