Over-attribution
Fix over-attribution on Meta & Google Ads

Organic, App, Draft and POS orders handled correctly - across both Meta and Google.

Problem
Why does over attribution happen?
There are two main sources of over attribution on Meta / Google are - Source Contamination and Event Duplication
Source Contamination
Meta and Google can't handle complex marketing setups on their own. If you are running WhatsApp, Email, Affiliates, App or have a large share of Organic orders - all these orders will also feed the same Shopify data layer that Meta and Google are tracking.
As a result, orders that never came from ads - get credited to them.
Event Duplication
Conversion API make it possible for any 3rd-party tool to start sending events on your behalf.
Unfortunately, most brands end up trying a combination of these without looking at the long-term impact. So a brand might be using the Facebook and Instagram sales channel app with CAPI turned on, plus CAPI running from the third-party checkout and also CAPI running from their app, resulting in multiple data streams going into the same pixel.
This problem is compounded even further when you have legacy pixels or scripts that are tracking and firing events to your Meta pixel.

Impact
Your ad platforms are optimizing on noise
If Orders that never came from ads get credited to them, or individual orders get counted multiple times.
The real impact of Ads is never measured. Basically, your Ads are optimising on randomized data that doesn't match what your Shopify actually shows.
Organic orders inflate ad numbers
Sales from organic, direct and referral get credited to Meta and Google, making paid performance look better than it is.
App and POS orders get misattributed
When a linked app or an offline POS runs alongside the Shopify store, those orders leak into the platforms' conversion counts.
10–15% of conversions go missing
Without server-side tracking, browser and privacy loss drops real conversions the platforms never get to learn from.

Solution
A clean data flow, end to end
The BooleanMaths tracking setup composes of three layers so every Ad platform sees only real, qualified conversions - each assigned to the channel that actually earned it.

Track
Server-side tracking
Every conversion is captured server-side, recovering the 10–15% that browser tracking loses.
Nothing real slips through the cracks.
