TikTok hashtag strategy that actually works

Last updated August 6, 2026 · Written by the Growently Team

Quick answer: Use 3–5 hashtags per post: 2–3 niche tags that describe exactly what's in the video, 1–2 topic tags with medium reach, and at most one broad tag. Hashtags are classification signals that help TikTok pick your test pool — not magic reach buttons.

What hashtags actually do on TikTok

Hashtags help TikTok classify your video so it lands in front of the right interest pool. They are one input among many (visuals, audio, caption text, and on-screen text are also read). They don't multiply reach — they aim it. A perfectly aimed test pool that watches to the end is worth more than any tag.

The 3–5 tag formula

2–3 niche tags — specific to the content: #airfryerrecipes, #torontorealestate, #guitarlessons. These do the aiming.
1–2 topic tags — the broader category: #cooking, #realestate, #musician.
0–1 broad tag — #fyp and friends. Harmless, near-useless: hundreds of millions of posts use them, so they classify nothing.

Common hashtag mistakes

Tag stuffing. Fifteen hashtags dilute the classification signal and read as spam to humans.
Chasing unrelated trending tags. Landing in the wrong test pool means low completion → distribution stops. Precisely the outcome you don't want.
Copy-pasting one tag block everywhere. Different videos are about different things; tags should change with content.
Believing banned-hashtag folklore. If reach dropped, look at your recent completion rates before blaming a tag.

The first-comment trick

Many creators keep captions clean and human, then put hashtags in the video's first comment — classification still works, aesthetics improve. Growently schedules the first comment automatically alongside the post, and its hashtag tool builds a suggestion set from your caption's actual keywords (labeled honestly — smart suggestions, not live trend data).

Frequently asked questions

How many hashtags should I use on TikTok?

3–5. Enough to classify the content precisely, few enough that each carries signal. More than that dilutes rather than multiplies.

Does #fyp actually work?

Mostly no. It's used on a huge share of all posts, so it provides almost no classification signal. It doesn't hurt — it just doesn't do what people hope.

Should hashtags go in the caption or first comment?

Both work for classification. First-comment placement keeps captions clean; Growently can schedule the first comment automatically with the post.
