Instagram Hashtags in the Caption or the First Comment?

Few Instagram questions cause as much debate as where to put your tags. Some people paste them at the bottom of the caption. Others post them in a comment straight after publishing. If you are deciding between hashtags in the caption or first comment, you are not alone, and the honest answer is that nobody outside the company can prove one is better.

If your question is a little different, these guides cover it: How Many Hashtags Should You Use on Instagram in 2026?.

This guide explains both options, what is known and what is unclear, and how to run a small fair test on your own account. We do not promise any change in reach. The goal is to help you pick a layout that looks tidy, is easy to maintain and fits the current rules.

What the two options look like

In the caption. You write your caption, then add your hashtags at the end, either straight after the last sentence or after a line break. They are part of the post itself.

In the first comment. You publish the post with a clean caption, then add a comment containing your hashtags. Some people do this to keep the caption looking neat.

Both are common. Instagram allows hashtags in either place. What is less clear is whether the location changes how the post is understood or shown, and that is the part people argue about.

What we can say, and what we cannot

Here is what is reasonably clear, phrased cautiously as of this writing:

• Instagram has said hashtags can be placed in a caption or in a comment.
• In December 2025 Instagram announced that it would gradually limit captions on posts and reels to 5 hashtags, and its Help Center page on using hashtags says you can use up to 5 on a post.
• Instagram has advised fewer, more targeted hashtags rather than many generic ones.
• Instagram has said hashtags group content by topic and matter less for reach than they once did.

And here is what is unclear:

• Whether hashtags in a first comment help a post in any measurable way. This is unproven.
• Whether the 5-hashtag limit may apply to comments as well. It might, so do not assume comments are a loophole.
• Whether the rollout looks the same for every account, since it was described as gradual.

Because rules change, confirm the current position in the Instagram Help Center before you build a routine around either method.

Pros and cons of hashtags in the caption

Pros

• They are attached to the post, so there is nothing extra to remember after publishing.
• You can edit them with the caption if you change your mind.
• Your caption, keywords and tags sit together, which makes the topic of the post easy to see.
• It is the simplest method, with fewer steps and fewer chances to forget.

Cons

• A long block of tags can make a caption look cluttered.
• If you use too many, you may run into the limit.
• The tags can distract from your message if they sit in the middle of the text.

With a limit of 5, the clutter problem shrinks a lot. A handful of tags on a final line looks tidy.

Pros and cons of hashtags in the first comment

Pros

• The caption stays clean and focused on your words.
• Some people find it easier to keep a saved list of tags and paste it.

Cons

• It adds an extra step every time, and it is easy to forget.
• There is no clear public evidence that it improves discovery.
• The limit may apply to comments too, so it may not save you anything.
• Your comment can get buried if the post attracts many replies.

If you are choosing hashtags in the caption or first comment based on convenience, that is a fair reason. If you are choosing the comment because you hope it unlocks extra reach, treat that as a guess, not a fact.

Which should you choose?

For most small accounts, the caption is the sensible default. It is simpler, it keeps everything in one place and it does not depend on an unproven benefit. Keep your tags to a small, specific set that matches the topic.

The comment option can make sense when you care a lot about how the caption looks, for example on a design or photography account where the written text is part of the brand. Even then, test it first.

It runs in your browser and sends nothing to a server. It does not know live search volume, so use it to generate ideas, not to measure demand.

Worked example: a hypothetical two-week test

This is a made-up illustration, not a real account and not a real result. Imagine a small pottery account that wants to know whether to use hashtags in the caption or first comment.

Setup. The account posts four times a week. It chooses two post types of similar kind, such as studio process photos, so the comparison is fair. It picks five specific hashtags and keeps them the same throughout.

Steps.

1. Weeks one and two: put the five hashtags in the caption on every post.
2. Weeks three and four: remove them from the caption and post them in the first comment instead.
3. Keep everything else steady: posting days, time of day, type of content and caption style.
4. After each post, wait the same amount of time, for example three days, and note reach, saves and shares from Insights.
5. Compare the two periods and look for a clear difference.

Summary of the hypothetical test: same tags, same post type, same timing, with only the location changed. If the numbers look similar, the account can choose whichever layout is easier to maintain. Four weeks of small-account data is rarely conclusive, so the result should be treated as a hint only.

How to test fairly on your own account

A fair test changes only one thing at a time. These habits help:

• Keep the content similar. A reel and a photo should not be compared with each other.
• Use the same tags. If you change both the tags and the location, you will not know which mattered.
• Allow enough time. One post proves nothing. Several posts over a few weeks give a clearer picture.
• Record your results. A simple spreadsheet with date, location and metrics is enough.
• Expect noise. Reach varies for many reasons that have nothing to do with hashtags.

Instagram Insights shows metrics such as reach, saves, shares, likes, comments and profile visits, although menu names change. Our article on reading Instagram Insights explains what each one means.

Mistakes to avoid either way

• Using more tags than the current limit allows.
• Choosing generic tags such as #reels or #explore, which Instagram has advised avoiding.
• Copying the same block of tags onto every post, even when the topic changes.
• Putting tags in the middle of a sentence where they interrupt reading.
• Hiding spam-like tags in a comment and hoping nobody notices.

Our guide to Instagram hashtag mistakes covers more of these in detail.

Frequently asked questions

Do first-comment hashtags work as well as caption hashtags?

That is unproven. Instagram has said hashtags can be placed in a caption or a comment, but we are not aware of public evidence that one is better. Test it on your own account and check the Help Center for current guidance.

Can I put 5 hashtags in the caption and 5 more in the comment?

We would not rely on that. The 5-hashtag limit may apply to comments as well, and rollout details can differ between accounts. Check the Help Center, and remember that fewer, more targeted tags is what Instagram has advised.

Should I delete old posts that have lots of hashtags?

There is no need to remove them just because of the new limit. Focus on using a smaller, relevant set on new posts. If you want to tidy an older caption, you can edit it, but this is optional.

Conclusion

On the question of hashtags in the caption or first comment, the honest summary is this: both are allowed, no public evidence proves the comment is better and the caption is simpler. Keep your set small and specific, avoid generic tags and do not treat the comment as a way around the limit.

Your next step is to pick one method for the next two weeks, record your Insights and compare. Confirm current hashtag rules in Instagram's official Help Center before you start.
