Use Cases / Lead-tracking break
GA4 · QACatch a lead-tracking break before it costs a week of ad spend.
The tracking didn't error. It just stopped counting — and the media team kept optimising toward a number that was now a lie.
The situation
What actually happens
- A brand ships a redesigned enquiry form on a Tuesday.
- The new form doesn't record the conversion the way the old one did.
- GA4 keeps reporting — just fewer leads. No alert. The daily number looks like normal variance.
- Paid Search keeps bidding to a signal that's now under-counting by 60%.
- Nine days later the client asks why cost-per-lead doubled. Now it's a fire.
With ODDVX
The same week, instead
The overnight check runs
ODDVX watches every brand's lead and purchase events against their own history. This one normally fires many times a day, so a single quiet day is already a red flag.
You get the alert Wednesday morning
Ranked most-urgent first, with a plain-English reason and a file you can forward straight into the client thread.
A test confirms the cause
Point ODDVX at the live form. It submits a test enquiry and reports the conversion failed — so you know it's the site, not the analytics config.
Dev fixes it, you re-run
Same test, clean pass, confirmation page included. Sign-off in an hour — not a post-mortem in a fortnight.
