MagikDo hashtags still work in 2026?
The thirty-hashtag block isn't just out of fashion — since December 2025 Instagram won't let you post one. Captions are capped at five. That change, and the two before it, add up to a clear answer about what hashtags are for now, and it isn't what most stores are still doing.
The short answer
Hashtags classify. They don't distribute. Adam Mosseri's position is blunt: "Contrary to popular belief, hashtags are not a way to get more reach… generally speaking, no, hashtags do not improve your reach." Instagram has since removed the ability to follow hashtags and capped captions at five. On TikTok they matter slightly more — TikTok's own explainer lists hashtags inside its ranking signals — but there too they describe the video rather than promote it.
So the practical rule for a store is the same on both: three to five specific, genuinely relevant tags, and move the effort into the caption itself. The plain words describing what the product is now do more work than any tag block ever did.
Below: the three Instagram changes and their exact wording, why TikTok is different, an annotated example of what a product caption should look like now, and a verdict on each type of hashtag stores use.
What actually changed on Instagram
Three separate moves over about two years, each one pointing the same direction. Taken individually they look like housekeeping; together they're a fairly complete retirement of the hashtag as a growth tactic.
The cap, in Instagram's words
Announcing the change, Instagram said it "will gradually update the number of hashtags that you can include in a caption for a reel or post to five," adding: "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." It had been testing a three-tag limit for roughly a year first, so five is the generous end of what it considered.
The removal, in Instagram's words
A year earlier: "We're removing the ability to follow a hashtag on Instagram. 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." That last sentence is the whole strategy — discovery moved from tags you subscribe to, to recommendations the system makes for you.
It's also worth noticing what Instagram's own ranking documentation doesn't say. Its published explanation of Reels ranking describes predictions about whether you'll "reshare a reel, watch a reel all the way through, like it, and go to the audio page." No hashtag term appears anywhere in that list.
TikTok is genuinely different
This is where blanket "hashtags are dead" advice goes wrong. TikTok's published explanation of the For You feed names three categories of ranking signal — and hashtags are explicitly inside one of them. TikTok lists "video information" as a ranking input and defines it as "captions, sounds, and hashtags."
That's a meaningful difference from Instagram, but it's easy to over-read. A hashtag on TikTok is an input that helps the system work out what your video is about and who might want it. It isn't a queue you join or an audience you borrow. The video still has to earn the watch once it's shown.
| TikTok | ||
|---|---|---|
| Named as a ranking input? | Not in the published Reels ranking predictions | Yes — inside "video information" |
| Limit per post | Five, from December 2025 | No published cap |
| Can people follow a hashtag? | No — removed late 2024 | No |
| Official line on reach | Mosseri: "hashtags do not improve your reach" | No equivalent statement either way |
| Sensible number to use | 3–5, specific | 3–5, specific |
The bottom row is the same on both, for different reasons. On Instagram because five is the ceiling. On TikTok because a tag that describes the video accurately is a useful signal and a tag that doesn't is a misleading one — and there are only so many accurate tags for a linen shirt.
What a product caption should look like now
If tags aren't doing the work, the caption is. Both platforms have moved toward understanding what a post is about, which means plain descriptive language — the words a customer would actually type — earns its place where a tag block used to sit.
One caveat worth stating, because plenty of pages won't: the advice to write descriptive, keyword-bearing captions is well grounded in what the platforms say about understanding content, but the specific numbers floating around — "keyword captions get 30% more reach" and similar — come from vendor blogs with no disclosed sample or method. We're not repeating them. The reasoning stands on the platforms' own descriptions of how they classify posts, not on invented percentages.
A verdict on each kind of hashtag
Stores tend to use five categories of tag without distinguishing between them. They have genuinely different value now, and with only five slots the choice matters more than it used to.
| Type | Example | Verdict |
|---|---|---|
| Product-specific | #washablelinen | Keep. The most accurate description of what you're selling, and the closest thing to a search term. |
| Niche community | #slowfashion | Keep. Narrow enough to genuinely describe your buyer, which is what the classification is for. |
| Branded | #yourstorename | Keep one. Useful as a collection point for your own posts and customer content — not as reach. |
| Broad category | #fashion, #shopping | Drop. Describes millions of posts, so it distinguishes nothing and wastes one of five slots. |
| Trending but unrelated | Whatever's on the trending list | Drop, actively. Tells the system your video is about something it isn't, so it gets shown to people who scroll past. |
That last row is worth dwelling on, because it's the one people still think is a growth hack. Both platforms rank on watch behaviour — TikTok weighs whether someone finishes a video, Instagram predicts whether you'll watch it through. Attaching an irrelevant trending tag gets your video in front of people with no interest in it, who then scroll immediately. You haven't borrowed the trend's audience; you've fed the system evidence that your video doesn't hold attention.
So where should the effort go?
Hashtags were always a cheap lever, which is why they were popular. The honest version of this article is that the cheap lever has been removed and what's left is the expensive one: making something worth watching. But there are a few things in between that are genuinely worth doing.
- Write the first line for a stranger. Not "new drop 🖤" — the specific thing, in the words a buyer would use. It's the line that gets matched in search and the line a scroller reads before deciding.
- Say it and show it, not just type it. Both platforms read on-screen text and audio as evidence of what a video is about, so repeating your key words in the voiceover and as a caption overlay costs nothing and adds signal.
- Pick five tags on purpose, or fewer. Two accurate ones beat five with three generic fillers. There's no prize for filling the allowance.
- Then stop optimising this. Hashtags are now a smaller lever than posting time, which is itself a smaller lever than most guides admit. If you're spending more than a minute per post on tags, that minute is better spent on posting more often.
Where this leaves the caption
There's a quiet consequence in all this for anyone automating their posting. When hashtags carried the discovery load, a generic caption plus a big tag block was a viable formula, and plenty of tools were built for exactly that. Now that the tags are capped and demoted, the caption text itself is the part that tells the platform what you're selling — which makes a caption written from your real product data meaningfully different from a template with the product name dropped into it.
That's the part Magik writes from the actual Shopify catalogue — the real product title, description and price, in your language and tone, rather than a fill-in-the-blank line. It's a small thing that got more important in December 2025. Everything else on this page applies whichever tool you use, or none: what you post and what format you post it in are still much larger levers than anything in a caption.
And once posts are going out, make sure you can tell whether they're working — untagged social traffic lands in Shopify as "Direct" and gets excluded from its default attribution model, which is a far more expensive measurement problem than any hashtag decision.
Frequently asked
Do hashtags still work on Instagram in 2026?
Not for reach. Mosseri's position is that "contrary to popular belief, hashtags are not a way to get more reach" and that "generally speaking, no, hashtags do not improve your reach" — they're "useful for things like search." Instagram has matched that with product changes: hashtag following removed in late 2024, and captions capped at five hashtags from December 2025. They still classify your post, which matters for search and topic matching.
How many hashtags can you use on Instagram now?
Five. Instagram said it would "gradually update the number of hashtags that you can include in a caption for a reel or post to five," on the basis 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." It had tested a three-tag limit for about a year first.
Do hashtags work on TikTok?
More than on Instagram, but still as description rather than promotion. TikTok's published explanation of the For You feed lists "video information" among its ranking inputs and defines that as "captions, sounds, and hashtags." So a hashtag genuinely helps TikTok work out what your video is about — it just doesn't hand you an audience.
Why did Instagram remove hashtag following?
Spam. Its statement said people could "still be able to use hashtags in your posts and search with a hashtag to discover related posts," and that it would "continue to show you posts that are relevant to your interests via recommendations in Feed, Explore, and Reels." The effect for a store is that posting into a tag no longer places you in front of a standing subscribed audience, because there isn't one any more.
What should I write in a caption instead?
The words a customer would type. Lead with a first line naming the product specifically, use concrete product language ("machine washable" rather than "effortless elegance"), and add three to five accurate tags. On video, say the same words aloud and put them on screen — both platforms treat audio and on-screen text as evidence of what the content is about.
Are branded hashtags worth it?
Yes, as a collection point rather than a growth tactic. A branded tag groups your own posts and any customer content using it, which is genuinely useful for gathering UGC and running campaigns. It won't put you in front of new people by itself.
Should I use trending hashtags?
Only if they're actually relevant. An unrelated trending tag tells the recommendation system your video is about something it isn't, so it gets shown to uninterested people who scroll straight past — and both platforms rank on watch behaviour. You end up supplying evidence that your content doesn't hold attention.
Does putting hashtags in the first comment still help?
It was never established that it helped, and the December 2025 cap makes the question mostly moot on Instagram — the point of the comment trick was to hide a large block, and large blocks aren't available. Put a small number of accurate tags in the caption where they read naturally.
