Notes on consent
and signal recovery.
Field notes from the team that fixes tracking for a living. Plain explanations of how consent works, what Google actually expects, and where the conversions go when a banner gets it wrong.
How to pass the consent signal to a server side tagging container
There is no second integration: the state rides to the server on the request itself. Six steps to wire it, plus the failure that survives a correct setup, where the gate holds and the container hands the vendor an identifier anyway.
Consent Mode v2How to check your cookie banner is sending the Consent Mode v2 signal
Six checks in about ten minutes. Read all four signals in the browser before you touch the banner, then read what actually reached Google on the request, and know which of the two can see the half of the signal version 2 added.
Signal recoveryCan Google Analytics work without cookies
Yes, and in a narrower sense than most people mean. The event still reaches GA4 without a cookie. What disappears is the identifier that ties two hits to one person, and with it every report built on continuity.
Consent Mode v2Do you still need a cookie banner with server side tagging
Server side tagging moves your tags onto a server you control. It does not move the moment of consent, and it does not remove the duty to ask. Here is what actually changes, and where a first party setup quietly breaks.
DebuggingWhy your GA4 traffic shows as Unassigned after adding a cookie banner
Three different problems wear the same label. One is the honest cost of a late acceptance. The other two are wiring, and one of them is a server side setting quietly undoing the denial it was built to respect.
GuidesWhite label cookie consent for agencies: what actually matters
Every agency plan sells the branding, so it is not the decision. Who is named on the consent record, whether one client's log can leave on its own, and whether the signal ever reaches their tags.
Getting startedWhat is Global Privacy Control, and do you have to honour it
A browser signal that says do not sell or share my data, binding in most US states with a privacy law. What it is, where it overrides a stored acceptance, and why it should not switch your analytics off.
GuidesDo cookie banners slow down your website
The banner script is rarely the expensive part. The cost lands when someone accepts and the whole tag stack initialises at once, on the one path your PageSpeed score never loads.
GuidesHow to raise cookie consent accept rates without dark patterns
Plain language, equal buttons, granular categories and a banner that renders instantly lift accept rates on their own. And with Consent Mode v2 wired, the tricks are not just risky, they are barely worth anything.
Getting startedDo you actually need a cookie banner on your website
Almost certainly yes, if you set non essential cookies and have visitors under a consent law. But that is only half the answer. The half the checklists skip is whether the banner will quietly cost you your analytics.
Signal recoveryWhat happens to your GA4 data when users reject cookies
Nothing at all, if your tags never fire. A cookieless ping, if they do. What GA4 keeps, what it quietly loses, and the part of the gap modelling never fills.
GuidesWhat is a consent management platform (and when do you need one)
The banner is the part visitors see; the platform is the whole engine behind it. What a CMP actually does, and the second job most definitions skip.
Consent Mode v2Basic vs advanced Consent Mode: which one are you running
Deny consent in an incognito window and watch the Network tab. A request that still fires means advanced; an empty panel means basic, or a broken tag.
GuidesHow to install a cookie banner with Google Tag Manager
The banner has one job in Tag Manager: set the consent state before your other tags fire. The trigger that guarantees it, and the two checks after.
Signal recoveryHow to recover the conversions your cookie banner is costing you
When a visitor rejects cookies you lose the attribution, not the visit. The exact order to wire consent so Google models the missing conversions back.
Signal recoveryWhere 34% of your sessions actually go
On a typical site, a third of visitors sit behind the banner and never reach your reports. What happens to that traffic.
Consent Mode v2A plain English guide to Consent Mode v2
What the four signals mean, why basic and advanced are not the same thing, and how to tell which one you are actually running.
DebuggingWhy your GA4 conversions dropped overnight
A banner change, a tag that fires too early, a region rule that flipped. The usual suspects when the numbers fall and nobody touched the campaigns.
OpinionReject all should be one click, here is why
The design choice regulators keep flagging, what a fair banner looks like, and how a clearer first view tends to lift consent rather than lower it.
