# Do Hashtags Work on TikTok? Only +3.7% (1,569 Videos) (https://www.socialcrawl.dev/blog/do-hashtags-work-on-tiktok)
> Hashtag use lifts TikTok views ~3.7% over an account's own median, ~9.5% with heavy tagging, ~16.7% with #fyp — from 1,569 videos, 40 accounts (2026-08-10).
Do hashtags work on TikTok? We measured 1,569 TikTok videos from 40 public accounts, pulled 2026-08-10. Using any hashtags at all is worth about a 3.7% lift over a video's own account baseline; going heavy, seven or more tags, is worth about 9.5%. Real, positive, and a lot smaller than most TikTok hashtag advice implies.
Every number in this post compares a video only to that same account's own median video, not to other accounts. That's the whole reason the effect looks modest instead of dramatic — the method is explained in full further down, and it's the part that matters most if you want to trust any of this.
Here's what you're up against on this exact search: the [#1 Google result for "do hashtags work on tiktok"](https://www.reddit.com/r/socialmedia/comments/1da7paj/why_do_lots_of_creators_on_tiktok_not_use/) is a Reddit thread from June 2024 with four upvotes, four replies, and no body text at all — just a ten-word question, posted by an account that has since been deleted. Google ranks that above every professional guide written on the subject, which says plenty about how little measured evidence exists on this topic.
**A 2026 study of 1,569 TikTok videos across 40 public accounts found that hashtag use raises a video's views by roughly 3.7% relative to that account's own median, rising to about 9.5% for videos carrying seven or more hashtags.**
## Do Hashtags Work on TikTok? The Measured Effect
Yes, but barely: the median normalized view score climbs from 0.975 with no hashtags to 1.069 with seven or more — a real, modest, positive drift.
| Hashtag count | n videos | Median normalized score |
| --- | --- | --- |
| 0 | 570 | 0.975 |
| 1-3 | 265 | 0.967 |
| 4-6 | 504 | 1.004 |
| 7+ | 230 | 1.069 |
*Medians are shown to three decimals; the percentage differences quoted in the text are computed from the unrounded values in the underlying evidence file, not from these rounded cells.*
All four buckets clear n≥30, so none of this needs a thin-sample caveat.
"Normalized score" means each video's view count divided by that account's own median view count. An account's typical video scores 1.0; a video that did 20% better than that account's norm scores 1.2. It's the only way to compare a mega-account's video against a mid-tier account's video without the comparison being dominated by follower count — more on why that matters in the next section.
| Group | n | Median normalized score |
| --- | --- | --- |
| Any hashtags (1+) | 999 | 1.012 |
| No hashtags | 570 | 0.975 |
That's roughly a 3.7% relative difference — directionally positive, but nowhere near "essential." Plenty of top-tier accounts post hashtag-free and do just fine relative to their own baseline.
The apparent edge in the 7+ bucket is concentrated in a handful of habitual heavy-taggers: five accounts contribute about 46% of that bucket's 230 videos. That describes those five accounts' posting pattern, not a universal law about what happens if you personally add more tags.
Hashtags have a small, real, positive association with view performance on
TikTok — about +3.7% for using any at all, +9.5% for using seven or more —
once you control for account size. That's a fraction of the "hashtags 10x
your views" claims circulating in TikTok advice, and it's concentrated in
mid-tier accounts rather than the mega accounts that dominate raw view
counts.
## Why the Raw Numbers Say Hashtags Hurt You (They Don't)
Look at the same 1,569 videos without controlling for anything, and you'd draw the opposite conclusion. In raw, unnormalized terms, zero-hashtag videos in this sample pulled a median 1,077,104 views; videos with seven or more hashtags pulled a median 14,736. That's 73 times more views for skipping hashtags entirely — exactly the kind of "gotcha" number that ends up in a screenshot with a red arrow on it.
It's also measuring the wrong thing. Mega-tier creators, the kind with tens of millions of followers, mostly post with zero hashtags. Mid-tier niche accounts post with hashtags on nearly every video. A raw comparison of "hashtag videos vs. no-hashtag videos" is mostly a comparison of account size, dressed up as a comparison of hashtag strategy:
| Pattern | Example accounts |
| --- | --- |
| 0% of videos use any hashtag | mkbhd (macro, tech review), nasdaily (macro, storytelling) |
| Under 10% | bellapoarch, kyliejenner, photographer8.0.4, charlidamelio |
| 90-100% | 15 of the 24 mid-tier niche accounts in the sample (finance, cooking, fitness, dog training, study-with-me, travel) |
Hashtag usage tracks account category and tier far more tightly than it tracks any view outcome — which is exactly why the raw numbers above are so misleading.
The fix is within-account normalization: divide each video's views by that same account's own median views, so a video is only ever compared to its own account's typical video, never to a different account's. That's what produces the 0.975-to-1.069 range in the section above — [the same account-size confound we control for in our TikTok engagement rate benchmarks](/blog/social-media-engagement-rate-benchmarks-2026).
TikTok has effectively said as much itself. In a [November 2023 Newsroom post](https://newsroom.tiktok.com/en-us/the-truth-about-tiktok-hashtags-and-content-during-the-israel-hamas-war), the company wrote that "the number of videos associated with a hashtag, alone, do not provide sufficient context." That's TikTok's own explanation for why raw hashtag aggregates mislead, and it's the closest thing to an official endorsement of the approach this study takes.
## How Many Hashtags Should You Use on TikTok?
The measured data shows no single optimal hashtag count: performance drifts gradually upward from a median 0.975 with no hashtags to 1.069 with seven or more, without a sharp peak at any specific number in between.
| Hashtags used | n videos | Median normalized score | vs. 0-hashtag baseline |
| --- | --- | --- | --- |
| 0 | 570 | 0.975 | — |
| 1-3 | 265 | 0.967 | −0.8% |
| 4-6 | 504 | 1.004 | +3.0% |
| 7+ | 230 | 1.069 | +9.6% |
If you're looking for "the" right number, this table is the honest answer: there isn't one. The curve is a shallow, mostly upward drift, not a peak-and-drop-off — going from 4-6 to 7+ helps about as much as going from zero to 4-6 did.
## The "3-5 Hashtags" Rule No One Can Source
Three of the top six results for this exact search — [Juicer](https://www.juicer.io/blog/tiktok-hashtag-mistakes), [Sprout Social](https://sproutsocial.com/insights/tiktok-hashtags/), and [Legiit](https://legiit.com/blog/importance-of-hashtags-on-tiktok) — all recommend using 3 to 5 hashtags per TikTok post. None of the three cites a source for that number.
Juicer's justification is that TikTok has "a caption limit of 100 characters for hashtags," which is false: TikTok's caption limit is 2,200 characters, with no separate hashtag sub-limit. Sprout attributes its number to "data from CapCut" — but the CapCut page it links to contains zero occurrences of the words "study," "sample," "dataset," or "analyzed." It's a bare marketing-page assertion, not data. Sprout also contradicts its own headline 14 lines later on the same page, recommending a "3-3-3" strategy that adds up to nine hashtags total.
Here's what our own data says about that consensus number: the 4-6 bucket, right where "3-5" lands, measured a median normalized score of 1.004 — essentially zero measurable lift over an account's own baseline. The industry's single most-repeated hashtag recommendation sits on the one bucket with no discernible effect in this dataset.
The phrases "3 hashtag rule" and "5 hashtag rule" — which people search for by name — appear zero times across all four competitor articles we checked. Nobody has actually named or sourced either "rule." We answer both directly in the FAQ below.
## Does the #FYP Hashtag Work on TikTok?
This is the biggest number in the whole dataset, and also the one that needs the most caveats.
| Group | n | Median normalized score |
| --- | --- | --- |
| `#fyp` present | 156 | 1.153 |
| `#fyp` absent | 1,413 | 0.988 |
| fyp-family present (`#fyp`/`#foryou`/`#foryoupage`/`#viral`) | 168 | 1.197 |
| fyp-family absent | 1,401 | 0.985 |
Videos tagged `#fyp` scored about 16.7% higher than their own account's median; broadening to the whole "discovery hashtag" family widens that to about 21.5%. Both comparisons clear the n≥30 bar comfortably, and it's the largest single effect anywhere in this study — bigger than hashtag count, bigger than anything else we measured.
It's also the effect most likely to be a selection effect rather than a causal one. Creators may add `#fyp` preferentially to videos they already expect to do well, for reasons that have nothing to do with the tag itself. This data can't rule that out. Treat it as a real, correlational finding, not "add #fyp and your views go up."
The claim that "TikTok confirmed #fyp doesn't affect distribution" circulates constantly. It has no primary source: TikTok has never said anything about #fyp, positive or negative, in Newsroom, the Transparency Center, TikTok For Business, or Creator Academy. We checked all four.
The only actual #fyp experiment cited anywhere on this search's results page is a single small-account test, run by Hootsuite, that its own author described as "so negligible I don't think we can draw any conclusions." The link to it now [301-redirects to an unrelated "best hashtag tools" listicle](https://blog.hootsuite.com/hashtag-analytics/). That's the entire empirical base the "#fyp does nothing" consensus rests on — and it's now a dead link.
### #foryoupage Has Vanished From Real Captions
`#foryoupage` appears zero times across all 1,569 captions in this sample — not once, across 40 accounts and six years of posting history. That's despite the tag still showing up in current "best TikTok hashtags" listicles. As a real creator habit in 2026, `#foryoupage` looks functionally extinct. If you're going to use a discovery tag at all, the data says `#fyp` is the one still actually in circulation.
## Does Anyone Else's Data Agree With Ours?
It does, and that agreement is the strongest thing we can say for this study. [Metricool published a 2026 study](https://metricool.com/press-release-tiktok-study-2026/) of 2,314,756 TikTok posts across more than 92,000 accounts (2026-05-12) and found that posts with at least one hashtag get nearly 5% more views and more than 9% more interactions than posts without.
Our own headline number — a 3.7% lift for using any hashtags versus none — lands in that same small-positive range, on a sample about 1,500 times smaller, pulled independently, using a completely different method: within-account normalization here, versus Metricool's aggregate before/after comparison. Two measurements at wildly different scales landing in the same place is a better argument than either one alone. It refutes both "hashtags do nothing" and "hashtags will 10x your views."
One thing nobody else publishes: a hashtag-count curve for TikTok specifically. [Socialinsider's often-cited "hashtag count doesn't matter" finding](https://socialmediatoday.com/news/new-report-highlights-that-instagram-hashtags-dont-significantly-increase/622260/) is about Instagram, not TikTok. [Rival IQ reports TikTok hashtag usage rates](https://rivaliq.com/blog/tiktok-benchmark-report/), not a performance curve. The 0.975-to-1.069 shape in this study appears to be uncontested ground.
## Why TikTok's Own Hashtag Advice Is Six Years Old
TikTok's own explanation of how its recommendation system works — the closest thing to an official source on any of this — is [datelined June 18, 2020](https://newsroom.tiktok.com/en-us/how-tiktok-recommends-videos-for-you), and has never been replaced. Every "how the TikTok algorithm works in 2026" post you've read is paraphrasing a six-year-old document.
Here's the load-bearing part, verbatim: recommendations are based on "user interactions," "video information, which might include details like captions, sounds, and hashtags," and "device and account settings." Hashtags appear exactly once, third in a three-item bundle, with no weight assigned and no recommended count — ever, from TikTok, in six years.
The advice built on top of that document has also gone stale in a more concrete way. TikTok [removed public hashtag view counts in February 2024](https://counterhate.com/research/tiktok-removes-views-from-hashtags/) and [narrowed Creative Center's hashtag search to a top-100 list by industry in January 2024](https://socialmediatoday.com/news/tiktok-implements-restrictions-hashtag-search-creative-center/703956/). The old "find a hashtag with 2.3 billion views and ride it" playbook, still taught in current listicles, is now literally unexecutable — TikTok withdrew the data it depended on two years ago, and nobody updated the advice.
## What Hashtags Should You Actually Use on TikTok to Go Viral?
Everything above adds up to a short, honest list — no new claims here, just what the measured numbers actually support:
- **Use some hashtags.** It's worth doing: a small, real +3.7% edge over using none at all.
- **Don't obsess over the exact count.** The 4-6 range, where most advice tells you to land, measured no lift at all (1.004).
- **`#fyp` is the one lever with a real measured edge** (+16.7%), but it's correlational — treat it as reasonable to include, not a growth hack.
- **Skip `#foryoupage`.** It's not just weak, it's functionally extinct: zero uses in 1,569 real 2026 captions.
- **Heavy tagging (seven or more) only showed an edge in accounts that already do it habitually.** There's no evidence it helps an account that isn't already in that pattern.
- **Hashtags are a minor lever.** Account maturity and content category drive far more of the variance in this dataset than hashtag count does, and [how often you post matters at least as much as which hashtags you use](/blog/how-often-should-you-post-on-tiktok).
If you only take one thing from this post: hashtags are worth a few minutes of thought per video, not a strategy meeting.
## How We Measured This — and How You Can Reproduce It
**Sample:** 40 public TikTok accounts — 12 mega (10M+ followers, hand-picked well-known creators), 4 macro (1M-10M), and 24 mid-tier accounts (mostly 30k-830k followers) discovered live via 12 niche `search/users` queries across categories like personal finance, home cooking, fitness, and study-with-me. That produced 1,572 raw videos, deduplicated to 1,569 after removing three cursor-boundary repeats. Pulled 2026-08-10 (UTC).
**Formula:** `normalized_score = video.views / account_median_views`, bucketed by counting `#(\w+)` matches in the caption (0, 1-3, 4-6, 7+). `#fyp` and the fyp-family were checked with the same case-insensitive regex and compared the same way.
**Endpoints:** three calls, all documented, all reproducible with any SocialCrawl API key — `GET /v1/tiktok/profile` for follower verification, `GET /v1/tiktok/search/users` for niche account discovery, and `GET /v1/tiktok/profile/videos?handle={handle}&sort_by=latest`, paginated, for the actual video capture. Total cost: 228 credits.
That's the whole method. No proprietary tooling, no black box. Pick a set of accounts, pull their recent videos, regex the captions, divide each video's views by that account's own median, and bucket the results. [If you want to pull TikTok data like this yourself](/blog/how-to-scrape-tiktok-2026), the same three endpoints are all you need.
### What This Data Can't Tell You
This is observational, not causal. We can't separate "hashtags cause more views" from "creators whose content already performs differently also happen to have different hashtag habits" — that's true of the bucket findings, and especially true of the `#fyp` result. The 40 accounts are also not a random sample of TikTok: mega and macro accounts were hand-picked well-known names, and mid-tier accounts were surfaced by TikTok's own search for topical queries, which favors accounts already sized to be found. View counts are a snapshot on the pull date, and while normalizing by account controls for account size, it only partially controls for a video's individual age — older videos in a slow-posting account's sample have had more time to accumulate views. One 2019 video from zachking, with 2.38 billion views, is the single most extreme point in the sample, and the reason this study reports medians instead of means. And the 7+ bucket is about 46% five habitual heavy-taggers, so read that finding as describing those five accounts' behavior, not a universal law.
## Frequently Asked Questions
### What is the #FYP hashtag on TikTok?
"FYP" stands for "For You Page," TikTok's main discovery feed, and creators add the `#fyp` hashtag hoping it helps their video get picked up by that feed. In this study, `#fyp` appeared in 156 of the 1,569 captions sampled.
### Does the #FYP hashtag actually work on TikTok?
It's associated with a real, measurable difference: videos tagged `#fyp` scored a median 1.153 against their own account's baseline, versus 0.988 for videos without it (n=156 vs n=1,413) — a roughly 16.7% gap. That's correlational, not proof of cause; creators may add `#fyp` to videos they already expect to do well.
### Should I use the #FYP hashtag on TikTok?
Based on this data, it's reasonable to include. `#fyp` is the single largest measured lever in the dataset, though it's correlational rather than causal, so treat it as worth adding, not a guaranteed lift. `#foryoupage` is a different story — it didn't appear once in this sample, so skip it.
### Is it better to post on TikTok without hashtags?
No, but only barely. The no-hashtag median normalized score was 0.975, versus 1.012 for videos with any hashtags at all — about a 3.7% relative difference. That's a small edge to using at least one hashtag, not evidence that hashtags are essential.
### What is the 3 hashtag rule?
There isn't a sourced "3 hashtag rule." The phrase appears zero times across the top competitor articles for this exact search. The closest data point, the 1-3 hashtag bucket, measured 0.967 — slightly below the no-hashtag baseline of 0.975. Using exactly a few hashtags showed no measured advantage in this dataset.
### Can TikToks go viral without hashtags?
Yes. Mega-tier accounts in this sample routinely post hashtag-free videos that vastly outperform smaller accounts in raw views, though that's mostly an account-size effect, not proof hashtags don't matter for growth generally. The single highest-view video in the entire 1,569-video sample, a 2019 post from zachking with 2.38 billion views, sits in the 1-3 hashtag bucket, not the heavy-tagging bucket.
### What is the 5 hashtag rule on TikTok?
Same answer as the 3 hashtag rule: it isn't sourced anywhere we could find, and this data doesn't isolate "exactly 5" as its own bucket. The nearest buckets are 4-6 (1.004, no measurable lift) and 7+ (1.069). There's no basis, in the competitor set or in this data, for treating 5 as a meaningful threshold.
