Hashtag Generator

What is a hashtag generator and what does this one do?

A hashtag generator suggests the tags to add to a post, starting from what the post is about. This hashtag generator does three jobs at once: it derives tags from your topic, adds big, medium and niche tags from the bank of your chosen niche, and then picks a ready set that follows the platform rule. As a result, you get 15 suggestions and a set ready to copy.

The first version of this tool existed to fill Instagram's old 30 tag allowance. When Instagram cut the limit to 5, I rebuilt it from scratch. The goal is no longer to find many tags; it is to choose the right five. That is why the suggestion list works like a pool:

• Topic tags: built from your own words, such as #winteroutfit, #winter and #outfit.
• Big tags: broad tags with heavy search and heavy competition.
• Medium tags: tags that balance your chance of staying visible with volume.
• Niche tags: searched less, but the person searching wants exactly your content.

In practice, the tool runs entirely in your browser and does not measure search volume. The tiers are a guide I compiled from tags I use in client work, not a live measurement.

How many hashtags can you use on Instagram now?

Short answer: five. In December 2025 Instagram announced that it would gradually reduce the number of hashtags you can add to a post or Reel caption to 5. The reasoning in the announcement is clear: a few targeted tags, rather than many generic ones, improve both content performance and the experience on the app (Social Media Today).

This change ended the habit of pasting a 30 tag block. Instagram's head, Adam Mosseri, has also said many times that hashtags do not grow reach. Therefore each of your five tags needs a clear job:

1. One topic tag that names what the post is about.
2. One big tag that points to the broad category.
3. Two medium tags that the community actually uses.
4. One niche tag that speaks to the exact audience.

The Instagram ready set in the tool applies exactly this mix. If you leave the topic empty, a second niche tag takes the place of the topic tag. Select more than five and the badge turns red; in that case, simply remove one.

How do you balance big, medium and niche hashtags?

Thinking in three tiers matters even more when you only have five slots. Every tag has a cost: one poorly chosen big tag takes the place of a niche tag that could have worked.

• Big tag: for example #fashion or #travel. Volume is high, but your post drops down the feed fast. One is enough to name the broad category.
• Medium tag: for example #outfitinspo or #roadtrip. This is the most balanced zone between search and competition, so these tags form the body of the set.
• Niche tag: for example #capsulewardrobe or #solotravel. Few people search it; however, those who do want exactly your content.

Here is what I see on my own and client accounts: small and mid-size accounts get almost no visibility from big tags. So the tool gives a big tag a single slot. On the other hand, going niche only is risky too; a very narrow tag puts the post on a page that almost nobody visits.

The borders between tiers are not fixed. The same tag can be big in one market and medium in another. In short, treat the tiers as a starting point and decide with your own post insights.

How do hashtag rules differ on TikTok, YouTube and X?

Each platform treats hashtags differently, so copying one set everywhere rarely works. Here is the current picture:

• TikTok: since August 2025, users report seeing a 5 hashtag limit per post. TikTok has not officially explained the reason. The tool suggests a set of 4 tags for TikTok: one topic, two medium and one niche tag.
• YouTube: YouTube says it ignores every hashtag on a video that carries more than 60, and it shows up to 3 of the most engaging tags next to the title. In addition, unrelated or misleading tags can lead YouTube to remove the content (YouTube Help).
• X: there is no technical limit, but X recommends no more than 2 hashtags per post.

If you publish the same content on several platforms, keep the topic tag fixed and change the rest per platform. For example, use the five tag Instagram set for a Reel and the four tag set for the TikTok version of the same video. When you press the platform button, the tool rebuilds the set by that rule.

On TikTok the video itself does most of the talking. Making the topic clear in the first seconds and using the same words in the caption helps more than adding tags.

How do you adapt hashtag generator results to your account?

The tool gives you a solid starting set; the final call is yours. Before a set goes live, I run four checks:

1. Relevance: ask whether the post really matches each tag. If the answer is hesitant, drop the tag.
2. Tag page: search the tag on Instagram. If the page says recent posts are hidden, or it is full of unrelated content, skip that tag.
3. Brand slot: if you have a campaign or brand tag, reserve a slot for it. With a limit of five, that means removing one tag from the pool.
4. Readability: capitalizing each word in a multi-word tag (#WinterOutfit) helps screen readers pronounce it correctly (BOIA). The tool writes lowercase tags; edit them after copying.

Then measure. Track in your post insights which tags bring visitors from search and explore. Follow the overall trend with the Instagram engagement rate calculator. To check caption length, the word counter also shows platform character limits.

Hashtags or caption keywords: which matters more?

Both, but they play different roles. In November 2024 Instagram announced that it would remove the option to follow hashtags, while searching with hashtags and adding them to posts would continue (Social Media Today). In other words, a hashtag now serves search and categorization rather than a follow feed.

That is why I write captions like search copy. Use the words that describe the post inside a natural sentence, and let the tags complete that sentence instead of repeating it. For instance, if the caption of a winter outfit post already mentions a wool coat and boots, #winteroutfit and #outfitinspo are enough on the tag side.

The same logic applies to traffic to your website. If you want visitors from social media, set up your profile link and campaign links properly; I explain the steps in my guide to website traffic from social media. To see which post a campaign link visit came from, tag the links with the UTM builder.

How should you plan branded and campaign hashtags?

A branded hashtag collects your content and your customers' posts on one page. A good one is short, easy to read and does not mean anything else. Search the tag before you launch it; if someone else already uses it, add a small suffix to make it yours.

Campaign hashtags, on the other hand, run for a set period. In influencer collaborations, giving every creator the same campaign tag makes it easy to follow all posts in one place. With a limit of five, that tag becomes the fixed part of the set, and each creator fills the other four slots to match their own content. My team and I use this setup as standard in influencer marketing projects.

A campaign tag also helps in giveaways, because it makes entries easy to find. To pick a winner transparently, use the giveaway picker. And to pin down who the campaign speaks to, read my guide on target audience analysis.
