Reach
Reach refers to the number of unique users who see a piece of content. It shows how many different people a post actually reaches, not how many times it is viewed.
How it works
When content appears in feeds, stories, or search results, platforms count how many individual users are shown that content. Each person is counted only once, even if they see the post multiple times.
Reach focuses on audience size, not repetition.
What affects reach
Reach can be influenced by:
- engagement levels
- algorithm decisions
- posting time and frequency
- follower activity
Content that performs well is often shown to more users.
Reach vs impressions
Reach and impressions are often confused:
Reach counts people
Impressions count views
A single user can generate multiple impressions but only one reach.
Why reach matters
Reach helps measure:
- how far content spreads
- audience growth potential
- visibility of a post or account
It is a key metric for creators and marketers.
Simple example
Reach is like counting how many people saw a billboard, not how many times they looked at it.
