Hashtag generator

Turn a topic into a balanced set of broad, niche and long-tail hashtags — sized to what each platform actually rewards rather than to its maximum.

What is the post about?

Instagram: 8 recommended, 30 maximum

Instagram allows 30 but has said publicly that a small, relevant set works better than stuffing. Three to eight is the practical range.

BroadNicheLong-tail

Why the mix matters

Broad tags have huge volume and bury you within seconds. Long-tail tags have almost no competition but tiny audiences. The reach in practice comes from the niche middle — which is why this generator always gives you all three rather than thirty copies of the same size.

Generated from your topic using tier rules, not live hashtag volume data — always sanity-check a tag in the platform’s own search before you build a campaign on it.

In short

How many hashtags should you use per platform?

Instagram: three to eight, despite a limit of 30. TikTok: four or five. LinkedIn: three. YouTube: up to ten, with the first three doing most of the work. X: one or two, where more actively reduces engagement. Threads: one.

The cap is not the target. On every platform that publishes guidance, a small relevant set outperforms a large one — hashtag stuffing reads as spam to both the ranking system and the reader.

The formula

A balanced hashtag set

25% broad reach + 45% niche + 30% long-tail

Broad tags bury you instantly, long-tail tags reach almost nobody. The niche middle is where the reach actually is — so the set is weighted there.
How it works

Why tiers beat a list of popular tags

The most common hashtag advice is to find the biggest tags in your niche and use them. On a tag with ten million posts, yours is off the recent feed within seconds and has no realistic chance of ranking as a top post. You have spent a slot to reach nobody.

Long-tail tags have the opposite problem — you can genuinely rank in #sourdoughforbeginners, but the audience browsing it is small.

The useful zone is the niche middle: specific enough that your post stays visible for hours rather than seconds, broad enough that people actually look. A balanced set covers all three, so a post has a chance at immediate visibility in the small tags, a realistic shot in the middle, and a lottery ticket in the big ones.

What changed

Hashtags are topic signals now, not discovery channels

On Instagram and TikTok, hashtags have quietly changed jobs. Few people browse tag feeds any more; recommendation systems decide what to show. Hashtags still matter because they help those systems classify a post — but as a signal, not a distribution channel of their own.

That has a practical consequence: accuracy beats volume. A tag that precisely describes the post is worth more than a popular one that only loosely applies, because a mismatched signal gets your post shown to people who scroll past, which teaches the system not to show it again.

The exceptions are worth knowing. On Mastodon many people follow hashtags directly, so tags do genuine discovery work. Pinterest is a search engine where keywords in the description matter more than tags. LinkedIn sits in between.

Before you post

Check the caption length too

Hashtags count against your caption limit on most networks — TikTok in particular, where the caption is short and every tag competes with your hook. Run the finished post through the character counter before you publish, so a set that pushed you over the limit does not get discovered at the worst possible moment.

FAQ

Common questions

How many hashtags should I use?

Far fewer than the maximum. Instagram allows 30 but has said publicly that a small relevant set works better — three to eight is the practical range. TikTok works best with four or five, LinkedIn with three, and X with one or two, where more than that measurably reduces engagement. Threads supports a single topic tag per post.

Do hashtags still work?

They work differently than they used to. On Instagram and TikTok they now function mainly as topic signals that help the recommendation system understand what a post is about, rather than as discovery channels people browse. On Mastodon, Pinterest and LinkedIn they still do real discovery work, because users genuinely follow and search tags there.

Should I use popular or niche hashtags?

A mix, weighted towards the middle. Very popular tags have enormous volume and bury your post within seconds. Very small tags have almost no competition and almost no audience. Most of the reach in practice comes from mid-sized niche tags — which is why this generator always returns all three tiers rather than thirty tags of the same size.

Where should I put hashtags — caption or first comment?

Instagram has confirmed it makes no difference to reach, so use whichever looks better. The caption is simpler and survives if the comment is ever deleted. On LinkedIn and X, hashtags work best woven into the sentence rather than stacked at the end.

Can I reuse the same hashtag set on every post?

Better not to. Identical tag blocks across every post look automated and, more practically, mean you are describing different content with the same topic signal. Keep your branded tags constant and vary the rest to match what each post is actually about.

Does this tool use real hashtag volume data?

No, and it says so. It builds a balanced set from your topic using tier rules — broad, niche and long-tail — because no platform exposes reliable hashtag volume through a free public API. Always sanity-check a tag in the platform's own search before building a campaign on it.
