We've all been there before. 30 videos deep into reels, brain fried, trying to come up with a comment that other viewers will like. Commenting on Instagram posts is no easy task, so we've put together an evidence-based guide that teaches you reusable strategies for developing Instagram comment ideas. Our analysis draws on 101 comments from an anonymized dataset of Instagram comments that received nearly 800,000 likes in total.
We’ll begin with strategies that stay close to what the post already contains. From there, we’ll look at how you can add a familiar outside lens, then we'll explore how to invent a line, reaction, explanation, or continuation that builds on the post. But before all that, we'll first talk about why we took the time to derive strategies from these viral comments, rather than just giving them to you to copy and paste.
Why generic comment lists are hard to use
Generic comment lists can still help you find phrases for a broad situation. For example, comment lists with categories such as selfies, outfits, birthdays, and friends tell you where those comments should be used. However, even though the comment may fit the general topic, it often has little connection to the post you're commenting on.
A good comment is usually built from something specific within the post. For example, you might focus on any one of these details:
- a line someone said
- an expression someone made
- an action someone took
- a contradiction
- a character
- a feeling someone expressed (or you felt)
- an implied consequence
These details are the building blocks to start with when creating your comment.
Strategy #1: Work with what is already there
We placed this strategy at #1 for a reason. It's the first thing you should do when considering what comment to write. Look closely at what the post has already given you. It will very often contain enough material on its own for a strong comment. The following examples are just a few ways you could do this.
Say what everyone noticed
There is an important difference between narrating a post and selecting the moment that carries its meaning. When commenting, you want to focus on selecting a specific moment, as well as selecting the right moment.
For example, the comment “‘you're having a big feeling and that's ok’ preach mama” responds to a mother who automatically uses parenting language while socializing with an adult friend. The quoted line contains this role crossover. It sounds appropriate when spoken to a child, but its appearance in an adult conversation makes the mother's parenting habits immediately recognizable. The additional phrase offers a short reaction without explaining the whole scene.
In another video, a toddler continually praises her father during a meal, prompting the comment “‘Good job daddy’ she's got her priorities straight 😭.” The quotation identifies what she keeps saying, while the second half explains what that repetition reveals about her attention. The comment selects the pattern viewers are reacting to.
Quotation marks should only be used when the words appear in the post. Even then, quoting any memorable phrase is not enough. The selected words should reveal the post's central dynamic, or the comment should add a concise interpretation that explains why the line matters.
Selection does not have to involve dialogue. In a post where a cat calmly stares into the camera after supposedly bullying other cats, the comment “No remorse in those eyes” chooses the expression as the defining moment in the video.
Here's another non-dialogue example. In this video, a woman reacts to increasingly bad mispronunciations. The comment “The EXACT moment her brain broke 💀” directs viewers toward the instant when her composure changes. Rather than summarizing every mispronunciation, the comment identifies the major turning point in the video.
When using this approach, identify the single detail that best explains the post's effect. That detail might be quoted exactly, pointed out in an expression, located at a precise moment, the list goes on. The important part is that other viewers are easily able to identify why the detail you're pointing out is important, even if it means adding a brief explanation.
Highlight the contrast
One detail will not always contain the post's meaning. Sometimes the post's meaning only becomes clear when two contrasting details are placed together. When the post already contains that mismatch, it's often enough just to point it out for others to see and resonate with.
The following video is a clean example of this. In this video, two people react differently to the same information (running pace). The first person, a runner, describes a pace as ordinary while a non-runner treats it as extraordinary. The comment “‘pretty decent’ vs ‘ARE YOU GOING TO THE OLYMPICS’” extracts both lines and places them next to each other. The difference between their reactions is already comedic, so no additional explanation is needed.
In another video, a comment states “When your mom thinks she's Madonna but you think she's having a midlife crisis” in response to a mother and daughter viewing the mother's costume and behavior from very different perspectives. Their contrasting opinions, exaggerated in this comment, are similarly funny.
Remember that both sides of the contrast must be supported by the post, whether they are directly quoted, paraphrased, or revealed at different points. If you need to invent an unsupported perspective or come up with a second joke to support your comment, this is probably not the right strategy to use.
Use absurd exaggeration
Start by identifying what is literally happening. Then decide which quality or consequence could be intensified.
For example, in one video an airplane passenger becomes more forgiving of a family's crying baby after receiving chocolate. The comment “Chocolate really solves everything 😂” expands that small success into a universal solution. The word “everything” is clearly an exaggeration, but the post did show chocolate successfully changing one person's reaction.
In another video, an employee rushing through lunch prompted the comment “Bro's literally speedrunning his lunch break 😭.” “Speedrunning” brings ideas of urgency and optimization into the scene, and the comment remains grounded because the employee is already eating unusually quickly.
Comparisons can make an observable quality feel even more extreme. The comment “She's casually running faster than my car 💀” is in response to a runner maintaining an exceptional pace. The car turns a general reaction such as “she is very fast” into a vivid and absurd comparison. The word “casually” heightens the effect further by contrasting extraordinary performance with apparent ease.
You can also exaggerate a consequence that the post clearly implies. For example, in one video a character committing a long sequence of workplace violations prompted the comment “HR's entire budget is just HER 💀.” The literal premise is that one employee creates an unusually large administrative burden. The comment extends that burden until she supposedly consumes the department's entire budget. Although the financial claim is absurd, the workplace behavior has already established the connection to HR.
Sometimes one detail is enough to carry your comment. In other posts, the building blocks come from the relationship between details. If you find yourself stuck, reaching for exaggerations and absurdity is often a helpful way to go.
Strategy #2: Reference external ideas
Another great strategy is bringing in ideas from outside of the post. These ideas might come from a game, a familiar social belief, or just regular life. Anything goes, as long as everyone else knows what you're referencing. For example, a gaming reference under a beauty post probably won't land well, so choose wisely.
Apply a familiar cultural analogy
A cultural analogy takes the rules of a familiar system and splices them into a scenario in which they would not ordinarily apply.
For example, in one video a father performs a corny fishing prank, prompting the comment “dad joke level: expert”. The ranked-skill analogy turns an intentionally groan-inducing joke into evidence of mastery.
In another post, a man returns (presumably after a period of not posting) with dramatically improved handstand strength. A viewer comments “He literally downloaded a strength patch”. Rather than treating the improvement as gradual physical development, the comment makes it look like an upgrade that was installed between appearances.
Gaming language can perform a similar job when someone’s behavior changes during a clip. “This manager unlocked FRIENDSHIP MODE at corporate 😭” describes a manager switching from supervising others to treating one employee like a friend. The change in their workplace relationship becomes an activated setting.
The same kind of language serves a different purpose in the comment “Bro unlocked extrovert mode”. Here, an introvert temporarily becomes outgoing, so the game setting represents an unlocked personal state that can be switched on and off.
Cultural familiarity makes these analogies recognizable, but recognition is not enough. The analogy must explain something specific about the post. If you could attach the same reference to any clip without changing its meaning, the analogy probably has not earned its place.
Connect it to a familiar stereotype
You can also source references from familiar expectations about how people, families, professions, or institutions behave. Instead of borrowing a system with rules, this approach turns one scene into an exaggerated example of a recognizable social belief.
You need to use stereotypes carefully. If you're questioning whether or not to post something, probably don't.
Here's an example of how you can use them safely. In one video a child innocently exposes an affair, and someone responds with “kids are the ultimate snitches 💀”. The comment draws on the familiar stereotype that children reveal information adults intended to keep private. Calling the child a “snitch” exaggerates innocent disclosure through language associated with deliberate betrayal.
In another video, a basic job involving closing a door receives the comment “Mans really out here with ‘door closer’ as his LinkedIn title 💀”. The underlying joke is a recognizable belief about professional branding. An ordinary task is treated as though it has been polished into an impressive occupational title.
Make an absurd comparison
Using an outside lens does not always mean referencing an established cultural idea or a broad social belief. Sometimes making a comparison to a radically different thing, regardless of what it is, is just as effective.
For example, consider the comment “Watering the kids like houseplants💀”. The video this comment is posted under shows children being splashed with water. Comparing children with potted plants creates an absurd image that other viewers resonated with and found funny.
In another video, a dog escapes an ear cleaning while carrying a plush lamb, and a user commented “she grabbed her lawyer and fled 💀”. The dog becomes a person escaping a crisis, while the plush lamb becomes the attorney taken along. This comment not only draws an absurd connection between these ideas, but also imposes the emotions that a person would feel when fleeing with their lawyer, such as panic and guilt, onto the dog and her plushie, which is accurate to the situation. This unexpected connection likely contributed to the success of this comment. The more unexpected but accurate connections, the better.
Strategy #3: Invent your own ideas
The core of this strategy is basing your comment on an idea that is not present in the post, nor a reference to an external idea. In fact, the following approaches move progressively farther from what actually appears in the post.
Imagine what they would say
Invent a line that translates what the subject already appears to communicate without words.
For example, the comment “Bro said ‘watch this glow up’” responds to a dramatic edit that reveals a character’s more mature appearance. The character does not explicitly say these words, but by acting like the character said them, the comment treats their change in appearance as something the character deliberately controlled.
The comment “Baby said ‘we doing this MY way’ 😭” uses the same basic approach. A baby grabs at different outfit options while someone else is trying to choose an outfit for them. The invented declaration of control turns that interference into an apparent intention. Instead of describing each movement, the comment expresses what the grabbing seems to communicate.
In the comment “Kai said ‘I'm a lover not a fighter’”, a dog looks guilty after a boarding report about humping other dogs. The report supplies the accusation, while the dog’s expression makes a comic self-defense feel connected to the post.
The next approach takes this strategy one step farther by adding a new actor who is not visible in the post.
Imagine how someone off-screen would react
An off-screen reaction works when an absent person or institution has a clear reason to care about what the post shows.
For example, the comment “FBI intern frantically taking notes rn” appears under a satirical tutorial that explains identity forgery and FBI evasion in unusual detail. The FBI has an obvious institutional connection to the subject, but the comment reverses the expected knowledge relationship. Instead of monitoring or already understanding the techniques, an intern is imagined learning from the tutorial.
By contrast, “Gordon Ramsay's lawyer is typing” imagines punishment rather than learning. The post turns Beef Wellington into pizza, which supplies the recognizable connection to Gordon Ramsay. Bringing in his lawyer exaggerates the culinary alteration into an offense that supposedly demands an immediate legal response.
In both cases, the absent party has a direct stake in the post’s subject, and the imagined action frames that relationship in a humorous way.
Invent a ridiculous explanation
You can also treat an unusual scene as an effect and invent an impossible cause for it, or conversely treat the scene as an impossible explanation for some ridiculous downstream effect.
Consider, for example, the comment “bro forgot he had bones 😭”. The post this comment was posted under shows a cat sleeping in contorted positions that appear to ignore normal skeletal limits. Forgetting about its bones becomes an immediate fictional cause for the pose.
The comment “ah so THIS is how the people who crank our AC down to the lowest possible setting grow up” responds to babies napping outdoors in winter. The post shows an unusual comfort with cold conditions, and the comment projects that trait forward into adulthood. The scene supposedly explains where adults who prefer extreme air conditioning come from.
The first comment invents a cause for what is happening in the present scene. The second comment flips this around by using the scene as an absurd explanation for a commonly known behavior.
Imagine the next episode
When a post has a repeatable premise, you can suggest a new subject that would support the same format. A useful suggestion identifies what makes the original idea work and preserves that structure instead of merely asking the creator for more content.
For example, the comment “do hotel front desk next 👀” responds to a skit that dramatizes flight attendants’ unspoken thoughts. Hotel front-desk staff work in another customer-facing service role where unspoken reactions can support the same premise. The comment therefore changes the subject while keeping the format intact.
Once you can recognize what kind of invention a post supports, the next step is choosing one approach and turning your observation into an original comment.
Our commenting strategy table
We've just gone through a lot of information. To make it easy for you to figure out what strategy to use when you comment, we've condensed everything we've talked about into a table you can easily reference whenever you need it.
| What you notice in the post | What to try |
|---|---|
| A line, expression, action, or feeling already stands out | Say what everyone noticed: Spotlight that exact moment and give viewers a concise way to recognize it together. |
| Two statements, reactions, moods, or outcomes clash | Highlight the contrast: Put the opposing sides together so the mismatch becomes unmistakable. |
| The post already contains an exaggerated premise or reaction | Use absurd exaggeration: Push the same idea beyond realistic bounds without changing its direction. |
| The moment fits an established framework from gaming, software, advertising, rankings, or another shared reference | Apply a familiar cultural analogy: Describe the post through that recognizable framework. |
| The post evokes a familiar belief about a role, profession, group, or type of person | Connect it to a familiar stereotype: Use the specific scene as an exaggerated instance of that belief. |
| Two visibly similar actions or objects belong to obviously incompatible categories | Make an absurd comparison: Map one onto the other to create a ridiculous mental image. |
| A visible person or animal behaves as though they might say an unstated line | Imagine what they would say: Write the line implied by the behavior without presenting spoken dialogue as invented. |
| Someone absent from the post would have a recognizable reaction to it | Imagine how someone off-screen would react: Add that person’s plausible but fictional response. |
| Strange behavior invites an impossible cause | Invent a ridiculous explanation: Explain what viewers see through a foolish premise that still connects to the evidence on screen. |
| The format naturally invites another installment | Imagine the next episode: Propose where the creator could take the same premise next. |
How to start writing your own viral comments
These comments are great examples of several creative strategies, but it's up to you to come up with your own original comments. As we mentioned, originality comes from noticing something particular in the current post and building your unique response around it. You can use the following process as a general guide.
-
Identify the exact source detail. Look for the line, expression, action, contradiction, feeling, or implied consequence that deserves a response. Deciding only that a post is funny or that someone looks good is too broad. Find the particular feature creating that impression. Very often you'll feel when a specific scene catches your eye or makes you react before you can logically identify why.
-
Choose the clearest strategy. Pick a strategy that we discussed, or come up with one of your own. If you find yourself torn between multiple options, remember that there's no such thing as an incorrect strategy. Try to detach from the outcome of the comment and treat it as an isolated experiment. If it goes well, then you can reuse a similar strategy next time. If it doesn't, then you know to try something else.
-
Write the comment and keep it short. Let the context of the post do the work. Try to write your comment so that you convey as many ideas and emotions as possible in the fewest words. Consider using emojis, abbreviations, and other creative alternatives :)
-
Learn as you go. Keep an eye on your comments after you post them. Observe whether or not they gain traction along with the post, or if they fade away as the post begins to grow. Notice which strategies, formats, phrasings and other factors are most effective, and the specific types of videos they're effective for. Most importantly, read other people's comments. Take their ideas and use them for yourself.
This whole process can be exhausting to do alone. Sociable AI helps marketers avoid the taxing process of doomscrolling and coming up with comments from scratch. Sociable AI's Discovery feature helps find relevant and trending posts, analyzes the context, and suggests comments based on what each post contains. Your job is just to approve the comment and then publish it.
Putting it all together
Commenting on other people's posts is a great way to increase your account's visibility on Instagram. Needless to say, it is also difficult to repeatedly come up with comments that consistently earn likes. With this analysis of over 100 viral comments, you'll have one more tool in your arsenal to tackle the task of building your account's visibility through commenting.
FAQ
What are the best comments for Instagram?
The best comments fit their particular context rather than using a universally effective phrase. Your comment should respond to a specific detail, create a relationship viewers can understand, and use a tone that fits your relationship with the poster. Keep it no longer than necessary, then check whether it could make equal sense beneath an unrelated post. If it could, make it more specific.
What is a good comment on a picture?
Start by looking for an expression, action, visual contrast, mood, or implied outcome within the picture. If the caption provides a more interesting detail, you can respond to that instead. Choose the feature that gives you the strongest reason to select, contrast, intensify, compare, or invent rather than reacting only to the general appearance of the image.
How do you hype someone up in the comments?
Identify the particular look, strength, action, or achievement that deserves praise. You can then intensify that quality as far as the post and your relationship with the person reasonably support. Capitalization, punctuation, and emoji may reinforce the enthusiasm, but those markers should support a specific reason for the praise rather than replace it.
What should you comment on a friend's post?
Friendship gives you more shared context and may support warmer praise or more playful teasing. However, your comment should still connect to something visible or stated in the post. Use shared history only when the relationship will remain understandable and appropriate. Avoid turning private context into an unsupported joke at your friend’s expense.
What are some good short comments for a friend's picture?
A good short comment does not have to be generic or limited to one word. Choose one detail and let the picture provide the obvious setup. Keep the word, contrast, or implication that makes your response belong beneath that image, then stop once the connection is clear instead of adding several versions of the same praise.
How do you write a funny Instagram comment?
Look for contrast, a reversed expectation, a detail you can intensify, a recognizable comparison, or an implied consequence you can extend. The humor should remain understandable from the post rather than depending on a random punchline. If you use teasing, keep the focus on the supported situation instead of making an unrelated personal attack. Punctuation or emoji can clarify irony when necessary.
