Hashtag generator

This free hashtag generator turns a topic into hashtag suggestions in groups: broad, niche, branded-style and community tags. Pick a platform to fit its rules, from Threads’ one topic tag to YouTube’s 60. It is template-based, with no live trend or volume data, so check each tag on the platform before you post.

Generate hashtags for your post

Type a topic and pick the platform; the suggestions and the cap follow its rules.

There is no single right count — it depends entirely on the platform. Use the general list below as a starting point, then switch to a platform-specific generator for a tighter, tailored set.

20 suggestions across 4 categories

Broad / high-volume style

Umbrella tags for your general niche, structural — not measured volume.

  • #veganbakery
  • #foodie
  • #foodstagram
  • #instafood
  • #foodlover

Niche / specific

Compound tags built from your exact topic.

  • #vegan
  • #bakery
  • #veganbakerytips
  • #veganbakeryideas
  • #veganbakeryguide

Branded-style

A template — swap in your own brand, product or campaign name.

  • #VeganBakeryOfficial
  • #TeamVeganBakery
  • #VeganBakeryHQ
  • #VeganBakeryCo
  • #VeganBakeryNation

Community

Tags aimed at people who identify with the topic, not just search for it.

  • #veganbakerycommunity
  • #veganbakeryfamily
  • #veganbakerycrew
  • #veganbakerysquad
  • #veganbakerytribe

Template-based suggestions, not AI, and not real-time trend or volume data — SkedCast has no hashtag-volume API. Research each tag on the platform itself before you use it. Nothing you type here is uploaded or stored; suggestions are generated entirely in your browser.

How many hashtags should you use on each platform?

Each platform sets its own limit and rewards its own habits. The caps below are the ones SkedCast’s composer enforces, and the guidance is what the generator follows for each platform:

Hashtags by platform (SkedCast composer rules, 2026)
PlatformCapGuidance
X (Twitter)No fixed capX recommends no more than two hashtags per post; each one also counts toward the 280 characters, and none can contain spaces or punctuation.
LinkedInNo fixed capLinkedIn rewards restraint: 3–5 professional, industry-specific tags outperform a long list, and keyword-rich post text now matters more here than hashtags do.
Instagram30Instagram is moving to 5 hashtags per post and Reel — pick the ones that most precisely match the post, not the longest list.
Facebook PagesNo fixed capFacebook turns each hashtag into a clickable topic link; two or three relevant ones, each written as one word without spaces or punctuation, are enough.
TikTokNo fixed capMix one or two broad or community tags with several niche ones. TikTok counts hashtags, with captions and sounds, among the video information For You uses.
YouTube60YouTube ignores every hashtag on a video with more than 60, not just the extras, and shows up to 3 of the most engaging ones above the title, so a few relevant tags work better than many.
Threads1Threads — and SkedCast’s own Threads composer — accepts only one hashtag per post. Pick the single best match from the list below rather than combining several.
PinterestNo fixed capPinterest ranks like a search engine, so favor descriptive, keyword-rich tags over short punchy ones — think of each tag as a search phrase someone might type.
BlueskyNo fixed capBluesky’s culture is casual and hashtags are lightly used — a couple of relevant tags is plenty; more will not read as normal for the platform.
TelegramNo fixed capTelegram channels mostly use hashtags for in-channel search — a few consistent tags reused across posts work better than a large, varying set.
Google Business ProfileNo fixed capGoogle Business Profile posts have no hashtags — people find them through Search and Maps, so put the words they would search for in the post text instead.

How do Threads topic tags work?

Threads calls them topic tags, and a post gets one. Meta’s Threads documentation allows one tag per post, 1 to 50 characters; a tag can be set on its own or typed with a # in the text, where the first valid tag counts. So pick the single best match from the generator’s Threads list instead of combining several. The Threads character counter checks the rest of the post.

Do hashtags help on Pinterest?

Less than keywords do. People find Pins by searching, and Pinterest matches those searches against the words in a Pin’s title and description, so a descriptive, search-style phrase does more than a short punchy tag. The generator’s Pinterest list is built that way: keyword-style tags you can use as tags or as phrases in the description. The Pinterest character counter keeps the title and description within their limits.

Do hashtags work on Bluesky?

Yes. A hashtag in a Bluesky post becomes a tag (a rich-text facet in the AT Protocol) that readers can tap to see other posts using it, and it costs only its own characters from the 300. Bluesky’s culture is casual, so a couple of relevant tags reads as normal; a long list does not. See Bluesky post limits for the rest.

How do you use the hashtag generator?

  1. Enter your topic. Type the topic, niche or product your post is about — a word or a short phrase works best.
  2. Read the categorized suggestions. Pick the platform you are posting to, or keep every platform; the generator returns hashtags grouped by category for it.
  3. Pick a handful, not the whole list. Choose the tags that most precisely match this specific post rather than pasting in every suggestion at once.
  4. Check each tag before publishing. Search each tag on the platform you are posting to first, since this tool has no live trend or volume data to confirm it.
  5. Copy and use them. Copy the ones you picked and paste them into your caption, description or first comment.

What does it look like in practice?

Topic: "vegan bakery"

For "vegan bakery" on every platform, the generator returns 4 categories totaling 20 suggested tags. The "Broad / high-volume style" group alone returns 5: #veganbakery, #foodie, #foodstagram, #instafood.

Topic: "fitness coach"

For "fitness coach" on every platform, the generator returns 4 categories totaling 20 suggested tags. The "Broad / high-volume style" group alone returns 5: #fitnesscoach, #fitness, #fitfam, #workout.

How do you schedule posts with the right hashtags?

In SkedCast, write the post once and give each platform its own version: a full set on Instagram, three to five on LinkedIn, one topic tag on Threads. The composer checks each platform’s cap before the post is scheduled, and saved hashtag groups keep your regular sets one click away. See the hashtag limits by platform and the hashtag counter.

Hashtag generator FAQ

Is the Hashtag generator AI?
No. It combines your topic with a set of structural patterns — broad umbrella tags for a detected niche, niche-specific compounds, and platform-appropriate styles — rather than generating text with a model.
Does it use real-time hashtag trend or volume data?
No. SkedCast has no hashtag-volume or trend API, so nothing here reflects real, current popularity. These are structural suggestions built from your topic and common patterns, not measured data — research further before you rely on any of them.
How many hashtags should I use on social media?
There is no single right count — it depends entirely on the platform. Use the general list below as a starting point, then switch to a platform-specific generator for a tighter, tailored set.
Does every platform limit how many hashtags I can use?
SkedCast’s product does not enforce a hard cap on every platform hashtags, but more is not automatically better — see the guidance above for a practical range to aim for instead.
Does the Hashtag generator store or send my topic anywhere?
No. Suggestions are generated entirely in your browser as you type — nothing is uploaded, saved, or sent to a server.
Can I use these hashtags exactly as generated?
Treat them as a first draft: check each one is still relevant to this specific post, is not already associated with something unrelated, and fits the platform you are posting to norms before you publish.
Why are the suggestions grouped into categories instead of one list?
Different tag types serve different purposes: broad tags reach a wider audience, niche tags reach a more relevant one, and so on. Picking a mix deliberately, rather than grabbing the first several, is closer to how experienced marketers actually choose hashtags.
Do hashtag limits differ by platform?
Yes, significantly. Instagram 30, YouTube 60, Threads 1 are hard, product-enforced caps; other platforms have no enforced cap but still have their own informal norms, covered on each platform-specific generator linked below.
How many hashtags can you use on Threads?
One. Threads allows one topic tag per post, 1 to 50 characters, per Meta’s Threads documentation; if a post has several # tags, the first valid one becomes the tag.
Do hashtags work on Pinterest?
They matter less than keywords. Pinterest finds Pins by the words in their title and description, so write descriptive, search-style phrases and keep any tags few and specific.
Do hashtags work on Bluesky?
Yes. A hashtag in a Bluesky post becomes a clickable tag that opens a feed of posts using it; a couple of relevant tags is normal.
