Do Hashtags Actually Help? What the Data Says
Short answer: not the way most guides claim. Across tens of thousands of matured posts, more hashtags did not mean more views — on both TikTok and Instagram, posts with zero hashtags matched or beat posts loaded with them, and the 7–10 hashtag range was the worst-performing of all.

The myth, tested
Open any “grow on TikTok” guide and you’ll be told to use a specific number of hashtags. We tested that advice against tens of thousands of matured posts on TikTok and Instagram, grouping each by how many hashtags it used and comparing median views.
The result is the table above — and it’s not what the playbooks promise. More hashtags did not mean more views. On both platforms, posts with zero hashtags performed as well as or better than posts with several, and the 7–10 hashtag band was the worst of all (a roughly 54% drop versus zero-hashtag posts on TikTok).
Why hashtags underwhelm
On a For You–driven platform — and 85% of TikTok views come from the For You page — discovery isn’t powered by hashtag search the way it is on, say, older Instagram. The algorithm decides who sees a clip based on how it performs, not which tags it carries. Hashtags can still signal topic, but they’re a rounding error next to retention and the hook.
What to do instead
Don’t agonize over hashtags. A few relevant tags won’t hurt; ten won’t help. The time you’d spend researching hashtag sets is far better spent on the clip itself — a stronger hook, a tighter cut, on-screen captions. quso.ai’s AI Clips Generator helps you turn long videos into tight, high-performing clips, which is where the real gains are.
Frequently asked questions
Do hashtags increase views on TikTok or Instagram?+
Not reliably. In our data, posts with zero hashtags performed as well as or better than posts with many, and the 7–10 hashtag range was the lowest-performing on both platforms. Hashtags are not the lever creators think they are — the content and hook matter far more.
How many hashtags should I use?+
If anything, fewer. The data shows no payoff from stacking hashtags, and a clear dip in the 7–10 range. A handful of genuinely relevant tags is fine; padding your caption with ten is, if anything, counterproductive.
