Keywords & hashtags
How to choose TikTok keywords and hashtags that fit your video
Start with the question your video answers. A popular keyword that describes a different subject gives you a weaker brief than a specific phrase that matches the actual demonstration.
Turn a broad topic into a useful question
“Coffee” is a category. “How do I make an iced latte without an espresso machine?” is a question you can answer on camera. Write that question first, then list the objects, steps and outcome that genuinely appear in your video.
For this editorial example, the useful vocabulary might include iced latte, strong brewed coffee, milk and ice. A video about a coffee shop’s interior would need a different set. The two videos share a category, but they do not solve the same problem.
Read popularity and competition as separate signals
Social Expert presents relative keyword indicators. A high popularity label is not an exact number of searches. A low competition label is not a promise that your video will rank. Neither is a prediction of views, followers or sales.
| Question | Decision |
|---|---|
| Does the phrase describe the video? | If no, reject it regardless of its score. |
| Can a viewer see the promised answer? | If no, change the video or choose a more accurate phrase. |
| Is the indicator’s meaning clear? | If no, treat it as uncertain rather than inventing search volume. |
| Do several results have identical scores? | Choose by relevance; the scores do not distinguish those results. |
For a phrase that fits, higher popularity and lower competition may help you prioritize what to investigate. They should not override a mismatch. If a research result for an iced latte tutorial contains an unrelated term about bread, leave that term out. A returned suggestion is a candidate to review, not an instruction to use it.
Build a small vocabulary around one promise
- Write the main question. Use language your intended viewer would recognize.
- Check the footage. Identify where the video actually answers that question.
- Keep the core phrase natural. Your spoken explanation, on-screen text and caption should make sense to a person watching the video. Do not repeat a phrase merely to fill space.
- Add accurate context. An ingredient, technique or audience qualifier can clarify the subject. Do not add an unrelated location or product just because a tool returned it.
- Choose hashtags that describe the post. Use them as useful labels. This guide does not prescribe a magic number of hashtags or claim that a particular count improves distribution.
A worked example
Suppose the footage shows strong brewed coffee poured over ice, followed by milk. A clear opening is “An iced latte-style drink when you don’t have an espresso machine.” That wording also makes the limitation visible rather than pretending the drink was made with espresso.
A possible caption is “My simple coffee-and-milk method for an iced drink at home. Here’s the ratio I used and what I’d change next time.” Candidate labels might be iced coffee, home coffee and coffee recipe. These are illustrative editorial choices, not measured recommendations or claims about current search demand.
If your footage instead tests three espresso machines, start over with that comparison as the question. Reusing the first video’s tags because they scored well would lose the distinction that matters to a viewer.
Use a second source to check the topic
Open TikTok search for this example question to inspect the wording of relevant posts yourself. This is a search link, not a measured result set or endorsement of the videos it returns.
TikTok describes Creator Search Insights as a way to explore topics people search for, with availability depending on region. Use it as another research input where available. Its figures and categories are not interchangeable with Social Expert’s relative indicators.
Keep a simple record: the question, the words you chose, why they fit, the publication date and the results you can observe in your own account. Compare related videos over the same elapsed time. If a post does poorly, do not assume the keyword alone caused it; the opening, demonstration, audience and timing may also differ.
Before you publish
Read the caption aloud without looking at the scores. If it sounds unnatural, simplify it. If a viewer would expect something the video never delivers, rewrite the promise. Useful research should make the post clearer before it makes your keyword list longer.
