Blended Cost Per Unique Click: Cost Per Unique Ad Clicker

Blended Cost Per Unique Click measures how much you pay for each distinct person who clicks your ads. Meta is the only platform that reports unique clicks, so only Meta spend counts.

Example

Your brand ran ads on all three platforms in March:

Platform	Spend	Unique Clicks	Counted in this metric
Meta Ads	$6,300	7,000	Yes
Google Ads	$2,100	Not reported	No
TikTok Ads	$1,050	Not reported	No
Blended Cost Per Unique Click	$6,300	7,000	$0.90

Blended Spend for the month is $9,450. Dividing all of it by Meta’s 7,000 unique clicks would give $1.35, charging Meta’s clickers for Google and TikTok budgets. Counting only Meta spend keeps the figure at $0.90.

How It Works

Upstack divides spend from Meta by the unique clicks Meta reports. Google Ads and TikTok don’t report unique clicks, so their spend is left out of the numerator. In the app the formula reads Meta Spend ÷ Unique Clicks.

Unlike CPC, this metric counts each person once, so it shows the cost to reach a new engaged user rather than the cost of every repeat click.

Measuring acquisition efficiency	Compare cost per unique clicker with Meta CPC
Spotting repeat clicking	A low CPC with a much higher cost per unique click means the same people click many times
