How many hashtags should I actually use?

Instagram allows 30 but rarely rewards them. Most accounts see better results from 8–15 genuinely relevant tags than from 30 loose ones, because relevance is what the ranking signal is built on. LinkedIn tops out at 3–5, X at 1–2, TikTok at 4–6.

Why does the tool mix big and small hashtags?

A tag with twelve million posts pushes your post off the page in under a second, so it only ever pays off as a lottery ticket. A tag with forty thousand posts can keep you in its Top section for hours, and the people browsing it are far more likely to care. The mix gives you a couple of lottery tickets and a lot of real chances.

Are these hashtags AI-generated?

No. They are a hand-curated table, sorted by how crowded each tag is. A language model happily invents tags that read well and have four posts on them, which is worse than useless — you want tags people actually browse.

Should hashtags go in the caption or the first comment?

Reach is effectively identical either way, so it comes down to how you want the caption to read. The “copy for a first comment” button gives you the dot-padded block that keeps them out of the caption preview entirely.

Can I use the same hashtags on every post?

You can, and nothing will ban you for it, but you will keep reaching the same pocket of people. Change a third of the set per post and keep the ones that actually bring you profile visits — your own insights beat any generator, including this one.

Big hashtags are the wrong ones

The instinct is to reach for the biggest tag you can find. It is exactly backwards. On a tag with millions of posts, yours is visible for a second or two before it is buried, and the only people who see it are scrolling a firehose. On a tag with a few tens of thousands, a decent post can hold a spot in the Top grid for hours, in front of people who chose to look at that subject.

So the goal is not to find popular tags, it is to find the largest tags you can still rank in — which depends entirely on how big your account is. That is why this tool asks.

The three tiers

Broad — millions of posts. One or two, for the chance of a spike. Never build a set out of these.
Mid — roughly 100k to 1M. Real audiences, real chance of surfacing. The core of a good set.
Niche — under about 100k. Where a small account actually ranks, and where the most engaged people browse.
Your keyword — tags built from your own subject. Small, specific, and usually the best performers in the set.

How to make this work

Change roughly a third of your set per post. Identical sets reach an identical pocket of people.
Check your own insights after two weeks and keep whatever actually produced profile visits. Real data from your account beats every generator.
Relevance is the ranking signal. A tag that does not describe the post is worse than no tag at all.
Never paste the same 30 tags into every post from a text file — that is the pattern platforms look for.
