Blended Reach: Cross-Platform Audience Size

Track unique users who saw your ads across Meta, Google, and TikTok. Understand total audience size and eliminate platform overlap in reach reporting.

The total number of unique users who saw your ads at least once across all connected advertising platforms.

Meta Ads	1.8M	75%
Google Ads	420K	18%
TikTok Ads	180K	7%

Note: Platform totals may exceed blended reach due to cross-platform audience overlap.

How It Works

Blended Reach aggregates unique user counts from all connected ad platforms. Each platform reports its own reach independently—users who see ads on multiple platforms are counted once per platform but may appear in multiple platform totals. The blended figure provides a unified view of total audience exposure.
