Instagram limits every post and reel to 5 hashtags, a cap it began rolling out on December 18, 2025. Hashtags now mainly help search and labeling: Adam Mosseri, the head of Instagram, says they don't increase reach, and people can no longer follow a hashtag. Use up to five specific tags that describe the post, put them in the caption rather than the comments, and spend more effort on the words in your name, bio and caption, which Instagram search matches too. A tag Instagram has made unsearchable adds nothing.
Checked against Instagram's Help Center, about.instagram.com, @creators announcements and Adam Mosseri's public statements on October 1, 2026. This rewrite replaces the April 2026 version, which described 30 hashtags as the maximum (the cap has been 5 since December 2025) and relied on third-party studies, a banned-hashtag list and search effects from alt text that we could not verify.
What changed for hashtags on Instagram
Hashtags used to be a distribution channel: people followed tags and browsed tag feeds, so more tags meant more places to be seen. Instagram has taken that role apart step by step.
| When | What changed |
|---|---|
| August 2021 | Instagram explained how Search works: the text people type is matched against usernames, bios, captions, hashtags and places, and keywords and hashtags belong in the caption, not the comments. |
| March 2024 | Tapping a hashtag started opening the full search results for that topic instead of a feed of top posts using the tag. |
| November 2024 | Instagram announced it was removing the option to follow hashtags. Tags people already followed stopped adding posts to their feeds. |
| December 18, 2025 | Instagram began limiting posts and reels to 5 hashtags. |
| September 2026 | Instagram's own Reels guide still suggests a caption that adds context, asks a question or includes relevant hashtags. |

Instagram's statement on dropping hashtag follows sums up where tags stand: "You will still be able to use hashtags in your posts and search with a hashtag to discover related posts. We'll continue to show you posts that are relevant to your interests via recommendations in Feed, Explore, and Reels."
How many hashtags to use in 2026
Five is the ceiling. Instagram's Help Center says: "You can use up to 5 tags on a post. If you include more than 5 tags on a single photo/video, your comment won't post."
Instagram's announcement, quoted by Social Media Today, gave the reason: "We find that using fewer (up to 5) more targeted hashtags, rather than many generic ones, can improve both your content's performance and people's experience on Instagram." Mosseri added that "a few specific tags actually perform better than a long list of generic ones," and that hashtags help with search but "don't increase your reach."
Read together: targeted tags beat generic ones, but neither is a reach lever. There is no official minimum and no bonus for filling all five slots. Use as many tags as genuinely describe the post, and none if nothing fits.
What hashtags do now, and what they don't
Mosseri has described hashtags as "a great way to let people know what a post is about and connect posts," while saying they don't improve visibility (summarized here). That is the practical split.
What they still do
- Help search match your post. Instagram matches what people type with "relevant usernames, bios, captions, hashtags and places."
- Put public posts in the tag's results. If your account is public, a tagged post "will be visible on the corresponding hashtag page." Posts from private accounts don't appear there publicly.
- Compete on timing and response. Instagram says the order of posts in hashtag results depends on factors such as when the post was shared, how others engage with it and whether it meets the Recommendation Guidelines (source).
What they no longer do
- Add reach. In Mosseri's words, they "don't increase your reach."
- Reach tag followers. Nobody can follow a hashtag anymore.
- Rescue a weak post. Reels are shown to small groups of non-followers first and widen only if people respond. Mosseri has named watch time, likes and sends as the top ranking signals; our guide to what drives Reels views covers them.
How to choose your five hashtags
- Write the caption first. Say what the post is and who it's for, in the words people would type into search.
- Turn the key terms into tags. Prefer the specific version (#sourdoughstarter) over the generic one (#food).
- Search each tag before you use it. If the results show posts like yours, it fits. If they show unrelated content, or the tag can't be searched, drop it.
- Add a place only when place matters, and tag the location too. Instagram's Reels guide says location tags help reels "show up in location-based searches."
- Pick per post. Keep a short list of tags for each content pillar and choose from it, rather than pasting the same block on everything.
An example for a reel about feeding a sourdough starter, posted by a bakery in London:
| Slot | Example | Why it is there |
|---|---|---|
| Topic | #sourdough | What the post is about |
| Specific angle | #sourdoughstarter | The exact sub-topic, a closer match for people searching it |
| Format or intent | #breadrecipe | Signals that the post teaches something |
| Place | #londonbakery | Only because the audience is local |
| Brand or community | #yourbakeryname | Only if you use it consistently so people can find all your posts |
This structure is our suggestion, not an Instagram rule. Leave a slot empty rather than filling it with a generic tag.
Caption or comments?
Both work technically: the Help Center says you can add hashtags "in the caption or comments of your post," and you can add one later by editing the caption. For search, Instagram is specific: "For a post to be found in Search, put keywords and hashtags in the caption, not the comments." So put them in the caption, at the end if you prefer a clean look.
Hashtags are the smallest part of Instagram search
In Instagram's Search explainer, the text people type is "by far the most important signal," followed by their own activity and popularity signals. Hashtags are one of five places that text is matched. The others are worth more attention:
- Handle and profile name. Instagram's advice is to use a handle or name related to your content, such as a name field that says what you do.
- Bio. Include keywords about who you are and what the profile covers, plus your location if you serve one area.
- Captions. Write the words a searcher would use, naturally, in the caption itself.
- Alt text is for people, not ranking. Instagram's Help Center says custom alt text describes photos for people with visual impairments and "will only be read if someone is using a screen reader." Write it accurately; it isn't a keyword slot.
- Search engines. Public professional accounts run by adults can have their public posts and reels indexed by search engines such as Google and Bing, so clear captions help outside the app too.
Eligibility matters as much as wording. Instagram avoids showing accounts, posts and hashtags that break its Recommendation Guidelines in search results, and accounts that post spam "may appear lower." On a professional account, Account Status shows whether your content can currently be recommended.
Banned and unsearchable hashtags
Instagram's Help Center explains: "Hashtags on Instagram may not be searchable if the text or the content associated with the hashtag consistently do not follow our Terms of Use or Community Standards." It reviews these tags periodically and may make one searchable again, and it doesn't publish a list.
- Check, don't guess. Search the tag. If Instagram won't show results for it, leave it out; it can't help anyone find your post.
- Ignore "banned hashtag" lists. Tags move in and out of that state, and the lists that circulate online can't be checked against any official source.
- Mind the tag's neighbors. Instagram says it may remove posts from a hashtag's results when people use the tag to post content that breaks its Community Standards, so a tag crowded with spam is a poor home for your post.
How to tell whether hashtags are helping
You can't measure a single tag. Instagram's post insights show views, interactions and profile activity, and reel insights show views, watch time, viewers, average watch time and follows. The Help Center lists no hashtag breakdown.
Because five tags are a small input that Instagram doesn't isolate, a hashtag experiment would need many posts before it showed anything. Spend that effort where results are visible: test hooks, formats and topics with trial reels, and keep your hashtag routine simple and consistent.
Hashtag habits to drop in 2026
- Pasting a saved block of 20 or 30 tags. Instagram now blocks anything over five.
- Hiding tags in the first comment when you want the post found in search. Instagram's guidance says caption.
- Generic giant tags such as #love or #instagood. They describe nothing about your post, which is the one job tags still have.
- Unrelated trending tags. They put your post in front of people searching for something else.
- Engagement-swap tags such as #like4like or #follow4follow. Meta's Spam policy bans exchanging engagement such as likes and follows, and tags like these advertise exactly that.
- Hashtag "laddering" by tag size and rotating sets to avoid a penalty. Instagram has never described either mechanism. Choose tags for relevance instead.
Where hashtags fit in a growth plan
Hashtags take a minute per post. Reach comes from the post itself: an opening that holds strangers, content people want to send to a friend, original work and an account that stays eligible for recommendations. Our guide to growth tactics that work in 2026 covers those. Instagram Ignited teaches hashtag and discovery research alongside Instagram SEO, trial reels and analytics, with a weekly test-and-review loop. Results depend on your niche, content and consistency.
Instagram Hashtag FAQ
How many hashtags can you use on Instagram in 2026?
Up to 5 per post or reel. Instagram began rolling out the cap on December 18, 2025, and its Help Center says that if you include more than 5 tags on a photo or video, it will not post.
Do hashtags still work on Instagram?
For search and labeling, yes. Instagram matches what people type in search against captions and hashtags, among other text. Adam Mosseri, the head of Instagram, has said hashtags help with search but do not increase reach, and people can no longer follow a hashtag.
Should Instagram hashtags go in the caption or the first comment?
In the caption. Instagram allows hashtags in comments, but its guidance on search says to put keywords and hashtags in the caption, not the comments, if you want a post to be found.
Can you still follow hashtags on Instagram?
No. Instagram announced in November 2024 that it was removing the option to follow hashtags. You can still add hashtags to posts and search for them, and Instagram says it keeps recommending posts that match your interests in Feed, Explore and Reels.
Why can't I search for a hashtag on Instagram?
Instagram makes a hashtag unsearchable when its text or the content posted with it consistently breaks its Terms of Use or Community Standards. It reviews these tags periodically and may make one searchable again. Using such a tag gives your post no benefit.
Do hashtags work differently on reels?
The same 5-tag limit applies to reels. What decides how far a reel travels is how viewers respond: Mosseri has named watch time, likes and sends as the top ranking signals. Hashtags only help a reel be matched in search.
Do I have to use hashtags at all?
No. Instagram does not require them, and Mosseri says they do not add reach. Use them when a few specific tags describe the post; clear words in your name, bio and caption matter more for search.
