What VERA is
VERA is a free GA4 companion for the moment you stop trusting your events. You paste the events you expect and the URLs they should fire on; VERA fetches each page once and checks whether the event name and any tagging context are actually in the live source.
No GA4 login, no OAuth, no account access. Public HTTP only.
What it checks
- Whether the event name appears in the live HTML — quoted (a real call) or loose (a mention).
- Whether the page carries tagging context at all — dataLayer, gtag, a container or a measurement ID.
- A short evidence snippet so you can see why the verdict landed where it did.
- Whether you flagged the event as a key event, so the ticket order makes sense.
How we judge
- FOUND — the event name appears quoted, on a page with tagging context.
- WEAK — the name appears, but loosely, or without clear tagging context. Verify before you trust it.
- NOT_FOUND — the name isn't in the source at all on that URL.
- FETCH_ERROR — the page couldn't be fetched, so nothing is claimed.
An honest limit: source scanning can't see events fired later by a tag manager, a consent gate or client-side routing. FOUND is evidence, not proof — DebugView and Realtime are still the last word.
How to run a check
- 01Sign in with your email — one-tap link, no password.
- 02Paste your event names (mark the key events), or load the nikkos.io example.
- 03Paste the URLs those events should fire on.
- 04Hit Run, filter by verdict, then export CSV.
Turning results into a ticket
- NOT_FOUND on a key event → tracking ticket for Eng, one event per row.
- WEAK rows → verify in DebugView before anyone reports on them.
- Events found nowhere across every URL → the event doesn't exist; stop reporting on it.
Caps: up to 30 events and 20 URLs per run, one fetch per URL.
