Which consent tool with Google Ads
The consent banner is not only a legal formality: it decides what Google Ads is allowed to measure. Badly configured, it makes very real conversions disappear.
There are two ways to get it wrong, opposite and equally costly. A banner that is too permissive exposes the company to an inspection and a fine. A banner badly wired to Google makes measured conversions collapse, the platform reduces delivery on what was working, and the company loses revenue while believing it is following the rules.
How to choose
Does it handle Google’s consent mode?
This is the decisive technical point. Google expects a precise signal describing what the visitor accepted. A banner that simply blocks tags without sending that signal makes you lose measurement instead of adapting it.
Publisher under European law?
The subject is regulatory before it is technical. A publisher that follows the French authority’s positions and updates its product when doctrine moves saves you from watching it yourself.
Acceptance rate
At equal compliance, wording and presentation change the acceptance rate a great deal, and therefore how much measurement you have. It is a legitimate criterion, as long as it does not lead to misleading practices.
Is it wired across the whole site?
A banner present on the main pages but missing from the checkout protects nothing and distorts measurement exactly where it matters most. Real coverage is checked page by page.
What UNYX does
We install the banner, connect it to Google's consent mode, and check that measurement survives refusals. A badly set banner makes very real conversions disappear.

The questions we get
Do we lose conversions because of consent?
You do if nothing is done about it. Google’s consent mode allows part of what is lost to be estimated. Good implementation limits the damage; none removes it entirely.
Is a free banner enough?
For a simple site, sometimes. The limits appear on automatic tracker inventory, on proving consent in an inspection, and on updates when regulation moves.
Who is responsible in an inspection?
You are, not the banner’s publisher. The tool is a means of compliance, it transfers no responsibility. All the more reason to check what it actually does.
