Meta and Google Both Claimed the Same Sale. Who Actually Generated It?

A customer sees a Meta ad on Tuesday.

On Thursday they search your brand and click a Google ad.

On Friday they receive an email.

On Saturday they type your URL directly and buy.

Who gets the sale?

Depending on attribution settings, several platforms may make a perfectly plausible claim.

The business only received one order.

This is not necessarily a data error

Each platform observes a different part of the journey. Its optimisation system needs to know which conversions appear connected to its activity.

The problem starts when the business adds every platform's attributed revenue together and treats the result as economic truth.

The closer a channel sits to purchase, the easier it is to claim credit

Branded search, email and retargeting often interact with people who already have substantial intent.

Awareness activity can influence the journey earlier and receive less obvious credit.

Neither observation tells you what you should spend. It tells you attribution needs context.

Multichannel makes this even harder

I have worked in environments where physical mail, website, email, search, social and affiliates all interact with the same customer base.

Trying to force every order into a single neat marketing bucket can create more confidence than accuracy.

What I would do instead

Use multiple lenses:

• platform reporting for campaign optimisation
• analytics for cross-channel journeys
• finance/commerce data for actual revenue
• blended efficiency for overall economics
• experiments or holdouts to test incrementality
• new-customer and customer-lifetime measures where useful

No single report solves attribution.

The aim is a decision system robust enough that you do not double-count success and then wonder why the bank account disagrees with the dashboards.

Meta says it generated the sale and Google says it did too — I can help you build a decision system that does not depend on a single platform being right.
