Summary here
Step 1 · Tracking audit
Finally know if your data can be trusted.
I review your Google Tag Manager setup, GA4, ad conversions and consent. You get the list of errors, their impact and a prioritised action plan.
- E-commerce
- SaaS
- Lead generation
- Agencies
Who is it for?
Does any of this sound familiar?
Numbers don't match
GA4, Google Ads, Meta and your back office don't show the same sales or leads.
Conversions are missing
Some sales or form submissions aren't tracked, or are counted twice, and your campaigns optimise on bad data.
Your GTM is a mess
Tags piled up over the years and across vendors, with no consistent naming or documentation.
Unsure about consent
You don't know whether your tags respect visitors' choices or whether Consent Mode V2 is properly set up.
What you get
A clear, actionable diagnosis.
The audit is more than a list of problems: each point is explained, its impact assessed and its fix prioritised.
- Full review of your Google Tag Manager container: tags, triggers and variables
- GA4 data collection check: events, conversions and e-commerce data
- Ad pixels and conversions check (Google Ads, Meta, TikTok…)
- CMP, cookie banner and Consent Mode V2 check
- Written report: errors found, impact and priority level
- Prioritised action plan, usable by you, your agency or me
- Video debrief to answer all your questions

« I have worked with Lucas many times on various data collection and performance tracking issues. His technical expertise is impressive, but above all very well explained, which makes exchanges simple and efficient even for non-technical profiles. The tracking setup (GA4, GTM, events, conversions, consent, etc.) is carried out with great rigour and precision. Beyond his technical skills, I particularly appreciated his responsiveness, his teaching approach and his professionalism. He takes the time to understand the business stakes and always suggests relevant, tailored solutions. I highly recommend his services to any company that wants to improve its analytics tracking and data quality. »

« Great experience with Lucas! In less than a week, he overhauled my entire tracking system across my three sites. He even went above and beyond by sending me an explanatory video at the end. I recommend him 100%. »

« I had the opportunity to work with Lucas on a tracking issue related to duplicate purchases on Meta, as well as an inconsistency in the number of additions to the cart. Faced with this situation which seriously impacted my analysis on Meta, Lucas demonstrated a quick understanding of the problem, he quickly identified its origin and immediately resolved it. It was a real pleasure to work with Lucas, I highly recommend him for his expertise, his professionalism and his responsiveness. Thank you! »

The price depends on the number of websites, tools and journeys to check. After a first call, I send you a fixed quote.

What if I want you to fix the errors?
That’s what the Implementation service is for: the audit’s action plan becomes the roadmap.
