Hashtags used to be one of the main ways people found content on Instagram. Today they're a small labeling tool: they help Instagram and viewers understand what a reel is about, and that's most of what they do. Here's how to handle them in two minutes per post, and where your effort pays off more.
What hashtags do for Reels now
Think of a hashtag as a label on a box. It describes what's inside, but it doesn't deliver the box anywhere.
What they still do:
- Add a topic clue. Instagram looks at many things to understand a reel, including the caption, text on screen, the audio, and the video itself. Hashtags are one more clue.
- Make the reel findable on a hashtag page. Tapping or searching a hashtag shows posts that use it, so a specific tag can bring in a few viewers who are actively interested.
- Group your own content. A branded or series tag lets people tap through your related posts.
What they don't do:
- They don't guarantee reach. Reels mostly reach people through recommendations, which depend largely on how viewers respond: whether they watch, rewatch, share, save, or swipe away. Instagram has been open that hashtags play a minor role in how far a post travels.
- They don't reach "hashtag followers." Instagram removed the option to follow hashtags, so a tag no longer pushes your reel into anyone's feed.
- They don't fix a weak opening. No tag will save a reel people abandon in the first few seconds.
How many hashtags to use
For years the limit was 30 per post, and plenty of people used all 30. Instagram has since moved toward a much lower cap, so check what the app allows when you post. Exact limits change, and the app will tell you if you've added too many.
Whatever the current limit, 3–5 relevant hashtags is a sensible target. Each one should describe the reel accurately. Past five, you usually start reaching for tags that are only loosely connected, which add clutter without adding meaning.
Put them in the caption, not a first comment. The caption is part of the post itself, while a first comment can get buried as replies come in. Add them at the end of the caption, or work one or two into a sentence if it reads naturally.
Choose specific tags over broad ones
Broad tags like #food or #fitness are attached to an enormous number of posts. They're so general that they tell Instagram almost nothing, and your reel will be buried on the hashtag page within minutes.
Specific tags work better because they describe the reel precisely and attract people who want exactly that. Mix these types:
- Topic tag: the subject in plain words, such as #doggrooming.
- Niche tag: the specific version, such as #doodlegrooming or #handstripping.
- Local or audience tag: essential for local businesses, such as #leedsdoggroomer or #newpuppyowners.
- Branded or series tag (optional): your business name or a recurring series, such as #fridayfloofs.
So a dog groomer in Leeds posting a before-and-after might use #doggrooming #doodlegrooming #leedsdoggroomer #fridayfloofs. Four tags, each one accurate.
Vet a tag before you use it
Tap any new hashtag and scroll its page for ten seconds. Ask:
- Are the posts recent and similar to what you make? Good fit.
- Is it full of spam, giveaways, or unrelated content? Skip it.
- Does the page show a notice that recent posts are hidden, or look strangely empty? The tag may be restricted. Pick another.
Keywords now do more work than hashtags
People increasingly search Instagram the way they search the web, typing phrases like "easy sheet pan dinner" or "small bathroom makeover" rather than hashtags. That makes your words, in the right places, more useful than your tags.
Put the keyword in your caption's first line
Write the first line the way someone would search for it. "3 easy sheet pan dinners for busy weeknights" is clear to viewers and to search. "Dinner tonight was a vibe" is neither. Keep the rest of the caption natural; you don't need to repeat the keyword five times.
Repeat it on screen
Add a short text title in the first second or two that uses the same words: "Sheet pan dinner in 20 minutes." It doubles as a hook, helps people watching with the sound off, and gives Instagram another clear signal about the topic. Our guide to captions and subtitles on Reels covers how to keep on-screen text readable.
Say it out loud
If you talk in the reel, name the topic in your first sentence. Spoken words show up in auto-generated captions, and they make the point clear to viewers immediately.
Use the name field on your profile
The Name field (separate from your @username) is searchable. "Priya | Wedding Florist Austin" will turn up in more searches than "Priya" alone. Instagram limits how often you can change your name, so choose carefully.
Public posts from professional accounts may also appear in outside search engines, depending on your settings, so clear captions can help there too.
What to stop doing
If any of these are part of your routine, you can drop them and lose nothing:
- Pasting the same 30-tag block on every post. It reads as spammy, and most of those tags won't describe the reel anyway.
- Using tags that describe nothing. #reels, #viral, #explorepage, #instagood, and #fyp tell Instagram nothing about your topic.
- Adding trending tags that don't match your content. Riding a hashtag your reel has nothing to do with misleads viewers and can make your account look spammy.
- Hiding tags behind dots or line breaks. It neither helps nor hurts. Format the caption so it's easy to read and move on.
- Trusting hashtag generators blindly. They tend to suggest popular broad tags. Use them for ideas, then vet each one.
- Blaming hashtags for low views. If a reel underperforms, look at the hook, the watch time, and the topic first. Our list of mistakes that hurt Reels reach is a good place to start.
A two-minute hashtag routine
Use this every time you post:
- Write the caption's first line around one clear keyword phrase.
- Check that your on-screen title uses the same words.
- Pick 3–5 tags: one topic, one or two niche, one local or audience, and an optional branded tag.
- Tap any tag you haven't used before and vet it.
- Keep a starter set for each type of content you post in your notes app, then adjust it for each reel rather than pasting it unchanged.
To check whether your keywords are working, search your main phrase from a friend's account every few weeks and see whether your reels show up. That tells you more than guessing which hashtag brought in which viewer.
