The conversions consent hides,
modelled back into your reports.
When a visitor declines, the sale they make falls out of GA4 and Google Ads. Velo passes the four Consent Mode v2 signals the way Google expects, so the conversions you cannot see are estimated from the traffic that did consent, not dropped.

Why a decline no longer means a lost sale
Modelling only works when Google receives the right signals first. Velo handles the three things that make a declined visitor recoverable.
Four signals, passed right
Velo reads each visitor's choice and sets all four Consent Mode v2 flags the way Google expects, in real time, with no manual tag edits.
Declines still modelled
A cookieless ping still fires on a reject, so Google can estimate the conversion that consent would otherwise erase from your reports.
Bids on the full picture
With the modelled conversions counted, Google Ads optimises on every sale, not just the slice that happened to opt in. The same spend works harder.
Four signals turn a decline into an estimate
We use cookies to measure traffic and improve your experience.
The visitor declines
They tap reject, and your advertising tags stay blocked, exactly as the law requires. With most consent tools, the sale that visitor makes now disappears from GA4 and Google Ads for good.
Velo passes the four signals
Even on a decline, Velo sends Google the exact state of all four signals and a cookieless ping. Nothing personal moves, but Google now knows a choice was made and that a conversion happened behind it.
Google models the conversion
From those signals and your consented traffic, Google estimates the conversions consent hid and adds them back to your reports. Your campaigns optimise on what really happened.
The four signals, set right on every visit
Consent Mode v2 turns on four flags: analytics_storage, ad_storage, ad_user_data and ad_personalization. Velo reads each visitor's choice and sets all four correctly, the moment they decide, with no manual tag edits. That is the whole reason Google can model what a decline would otherwise erase.
How Consent Mode v2 worksaverage ROAS lift once the modelled conversions come back.
On a typical site, 34% of sessions sit behind the banner. When the conversions they make are modelled and counted, Google Ads bids on the full picture instead of the slice that consented, and most sites recover 20 to 40% of the conversions they were quietly losing.
Figures are measured ranges across Amplio Data client implementations, not a guarantee. Recovery depends on your traffic mix, regions and how your tags are configured. Modelled conversions are estimated by Google, not invented by Velo.
An estimate from Google, not a number we invent
Modelled conversions are Google's calculation, not Velo's. We pass the signals the way Google expects, and Google estimates the conversions consent hid from your consented traffic. We never write a figure into your reports. Treat the result as a measured estimate that closes the gap, not a guarantee.
Read the developer docsWhat still reaches Google on a reject
A decline blocks the cookies, not the signal. These are the cookieless inputs Velo keeps flowing so the model has something to estimate from.
Stop losing the sales you already earned.
Add the Velo template to your Google Tag Manager and the four signals stay right on every page, in every region. Declined conversions get modelled back, with nothing to maintain by hand.
Modelled conversions, answered
What are modelled conversions?
They are Google's estimate of the conversions that happened behind a decline, calculated by Google from your consented traffic and the four Consent Mode v2 signals Velo sends. When a visitor rejects, the sale is no longer dropped. Google models it back into GA4 and Google Ads instead.
How does Velo make modelling possible?
Modelling only works when Google receives the right signals on every visit, including declines. Velo passes analytics_storage, ad_storage, ad_user_data and ad_personalization the way Google expects, plus a cookieless ping on a reject, so Google has the inputs it needs to estimate. See how it fits together on the Consent Mode v2 page.
Are modelled conversions real conversions?
They are Google's estimate of conversions that genuinely happened but were hidden by a decline, not invented numbers. Velo does not write any figure into your reports. Treat them as a measured estimate that closes the gap, not a guarantee.
How many conversions can I expect to recover?
On a typical site, 34% of sessions sit behind the banner, and most sites recover 20 to 40% of the conversions consent was hiding once the signal comes back. The exact number depends on your traffic mix, regions and how your tags are configured.
Do I have to edit my tags?
No. You add the Velo template to your Google Tag Manager once, and your existing tags read consent automatically. There are no per tag consent checks to write or maintain by hand.
How long does it take to go live?
Full setup runs inside 72 hours. The template drops into Google Tag Manager in minutes, and everything else is configured in the dashboard without touching the snippet again.
