eCommerce Tracking That Feeds Google's Bidding Real Revenue, Not Guesses
Smart Bidding is only as smart as the data it's fed. We rebuild your GTM container, wire GA4 purchase events with true order values, and add Enhanced Conversions on first-party data. That's the data layer of MaxV™, and it's what tROAS bids on.

When GA4 and Google Ads don't agree, your bids pay for it
Google's tROAS bidding sets bids from the conversion values it gets reported. When those numbers are wrong, the algorithm raises bids on the wrong products and starves the right ones. The waste hides inside reports that look fine.
Purchase counts that don't match
GA4 reports one number of sales, Google Ads reports another, and nobody can say which one is right.
Order values missing or doubled
Revenue shows up blank on some purchases and counted twice on others, so your ROAS reads wrong.
Conversions dropped by privacy limits
Browser and iOS privacy changes quietly cut conversions that did happen but never made it back to Google Ads.
Smart Bidding optimizes to the wrong number
tROAS can only bid on what it's fed. Feed it inaccurate values and it pours budget into the wrong products.
Wasted spend you can't see
The reports themselves are wrong, so the misallocated budget never shows up as a problem to fix.
GTM, GA4, Enhanced Conversions, in that order
Rebuild your GTM container
We audit every tag in your container and rebuild it as one source of truth. Dead tags get removed. You stop wondering which tag is firing and which one is lying.
Wire GA4 events with real values
We set up GA4 ecommerce events so every order is counted once, in the right currency, with its true purchase value. No duplicates, no missing revenue. Your numbers start matching reality.
Add Enhanced Conversions, then hand off to tROAS
Enhanced Conversions sends hashed first-party checkout data to Google Ads, recovering conversions browser privacy limits would otherwise drop. Once the data is trusted, it feeds value-based bidding. That handoff is where the full eCommerce Google Ads program this data layer powers takes over.
What gets built, verified and reconciled
A clean GTM container you can trust
Your Google Tag Manager container gets rebuilt and governed, so duplicate tags and silent misfires stop corrupting what gets sent to Google.

The full ecommerce path, from view_item to purchase, is wired with true order values. Your reports show what each sale was actually worth.
Get my tracking quote →Enhanced Conversions, checked end to end
Hashed first-party data from your checkout flows to Google Ads, then gets diagnosed so it recovers conversions that browser privacy limits would otherwise drop.
Get my tracking quote →Know which number to bid on
GA4 and Google Ads count conversions differently, so they rarely match. You get the two reconciled and a clear answer on which figure tROAS should bid against.

Hitchweb, auto parts
The rebuilt data layer became the foundation the campaign stack was built on.
Revenue grew 25% year over year on an account running this stack. See how the auto parts campaign stack used this data. [CONTENT NEEDED: one tracking-specific detail, e.g. what was broken before the rebuild.]
Beautysense, beauty and cosmetics
With purchase events and true order values wired first, the bidding had real revenue to work from.
ROAS rose over 300% on an account running this stack. See the beauty eCommerce campaign side. [CONTENT NEEDED: one tracking-specific detail, e.g. one before/after data point.]
How to read these
Tracking was the foundation, not the sole cause.
Both results come from accounts running the MaxV™ data layer. The campaigns did their part. Clean data is what let the bidding trust the numbers.

Tracking and attribution, answered straight
Why do GA4 and Google Ads report different conversion numbers?+
They count conversions on different rules. Google Ads credits the conversion to the day of the ad click and uses its own attribution model, while GA4 credits the session of the purchase under a separate model and reporting window. Same purchases, two counting methods, two totals. The fix is to reconcile them and decide which number your bidding should trust.
What is Enhanced Conversions, and is my customer data safe?+
Enhanced Conversions sends hashed first-party customer data from your checkout to Google Ads, recovering conversions that browser privacy limits would otherwise drop. The data is hashed before it leaves your site, and it is Google's own product built on first-party data you already collect at purchase.
Do I need my developer involved?+
Usually very little. Most of the build happens inside Google Tag Manager, which minimizes changes to your site code. Some platforms need a data layer snippet added so order values pass through cleanly. When that's the case, we scope exactly what your developer touches before anything starts.
Will fixing tracking alone improve my ROAS?+
Honestly, no. Clean tracking makes tROAS bid on real revenue instead of guesses, so your spend stops chasing wrong numbers. The campaigns still have to do the work. Clean data is the foundation the campaign side stands on, and that side lives on the full eCommerce Google Ads program this data layer powers.
What does the engagement cost?+
A flat retainer with no contract. The exact quote depends on your platform and the state of your current setup, so we price it after we've seen what's in front of us. No contract means the data has to keep proving itself every month. Get my tracking quote.
