Founder, Taglert
I build and run Taglert, a tracking health monitor for agencies and freelance media buyers. It watches Meta pixel health, Conversions API event match quality, duplicate events and Google Ads conversion tracking across every client account you connect, checks them every 30 minutes, and emails you when one of them breaks.
Everything here comes out of that work. When a pixel stops firing or a conversion action goes unverified, nothing turns red: the campaign keeps spending and the first person to notice is usually the client. These posts are the diagnostics for that problem, written in the order I needed them.
I write about what I can check. Where a claim comes from a platform's own documentation, the post links the documentation rather than someone else's summary of it, and where something is a judgement call I say so instead of dressing it up as a rule.
Corrections and arguments are welcome at support@taglert.app. If a post here is wrong, I would rather fix it than leave it up.
How these posts are written
Taglert is one person, and the posts here are drafted with AI assistance and then edited, fact-checked and published by me. I am responsible for every claim on this blog. See the editorial process for the detail.
