Hashtags on Instagram still matter in 2026, but they work very differently from a few years ago. Instagram now limits posts and Reels to a maximum of five hashtags in the caption, and its own advice is that a few targeted tags work better than lots of generic ones. Hashtags help Instagram understand what your post is about. They are no longer a shortcut to reach.

That makes choosing them a quick, sensible job rather than a copy and paste of 30 tags. Below we cover the current rules, how to pick the right five, where to put them, mixing broad, niche and local UK tags, why keywords in your caption now carry more weight for Instagram search, and the mistakes we still see on business accounts.

Instagram now allows five hashtags per post

For years, Instagram allowed up to 30 hashtags on a post. In December 2025, Instagram’s @creators account announced that it would gradually reduce the number of hashtags you can include in the caption of a Reel or post to five. Instagram’s explanation was that using fewer, more targeted hashtags, rather than many generic ones, works better for both performance and the experience of people browsing.

This followed a long run of comments from Instagram’s head, Adam Mosseri, who has said publicly that hashtags do not meaningfully increase reach, while also describing them as a useful way to tell people what a post is about. The practical takeaway for a business is simple:

• Five is the ceiling, not a target. Three well chosen tags beat five vague ones.
• Relevance is the whole game. Each tag should describe the post accurately.
• Hashtags support your content, they do not rescue it. A strong Reel with no hashtags will still outperform a weak one with perfect tags.

Because the change rolled out gradually, you may see older posts on Instagram with far more than five tags. Do not take that as a sign the old approach still works.

How Instagram uses hashtags now

Instagram recommends content using lots of signals: what people watch, like, share and save, plus what the post is about. To work out what a post is about, it looks at your caption text, any text on screen, audio, alt text and hashtags together. Hashtags are one clue among several.

Where they still help:

• Categorising your content, so Instagram can match it with people interested in that topic.
• Hashtag pages and search, where people tap a tag or search a term and browse related posts.
• Campaigns and communities, such as a branded hashtag for a competition or a local event tag that organisers and attendees check.

Choosing the right hashtags for each post

Start from the post, not from a list. Ask: what is this about, who is it for, and where are they? Then find tags that answer those questions. Our process when writing for a client account:

1. Describe the post in a few words. “Wedding flowers, Surrey florist, autumn bouquet.”
2. Search each idea in Instagram’s search bar. Look at the posts showing for that tag. If they are spam, giveaways or unrelated, drop it. If they look like posts your customers would browse, keep it.
3. Check the size. Very large tags are flooded and your post vanishes in seconds. Tiny tags with a handful of posts rarely get searched. Aim for tags that are clearly active and specific.
4. Match the tag to the post. A post about a bridal bouquet gets wedding tags. A post about your new shop opening hours does not.

Keep a simple bank of tested tags in a document or your scheduling tool, grouped by topic, so you are picking rather than inventing every time. Review it every few months, as tags drift in quality.

Mix broad, niche and local UK hashtags

With only five slots, balance matters. A good mix for most small businesses looks like this:

Type	What it does	Example for a Guildford bakery
Broad (1)	Tells Instagram the general topic	#Sourdough
Niche (1 to 2)	Reaches people interested in exactly this	#SourdoughBaking, #ArtisanBread
Local (1 to 2)	Reaches people nearby who can actually buy	#Guildford, #SurreyFood
Branded (optional)	Groups your own content or campaign	#YourBakeryName

Local tags are the most underused by UK businesses and often the most valuable. Think town, county and region (#Portsmouth, #Hampshire, #SouthCoast), plus local community tags people genuinely use, such as a town’s food or events tag. A follower in your town is worth far more to a salon or café than one on another continent.

Also add a location tag to the post itself using Instagram’s Add location option. It is separate from hashtags, does not count towards your five, and helps people searching places nearby find you.

Where to put your hashtags

Instagram’s five hashtag limit applies to captions on posts and Reels, and that is where we recommend putting them. Our approach:

• Put hashtags at the end of the caption, after your message and call to action, so the first lines people read are about them, not a block of tags.
• Or work one or two into a sentence where it reads naturally, such as “New autumn menu at our #Guildford café”.
• Do not try to dodge the limit by adding extra tags in the first comment. It goes against the spirit of Instagram’s guidance and, given the limit was introduced to cut down on mass tagging, it is not worth the risk to your account.
• Stories can use a hashtag sticker, which is useful for event or community tags. Keep it to one relevant tag.

Keywords in your caption now do more than hashtags

Instagram search has moved towards understanding plain words, not just tags. If someone searches “dog groomer Portsmouth”, Instagram can show accounts and posts that use those words in names, bios and captions, not only ones tagged #DogGroomer. Public posts from professional accounts can also now appear in Google search results, which makes your caption text even more valuable.

To make your posts easier to find:

• Write descriptive first lines. Say what the post shows using the words a customer would type: “Balayage and cut for autumn at our Farnham salon”.
• Use your name field. The name field on your profile is searchable. “Bloom | Florist in Guildford” works harder than just “Bloom”.
• Write a clear bio with what you do and where.
• Add alt text to images via the advanced settings when posting. It helps people using screen readers and gives Instagram another description of your image.
• Use on-screen text in Reels that names the topic, such as “3 mistakes when booking a wedding venue”.

Write for humans first. Stuffing a caption with keywords reads badly and puts people off, which hurts the engagement Instagram rewards most.

Hashtag mistakes to avoid

• Generic filler tags. #Love, #InstaGood, #PhotoOfTheDay and similar tell Instagram nothing about your business and reach no one useful.
• Tags like #Explore, #Reels or #Viral. They do not get you onto the Explore page.
• The same five tags on every post. Tags should describe each post, so they should change when the content does.
• Irrelevant trending tags. Riding a trending hashtag that has nothing to do with your post looks spammy and attracts the wrong people.
• Restricted tags. Some hashtags are limited or hidden by Instagram because they have been misused. If you tap a tag and see few or no recent posts, or a warning, avoid it.
• Hard to read tags. Use capitals for each word (#SurreyWeddings, not #surreyweddings) so people and screen readers can read them.
• Judging success by hashtags alone. In your post insights, look at where views came from. If most come from followers, Reels or Explore, that is normal. Focus on the content.

If you are putting money behind posts, hashtags make no difference to who sees your ads. Targeting is set in Meta’s ad tools, which is where our Instagram ads work focuses for clients wanting faster local reach.

Frequently asked questions

How many hashtags can you use on Instagram in 2026?

Up to five in the caption of a post or Reel. Instagram’s guidance is that fewer, more targeted hashtags work better than many generic ones.

Do hashtags still work on Instagram?

They help Instagram understand what your post is about and help people browsing a topic find it, but they are not a major driver of reach. Content quality and engagement matter far more.

Should I put hashtags in the caption or a comment?

In the caption. That is where Instagram’s five hashtag limit and guidance apply, and it keeps everything about the post in one place.

Are keywords more important than hashtags on Instagram?

For search, clear keywords in your name, bio and captions now do a lot of the work. Use both: descriptive captions plus a few relevant hashtags.
