Hashtag generator for Instagram, TikTok, YouTube and LinkedIn

A hashtag generator picks the hashtags for a post. Type your website and ours reads it, then picks three sets for your business: reach tags people search for your category, niche tags for what you actually do, and brand tags made from your name. It works for Instagram, TikTok, YouTube and LinkedIn, with no spam tags.

Free. One run a day without an account, 20 with a free one.

How it writes

Three small sets: a few broad tags people search, a few for what you actually do, and one or two with your name. No #fyp, no tags about likes or follows.

Platform

Example for a coffee shop

  1. 1 · Reach: who searches the category

    #coffeeshop #specialtycoffee #cafe

  2. 2 · Niche: what you actually do

    #bondicafe #bondicoffee #houseroasted #freshbakedpastries

  3. 3 · Brand: your own name

    #HarbourCoffee #HarbourCoffeeBondi

What makes a hashtag set work

The rules our writer follows when it picks hashtags.

  • House rule

    Mix reach, niche and brand

    A few broad tags people search, a few for what you actually do, and your own name. Broad tags alone put you in a crowd; niche tags alone reach almost nobody.

  • House rule

    Only tags about your business

    Every tag names your category, your service, your place or your name. A tag that's popular but unrelated tells the platform the wrong thing about your post.

  • House rule

    No spam tags

    Never #fyp, #viral, #explore, #followforfollow or tags about likes. Our checks drop them before you see a set.

  • House rule

    Fewer, better tags

    Instagram and TikTok both cap posts at 5 hashtags now, and YouTube ignores every hashtag on a video with more than 60.

Counts are the platforms' own limits, linked below; the rules are Postdom's house rules, not measurements.

3 to 5on TikTok: posts are capped at 5 since August 2025
3 to 5on YouTube: up to 3 show by your title, and more than 60 means all are ignored
3 at moston LinkedIn: our house rule, so the post reads as words, not tags

Questions

Is the hashtag generator free?

Yes. Without an account you get one run a day and see 2 of its 3 sets in full. Sign up free to see all 3, get 20 runs a day and get the finished posts.

Why three sets?

Reach tags are what people search for your category, niche tags are what you actually do or where, and brand tags are your name. A post does best with a few from each, not 30 of one kind.

How many hashtags should I use?

3 to 5 on Instagram, TikTok and YouTube, and 3 at most on LinkedIn. Instagram and TikTok now cap posts at 5, and YouTube ignores every hashtag on a video with more than 60.

Do hashtags still help reach?

They help the platform understand what a post is about, which matters more than the count. Instagram's head, Adam Mosseri, has said a few specific tags beat a long list of generic ones.

Why doesn't it suggest #fyp or #viral?

Those tags say nothing about your business, so they don't help anyone find it. Our checks drop them, along with tags about likes and follows.

What does Postdom do with my website?

It reads your homepage once to write the hashtags. It doesn't create an account or post anything. Results are kept for 7 days, so the same site gets the same hashtags.
