Why is Meta Events Manager showing a low event coverage rate?
A low event coverage rate in Meta Events Manager usually means the same event is being fired by PixelFlow and by another Meta Pixel setup on your site.
PixelFlow already loads your Meta Pixel and Conversions API together with deduplication. If your website is also loading the Meta Pixel through Google Tag Manager, a native platform integration, or another script or plugin, Meta can flag the setup as low coverage or duplicate tracking because another script is generating events too.
Before you change anything, check your Events Manager diagnostics and compare them with your PixelFlow event logs. That will usually confirm whether another source is sending the same event.
How to fix low event coverage
Check whether your Meta Pixel is loaded anywhere outside PixelFlow.
Remove or disable any extra Meta Pixel script, plugin, app, or integration.
Republish your site if your platform requires it.
Wait for Meta to reprocess the diagnostics after the duplicate source is removed.
Places to check first
Google Tag Manager
If you use Google Tag Manager, check whether it is loading your Facebook Pixel.
If it is, remove that tag or stop it from firing. Keep PixelFlow as the only source sending your Meta Pixel events.
Website platform integrations
Open your platform settings in Webflow, Squarespace, Framer, or your website builder and look for a native Meta Pixel or Facebook Pixel integration.
This is often under Apps & Integrations or a similar settings area. If Meta Pixel is turned on there, turn it off.
Meta Events Manager automatic tracking
Meta can also create duplicate events through its own automatic tracking tools.
Open Meta Events Manager.
Select your dataset.
Click Settings.
Find Track events automatically without code.
Turn it off.
What to do next
After you remove duplicate Meta Pixel sources, recheck your diagnostics in Meta and confirm that events are only being sent once.
