Algorithm (social media)
The set of rules a network uses to decide which posts each user sees, in what order, and how often.
What is "the algorithm"?
The algorithm is the recommendation engine behind every feed. Instagram's, TikTok's, X's, LinkedIn's — they all have one. It looks at signals (who you follow, what you've liked recently, how long you watched the last post, how new this one is, whether other engaged users liked it) and decides which posts to push to which feeds, in what order.
What it actually rewards
Specifics differ across networks, but the general weights are:
- Watch time / dwell time — the longer viewers stay, the more it shows the post
- Saves and shares — strong intent signals; ranked higher than likes
- Comment depth — replies on replies signal real conversation
- Recency — fresh content gets a window of pushed reach before it cools off
- Affinity — viewers who interact with your account often see more of your posts
What it punishes
- Engagement bait ("comment 'YES' if you agree")
- External link clicks (some networks demote posts that send users off-platform)
- Reposted content from other networks with watermarks
- Long gaps in posting cadence
Practical takeaway
Stop trying to game the algorithm. Make posts that earn watch time and saves from the audience you want, post on a cadence the network can predict, and the algorithm rewards you. Tools and tactics matter less than the actual content.
