The best way to keep track of Instagram comments is to sort posts by comment count using a third-party tool, since Instagram’s own app has no built-in sort function. I tried scrolling through my grid manually first, which took ages and still missed older posts. A proper analytics tool pulls every post into one list, ranked highest to lowest, so you can spot your most-discussed content in seconds rather than guessing.
The short version: Instagram gives you a built-in way to sort your own posts by comment count through Insights, but there is no native tool to sort someone else’s account the same way, so you either scroll and log numbers manually or use a third-party analytics tool that pulls the data for you. Before you get excited about a post with 900 comments, check what those comments are, because a huge chunk of high-comment posts are giveaways, complaints, or comment-bait rather than genuine engagement.
Why this is harder to do than people expect
Every time I run a content audit for a client, someone on the call asks “can’t we just search Instagram for the posts with the most comments?” No. You can’t. Instagram has never built a public search that sorts posts by comment count, on your account or anyone else’s. It sorts hashtag pages by “top posts,” which is a mix of likes, comments, saves, shares, and recency, weighted in a formula Meta has never published. That’s not the same thing as raw comment count, and treating it as such will send you chasing the wrong posts.
This matters because comments are the metric that correlates with reach on Instagram, more than likes do. Meta’s own product team has said publicly that comments carry more weight in distribution than likes, because a comment signals a stronger reaction than a tap. So if you’re trying to reverse-engineer what worked, comment count is a better clue than like count. It’s just annoyingly hard to isolate.
Finding the most-commented posts on your own account
This part is easy once you know where to look, and most business owners never find the screen because it’s buried three taps deep.
- Open the Instagram app and go to your profile.
- Tap the menu icon (three lines) and select “Insights.”
- Tap “Content you shared” then choose “Posts.”
- Tap the filter icon, set your date range (I’d pull the last 90 days minimum, ideally a full year), and under “Sort by” choose “Comments” instead of the default “Likes” or “Reach.”
- Your posts will now list highest-comments-first.
I did this for a client, a skincare brand with about 34,000 followers, expecting the winner to be a product launch reel. It wasn’t. The top post by comments, 380 of them against an account average of around 20, was a carousel where the founder admitted a batch of a product had shipped with the wrong label and apologised. People didn’t comment to praise it. They commented to ask questions, vent mildly, and tag friends who’d bought the same batch. On paper that’s a huge engagement win. In reality it was a controversy spike, and if we’d tried to replicate “what worked” by making more posts like it, we’d have been chasing a mistake, not a strategy.
That’s the bit most posts on this topic skip over: a high comment count is not automatically a good sign. It just means people had something to say. Sometimes that something is “love this,” and sometimes it’s “this is the third time you’ve done this.” Sort by comments, then read them, every time.
Finding the most-commented posts on someone else’s account
This is where it gets manual, and I want to be honest about that rather than pretend there’s a magic search box.
Option one: scroll and log it yourself
Open the profile on desktop (web.instagram.com is easier for this than the app because the layout is cleaner to scan), open each post, and note the comment count. For an account posting three times a week, checking the last three months means logging around 36 posts. Tedious, yes, but it’s free, it’s accurate, and it teaches you patterns you’d miss with a tool that just spits out a spreadsheet. I do this manually for any competitor I’m studying seriously, at least once, before I ever trust a tool’s numbers for that account.
Option two: third-party analytics tools
Tools like Social Blade, Iconosquare, Sprout Social, Metricool, and Hootsuite’s analytics dashboard can pull top posts sorted by comments, but with a catch: most of them only give you that granular sort for accounts you own and have connected via the official Instagram API. For public accounts you don’t own, you generally only get follower growth trends and estimated engagement rate, not a clean comment-sorted list. Social Blade is the exception for rough public estimates, but the numbers lag and aren’t exact.
Option three: hashtag and topic research
If you’re not researching one specific account but trying to find the highest-comment posts in a niche, hashtag search is your entry point, even though it sorts by “top” rather than pure comments. It’s worth knowing that hashtags are still worth using in 2026, just not the way they were used in 2015, and where you place them changes how discoverable a post is, which is part of why some posts rack up comments and others in the same niche don’t; I’ve written about whether hashtags belong in the caption or the comments if you want the specifics.
A word of caution here that gets glossed over constantly: any tool or browser extension promising to “unlock” full comment analytics on accounts you don’t own is either scraping Instagram in a way that breaches its terms of service, or it’s a modded app pretending to be an official feature. I’ve looked into this exact category when researching what people were being sold as “Instagram Plus” upgrades, and it’s the same pattern as with modded Instagram apps promising features that don’t officially exist: you hand over your login credentials, the app scrapes on your behalf, and you’re the one who gets rate-limited or flagged, not the developer. If a tool needs your Instagram password to show you someone else’s comment counts, that’s your answer.
What high comment counts tell you
Once you’ve got your sorted list, whether it’s your own account or a competitor’s, the real work starts, because comment count on its own is a headline number with no context. Break down what’s inside the comments before you draw conclusions:
- Giveaway comment-bait. “Tag 3 friends and follow to win” posts routinely hit 3 to 10 times a normal post’s comment count. That’s not organic interest in your content, it’s a mechanic. Strip these out before you benchmark anything.
- Complaints and customer service threads. If half the comments are questions like “did you cancel my order” or “why hasn’t this arrived,” you’ve found a support problem, not a content win.
- Genuine conversation. People disagreeing, sharing their own version, asking follow-up questions unprompted, these are the comments that indicate a post resonated. This is the smallest category on most accounts and the one worth studying.
- Pods and reciprocal commenting. Some creators are in engagement pods where members comment on each other’s posts within minutes of publishing regardless of content quality. You’ll spot these because the comments are generic (“great post!”, “love this 🔥”) and arrive in a tight time cluster.
I’ll say the uncomfortable part plainly: most “top 10 posts by engagement” case studies you’ll read never separate these categories. They screenshot a comment count, call it proof of a winning strategy, and move on. If you’re auditing your own content or a competitor’s, spending twenty minutes reading the top 10 comment threads will tell you more than any dashboard number.
A quick real example of getting this wrong, then right
Years ago, back when I was still leaning heavily on Instagram as my main channel, I tried to copy a format from a bigger creator whose post had over 1,000 comments, an unusually high number for their account average of around 60. I assumed it was the topic (a hot take on productivity) that made it fly. I made three posts in that style over the next month. Nothing came close. It was only when I read the original 1,000 comments, months later, that I noticed the account had run a giveaway in the caption, buried after the third line, offering a free course seat to a random commenter. The topic had nothing to do with it. The prize did. Lesson learned the slow way: sort by comments first, read before you copy, always.
Building this into a regular habit, not a one-off audit
If you only check your most-commented posts once a year during a big strategy review, you’ll miss the pattern entirely. I check mine monthly now, using the same Insights filter, and I keep a simple running note of which posts made the top five and why, in a plain document rather than a fancy tool. Over a year that note becomes a useful record of what your specific audience responds to, separate from what’s trending generally.
It also helps to remember that comments aren’t the only signal worth tracking alongside this. Saves and shares tend to indicate quieter, more durable value (people saving a post to come back to it, or reposting it to their Instagram Story via a reshare), while comments tend to spike on anything that invites a reply, a debate, or a reaction. A post with 15 comments and 400 saves might be doing more for your business than one with 300 comments and 5 saves. Look at both.
And if you’re building out a whole account from scratch, worth knowing that even something as small as how you choose your Instagram handle shapes how easily people find and remember you when they do want to come back and comment again, which is part of why comment volume compounds for established accounts with clear, memorable names and stalls for accounts that keep rebranding.

Frequently asked questions
Can I sort another person’s Instagram posts by comment count without a tool?
Not automatically. You have to open each post individually and note the comment count yourself, since Instagram has no native feature to sort a public profile’s grid by comments, only your own connected account gets that filter inside Insights.
Is comment count a good measure of Instagram content success?
Only if you check what’s inside the comments first. Giveaways, complaints, and comment-bait captions inflate the number without meaning the content was good, while a smaller number of genuine, conversational comments often signals stronger content than a huge pile of “tag a friend” replies.
Do third-party analytics tools show comment counts for competitor accounts?
Most tools like Sprout Social, Iconosquare, and Metricool only give you that detailed sort for accounts you own and have connected through Instagram’s official API, so for competitor research you’re usually limited to rough public estimates or manual checking.
Why do comments matter more than likes for Instagram reach?
Meta has said publicly that comments are weighted more heavily than likes in its distribution decisions, since a comment requires more effort than a tap and signals a stronger reaction, which is why chasing comments (the genuine kind, not comment-bait) is a more useful goal than chasing likes.
