Meta pixel not working? Find out before your client does
A Meta pixel that is not firing, not active, or not showing in Ads Manager rarely announces itself. The dashboard keeps showing conversions while the budget spends on bad data. Taglert monitors your Meta pixels across every client account and tells you the moment one stops firing.

Why your Meta pixel is not working: the four things that break
A pixel that is technically installed can still be losing you conversions. "Not working" almost always turns out to be one of these four, and Taglert watches all of them:
- Pixel not firing or not active. Catches a pixel that has stopped firing or gone inactive — the state Ads Manager reports as “your Meta pixel is not active” — before your client notices results slipping.
- Event Match Quality (EMQ). Alerts you when Conversions API match quality drops, since low EMQ quietly weakens optimization and attribution.
- Duplicate events. Flags when browser and server events stop deduplicating, which inflates your numbers and misleads the algorithm.
- Pixel not tracking purchases. Confirms the purchase and lead events you actually optimize for are still recording, not just PageView.
What a pixel that stops tracking purchases costs you
Broken tracking keeps spending your budget against a signal that stopped being true, and it never throws an error. See what that looks like on your own spend:
$6,667 of that is only at risk because nobody was watching.
Across 5 accounts you are responsible for $50,000/mo, all of it optimised against conversion data nobody has verified today.
What correct setup is worth, in their words: Meta's Dataset Quality API documentation reports a median 32.9% more Search conversions attributed when the Conversions API runs alongside the pixel, and Google treats an enhanced conversions match rate below 15% as low.

How to check if your Meta pixel is working
Meta pixel monitoring FAQ
What is Meta pixel monitoring?
Meta pixel monitoring is the ongoing checking of your Meta (Facebook) pixel to confirm it is still firing and recording conversions. Pixels break quietly after site updates, plugin changes, or consent-tool changes, and the ad dashboard keeps showing numbers, so monitoring catches the break before it costs you.
Why is my Meta pixel not working?
The clearest sign is that your reported conversions stop matching real sales in your store or CRM. Common causes are a site or theme update that dropped the pixel, a plugin or tag manager change, a consent tool blocking it, or a checkout that moved. Other signs include a pixel that has not fired in over a day, a sudden drop in event volume, or Event Match Quality falling. Taglert checks all of these automatically so you do not have to remember to look.
What does “your Meta pixel is not active” mean?
Meta marks a pixel inactive when it has not received events for a stretch of time. It usually means the pixel is no longer firing on the site at all, rather than that something is wrong inside Meta. Because the warning only appears if you go looking in Events Manager, the spend keeps running in the meantime, which is the gap Taglert closes by alerting you the same day.
Why is my Meta pixel not showing in Ads Manager?
Usually the pixel exists but is not connected to the ad account you are looking at. It may sit in a different business portfolio, it may not have been shared with that ad account, or your user may not have permission on the dataset. A brand-new pixel that has never received an event can also look missing. Check the dataset's assigned ad accounts in Events Manager first.
How do I check my Event Match Quality score?
Event Match Quality is shown per event in Meta Events Manager, under the dataset's event breakdown. It scores how well the customer information you send matches Meta's records. Checking it by hand means opening each dataset for each client, which is why Taglert tracks EMQ continuously across every connected account and tells you when it drops.
Can Taglert monitor multiple client accounts?
Yes. Taglert is built for agencies and freelance media buyers who manage many accounts. You connect each client's ad account once, and Taglert checks them all around the clock from one dashboard.
Does it monitor the Conversions API and Event Match Quality too?
Yes. Beyond basic pixel activity, Taglert monitors Conversions API Event Match Quality (EMQ) and duplicate events between the browser pixel and the server, since those quietly weaken performance even when the pixel is technically firing.
How fast will I know when a pixel breaks?
Taglert checks every connected account continuously and emails or Slacks you when something breaks, so you find out the same day instead of at the next monthly report.
Do I need to install any code?
No. You connect your Meta ad account through Meta's secure login. There is no snippet to add to a client's site and no code to maintain.
Isn't this the same as Meta's built-in pixel alerts?
Meta can email you about some pixel issues, but only for Meta, and only one account at a time. Taglert watches every client account in one place, covers Google Ads conversion tracking too, and gives you one dashboard and consolidated alerts instead of digging through each account's settings. For an agency managing many accounts, that is the whole point.
Never lose a client to a broken pixel again
