Blended Cost per Lead: Cross-Platform Lead Acquisition Cost

Blended Cost per Lead measures how much you spend on average to acquire a single lead across all advertising platforms combined.

Formula

Blended Cost per Lead = Blended Spend ÷ Blended Leads

Formula Components

Metric	Definition
Blended Spend	Total advertising spend across all connected ad platforms
Blended Leads	Total lead conversions attributed across all ad platforms

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

Example

Your business spent $5,000 across all ad platforms last month and generated 250 leads.

Metric	Value
Blended Spend	$5,000
Blended Leads	250
Blended Cost per Lead	$20.00

At $20 per lead, you can evaluate whether your cross-platform lead generation strategy is cost-effective compared to industry benchmarks or your target acquisition costs.

How It Works

Blended Cost per Lead aggregates total advertising spend from Meta, Google, and TikTok, then divides by the total number of leads attributed to those platforms. This provides a unified view of lead acquisition efficiency without platform-specific silos.
