[What Data Says] Do Instagram Hashtags Help with Post Impressions?

Last week, Adam Mosseri, the head of Instagram, said that Instagram hashtags don't "really" help with post distribution in one of his Stories.

This announcement generated a lot of fuss on social media, as social media specialists have to rethink their marketing strategies moving forward.

And like any other social media news that can dictate how social media professionals will shape their strategies in the future (in this case, Instagram hashtags strategies), it was discussed by many industry experts, such as Jenn Herman - Instagram expert, Allie Mason - Instagram expert and coach, or Matt Navarra - social media consultant.

While they all came to the same conclusion - that Instagram hashtags don't affect post views - we wanted to test this hypothesis with the help of data.

We analyzed 75,361,233 Instagram posts published between March 2021 and March 2022 to see whether Instagram hashtags play a role in post views, calculated as the average engagement rate by impressions.

Let's see what the data says! ๐Ÿ‘‡

A. Key takeaways

Here is what 75,361,233 Instagram posts tell us about hashtags for Instagram post distribution.

  • Instagram hashtags donโ€™t help with post views.

  • Big accounts should use three-four hashtags to obtain better impressions rates.

  • Mid-sized accounts get a higher impression rate if they use more than five hashtags.

1. How do hashtags impact Instagram post engagement?

In one of his recent Instagram stories, Mosseri answered a question from a user about whether โ€œhashtags help views.โ€

His answer was "not really."

Instagram hashtags don't increase post views on Instagram. Instagram hashtags are used to categorise content and make it discoverable for users.

The argument behind his response was that Instagram hashtags help users understand what a post is all about, but itโ€™s not necessarily a strategy for getting more distribution.

This new information, especially when coming from the head of Instagram, changes the whole social media scene, as social media specialists want to know how the platform works and how they can reach more people.

Mosseriโ€™s statement was further taken by Matt Navarra, social media consultant, and discussed in a poll on LinkedIn.

Interestingly, 53% of the respondents answered that the main reason for using Instagram hashtags is to boost reach/post views.

Matt Navarra discusses if Instagram hashtags influence post views in a LinkedIn poll.

While this makes sense to some extent, since Instagram hashtags help with content discoverability and organic searches (especially when they have a big following), usersโ€™ tendencies are not always reflecting how algorithms truly work.

Jenn also commented on this theory in one of her Instagram posts, and she takes it even further.

According to Jenn, there have been a lot of changes recently in how Instagram hashtags work.

Because Instagram is trying to change the platform into a search destination, they introduced keyword search.

Instagram keyword search works by allowing users to type in a keyword such as โ€œhome office inspirationโ€ rather than being limited to a hashtag like #homeofficeinspiration.

As a result, we see decreased Instagram hashtag performance because people are typing in a keyword/phrase, but theyโ€™re not navigating on the hashtags page as they did in the past.

So youโ€™re still getting post distribution, but youโ€™re not necessarily seeing it in the hashtag results.

Jenn strongly argues that hashtags still help Instagram place your content in keyword categories and help users get more exposure in the hashtag feed.

If you want to be successful on Instagram, you still need to use hashtags, but you need to use them strategically.

Jenn Herman talks about Instagram hashtags and post distrubution.

With all these discussions in the digital space, we wanted to test his hypothesis with the help of data.

After analyzing 75,361,233 Instagram posts published between March 2021 and March 2022, we came to the same conclusion.

This graphic shows that Instagram hashtags don't influence post views.

As the graphic suggests, the number of hashtags a post has doesn't really influence post distribution, which we calculated as the average engagement rate by impressions.

The data shows no significant differences in the average engagement rate by impressions of the Instagram posts analyzed, regardless of how many hashtags those posts have.

The highest average engagement rate by impressions (3.41%) is attributed to Instagram posts with three-four hashtags, which is in line with Instagram's recent recommendation to only use between three-five hashtags.

๐Ÿ“Œ So for your future Instagram hashtags strategy, you could try and test this by sharing posts with three-four hashtags and posts with more than five hashtags and see if there are any differences in reach rates.

2. How many Instagram hashtags should you use per post?

Because we wanted to go more in-depth in our analysis and make sure we're looking at equal comparisons, we decided to add one more pillar: the number of followers.

According to the data, there aren't significant differences in the average impressions rates of the Instagram posts analyzed concerning the number of hashtags and followers.

Depending on the size of your account, you should use three-four or five-six Instagram tags on average to maximize your chances of obtaining more post views.

Let's have a look at the graphic below. ๐Ÿ‘‡

This graphic shows how many Instagram hashtags to use per post.

The only noticeable trend is for the accounts with 50K - 1M followers.

The graphic shows that their impressions rates decrease as those accounts use more hashtags.

The best practice for big accounts is to post Instagram content with three-four hashtags to obtain an average engagement rate by impressions of 3.42%.

๐Ÿ‘‰ If higher accounts use more than four hashtags, they'll get a lower impressions rate.

For small accounts (5K - 10K followers), the trend is also slightly decreasing, but the differences aren't as evident as in the case of big accounts.

To increase their chances of scoring higher reach values, small accounts should include an average of five-six tags in their Instagram posts to reach an average engagement rate by impressions of 3.79%.

This also applies to mid-sized accounts (10K - 50K followers). They get a higher impressions rate (3.5%) if they use more than five hashtags.

So, to sum up the findings of these Instagram tags analyses, it's safe to say that the number of hashtags you use in your Instagram posts doesn't affect the posts' distribution.

This is one of Jenn Herman's quotes regarding hashtags for Instagram posts.

However, using hashtags as part of your Instagram strategy is still important, as they help with discoverability.

B. Methodology

For this analysis, we looked into 75,361,233 Instagram posts published between March 2021 and March 2022.

The Instagram profiles analyzed have the following base between 5K - 1M followers.

We split the graphic by followers count; we selected three intervals:

  • 5K - 10K
  • 10K - 50K
  • 50K - 1M

The average engagement rate per post (by impressions) on Instagram is calculated as the total engagement (likes and comments) divided by the number of posts the profile published. The result is then divided by impressions, and all multiplied by 100.

Impressions = the number of times your content is displayed.
