If you have 2 CAPI solutions active simultaneously, you're destroying ad performance ⚠️
At the end of this post, I'll show you an example of this.
Duplicate CAPI setups happen so frequently these days bc many SAAS tools now offer server-sided tracking:
- Blotout, Elevar, Popsixl
- Shopify <> Meta CAPI
- Triple Whale & Northbeam
- Angler
... the list goes on!
Typically a brand is signed up for more than one of the above concurrently (for diff reasons) & ends up turning on CAPI integration for each rather than select ONE (and ONLY one).
This often goes undiagnosed by brands and marketers. It makes performance look BETTER in-platform since conversions are duplicated.
In reality?
Business performance & 3P measurement tank.
It's a hidden parasite.
Most marketers don't even know how to diagnose when this is happening to their brand.
So, how do you know if you have more than one CAPI firing? 👇
Whenever you see a significant gap between browser and server events, you likely have two CAPIs firing.
When this happens, you have the same event getting sent back to Meta from 2 diff sources which instantly crushes your Event Match Quality (EMQ) score.
Bc these SAAS companies don't communicate, events aren't properly deduplicated.
So what's the actual impact of a lower EMQ score?
In the image below, you'll see an example where a 2nd CAPI was activated on July 17.
Immediately following this, EMQ tanked below a 6/10.
Each event was impacted similarly, but for illustrative purposes below I only included the "View Content" event.
Immediately following the EMQ decline, Triple Whale ROAS tanked at the same rate (platform-reported ROAS erroneously perceived to improve bc of the duplicate events).
On July 23 we identified the duplicate CAPI & shut it off.
EMQ (and thus TW ROAS) immediately rebounded, as expected.
This is why we start every audit with the basics:
EVENTS MANAGER.
Garbage in, garbage out.
Without event health in place, you're feeding AI/ML trash. Your performance will be limited.
Events manager is not a sexy place to spend your time.
But you MUST master it and have a pulse on EMQ at ALL TIMES.
It's usually the place where all the hidden issues live.
