Social media algorithms are sets of rules and signals that decide how content is ranked on a platform. They sort posts in each user's feed by how likely that person is to be interested and engage. That is why two people who follow the same accounts do not see the same content.
How do social media algorithms work?
Platforms such as Facebook and Instagram track user behaviour, interests and actions to suggest content that fits. If you are into cricket, you will probably notice more posts about it. The algorithms keep learning from how people interact, so recommendations stay fresh and relevant.
Why do social media algorithms matter for brands?
Algorithms decide which content people see out of the huge amount available. For brands, that determines how visible your posts are, both to current followers and to potential new ones.
Algorithms show people content they are likely to be interested in, based on past interactions. Like or comment on certain accounts and you see more like them.
What do social media algorithms pay attention to?
Algorithms collect user signals and match them to content. The key signals include:
- User engagement: likes, shares and comments show content is relevant and attractive.
- Relevance: keywords and hashtags give content meaning and increase visibility.
- Timing and frequency: posting consistently, when your audience is online, improves visibility.
- Recency: newer content is considered before older content.
- User interactions: the accounts a person follows, how they engage and click-through rates on links indicate relevance and quality.
- Profile authority: follower count, consistency and engagement levels affect organic reach.
- Location: algorithms consider location and demographics and often promote content to users with similar tastes.
- Content type: the same content is treated differently depending on how users interact, and many platforms prefer video because it is more engaging.
- Virality: content that is trending and being shared signals relevance.
- Watch time: how long people spend watching videos, such as Instagram Reels or YouTube Shorts.
What are the best tips for working with social media algorithms?
1. Learn social SEO
Algorithms affect search results too, so the two go together. Social SEO improves discoverability through keywords and alt text. It amplifies your content's visibility and sends positive signals back to the algorithm.
2. Know your audience
Content relevance plays a significant role in how algorithms rank posts. What counts as relevant varies by platform. Know your target audience and create content that speaks directly to their interests.
3. Work out the best posting times
Many algorithms care about how fresh a post is and how quickly it is engaged with. Find out when your audience is most active on each platform.
4. Increase comments, saves and shares
Make content that invites people to interact. Ask a question or start a conversation. Respond to comments and DMs, ideally through a centralised social inbox your team shares. Create content valuable enough that people pass it on or save it for later.
A social media contest can spike engagement, but do not run one for every post.
5. Experiment
There is no one-size-fits-all approach. Try different approaches, see what works and adjust. Testing can be simple. Notice the trends in your own feeds for ideas.
6. Share more video
Platforms are pushing video, especially short video. Reels on Meta platforms can put your content in front of people who do not follow you. Do not drop images altogether. Carousels and music can extend reach, and a still image can be turned into a video using Reels templates.
7. Lean into relevant trends
Trending topics keep people engaged, so platforms serve more of them. Do not jump on every trend. When one aligns with your brand messaging, put your best people on it. Google Trends and social listening can show what is moving in your industry. Watch for trending sounds and effects in short-form video such as TikTok, Instagram Reels and YouTube Shorts.
What should you remember?
Algorithms are always changing. Engagement, relevance, video content and consistency give you a strategy that keeps pace with shifting platform preferences. Flexibility and quick adaptation matter most.

Questions we get asked
What is a social media algorithm?
A social media algorithm is a set of rules and signals that decides how content is ranked on a platform. It sorts posts in a user's feed by how likely that person is to be interested and engage. This is why two people following the same accounts can see different content.
What do social media algorithms look at?
Algorithms look at signals such as engagement (likes, shares, comments), relevance, timing and frequency, recency, user interactions, profile authority, location, content type, virality and watch time. Many platforms favour video because it is more engaging, so watch time matters for formats like Reels and Shorts.
How can a business improve its reach on social media?
Know your audience, post when they are most active and create content that invites comments, saves and shares. Respond to comments and DMs, share more short video and test different approaches. Use social SEO, such as keywords and alt text, to improve discoverability.
Should I jump on every social media trend?
No. Trends keep people engaged, so platforms serve more of them, but you should not follow every one. When a trend aligns with your brand messaging and has real potential, it is worth putting your best people on it. Tools like Google Trends help you spot what is relevant.
