Reach

What is Reach in Streaming TV?

Reach refers to the total number of unique viewers who see an ad or piece of content during a specific time period. In the context of streaming TV and CTV advertising, reach measures how many distinct individuals were exposed to a campaign—regardless of how often they saw it.

Reach is a key metric for understanding audience scale. It helps advertisers and publishers determine how many people their message is getting in front of, not just how many times it’s being shown.

How Reach Works in Streaming Environments

In streaming TV, reach is typically measured using device data, viewership logs, or panel-based insights. Each viewer is only counted once, even if they see the same ad multiple times. This sets reach apart from impressions, which count total exposures, including repeat views.

For example, if a campaign delivers 1 million impressions to 250,000 viewers, its reach is 250,000. The difference shows how frequently each person saw the ad—known as frequency.

Why Reach Matters for Advertisers

Reach is essential for measuring campaign effectiveness at the top of the funnel. A higher reach means more people were exposed to the brand or message, which can lead to stronger awareness and broader engagement.

In CTV, where audiences are fragmented across platforms and devices, reach gives marketers a clearer picture of their total impact. It also helps in planning, budgeting, and optimizing campaigns to avoid over-saturating small audiences.

When combined with metrics like frequency, conversions, or brand lift, reach becomes a powerful signal of how well an ad is performing.
