How Social Media Decides What You See: An Expert Look At Algorithms
Have you ever wondered why certain posts always appear at the top of your Instagram or Facebook feed while others seem to vanish into oblivion? The truth lies in powerful, ever-evolving algorithms quietly shaping your daily scroll. Far from being random, these systems are designed—according to tech experts—to keep you engaged, entertained and, above all, online. But how exactly do these algorithms work, and what are they really prioritising behind the scenes?
What is a social media algorithm , really?
At its core, a social media algorithm is a set of mathematical instructions that platforms use to determine what content you see and when. Experts explain that every time you refresh your feed, the algorithm analyses patterns from your previous activity—likes, shares, comments, and viewing habits—to decide what to show you next.
These models use machine learning to identify patterns and make predictions about your interests, with the goal of maximising time spent on the platform.
The silent signals that shape your feed
While many users assume likes and comments are the primary drivers of visibility, social media analysts suggest that algorithms rely on a range of subtle indicators. These include how long you spend viewing a post, the types of content you pause on, and whether you share or save it.
According to experts, platforms also look at your direct interactions—such as sending messages, visiting profiles, or watching someone’s stories repeatedly—as signs of interest. This helps the algorithm build a personalised map of your preferences.
Why every platform’s algorithm feels different
Each social media platform fine-tunes its algorithm based on its unique purpose and user behaviour. For instance, industry insiders note that
- Instagram places heavy emphasis on personal connections and content relevance.
- Facebook prioritises deeper engagement such as group discussions and link shares.
- TikTok focuses on content discovery, using watch-time and user feedback to deliver viral material.
- YouTube evaluates watch history, video completion, and user retention to recommend personalised content.
Why your feed may feel like an echo chamber
Analysts have pointed out that algorithms can inadvertently trap users in "filter bubbles"—a digital loop where they’re shown only similar types of content. Over time, this limits exposure to diverse ideas or creators, reinforcing existing tastes and opinions.
Experts warn that while this makes the platform feel more personally relevant, it can also lead to content fatigue and reduced discovery.
Can you really 'beat' the algorithm?
According to social media strategists, there’s no foolproof way to outsmart these algorithms, but users can influence what they see by being more intentional. Engaging with varied content, muting irrelevant posts, or exploring new topics can subtly shift your feed over time.
For content creators, experts recommend focusing on genuine value and consistent engagement. Algorithms tend to reward content that prompts saves, shares, and longer viewing durations.
The future of algorithms: More personalised, more predictive
As artificial intelligence becomes more sophisticated, industry observers believe algorithms will continue to evolve. Real-time adaptation, hyper-personalised suggestions, and AI-curated experiences are already being tested, pointing to a future where your social media feed could feel almost tailor-made.
Understanding how algorithms function not only demystifies what you see but also helps you regain control of your digital experience. With expert insights revealing the complex mechanics behind the scenes, it’s clear that the more you understand the system, the better you can navigate it.

How Social Media Algorithms Shape What You See: Key Questions Answered by Experts
Have you ever scrolled through your feed and wondered why certain posts always appear while others never do? Whether it's Instagram Reels, YouTube Shorts, or trending TikToks, the content you're shown is far from random. Social media platforms rely on complex algorithms to tailor what you see, often based on behaviours you don't even realise they're tracking. Below, we break down some of the most pressing questions about these algorithms and explain—according to industry experts—how they’re shaping your digital experience.
How do social media algorithms decide what you see?
At the heart of every social media platform is an algorithm designed to personalise your experience. According to tech experts and former platform engineers, these algorithms work by collecting data on your interactions—likes, comments, shares, time spent on posts, and even what you pause to watch. This data is processed to build a profile of your interests and preferences.
Once the system understands what you engage with most, it starts curating your feed to prioritise similar content. For example, if you frequently like fitness videos or cooking reels, you'll likely see more of the same from both creators you follow and new ones suggested by the platform.
How do algorithms decide what content to show users?
Algorithms don’t make decisions based on content alone—they prioritise based on predicted engagement. The aim is to keep users on the app longer. That means you’re more likely to be shown content that matches your previous behaviour or has performed well with others in your demographic or location.
Experts note that machine learning models are used to continuously update your feed preferences. These models score every possible piece of content on your platform based on how likely you are to interact with it. Higher scores mean higher visibility in your feed. The criteria may vary slightly from platform to platform, but most consider relevance, timeliness, and popularity as major factors.
In what ways are social media algorithms influencing your point of view?
While algorithms aim to be helpful by showing users what they’re most interested in, this same logic can limit exposure to diverse perspectives. Experts call this phenomenon an 'echo chamber', where users repeatedly see content that reinforces their existing views or interests.
Over time, this can subtly influence how users perceive the world. If your feed is constantly filled with a specific political opinion, lifestyle trend, or cultural stance, it can start to feel like that’s the majority view—even if it’s not. Researchers in digital media warn that this feedback loop can shape public opinion, consumer choices, and even voting behaviour.
How do algorithms and filter bubbles decide what we see on social media?
A filter bubble is created when an algorithm isolates you from information that contradicts your current beliefs or habits. This happens because the system is optimised to increase user satisfaction and engagement. If you regularly engage with a specific kind of content—say, luxury travel or tech reviews—the platform learns to filter out posts that don't match that niche.
Experts caution that while filter bubbles enhance personalisation, they can also distort reality. By constantly feeding users content that aligns with their views, social media risks deepening divides and making users less open to alternative viewpoints.
