Reach

Reach is the number of unique people or accounts exposed to a piece of content during a given period.

Related terms: social reach, unique reach, audience reach, reach vs impressions, influencer marketing reach.

Why reach matters

Reach helps brands understand how many different people a creator or campaign can expose to a message. It is most useful when combined with frequency, engagement and audience relevance.

At TANKE, a French influencer marketing agency, reach is compared with budget to estimate the cost per person reached: see our influencer marketing pricing.

How brands use it

• Estimate unique exposure across creators, platforms or campaign waves.
• Compare reach with impressions to understand repeated exposure.
• Read reach alongside engagement, traffic and conversion signals before judging performance.

FAQ

What does reach mean in social media?

Reach is the number of unique people or accounts that saw content at least once.

What is the difference between reach and impressions?

Reach counts unique exposed accounts, while impressions count total content displays, including repeat views.

Is reach the same as followers?

No. Followers are a potential audience; reach is the audience actually exposed to content.
