Algorithm
What is the Algorithm?
The Algorithm. Said in hushed tones by social media managers worldwide, blamed for everything from declining reach to bad hair days, and understood by approximately nobody — including, allegedly, some of the engineers who built it. In the context of social media, "the algorithm" refers to the set of rules, signals, and machine learning models that each platform uses to decide which content to show to which user, and in what order. It's the invisible bouncer at the club door of your audience's feed, and it decides whether your content gets VIP treatment or is left outside in the rain.
Every major platform has its own algorithm, and they all work differently — though they share a common goal: keep users on the platform as long as possible. The longer people scroll, the more ads they see, the more money the platform makes. Your content is just a means to that end. Romantic, isn't it?
The reason "the algorithm changed" has become the universal excuse for poor performance is that these systems are constantly evolving. Platforms tweak their algorithms regularly (sometimes daily), and they rarely announce exactly what changed. So when your reach drops 40% overnight, you're left playing detective with no clues, no suspects, and a client breathing down your neck.
How is it applied?
Each platform's algorithm considers hundreds of signals, but here's a simplified breakdown of the major ones:
Instagram: Prioritizes content based on relationship (how often you interact with the poster), interest (predicted based on past behavior), timeliness (newer posts rank higher), and session time. Reels get boosted to compete with TikTok. Shares and saves now carry more weight than likes.
TikTok: The For You Page algorithm is arguably the most powerful. It weighs watch time (did you watch the whole video?), replays, shares, comments, and whether you followed the creator after watching. Follower count matters less here — a brand-new account can go viral if the content hits.
Facebook: Prioritizes content from friends and family over brand pages (R.I.P. organic brand reach). Meaningful interactions — especially comments and shares — signal the algorithm to distribute content more widely. Video, especially live video, gets preferential treatment.
LinkedIn: Favors content that generates conversation (comments over likes), rewards posting consistency, and has a longer content lifespan than other platforms. Your post can keep gaining traction for 24-48 hours.
Real-world use case
You post a carousel on Instagram at 9 AM on Monday. Within the first hour, it gets 50 likes, 20 comments, and 15 saves. The algorithm interprets this early engagement as a signal that the content is valuable and starts showing it to a wider audience beyond your immediate followers. By the end of the day, the post has reached 3x your typical audience. The next week, you post a similar carousel but at midnight on a Saturday. Crickets. Same content quality, different timing, wildly different algorithmic treatment.
Pro tip
Stop trying to "hack" the algorithm and start working with it. The algorithm's job is to surface content that users find valuable. So create valuable content — genuinely helpful, entertaining, or inspiring — and optimize for the signals each platform cares about most. Study your analytics to understand what's working, stay updated on platform changes (follow credible sources, not conspiracy theorists), and above all, remember: the algorithm isn't your enemy. Bad content is.
