How fixing broken conversion tracking 5x’d their Google Ads leads
A Melbourne early intervention clinic looked healthy on paper. Hundreds of conversions a month, low cost per conversion. But the phone wasn’t ringing. Here’s what happened when we rebuilt the tracking.

The Challenge
The account looked healthy on paper. Hundreds of “conversions” every month, low cost per conversion, happy reports.
The problem was that none of it was real. Conversion tracking had been set up to fire on page views instead of actual lead form submissions. Every optimisation decision the account had ever made was based on data that didn’t reflect what the business actually needed to know: is the phone ringing?
This is more common than most business owners realise. Tracking breaks silently. A website update, a form change, a tag manager tweak, and suddenly the account is optimising toward the wrong goal without anyone knowing.
The Solution
Step 1: Fix the foundation before touching anything else
Before adjusting bids, keywords or budgets, we rebuilt conversion tracking from scratch. Audited every conversion action, implemented proper form submission tracking, verified data was flowing correctly into Google Ads, and set sensible attribution windows.
The immediate result of doing this properly was that reported “conversions” dropped from hundreds a month to a handful. That’s the moment a lot of advertisers panic and revert to the old broken setup because the numbers look bad. This client didn’t, because we’d explained exactly what was happening. The leads weren’t disappearing. We were finally seeing reality.
Post-fix reality: 4 to 5 real leads per month at a cost of $344 to $448 each.
Step 2: The second break
Just as things stabilised, conversions dropped again. The web developer had modified the contact form without letting anyone know, which broke the tracking we’d just fixed. Fixed again within 48 hours.
Lesson: conversion tracking is not set and forget. Anything that touches the website can break it silently.
Step 3: Optimise with real data
Once we had clean, trustworthy data flowing, we could actually make informed decisions:
- Campaign structure: clean, location-based campaigns split by suburb group (one for the eastern suburbs, one for the western suburbs, plus a brand campaign)
- Keywords: highly targeted, therapy-specific terms with local intent
- Bid strategy: Max Conversions, this time with accurate conversion data to feed the algorithm
- Philosophy: keep it simple, no over-complicated structures
Full Case Study
The story in one chart
Same account. Same operator. Roughly the same monthly budget. What changed was that we could finally see the truth.
What happened month by month
September and October 2025 were the first two clean months after the tracking rebuild. Four leads, then five. That’s the real baseline. From December onwards, the numbers climbed as Max Conversions bidding started learning from accurate data instead of noise, and account structure was tightened around what was actually working.
Cost per lead followed the same curve
$448 CPL in October. $55 by December. It has drifted up slightly in more recent months as monthly spend increased, but sits well below the pre-rebuild baseline. Honest reporting matters here: we haven’t cherry-picked a peak month, we’ve shown the full ten-month window since the rebuild.
Key takeaways
1. Fix your tracking before you optimise anything
You cannot optimise what you cannot measure. If your tracking is wrong, every bid change, keyword decision and budget shift is a guess. Broken tracking leads to broken decisions.
2. Conversion tracking breaks silently
Website updates, form changes, tag manager edits, any of these can break tracking without warning. Build in regular audits. The account will keep running while it feeds on bad data, and you won’t know until someone notices the phone isn’t ringing.
3. Don’t panic at the drop
When you fix broken tracking, reported numbers will fall. That’s not a crisis, it’s clarity. The leads were never there. You just couldn’t see the truth.
4. Simple structures win
Clean, location-based campaigns with tightly targeted keywords outperform complex, sprawling structures every time. Complexity creates places for budget to hide.
5. Real data enables real optimisation
Once tracking was accurate, standard optimisation practice delivered exceptional results. The magic wasn’t fancy tactics. It was having data you could trust.
The bottom line
This clinic went from spending its budget on phantom conversions to generating 5x more real leads at roughly a fifth of the cost per lead. The transformation didn’t require anything exotic. It required accurate measurement and disciplined execution.
The foundation matters more than the tactics.
