What is the difference between organic and paid reach?

Organic reach is the number of people who see your content without you paying for the distribution. Paid reach is the number who see it because you bought the impressions.

The distinction matters because the two behave completely differently.

Organic reach is earned and unstable. It depends on the platform's ranking system deciding your content is worth showing. You cannot buy it, cannot guarantee it, and cannot easily forecast it. It can also be withdrawn — organic reach for business pages on most social platforms has declined dramatically over the past decade, from figures that were once a substantial share of followers to low single-digit percentages. That decline was a business decision, not an accident: as feeds filled up and platforms monetised, unpaid distribution became the thing being sold.

Paid reach is bought and predictable. You set a budget, the platform delivers impressions, and the relationship between spend and reach is reasonably stable. It stops the moment you stop paying.

Where each genuinely works:

Organic compounds. Content that ranks in search, an email list you own, or an audience that actively seeks you out keeps delivering after the work is done. It is slow and unreliable early on.

Paid is immediate and controllable, useful for testing messages quickly, reaching people who have never heard of you, and scaling something already proven.

Two things worth understanding:

They interact. Paid distribution that generates genuine engagement often improves organic performance, and strong organic content is usually the cheapest thing to promote.

Reach is not results. Both metrics count impressions, not outcomes. A campaign with excellent reach and no conversions has failed, and reach is the easiest metric to buy cheaply by targeting people who will never act.

The most durable asset is usually the channel you own outright — an email list or a website — because no platform can adjust your access to it.
