Why Your Instagram Content Isn’t Getting Seen, and What to Do About It
Here's what most people get wrong about Instagram: they treat it like a single algorithm that either works or doesn't. But that's not how it actually works. And if you're managing social for a medical practice, orthopedic device company, or trying to establish yourself as a key opinion leader, understanding the difference is the difference between building an audience and shouting into the void.
Recently, Adam Mosseri, Head of Instagram, broke down exactly how the platform's ranking system works in an Instagram Reel. It's the kind of insight that fundamentally changes how we think about social strategy for our healthcare clients. Here's what matters.
You're posting on Instagram. You hit publish. And then—crickets. Or worse, your post disappears into the feed before your followers even see it.
There Isn't One Algorithm. There Are Many.
Let's start with the obvious thing that nobody talks about: Instagram doesn't have one algorithm. It has several.
As Mosseri puts it directly: "One thing people often say is the algorithm, but the truth is there isn't one algorithm on Instagram. There are many. We have different ways to rank different types of content."
Specifically: "Stories are different than reels, are different than explore, are different than feed."
And within each of those, there are actually two separate ranking systems running: one for content from accounts you follow, and another for recommendations from accounts you don't follow yet. As Instagram describes it, "There are two general types of algorithms, one to rank content from accounts you follow and one to rank content from accounts that you do not follow. We call those recommendations."
This is important because it means your strategy has to be different depending on where you want your content to show up.
If you're trying to build authority as a thought leader in orthopedic marketing or medical device strategy, you're probably not just hoping your existing followers see your posts. You're trying to reach new people who don't follow you yet. That means you need to understand how the recommendation algorithm works—not just the follower feed.
How Instagram Actually Decides What You See
Here's the core logic: Instagram tries to predict what you're interested in based on what you've done before.
As Mosseri explains it: "What we're trying to do is make an educated guess about what you're interested in by looking at what you've historically done on the platform and then predicting how likely you are to like, comment, send to a friend, watch a video, watch it to the end."
The platform looks at your history. What posts did you linger on? Which ones did you like, comment on, send to friends, or watch all the way through? All of those actions are signals—signals that you were interested in that content.
Instagram then uses those signals to calculate a relevancy score for every post you could see. As the team describes it: "We use those predictions to come up with relevancy scores for every post you could see. And then we order posts by those scores."
Recency matters. A lot. Mosseri notes: "Recency matters a lot, which is why they're roughly in chronological order, but not strictly in chronological order." Most of what you see is still roughly in chronological order—content you're seeing was published recently. But it's not strictly chronological. The algorithm makes room for older posts that it thinks you'll actually care about, and pushes down new posts that look like you'll probably scroll past.
Think of it this way: Instagram isn't trying to show you everything. It's trying to show you the things you're most likely to engage with. And it knows what you engage with better than you do.
Why does this matter to Instagram? Because the alternative hurts everyone. As Mosseri notes: "We also know that when we don't rank content, people see a lot less content on Instagram and the average reach for the average creator goes down significantly because the overall pie gets smaller."
What This Means for Healthcare Marketing
If you're running social for a medical practice or positioning yourself as a thought leader, here's what changes:
Posting frequency doesn't win. This is the part that makes some practices uncomfortable. Without algorithmic ranking, Instagram would look very different. Here's how Mosseri frames it: "If we do not rank content, we know that the feed for the consumer gets overrun with content from the accounts that post the most often... And so Instagram moves to a much less friend oriented place and a much less creator oriented place and towards a much more business news publisher oriented place."
In other words: large health systems and device companies would dominate. Independent practitioners would disappear. The algorithm actually levels the playing field for quality content from smaller organizations.
A single, high-engagement post from a thoughtful practitioner can reach more people than five mediocre posts from a larger organization. The algorithm works for you if your content is worth engaging with.
That doesn't mean post once a month. But it means you should care more about whether your posts are worth engaging with than whether you're posting every single day.
Engagement signals matter because they're actual interest signals. Every time someone watches your Reel all the way through, or saves your carousel about CPT coding strategy, or sends your post to a colleague—that's a signal to Instagram's algorithm that your content is worth showing to more people.
This is why "hear from the horse's mouth" content works so well. Avideo of a surgeon explaining a new technique, or a practice owner breaking down referral challenges, or a CMO sharing what actually works in medical device marketing—these things get watched. They get saved. People send them to colleagues. The algorithm sees that and amplifies it.
Your existing followers aren't your only audience anymore. The Explore page and recommendations in the feed come from accounts you don't follow yet. This is where growth happens. But the algorithm that powers recommendations is different from the one that ranks your follower feed.
For Explore and recommendations, Instagram is making educated guesses about what you might be interested in based on what you've already interacted with. If you've been liking posts about orthopedic marketing, it'll start recommending posts about practice growth, medical device strategy, and healthcare communication.
This is why your content strategy should include topics and formats that appeal beyond just your current followers. You're not just serving the people who already know about you—you're trying to be discovered by people who don't yet.
What Controls You Actually Have
This is where people usually freak out: "So the algorithm controls everything?"
Not exactly. Instagram built in tools so you're not completely at the mercy of the ranking system.
You can add accounts to Favorites, and their posts will show up higher in your feed. You can switch to a Following feed that's strictly chronological—no algorithmic ranking at all. You can tell Instagram what topics interest you, and it'll prioritize those.
But here's the thing: most people don't use those tools. They just scroll. Which means if you want your content to actually be seen by the people you're trying to reach, you have to work with the algorithm, not against it.
That means:
Create content worth engaging with, not just content to fill the feed
Post content that encourages saves and shares, not just likes
Think about whether your post would be worth sending to a colleague (because if you wouldn't, neither will your audience)
Test different content formats—Stories, Reels, carousels—because they rank differently
Understand that recency helps, but relevance wins
The Bigger Picture
Instagram's ranking system exists because without it, the platform would be broken. Practices that post eight times a day would completely drown out thoughtful clinicians and innovators. Large health systems would have all the reach. Smaller independent practices would have none.
Instead, the algorithm creates space for good ideas and authentic voices. A well-crafted post about patient experience from a mid-sized orthopedic practice can reach thousands of people. A genuine breakdown of what works in medical device marketing can become a reference point for the entire industry.
But that only works if you're posting things worth ranking.
This is why we've shifted how we think about social strategy for healthcare clients. It's not about posting more. It's about posting smarter. It's about understanding that Instagram wants to show your content to people—the algorithm's job is to figure out who those people are and why they'd care.
When you build content around that, everything changes.
Your Move
That shift alone will change your strategy.
Ready to build a social presence that actually gets seen? We help healthcare brands and practices develop strategies that work with how platforms like Instagram actually rank content. Whether it's thought leadership positioning, patient engagement, or medical device marketing, we know how to cut through the noise.
Let's talk about what your audience actually needs to see.
If you're managing social for a medical practice, device company, or building thought leadership as a healthcare professional, the question isn't "How do I get Instagram to show my posts?" It's "Am I creating posts worth showing to more people?"
