Consent Mode and cookies
Consent Mode v2 and a cookie banner where consent travels the whole way
Consent Mode v2 is the link between your cookie banner and your tracking, and without it you lose both data and features in Google Ads. I test hands-on in the browser what really happens with and without consent, then fix the technical side; I have done that review many times across 400+ projects.

Consent Mode and cookies
How banner and tracking fit together
A cookie banner is only the visible layer. Beneath the surface, the user's choice has to be translated into signals that the tag setup actually obeys, and that is where things most often go wrong. If the banner is a detached element with no link to GTM, nothing happens no matter what the user clicks. And a banner that blocks everything by default was configured, not designed; someone just switched it all off and moved on.
Consent Mode v2 is Google's format for exactly those signals. On refusal Google receives anonymous pings without identifiers, used to model conversions, and on consent measurement runs normally. The format is also a requirement if you want remarketing and full conversion data in Google Ads for European users.
What I review and set up
- Whether cookies get set before the user has made a choice; the single most common failure.
- Whether declining is as easy as accepting. That is a requirement, and it is often not met.
- Consent Mode v2 with all four consent signals correctly wired to the banner and GTM.
- The interplay with GA4, Google Ads and Meta, including what may fire on refusal.
- Scripts and embedded content outside the tag manager that the banner has no hold on.
- Whether the cookie policy describes the cookies actually being set.
Measurement beyond consent
The rules do not have to mean blindness. Anonymous, cookieless statistics are allowed without consent when they cannot recognise individuals, and they give a reliable picture of traffic and content.
I am happy to set up such a base measurement next to the consent-based one. That gives you a point of comparison, and you can see what share of your visitors actually decline; few people know that number for their own site.
What you get
Concrete deliverables, not a report of recommendations someone else has to find time for.
- A technical review of the banner
Browser testing of what gets set when, with and without consent, collected in a list of findings and fixes.
- Consent Mode v2 configured
All four consent signals wired from banner through GTM and on to Google, verified signal by signal.
- An accurate cookie overview
An updated list of the cookies the site actually sets, as the basis for your cookie policy.
- A cookieless base measurement
Anonymous statistics alongside the consent-based ones, so you can see the refusal share and have numbers to compare with.

How it works
Four steps. You know what happens when, and you can stop after any of them.
- 01
Audit of the current setup
Using preview mode and the network log, I work out which tags fire, which fail, and where the same purchase gets counted more than once. The result is a concrete list of what has to go and what is missing.
- 02
A new structure in GTM
The container is rebuilt with consistent naming and a clean data layer, so anyone can open it a year from now and understand what happens. Old tags are archived rather than deleted, so nothing is lost.
- 03
Server-side and consent mode
I set up a server container on your own subdomain and wire in consent mode, so the consent choice controls what gets sent. Conversion tracking for Google Ads and Meta moves over with it.
- 04
Checked against order data
For a period after launch, I compare orders in your backend with the numbers in GA4 and the ad platforms. Deviations are explained in writing, so you know how much weight the numbers can carry.

Frequently asked questions
- What does setting up Consent Mode v2 cost?
- It depends on the starting point. The price is affected most by which cookie banner you have, how many domains and languages need covering, and how much of the existing setup needs fixing. Tell me which banner and which Google tools you use, and you get a concrete quote with a same-day reply.
- What is the difference between basic and advanced Consent Mode?
- In the basic variant Google's tags do not load at all before consent, and Google receives nothing on refusal. In the advanced variant anonymous cookieless pings are sent on refusal, which Google uses to model conversions. Advanced gives a better data foundation, but the choice between the two should be made deliberately, ideally with your legal adviser.
- Do you help with Consent Mode outside the capital area?
- Yes, all over Denmark. I am based in Herlev near Copenhagen, and jobs for businesses in Aarhus, Odense and Aalborg are handled remotely with screen sharing; the setup lives in the browser and in GTM anyway.
- Are we GDPR compliant once Consent Mode v2 is set up?
- Not automatically. Consent Mode v2 is a technical standard for passing consent signals to Google; it replaces neither a correct cookie banner, an accurate cookie policy nor your other GDPR obligations. I make sure the technology does what it should and document it, but the legal assessment has to come from a lawyer or DPO.
- Which cookie banner should we choose?
- It depends on the need, and I have no partner deals colouring the recommendation. With one site and few third parties a simple solution is plenty; with many domains, languages and documentation requirements a larger platform makes sense. If you already have a banner that can send Consent Mode signals, we usually keep it.
- Do we lose data by setting it up correctly?
- Some, yes; visitors who decline may not be measured individually, and a correct setup has to reflect that. In return the remaining data becomes something you can safely build decisions on, Google's modelling fills part of the gap, and a cookieless base measurement can show the overall picture.
- Can you test whether our current setup holds water?
- Yes, that is a bounded and quick job. I go through in the browser what gets set when, both with and without consent, and collect the findings in a list with recommendations. Most people are surprised by at least one item.
