How to find trending hashtags on Instagram, and check they suit you
How do you find trending hashtags on Instagram? Start from what is moving in your own corner of the app: the Reels and Explore tabs, the tags on recent posts that are doing well in your niche, and the tags your competitors keep reusing. Then open each candidate’s hashtag page and check that its newest posts really are new. Instagram does not publish a trending hashtags list, so every method is a way of collecting candidates and then confirming them. This guide walks through both halves, and then the part most guides skip: deciding whether a trending tag is any use to you.
Why there is no trending hashtags list to copy
The first thing most people search for is a list. Plenty of sites publish one, and it is tempting to paste the top ten under your next post.
The trouble is that a trend is local and short-lived. What is trending for fitness creators this week has nothing to do with what is trending for bakeries, and a list written last month describes last month. A generic list also points everyone at the same few tags, so your post lands in the busiest pages on the platform, where it scrolls out of sight in minutes.
Treat any published list as a set of candidates, never as an answer. The work that matters is confirming each candidate for your audience, today.
How to find trending hashtags on Instagram, step by step
Here is the whole job, using nothing but the app. It takes about twenty minutes the first time and less once you have a routine.
- Collect candidates from Reels and Explore. Scroll both tabs for a few minutes while logged into the account you post from. Instagram fills them with what is active for interests like yours. Each time a topic repeats, open the post and note the tags in its caption.
- Collect candidates from your niche’s best recent posts. Visit five to ten accounts that post what you post. Look at their posts from the last week that clearly did well, and note the tags. A tag that turns up on several of them is live for your audience.
- Collect candidates from your competitors. The same exercise on direct rivals shows which tags they are betting on right now. Our guide to Instagram competitor hashtag analysis goes further on this.
- Search each candidate. Type it into search and open the hashtag page. If you have not done this before, how to search hashtags on Instagram covers the steps on the phone and on the web.
- Check how recent the posts are. A trending tag has posts from the last hours or days on its page. If the newest posts you can find are weeks old, the tag is quiet, whatever a list says.
- Check who is posting. This is the step that decides whether a trend is yours. Customers, peers, sellers like you, spam accounts: write down which.
- Keep the few that pass both checks. Recent posts and the right people. Everything else goes.
That loop is the answer to the question. The rest of this guide is about doing it well and doing it faster.
Where trends show up in the app
Each place you look shows a different kind of trend, so it helps to know what you are seeing.
| Where you look | What it tells you | What it misses |
|---|---|---|
| Reels tab | Formats, sounds and topics that are spreading fast | Slower, steady tags that still bring the right readers |
| Explore tab | What Instagram thinks your account is interested in | Anything outside those interests |
| Niche accounts’ recent posts | Tags that work for your exact audience | Tags nobody in that circle has tried yet |
| Competitors’ posts | Tags your rivals are betting on now | Whether those bets are paying off |
| A hashtag page itself | Whether a tag is live right now | How the tag compares with the others on your list |
The Reels tab is the fastest signal and the least specific one. It shows what is spreading everywhere. Niche accounts are slower to read and far more useful, because they show what is spreading among the people you actually want to reach.
How to tell a trending tag from a busy one
A busy tag is not the same thing as a trending one, and neither is automatically good for you.
- Busy means lots of posts go up under it all the time. Big generic tags are always busy. Your post has to compete with all of them and usually vanishes quickly.
- Trending means activity under it has picked up recently. A trending tag can be small. That is often the best kind, because it is active and not yet crowded.
- Useful means the people posting and browsing under it are the people you want. This is the only test that decides anything.
A practical way to judge the first two by hand is to open the hashtag page on two days a week apart and compare. If the recent posts look noticeably newer and more frequent the second time, the tag is picking up. If the page looks the same, it is steady. If the newest posts have got older, it is fading.
A simple note keeps these checks consistent across a list:
| Column | What to write |
|---|---|
| Tag | The exact spelling, since plural and singular are different tags |
| Newest post | Hours, days or weeks old |
| Compared with last week | Picking up, steady or fading |
| Who posts there | Customers, peers, sellers, spam, or a mix |
| Keep? | Yes, no or maybe |
Checking a trend fits your account
Jumping on a trend that has nothing to do with your posts rarely helps. The people browsing that tag came for something else, and they scroll past.
Ask three questions of every trending tag that survived the checks above:
- Would someone browsing this tag want to see my post? If you have to stretch to say yes, leave it out.
- Is the tag clean? Open the page and look properly. A tag Instagram has limited, or one taken over by spam, does nothing for you. Instagram also keeps a help article on why some hashtags cannot be searched, and a tag that behaves like that belongs off your list.
- Does it earn one of my few slots? Instagram caps how many hashtags a post can carry, so each tag on a post has to beat the others. Best hashtags for Instagram covers building a balanced set within that limit.
A small trending tag your customers use beats a huge one they do not. That is true on every platform, and more so when you only have a handful of tags per post.
Finding trending hashtags faster
The manual loop works. It gets slow when your list grows past a dozen tags, when you want to repeat it every week, or when you have to explain your picks to a client or a manager. The part that eats time is not the searching. It is deciding what to look at and keeping the checks consistent from one week to the next.
That planning step is the job Hashtag Ninja is built for. You describe what you want to know in a sentence, for example “which tags are picking up among home bakers in Leeds this month”, and the free planner turns it into a collection plan: the tags to look at, how many posts to pull per tag, over what window, and what to look for in them. It also lists the assumptions it made, so you can correct a guess (the wrong city, the wrong kind of baker) before relying on the plan. It needs no signup, and you can copy the plan out as plain text.
To be straight about what it does today: turning a plan into a report, with the posts themselves, the numbers computed from them and a CSV, is open, on the 500 free rows a signed-in account gets every 30 days. The pricing page says what that will cost and what state it is in. The plan on its own is still useful for this job, because it is the candidate list and the checklist you would otherwise build by hand in step one.
If your question is more specific than trends, there is a page that starts from it:
- Instagram hashtag research for sizing up the tags a niche uses
- Find micro-influencers by hashtag when a trend is really a question about who is posting
- Instagram brand mention tracking when the tag you care about is your own
Manual checks compared with a planned approach
| Task | By hand in the app | With a written plan |
|---|---|---|
| Spot what is moving | Scroll Reels and Explore | Describe your niche in a sentence |
| Build a candidate list | Notes from posts and rivals | Listed in the plan |
| Decide what to check per tag | Up to you, each time | Written down, with its assumptions |
| Repeat next week | Start the loop again | Re-use the same brief |
| Explain your picks | Screenshots and memory | Share the plan text |
Neither way sees posts from private accounts. Instagram keeps those off hashtag pages, so every method, manual or not, is judging the public part of a tag.
When the manual way is enough
You do not need anything beyond the app if:
- you post a few times a week and mostly reuse a set of tags you already trust;
- you want to test one trending tag before adding it to that set;
- your niche is small and you already follow the accounts that set its trends.
In those cases, run the seven steps, keep the one or two tags that pass, and move on. Checking once a week is plenty for most small accounts.
A plan earns its place when the list is long, the check repeats every week, or somebody else needs to see why you picked what you picked.
A short routine you can keep
- Once a week, spend ten minutes on Reels, Explore and your niche’s best recent posts, and write down repeat tags.
- Open each new candidate’s page and note how recent the newest posts are.
- Compare with last week’s note: picking up, steady or fading.
- Keep only tags where your customers are posting.
- Swap one tag on your posts at a time, so you can tell what changed.
That is how to find trending hashtags on Instagram that are worth using. Lists tell you what was popular somewhere. A weekly check tells you what is moving for your audience now.
