Blended Cost Per Like: Engagement Efficiency

Blended Cost Per Like measures how much you pay for each like across all your advertising platforms combined.

Formula

Blended Cost Per Like = Blended Spend ÷ Blended Likes

Formula Components

Metric	Definition
Blended Spend	Total ad spend aggregated across all platforms
Blended Likes	Total likes on ads across all platforms

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

Example

Your campaigns generated 12,500 likes with $2,500 total spend across Meta, TikTok, and Google—yielding a blended cost per like of $0.20.

How It Works

Blended Cost Per Like aggregates total spend and total likes from Meta, Google, and TikTok, then calculates the combined cost per like. This gives you a single efficiency metric across all platforms rather than evaluating each separately.
