Blended Cost Per Comment: Ad Engagement Efficiency

The cost per comment on your ads. Meta and TikTok are the platforms that report comments, so only their spend counts.

Formula

Blended Cost Per Comment = ( Meta Spend + TikTok Spend ) ÷ Blended Comments

Formula Components

Metric	Definition
Meta Spend	Spend from your Meta ad accounts
TikTok Spend	Spend from your TikTok ad accounts
Blended Comments	Comments 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	Comments	Counted in this metric
Meta Ads	$1,500	85	Yes
TikTok Ads	$1,000	40	Yes
Google Ads	$500	Not reported	No
Blended Cost Per Comment	$2,500	125	$20.00

Dividing Blended Spend ($3,000) by the same 125 comments would give $24.00, charging Google’s budget to comments it didn’t report.

How It Works

Upstack adds Meta and TikTok spend and divides by the comments those two platforms report. Google Ads doesn’t report comments, so its spend is left out. In the app the formula reads Meta + TikTok Spend ÷ Comments. Lower values mean cheaper comments.
