You finish your day, you finally have your photo, then you get stuck on the caption and its list of tags. How many tags should you really put under a post, and does it still do anything? Instagram hashtags help people who don't follow you yet find your content, as long as you aim accurately.
A few precise, well-chosen tags are worth more than a giant list. You'll see how to spot the ones that fit your activity, avoid the pitfalls that slow your reach, and make a brand hashtag come alive. You keep control over every choice.
The essentials
- Instagram sets a limit of 30 tags per post: a ceiling not to aim for.
- Favor a few precise tags from your industry over giant, already saturated words.
- You can tag up to 20 people on your post, in addition to your tags.
- A loyal brand hashtag and avoiding banned hashtags make a difference to your reach.

What is a hashtag on Instagram?
A hashtag is a word preceded by the # sign, like #cuisine or #voyage. Once published, it becomes a clickable link that groups all posts using it.
Its role is simple: get you found by people who don't follow you yet. Someone searching a word in Instagram's search can land on your post, without you paying for a single ad. For a small online shop, it's a valuable lever to get known.
Be aware, however: hashtags on Instagram work on posts as well as Reels, but they never replace a clear caption. Without engaged followers who like, comment and share, a tag alone only creates short-lived visibility. Used well, it can also surface your post in the feed of interested people. To find your first words, try our hashtag generator.
How many hashtags should you put under a post?
Instagram allows up to 30 tags per post, but this number is a ceiling, not a target to reach. What matters is the relevance of each word you add.
Filling the maximum with generic words dilutes your message. A soap shop that lines up "#beauty" and "#fashion" mostly attracts the wrong people. The Instagram algorithm then misunderstands what you sell.
A handful of precise tags, describing what your post really shows, is better. For a green clay soap, three or four exact keywords do more good than a list of thirty hashtags.
The right volume depends on your industry and the size of your community, not on a magic number. A small local shop doesn't have the same ground as an account followed by influencers. Place them after the useful text, at the end of the caption or in the first comment, so your hook stays readable, without a wall of hash signs.
How to choose hashtags that fit your activity
To make your content fit your activity, combine three families: an industry term, a niche term and, if you sell in person, a location term. The right balance mixes a broad term that makes you known in your field with precise terms that speak to those who actually buy. Here is how these families split by role, use and risk.
| Type | Role | Example | Use | Risk |
|---|---|---|---|---|
| Industry | Get known | #beauty | Your field in general | Highly competitive |
| Niche | Reach a precise audience | #artisanalsoap | What your post shows | Small but engaged audience |
| Location | Attract nearby customers | #paris | Local shop | Too broad for a small area |
| Popular and competitors | Get inspired | #lifestyle | Ideas and trends | Direct copy, post drowned out |
To read this table, start from your business: a local soap shop focuses on location and niche, an online brand on industry. If you run a one-off campaign, a dedicated niche word does the job. And before reusing a term seen with your competitors, check it isn't among the banned hashtags.
Banned hashtags and mistakes that slow your reach
A banned or prohibited hashtag can drop your reach, so check each keyword before reusing it. Instagram sometimes removes certain banned tags from search, and a post containing them loses its visibility without warning. The reflex: type the word into search before publishing, and drop those that only return off-topic results or that are among the banned hashtags.
The next pitfall is copy-pasting. Putting the same block under every post tires your audience, who eventually ignore it. Vary according to the post's subject, and keep only a stable base, like your brand word.
Popular hashtags, the ones millions of posts already use, drown your post in seconds. Keep them in small doses and complement them with terms that really speak to your industry.
Watch the first 24 hours after publishing. If it doesn't take, adjust your voice without redoing everything: change one or two tags and rework the first sentence of your caption.
Brand hashtag and community: how to make them live
A brand hashtag, always the same, gathers your posts and those of your customers in one feed. Choose a unique word, use it everywhere and invite your customers to reuse it. You can then find all the photos in one place.
Tagging people in a post helps make your work known, within the limit set by Instagram. When you tag a customer wearing your piece, she gets a notification and her network can discover you. Don't overdo it, an off-topic tag annoys people.
Influencers bring their own campaign keywords, which reach an already engaged community. An online shop launches a keyword for its collection, reposts customer posts and tags the relevant partners. Its reach grows accordingly.
To get started, limit yourself to three hashtags: your brand's, the campaign's and a city tag. A campaign only takes off if you reply to comments and show the community day to day. Without that, even popular hashtags don't compensate for silence.
Our view: AI suggests the hashtags, you validate
At heart, the rule is simple: let a machine prepare the list, but never publish it without review. A word may fit your topic and attract an audience that will never buy anything. AI moves fast and keeps your pace, but you have the final say on the final choice. The right balance: time saved on writing, and human control over the final selection.
Concretely, the workflow we advocate looks like this. AI prepares a batch of Instagram hashtags for each post, based on the caption and theme. You review, remove what smells off-topic, and keep what truly speaks to your community and fuels engagement. And this week, take your last five posts, spot the tags that brought you visibility with people genuinely interested, and keep them as the base for your next lists.

Running your hashtags on autopilot while staying in control
You can hand the writing of your hashtags to Ava without letting go of your page. Ava creates your complete post: text, visual, keywords and first comment, from an idea, a photo or your shop. No more searching for the right words every evening.
Nothing goes out without your agreement. If a keyword seems too generic or too close to your competitors', you remove it before publishing. The result: your engagement stays tied to your brand voice.
On accounts, connect them through official Meta access and favor a professional account for auto-publishing. A Shopify shop testifies: "Thanks to Dropapost, I publish 3x more without spending my evenings on it." The gain comes from consistency, and organic reach follows when your rhythm holds. Start your free trial and watch your first post take shape.
Frequently asked questions
Do Gen Z use hashtags?
Yes, but not necessarily the way previous generations did. Many young people use Instagram hashtags to search for a specific topic, so finer words than "#love" have a better chance of being found. Concretely, if you sell handmade candles, a keyword about soy wax will hit closer than a giant word. Test these choices on your posts and see what truly attracts your followers.
What replaces hashtags on Instagram?
Nothing truly replaces tags for now, but they are no longer the only lever. You can tag the relevant accounts on your post, which links your content to real people. Also weave your keywords into the caption, where they read like a sentence. If you want to save time on the list, try Dropapost on your account.
