At first glance, algorithms sound like a maths nightmare. Opaque, unpredictable, somehow eerie. But here’s the good news: you don’t need to understand them the way a data scientist analyses data. You just need to know what triggers them. And that’s exactly what we’re going to look at now. No buzzword bingo, no hype. Just the mechanics behind Instagram, TikTok, LinkedIn and the like that determine whether your content gets seen – or vanishes into thin air.
Every platform works differently
What works on Facebook flops on TikTok. It sounds obvious, but it’s constantly overlooked. Every platform has its own algorithm that responds to different signals.
- Twitter (or X, whatever you call it): location, language, user interactions. The algorithm analyses who you’re interacting with and how relevant your tweets are to that bubble.
- Facebook: engagement levels, quality, relevance. The more comments and shares, the better. But be warned: clickbait is penalised. The algorithm has become quite good at spotting cheap tricks.
- Instagram: Quality and relevance of posts, interaction history. People who regularly interact with your posts will see more of them. It’s logical, but important.
- LinkedIn: Much like Instagram – quality and relevance are key. Anyone who posts content here that suits their target audience (keyword: brand positioning!) will be rewarded.
TikTok and YouTube: Trends are a must, followers don’t matter
On TikTok, one thing matters: are you using the native features? Effects, sounds, text styling – these aren’t just gimmicks. They’re fuel for the algorithm. And here’s where it gets interesting: follower counts don’t matter when it comes to visibility. An account with 100 followers can go viral if the content is right. YouTube works in a similar way. The algorithm looks at video performance, context and users’ previous viewing behaviour. Anyone who has clicked on cooking videos in the past will be suggested more of the same. The system learns as it goes.
Engagement is the key
Here’s the part you can directly influence: engagement. Comments, shares, likes – these are the signals that every algorithm understands. But how do you get them?
- Ask questions. It sounds simple, but it works. People are more likely to comment when they’re addressed directly.
- Spark debates. Be careful not to provoke at any cost. But controversial topics generate reactions. And reactions mean engagement.
- Create shareable content. Infographics, lists, how-to guides – anything that users might save for later or share with others. Saves and shares are worth their weight in gold.
Experimentation is essential. What works today may not work the same way next month. Algorithms are constantly being adjusted. Anyone who clings rigidly to a content strategy will lose out. Algorithms are tools. Nothing more, nothing less. If you understand how they work, you can use them to your advantage. If you ignore them, you’re throwing away reach. The basics are the same everywhere: quality, relevance, engagement. The rest is fine-tuning – and the best way to learn that is by trial and error.
FAQs on social media algorithms
How do social media algorithms work?
Social media algorithms determine what content users see. They assess factors such as engagement (likes, comments, shares), relevance (does the content suit the target audience) and quality (is clickbait identified and penalised). Each platform weights these factors differently. Instagram prioritises interaction history, TikTok prioritises native features, and LinkedIn prioritises professional relevance.
Why aren’t my followers seeing my posts?
Algorithms only show content to a fraction of your followers. On Instagram, on average, only 10–20 per cent of your followers see a post organically. The rest depends on engagement: those who regularly interact with your content will see more of it. Low reach often means that your content isn’t generating enough interaction for the algorithm.
Do follower numbers affect reach?
On TikTok: no. On Instagram and Facebook: to a limited extent. TikTok’s algorithm displays content regardless of follower numbers – performance (watch time, interactions) is the deciding factor. On Instagram and Facebook, large accounts have an advantage, but here too, engagement is the primary factor. A small account with a high interaction rate outperforms a large one with a passive audience.
How often should I post on social media?
It depends on the platform. On TikTok and Instagram Reels, consistency trumps frequency. 3–5 posts a week of consistent quality work better than a daily deluge without a strategy. LinkedIn prefers 2–3 posts a week. Facebook tolerates 1–2 posts a day. More important than frequency: consistency and quality.
Can I outsmart algorithms?
In the short term, perhaps; in the long term, no. Tactics such as engagement pods (groups that like each other’s posts) or bought likes are detected and penalised by platforms. Algorithms are constantly learning. What works: authentic engagement through good content that encourages interaction. No shortcuts, but sustainable reach.
