How many Instagram hashtags can I use in 2021?

Instagram lets you add up to 30 hashtags – but that doesn’t mean you should.

Or should you?

Truth is, there’s no right or wrong answer. You can find a study that backs every idea from using 1-3, through to all 30.

But here are a few of the top studies to help you decide what to try.

Posts by brands have few hashtags

One study from Sprout Social found that the posts by brands that performed best had just 1-3 hashtags in them.

Most brands use 2-5, and the success of the post trails off when using 10 or more.

But the picture was a little different when the metric measured was engagement rather than reach.

Here, using 7-15 hashtags seemed to work best.

Posts with 9 scored the highest engagement per post. Their study did stop at 15 hashtags.

Below, we’ll examine an older study which found that posts with 11 or more hashtags get the best engagement.

This study found that posts with:

• 0 Hashtags received only 18% interaction per 1k followers
• 1 Hashtag got 29% interaction per 1k followers
• 2 Hashtags enjoyed 41% interaction per 1k followers
• 3 Hashtags had 39% interaction per 1k followers
• 4 Hashtags dipped a bit to 31% interaction per 1k followers
• 5 Hashtags received 43% interaction per 1k followers
• 6 Hashtags got 33% interaction per 1k followers
• 7 Hashtags had 30% interaction per 1k followers
• 8 Hashtags saw 39.5% interaction per 1k followers
• 9 Hashtags did well with 49.5% interaction per 1k followers
• 10 Hashtags saw the worst engagement at 22% interaction per 1k followers
• 11 Hashtags enjoyed the best engagement at 79.5% interaction per 1k followers

Using 11 or more hashtags means 442% more engagement that using none, and about double engagement over using 1 – 10.

So I recommend using at least 11, and more if you want to grow your account.

How many followers you have can help decide

Another study by Social Insider looked at the number of posts and how many followers.

Now this study was from 2019, which may be a good thing. 2020 was something of an outlier when it comes to internet data.

That means this 2019 study could still be worth factoring in.

They found that:

• Accounts with under 5K followers did best with 6 hashtags in the caption
• Accounts with 5-10K following did best with 5 hashtags in the 1st comment
• Accounts with 10-50K following did best with 2 hashtags in the post
• Accounts with 50-100K following did best with 8 hashtags in the post
• Accounts with 100K+ following did best with 6 hashtags in the 1st comment

Test it and see

Confused? No surprise there, it is clear that even Instagram doesn’t know where the sweet spot is.

Many bloggers who specialize in Instagram just go for the full 30 hashtags because that gives you the most exposure possible.

A lot depends on how many super-relevant hashtags you can find.

Then test! Try a few different combinations and track your analytics to see which ones work best. After all, what works with your audience is ultimately the most important thing.

Is there a maximum of hashtags on Instagram?

The maximum allowed Instagram hashtags is 30. I recommend you use them all – unless you’re happy with your follower number and engagement.

Want to grow? Use 30 hashtags!

What’s the hack to use 60 hashtags on Instagram?

There used to be a trick where you could first post 30 hashtags in a comment, then go back and edit the photo caption to add 30 more hashtags.

Instagram didn’t notice the hashtags in the caption edit, so you could effectively post a total of 60.

They caught on in 2018, though. So the maximum is 30 Instagram hashtags in 2021.

Should I post Instagram hashtags in comments or caption?

Instagram hashtags may be placed in the photo or video caption at the time you post.

Or, hashtags may be added in a comment (or several comments) after posting.

There’s no difference to their functionality, so it’s your choice.

I prefer adding hashtags in comments, as these are quickly buried once you get a few user comments.

Starting in 2018, the caption is cut off after 2 short lines of text, so caption hashtags don’t show at first glance either.

However, IGers clicking either the “More” tag or the comment icon will see the full caption – including all the hashtags you placed there.

If you’ve written an engaging caption with a call-to-action or question (please do!), people may get distracted by a raft of hashtags and forget to complete your desired action.

This is why I recommend Instagram hashtags in comments rather than captions.

How to hide hashtags on Instagram

You can hide those 30 hashtags, so they can’t look spammy!

Make them invisible by preceding them with five dashes or periods, each one on a line by itself.

NO space after the period or it won’t work. If you post this in your first comment, IGers will just see […] after your name in the photo stream.

(Tested 1/11/2020 – it still works. The hashtags are only invisible in the photo stream! If someone clicks to read comments, they will see the hashtags).

Create your hashtag text file as I show below, in your phone’s Notes app, because there’s no return key when posting a comment in Instagram.

NOTE: If you’re having problems with this trick, it’s almost always because you have a space at the end of your line. It’s a bizarre and annoying quirk, but Instagram will take out the return if there’s a space at the end of the preceding line.

If you’re confused on whether to hide hashtags in a comment or caption, and which actually works better, do a split test! You can do this manually, or for easier comparing, use Tailwind.

Tailwind makes setting up either way easy. Schedule your posts, then automatically publish them to your business account.

Try a week each way, then check Tailwind’s fabulous analytics to see which worked better for you.

Can I add hashtags to someone else’s Instagram photo?

No. You can’t add working hashtags by commenting on any other account than the one you’re signed into.

Anyone can comment on someone else’s post with hashtags, but the other IGer’s post won’t appear in that hashtag feed.

If you see people leaving hashtag comments on others’ posts, they may be suggesting that the original poster add that hashtag.

A little helpful advice, perhaps.

Or, they may not know. But generally I see these hashtag comments between groups of IG friends who are helping each other get featured on Instagram hub accounts.

What are the most popular hashtags on Instagram for 2021?

There’s no surprise that with 2020 being the weird year that it was, most popular hashtags were a little different.

For example, the most popular hashtags of all time (according to Later’s data) are:

1. #love
2. #instagood
3. #photooftheday
4. #fashion
5. #beautiful
6. #like4like
7. #picoftheday
8. #art
9. #happy
10. #photography
11. #instagram
12. #followme
13. #style
14. #follow
15. #instadaily
16. #travel
17. #life
18. #cute
19. #fitness
20. #nature

But the top 20 hashtags for 2020 reflect how we were thinking and acting during that year:

1. #beach
2. #l4l
3. #blogger
4. #instadaily
5. #lol
6. #blue
7. #instagram
8. #model
9. #nature
10. #hot
11. #followme
12. #pink
13. #bestoftheday
14. #night
15. #blackandwhite
16. #nofilter
17. #food
18. #f4f
19. #family
20. #foodporn

In 2021, things are normalizing a little. But some of these top 2020 hashtags will still be relevant.

Maybe a mixture of classic and 2020 top hashtags where suitable might be worth testing.

Here are the 10 best Instagram hashtags for likes, according to All Hashtag, an Instagram analytics tool:

1. #like4like
2. #liking
3. #likeall
4. #likeforlike
5. #likes4likes
6. #love
7. #instagood
8. #tagblender
9. #likesforlikes
10. #ilikeback

However – just because these work for the “average” account doesn’t mean they’ll work for yours.

I suggest you get a little more creative with your hashtags. Read on…

Should I use popular Instagram hashtags?

If you’re using 30 hashtags, okay, go ahead and make 1 or 2 of those popular ones.

This will get you some quick likes. However, most of those will be fake, bot likes.

Yes, automated “bot” activity is still a problem on Instagram in 2021.

Use popular tags, and you’ll likely also be the target of annoying follow-unfollow activity.

This is where those rule-breaking IGers use automation to follow accounts they think might follow them back.

If you don’t follow back, and sometimes even if you do, they’ll unfollow you anyway.

Don’t take it personally, as it’s all automated. No one is making any judgement of your account.

Please don’t ever do automated follow-unfollow on Instagram. You risk your account being shadowbanned or even closed.

But back to those popular tags, they may work for likes in the first second after you post. Your post will be quickly buried in the hashtag feed.

In addition, popular hashtags are often used by spammers and quickly get banned!

Using banned hashtags may put you in league with spammers and arouse Instagram’s suspicions about your account.

Banned Instagram hashtags 2021

So now you want to know: which hashtags are banned by Instagram?

Unfortunately this is an ever-moving target. According to Markitors.com:

… the hashtag #happythanksgiving was completely overrun with spam, so they banned it. From here on out, if you use the hashtag #happythanksgiving, not only will your content most likely not show up for that hashtag, you might also be flagged for spam. The repetitive use of banned hashtags, leading to multiple flags to your account, could even result in shadow banning or account removal.

Of course, in order to avoid these forbidden hashtags, you have to know which tags are banned. How is anyone supposed to know that #happythanksgiving is considered “spam”?

There are 3 ways to avoid using banned hashtags:

1. Don’t use any of the most popular Instagram hashtags.
2. Research any hashtag before using it.
3. Use Tailwind Hashtag Finder. NO banned hashtags are ever included.

To research currently banned tags, search for a specific hashtag in the search bar.

Click on the hashtag and scroll through the pictures.

If you reach an end where a message says the posts are “currently hidden,” it’s a banned hashtag.

What are the best Instagram hashtags?

I don’t recommend popular tags, for the reasons stated above.

Here’s what I do recommend:

Use hashtags that are relevant to your niche.

Using specific and relevant hashtags helps you connect with people who are looking for exactly what you’re posting.

You can find relevant tags by searching your keywords in Instagram, or using a site like Hashtagify.me.

Watch what others in your niche are using.

See what your peers and influencers are posting on their photos.

Check out the related tags Instagram suggests when you tap a tag that’s relevant to your content. Try them if they seem useful!

Be sure your hashtags are active.

Check the hashtag feed to see that the tags you’re using are currently being used by others.

Hint: If you scroll down 20 rows and are still finding content posted in the last few seconds, that tag is too active!

Stop using the most popular hashtags like pretty, beautiful, love and similar ones.

Your post will be buried in that feed within milliseconds. In researching this, I also discovered a lot of posts in those tags that I don’t even want to be seen with (some I even felt obligated to report).

Okay, sprinkle in a few popular hashtags when relevant to your post.

Not necessarily the ones with 100M’s of posts, but one or two over 1M might give you some quick likes.

Note: Your content really needs to be awesome to stand out in a lighting-fast moving tag feed!

Create a custom tag for your brand or campaign.

Check that these tags aren’t already being used, particularly in a way you wouldn’t approve of!

Prompt fans and followers to use your tag, and you’ll soon learn just who your superfans are. Support, encourage, and regram them!

Can I add hashtags to Instagram after posting?

Once upon a time, using hashtags was easy:

• You posted a bunch with your photo.
• You came back later, deleted those tags, and added a bunch more.
• Magically, your post was bumped to the top of those hashtag feeds, regardless of how long it had been since the original post.
• Your engagement spiked once again.

But Instagram changed all that for us in March 2015.

No matter when you add a hashtag to your photo or video, it will appear in that hashtag feed with other photos and videos posted at its original posting time.

Or as Instagram says:

Keep in mind that if you add a hashtag to a photo after it was posted, the photo will still appear on the hashtag page according to the time it was originally posted, not the time the hashtag was added.

The short answer is yes, you can add hashtags to your own posts after posting.

Popular hashtags must be added immediately, or your post will never surface in those feeds.

If you like, you can delete those later and add niche hashtags in their place.

Personally, I think your time is better spent on creating new Instagram posts.

Why are my Instagram hashtags not working?

You may be the victim of a shadowban.

A shadowban hides your Instagram posts from users who don’t follow you, which can be detrimental to growing your account and getting more followers.

If you get shadowbanned on Instagram, only you and your current followers will see your post when they search for the hashtags you used. If someone who doesn’t follow your account searches for one of those hashtags, they won’t see your post!

This defeats the purpose of using strategic hashtags to grow your Instagram community.

I’ve even had readers say they can’t find their own posts in the hashtag feeds! This could also be due to shadowban. Or, as IG calls it, “issues with hashtag search.”

Instagram doesn’t admit there is such a thing, by the way, so don’t expect to get help from them.

You can use the “Report a Problem” feature in your account settings under “Support.” I no longer get a reply when I do this, but it can’t hurt.

I would suggest saying “my post isn’t showing in the hashtag feeds” and not use the word “shadowban.”

How can I avoid being shadowbanned?

Instagram shadowbanning is sometimes a result of spammy behavior.

However, some normal behavior is also getting users shadowbanned:

• Repeated use of the same hashtag group within 24 hours.
• Using “broken” or banned hashtags.

Sometimes a normal, everyday hashtag can be banned.

Popular tags are often used on content that violates IG community guidelines. Then Instagram might block the hashtag outright, meaning you can’t even search for it on IG, or they’ll limit the posts shown in that hashtag feed.

With the shadowban, it appears that even if you use a single banned hashtag in your post, Instagram will prevent your post from appearing on any of the hashtags you used!

So, you could search each hashtag feed individually for evidence that a tag is broken or banned. Don’t use those!

OR, just make your life easier by using Tailwind’s Hashtag Finder!

It will give you fresh, related choices so you’re not repeating the same hashtag group, and it will only suggest tags that are Instagram-approved!

How to post Instagram hashtags for best results:

If you insist on using uber-popular hashtags, you MUST post them in your post caption.

If you wait even a second to post them in a comment, they’re pretty much worthless, as your post will be buried in that hashtag feed the instant you add it.

If you post hashtags in several comments, post the more popular ones first. 

Post hashtag comments in the order of how fast the hashtag feeds move!

Niche hashtags CAN still be added at a later date!

DON’T bother adding hashtags where the original date of your post would have it buried deeply in the feed – BUT there are some cool super-niche hashtags that have only several hundred to a few thousand posts in them. Many of these even have avid fans!

For easiest hashtagging, keep groups of 30 hashtags in your phone’s Notes app.

Create and save a set of 30 tags for each type of post you make (or less than 30 if you insist 😉 ).

Copy your hashtag group before you make your IG post!

Then you have them ready on your clipboard to add in a comment immediately. No fumbling, no wasting valuable seconds. Or, set up a text shortcut!
