How to Use Hashtags on Instagram Today, Honestly
An honest guide to Instagram hashtags today, what they can and cannot do, how to choose a few relevant ones, and why plain keywords now matter as well.
Short answer: Hashtags on Instagram still have a real but limited role: they help describe and categorise a post, and they can occasionally help people find it through search. They will not rescue weak content or grow an account on their own. Use a small number of specific, relevant hashtags, and put the plain words your audience searches for in your caption, name field and on-screen text as well.
Hashtags were once treated as the main discovery lever on Instagram. Today, discovery is widely observed to depend much more on how people respond to the content itself, and on recommendations that go beyond hashtags. That does not make hashtags useless. It makes them one small, tidy part of how you label your work.
Do hashtags still work on Instagram?
They work, but in a narrower way than many older guides suggest. A realistic view:
- What hashtags can do: signal the topic of a post, group it with related content, and make it findable by people who browse or search that tag.
- What hashtags cannot do: compensate for a weak hook, poor visuals or content nobody wants to save or share.
- What varies: how much reach a hashtag contributes differs by account, niche and period, and the platform adjusts its systems over time.
If you are deciding where to spend your effort, the content, the first line of the caption and the format choice usually deserve more attention than hashtag research. Hashtags are a finishing step, not a strategy.
How many hashtags should you use?
Instagram's Help Center currently says you can use up to 5 hashtags on a post. Limits have changed before, so check that page if the app behaves differently. Within that limit, fewer and more relevant is the sensible default.
A practical approach is to use a handful of hashtags that describe the post accurately. Adding many loosely related tags tends to blur the topic rather than sharpen it, and a long block of hashtags can make a caption look less considered to the people reading it.
How do you choose the right hashtags?
Pick hashtags the way you would pick labels for a filing system. For each post, choose from three layers:
- Topic: what the post is about (your content pillars are a good starting list). Example: #sourdoughbaking rather than #food.
- Audience or context: who it is for or where it applies. Example: #homebakers or #smallbakery.
- Your own tag, if useful: a branded or series tag that helps people find related posts from you. Example: #bakewithmaya.
Before adding a hashtag, open it in the app and look at the recent posts. Ask three questions:
- Are these posts genuinely about the same topic as mine?
- Would the people browsing this tag want to see my post?
- Is the content there appropriate and active, rather than spam?
If the answer to any of these is no, skip it. A tag that is huge but vague, or small but unrelated, adds little.
Why do keywords matter as much as hashtags now?
Instagram search looks at more than hashtags. Instagram's creator guidance recommends relevant keywords in your captions, bio and hashtags, and plain words in captions, the name field, the bio and on-screen text all appear to help people find content, although the exact weighting is not documented and can change.
In practice, that means writing the way people search:
- Caption: use the natural phrase. "How to keep sourdough fresh" is clearer than a string of tags. Our guide to captions people save shows how.
- Name field: a short descriptor next to your name, such as "Maya | Sourdough Tips". Our guide to an Instagram bio that converts covers this in more detail.
- On-screen text: a clear title on the first frame of a Reel or the cover of a carousel.
- Alt text: describe the image accurately. It helps accessibility first, and it gives the platform another plain description of the content.
Keywords and hashtags are not competing choices. Keywords describe the post in human language, and hashtags label it in platform language. Use both, lightly.
Where should hashtags go, caption or comments?
Instagram's Help Center confirms you can add hashtags in the caption or in a comment, and that a post from a public account appears on the hashtag's page. There is no strong public evidence that one reliably outperforms the other. The caption is the simpler and more transparent choice, because the hashtags stay attached to the post and are visible to anyone who reads it.
A clean format is to finish the caption with the call to action, add a line break, then list your few hashtags on a single line. It keeps the caption readable and the tags easy to find.
What hashtag mistakes should you avoid?
A quick checklist:
- Copying the same block onto every post. Each post should get tags that describe that specific post.
- Using broad tags only. Very general tags rarely describe anything useful.
- Tagging topics the post does not cover. It confuses readers and adds no value.
- Using tags you have not checked. Some tags are dominated by spam or unrelated content.
- Expecting hashtags to fix reach. If posts are not reaching people, look at hooks, formats and consistency first. Our guide to reading Instagram Insights helps you find where the drop happens.

Frequently asked questions
Should I stop using hashtags on Instagram?
There is no need to stop. A few relevant hashtags cost little and can help categorise your posts. Just avoid spending more time on hashtag research than on the content itself.
Are banned or restricted hashtags still a concern?
Some hashtags have had their results limited in the past, usually because of spam or policy issues. Checking a tag's recent posts before using it is the simplest precaution. If a tag shows few or no recent results, choose another.
Do hashtags help Reels more than carousels?
There is no reliable public evidence that hashtags work very differently by format. The same principle applies to both: describe the post accurately, and let the content do most of the work.
Should I create a branded hashtag?
A branded hashtag is useful when you run a series or want customers to share their own posts about you. It is unlikely to bring discovery on its own. Use it for organization and community, not as a growth tactic.
