Your post is ready, the photo is great, and you're stuck on hashtags at the last minute. A hashtag generator can save you time, but it doesn't choose for you. It suggests, you choose, you review: that's the rule that avoids bad surprises. You'll discover how an Instagram hashtag generator works, how many tags to use, which mix to favor to gain reach, and how to stay compliant with the Advertisement disclosure when you launch a sponsored post.
The essentials
- Instagram limits posts to 5 hashtags, Reels included, according to the specialized press.
- Hashtags beyond the limit are not taken into account, and this rule is not confirmed in the official help center.
- Without an "Advertisement" disclosure on a promotion: up to 2 years in prison and a €300,000 fine.
- The DGCCRF audited more than 300 influencers in 2022 and 2023, and nearly half had an irregularity.
- Dropapost prepares your hashtags with each post, and nothing goes out without your approval.

How does an Instagram hashtag generator work?
A hashtag generator asks you for a theme or keyword, then returns lists of tags grouped by popularity or niche. Concretely, you type "plant-based cooking" and the tool shows you blocks of tags, some very popular, others more confidential. It's quick, and it helps generate ideas when you're stuck in front of your post.
Know that there is no length limit for a hashtag. That said, short tags are easier to remember and reuse from one post to the next. In other words, a clear word is better than a whole phrase stuck to the hash sign.
The tool starts from the subject, never from your followers or your voice. So a niche hashtag found by a generator may attract people who have nothing to do with you. The number of tags allowed per post has recently changed, according to the Blog du Modérateur, so check the rule before publishing.
The right reflex? Keep three to four lists of ideas, then do your sorting by hand according to what you actually publish. For the caption that goes with your tags, you can also try our Instagram bio generator.
How many hashtags should you put on an Instagram post?
Today, the rule comes down to one number: five hashtags maximum per post, Reels included. Beyond five, Instagram ignores the extra tags, so the last ones you add serve no purpose. According to the Blog du Modérateur article, the limit was announced by Instagram on its official @creators account, and it replaces the former cap of 30.
You'll still come across guides talking about 30 hashtags, but that figure is outdated and should no longer be followed. For Reels hashtags, it's better to choose few and well-targeted ones, rather than filling the slots out of habit. If you're looking for ideas, an Instagram hashtag generator can produce lists, and then it's up to you to sort out the five that truly fit your content. To go further on this sorting, read our hashtag guide.
Before publishing, check the rule directly in the app, since it doesn't yet appear in the official help center. A limit that changes quietly can make you lose tags without you noticing.
Which hashtag mix to gain reach and engagement?
The right mix combines popular, niche, trending and brand hashtags, rather than piling on ten of the same type. For your Instagram hashtags, each family has a precise role, and none does the job of the others.
The table compares what each family concretely brings you.
| Hashtag type | What it brings | When to use it |
|---|---|---|
| Popular | Raw visibility, but quickly drowned in the feed | To widen reach |
| Niche | An audience that truly cares about your subject | To boost engagement |
| Trending | Link to current events, useful for a Reels | Only if the content fits |
| Brand | Gathers your community and finds your posts | On every post |
To read the table, start from your subject: a popular tag makes you seen, and niche hashtags help you find the right people. Trending hashtags are only worth it if the content deserves them, otherwise they blur your message. According to Centre Inffo, the law regulates promotion done by influencers, so a news tag must never mask a paid collaboration. To choose your keywords, reuse the ones your customers actually type, then test your visuals with our AI image generator.
A concrete example: a Reels for your shop
A shop launching handmade candles keeps one brand hashtag, two niche ones, a seasonal trending tag and a popular one. Imagine it publishes a Reels video about its new collection. The brand tag gathers everything coming from it, the two niche hashtags speak to people actively looking for artisanal candles, and the trending hashtags benefit from the season. The popular one gives a raw reach boost.
The smartest part is the caption. It reuses the words customers actually type, like "natural candle" or "Mother's Day gift", instead of marketing phrases nobody searches for. So the post's visibility depends on the text too, not only on the tags. To find these starting ideas, the shop uses a free hashtag generator, then sorts by hand.
Before publishing, it re-reads the list and removes any tag without a direct link to the content. A popular tag unrelated to candles brings in no one interested, it just adds noise. If a paid collaboration is added to the Reels, also keep the DGCCRF in mind, which oversees this sector, as detailed in its review of checks on commercial influence.
Advertisement disclosure: the hashtag is not enough
A hashtag never replaces the mandatory disclosure when you promote a product, a service or a cause. The law requires the "Advertisement" or "Commercial collaboration" mention to be visible directly on the image or video, clear, legible and identifiable. The hashtag serves to be found, the disclosure serves to stay compliant.
Concretely, it must not hide at the bottom of the caption, in the middle of five lines of hashtags. A short wording placed on the visual or displayed on the video throughout the promotion does the job. Under French law no. 2023-451 of 9 June 2023, the mention must be readable without effort, as detailed in the official text on Légifrance.
An AI hashtag generator can help you find the right tags, but it doesn't check this disclosure for you. The sanctions are criminal and weigh far more heavily than a failed post or a drop in engagement. A simple oversight can therefore cost you dearly, even with a well-chosen brand hashtag.
Our view: a generator suggests, you validate
You've probably experienced it: it's 6 pm, your post is ready, but you're still searching for hashtags at the last minute. A generator can help you out of this dead end, which is why it's found everywhere. It doesn't replace, however, your knowledge of your brand, your audience, or your brand voice. A list pulled from a third-party tool may contain heavily used tags that nobody really follows, or tags that don't speak to your target.
Concretely, it happens in two stages. The generator gives you leads, broad tags and more precise tags around your product. You re-read them, remove those that don't fit your brand voice, then validate. A hashtag strategy is built this way, by hand, and this re-reading is what makes the difference between a coherent post and a list of copy-pasted keywords. Your action this week: open your latest posts, spot the tags you copy without thinking, and replace them one by one with a tag more specific to your activity.

Frequently asked questions
Is a free hashtag generator enough for a good strategy?
No, a free generator helps you find ideas, but it knows neither your audience nor your sector. A hashtag is a keyword preceded by the # sign that classifies your post. Concretely, a hashtag strategy fits in a small list of relevant tags, tested and adjusted. So keep those that attract people interested in your world, and discard those that only drown your post.
Are AI-generated hashtags reliable?
Not always. An AI hashtag generator assembles tags close to your keywords, without seeing whether a tag is saturated with off-topic content or no longer serves anyone. As a result, you may receive suggestions that are too generic or misdirected. Check each tag by looking at the posts that use it, and keep only those that fit your post.
Can you rely solely on a hashtag generator?
No, a generator remains a starting point, and the decision is yours. The real work is aligning the tags with your brand voice and your publishing rhythm. If you want help with all this, Dropapost prepares the hashtags for each post, and you validate before it goes out. You stay in control and your time goes elsewhere. Start your 7-day free trial.
