Algorithms decide who sees your posts. Learn how Instagram, Facebook, and LinkedIn algorithms work and use them to your advantage.
Organic reach on Facebook has dropped to around 5%. On Instagram, the average post reaches less than 10% of followers. You publish regularly, yet your content still gets lost in the crowd. Why do some posts get thousands of views while others don't even reach a hundred people?
The answer is always the same: algorithms.
Every social media platform uses algorithms that decide who sees your post and when. It's not a lottery but a system with specific rules. Businesses that understand these rules get reach. Businesses that don't waste time creating content that nobody sees.
In this article, we explain what social media algorithms are, how they work on individual platforms, and what universal principles are worth knowing. You'll find detailed strategies for each platform in the dedicated articles in this series.
A social media algorithm is a content prioritization system. Its job is simple: from the thousands of posts that could appear in your feed, select the ones most likely to interest you.
Why is this necessary? Because there's too much content and not enough attention. The average Instagram user could see hundreds of posts a day from followed accounts. The algorithm picks the ones with the highest chance of generating engagement.
An algorithm isn't an enemy but a tool. Businesses that understand its rules can leverage them to multiply the reach of their content many times over.
The key principle is universal: algorithms promote content that generates engagement and penalize content that doesn't. But "engagement" means something different on every platform. And that's where the differences begin.
Most businesses treat Instagram as a single channel with a single algorithm. That's a mistake. Instagram uses three separate algorithms: one for Feed and Stories, one for Explore, and one for Reels. Each has different priorities.

Facebook clearly communicates what it promotes: meaningful interactions, meaning content that generates real conversations. Substantive comments and shares with commentary carry far more weight than simple likes. Facebook actively penalizes engagement baiting ("like if you agree").
Storytelling, case studies, and controversial (but substantive) industry opinions are the formats that work best.

LinkedIn is a platform where posts can reach thousands of people even with just a few hundred followers. The algorithm prioritizes dwell time, substantive comments, and industry relevance. Formatting (short paragraphs, bullet points, a strong hook in the first lines) has a direct impact on reach.

Google Business Profile is a platform that many businesses forget about. And that's a mistake, because GBP posts appear directly in search results and on Google Maps. The algorithm rewards regularity, freshness, posts with photos, and CTA clicks. Local keywords in content strengthen your position in local SEO.

Regardless of the platform, there are principles that always work. Algorithms change the details, but the fundamentals remain the same.
Social media algorithms are not a mystery. They are systems with specific, learnable rules. Here are the three most important takeaways:
