Quick definition

A social media algorithm is the system a platform uses to decide what appears in each user's feed and in what order. It optimises for attention, showing people the content most likely to keep them engaged and on the platform. For marketers it means reach is earned by making content the algorithm wants to distribute, chiefly content that holds attention, not simply content you posted.

Where it shows up in the data

Optimises for attention

The algorithm distributes whatever keeps people engaged and on the platform, so reach follows attention, not follower count.

Early signals matter

How fast a post earns engagement and how long people watch or dwell strongly influence how widely it is distributed, which is why openings are decisive.

Saves and shares signal value

Actions that indicate real value, shares and saves, tend to carry more weight than passive likes, because they signal the content was genuinely worth it.

What it actually means

A social media algorithm ranks and selects what each user sees, replacing the old chronological feed with one optimised for engagement and time spent on the platform. It predicts, for each piece of content, how likely a given user is to watch, react, comment, share or otherwise engage, and distributes accordingly. The consequence for marketers is that reach is no longer a function of how many followers you have but of how well a post performs against what the algorithm optimises for. Signals that consistently matter across platforms include how quickly a post earns engagement after posting, how long people watch or dwell and whether it prompts shares and saves, which signal real value. This is why the opening of a video or post is so decisive, and why chasing follower count is less useful than making content that genuinely holds attention. The specifics differ and change by platform, but the direction, rewarding content that keeps people engaged, is stable.

The algorithm does not owe your followers your posts. Reach is earned by holding attention, one post at a time.

The NR take

Stop thinking about the social media algorithm as an obstacle and start thinking about what it actually rewards, which is content that holds attention. Every platform's algorithm is a machine for keeping people on the platform, so it distributes whatever does that best. That reframes the job. Reach is not owed to you by your follower count, it is earned post by post by making something people actually watch, dwell on and share. Obsess over the opening seconds, because early engagement and watch time drive how far a post travels, and value saves and shares over vanity likes, because they signal the real value the algorithm is looking for. Do not chase the specifics of each update, which shift constantly. Make content genuinely worth attention and you are aligned with what every social algorithm optimises for.

Where people get this wrong

Assuming followers guarantee reachFeeds are algorithm-ranked, not chronological, so posting no longer means your followers see it. Reach is earned by performance, not follower count.

Chasing algorithm specifics that keep changingThe exact signals shift constantly by platform and update. Reverse-engineering each change is less durable than making content that genuinely holds attention.

Optimising for vanity likes over value signalsLikes are passive. Shares and saves signal real value and tend to drive distribution further. Chasing likes alone misreads what the algorithm rewards.

Common questions

What is a social media algorithm?

It is the system a platform uses to decide what appears in each user's feed and in what order, optimised to show people the content most likely to keep them engaged and on the platform.

How do you work with the social media algorithm?

Make content that genuinely holds attention, especially in the opening seconds, since early engagement and watch time drive distribution. Value shares and saves over passive likes, and do not chase constantly changing specifics.

Does follower count still matter on social media?

Less than it used to. Feeds are algorithm-ranked, so reach depends on how well a post performs against what the algorithm optimises for, not simply how many followers you have.
