Blended Cost Per Like: Engagement Efficiency

Blended Cost Per Like measures how much you pay for each like on your ads. Meta and TikTok are the platforms that report likes, so only their spend counts.

Formula

Blended Cost Per Like = ( Meta Spend + TikTok Spend ) ÷ Blended Likes

Formula Components

Metric	Definition
Meta Spend	Spend from your Meta ad accounts
TikTok Spend	Spend from your TikTok ad accounts
Blended Likes	Likes on your ads, as Meta and TikTok report them

Metadata
Type	Currency
Data Source	Meta Ads, TikTok Ads
Aggregation	Ratio

Example

Your campaigns ran on all three platforms this month:

Platform	Spend	Likes	Counted in this metric
Meta Ads	$1,500	7,500	Yes
TikTok Ads	$1,000	5,000	Yes
Google Ads	$500	Not reported	No
Blended Cost Per Like	$2,500	12,500	$0.20

Dividing Blended Spend ($3,000) by the same 12,500 likes would give $0.24, charging Google’s budget to likes it didn’t report.

How It Works

Upstack adds Meta and TikTok spend and divides by the likes those two platforms report. Google Ads doesn’t report likes, so its spend is left out. In the app the formula reads Meta + TikTok Spend ÷ Likes. If you run Google Ads, this metric won’t equal Blended Spend ÷ Blended Likes.
