** DISCLAIMER: We re-tested in June of 2018 and will include those results at the very end of this experiment **
Are you like me?
I constantly try every method known to man in an attempt to get more people to see our content, engage with it and hopefully buy from us.
But most of the time the effort is futile and I’m just frustrated.
Luckily most of the social media platforms realize our pursuit for engagement and are constantly adding features to help us attain those goals.
Instagram is one of the best at this — and today I want to test a new feature called Instagram Carousels.
What are Instagram Carousels you might ask?
This is a feature Instagram released in early 2017 allowing users to upload a combination of 10 photos or videos to the app instead of just 1.
It’s a really cool feature and many users are finding creative ways to display their products with the Instagram Carousel. So instead of multiple posts to show an event, product, etc you can do it in 1 post with many photos.
This post for example from Sciencewows shows you how to make Rainbow Silly Putty just by swiping through the images.
The Dallas Cowboys posted a cool and cute one of players holding puppies on National Puppy Day:
The idea many marketers believe is that by posting an Instagram Carousel you’ll increase curiosity of users and get them to swipe through the images, Like them more, comment more, etc.
If they do that then your account is more likely to show up for users according to Instagram’s algorithm.
So that’s exactly what I want to test.
I asked this question in a VERY large Social Media Managers group and to my surprise 100% of those that responded thought Instagram Carousels would cause less engagement!
I think they are wrong!
Hypothesis: Posting an Instagram Carousel will result in an increase in engagement, primarily in Likes, as well as result in an increase in Impressions and Reach.
To get some data on Instagram Carousels I’ll be posting carousels on the @Agorapulse Instagram account as well as an account for my small, local business.
Both accounts regularly post to engage their active fans.
I’m also going to take a look at some popular Instagram accounts and gather some data to compare the engagement on their Carousel posts and regular posts.
On the Agorapulse account and my business account I’ll be able to see Impressions, Reach, Likes, Comments, and Engagement rate. For the other accounts that aren’t mine I can only see Likes and Comments, seeing as I don’t have access to their Insights.
I’ll compare Carousels to non-Carousels and draw a conclusion.
Here is a Carousel posted to Agorapulse:
Here is one posted to Space Walk (my small business page):
Let’s start by looking at the raw numbers of this experiment Then let’s check out the percentage difference between Instagram Carousel posts and regular posts.
Below will be the average of posts made in both categories.
That’s a 6.94% drop in Impressions and a 4.73% drop in Reach!
That’s a 5.98% drop in Impressions and a 4.43% drop in Reach!
It’s obvious that on both accounts regular photo posts with 1 image had more Reach and engagement than Carousel posts.
The 2 accounts averaged a 6.46% decrease in Impressions and a 4.58% decrease in Reach.
What about famous accounts?
Let’s take a look at a few social media experts first.
Since I obviously didn’t post these I had to go back sometimes 3-4 months to find Carousels posted by these accounts. After getting the data for the Carousel I then got the data for the regular post immediately before or after the Carousel. That way our data is as solid as can be.

@iSocialFanz (Brian Fanzo):
Here are a few national brands I drew data from:
Instagram (yes THE Instagram account on Instagram):
Hopefully you see the trend with each of these accounts.
On every single one of them the Engagement numbers (as well as Impressions and Reach) was higher on regular photo posts. The Carousels did not have any increased engagement and in many cases had a much lower engagement. Comments were higher on the carousel posts on a few of the accounts though.
So it kinda “hurt” the accounts.
Remember Instagram uses an algorithm now so the more someone engages with your posts the higher the chance they’ll see your next post.
Let’s break that down in percentages to really get a better feel of the numbers.
Other than the accounts with more comments on carousel posts every other data point tells me carousels way underperformed compared to regular posts.
The average decrease in Likes of all accounts studied was 25.64%!
Now that all the data is in we need to see if my hypothesis was correct.
You’ll recall it was: Posting an Instagram Carousel will result in an increase in engagement, primarily in Likes, as well as result in an increase in Impressions and Reach.
Based on the data I would say it was not accurate at all.
Every account studied had a major drop in Likes, Impression and Reach.
Sure, comments were up for some of the accounts. But the majority of the engagement that happens on Instagram is Liking the post, I’d say Carousels are a failure and did not produce any positive results.
Impressions and Reach being lower was a huge red flag for me as that number being lower means fewer eyeballs even had a chance at seeing my carousels.
If you’re looking for more engagement on Instagram, and we all are, I wouldn’t recommend posting Carousels to accomplish that.
It’s a cool idea to use when you want to group related photos together, or a series of pictures.
But other than that you’re better left posting those shots as individual posts and getting more engagement that way.
One of the challenges we face with our experiments is ensuring the data is still good months later.
So I re-tested Instagram Carousels on the Agorapulse and Space Walk accounts to see if the results were still relevant.
The quick answer is YES!
To re-test I posted a few carousels to each account:
Since this was simply a re-test to ensure the reliability of the initial experiment I felt this amount was sufficient.
I then gathered data from these carousels as well as posts before and after them to compare, as we did in the first study.
Here’s what I found from the re-test:
This data further cements our original findings that Instagram carousels are not good for engagement and shouldn’t be used.
The action of swiping left is un-natural for Instagram users and is likely the reason why they don’t fair well.
So there you have it! Instagram Carousels still suck!
