Consent Mode V2 And Your Conversions
When a visitor refuses cookies, their conversion leaves standard measurement. Set your refusal rate, your volumes and your mode: the tool splits your conversions into those measured, those Google can model without cookies, and those left out.
Consent Mode passes the choice made in your cookie banner on to Google. Version 2 adds two parameters, ad_user_data and ad_personalization, to the original two. In advanced mode, tags send cookieless pings when the visitor refuses; in basic mode, they send nothing.
Your Conversions In Three Blocks
Set your mode, your refusal rate and your volumes: the card separates what Google Ads measures, what it can model and what it misses.
The 700-click threshold, the 2 to 5 gap and the 50% example come from Google Ads help on consent mode modeling, read on 15 October 2026. Google adds that the gap varies widely with consent rates, industry and conversion type: the range shows the usual case, and your account can fall outside it.
Google’s Official Thresholds
The same settings, checked against the conditions Google publishes to model what refusals hide from it.
Google Ads: Conversion Modeling
- 700 clicks over 7 days, per country and domain
- The model used
Google Analytics: Behavioral Modeling
- Advanced mode, tags loaded before the banner
- 1,000 users per day who accept, 7 days out of 28
- 1,000 events per day with refusal, for 7 days
Conditions from Google Analytics help on behavioral modeling and Google’s consent mode overview, read on 15 October 2026. The tool assumes steady traffic: Google counts days, and an average can hide days below the threshold.
How The Tool Splits Your Conversions
refusal share = refusals ÷ (refusals + acceptances × k) k = 2 to 5, the gap Google publishes
A visitor who refuses cookies converts less often than one who accepts. Google Ads help on consent mode modeling states that consented users are typically 2 to 5 times more likely to convert, and gives an example: with a 50% consent rate, only 12 conversions out of 62 drop out, or 19%. The tool applies both ends of that gap, hence a range in each block.
These conversions from visitors who refuse form a reserve. Google Ads can model it on two conditions: consent mode correctly implemented, and 700 ad clicks over 7 days for the same country and domain. In advanced mode, tags send cookieless pings and Google builds a model specific to your account. In basic mode, it receives nothing from visitors who refuse and uses a general model, less detailed.
I prefer to stop at the reserve: Google publishes no recovery rate. Its model aims to minimize over-prediction, and the help page notes that some conversions that really happened may not be counted. Your account’s figure lives in Google Ads: consent mode impact results divide modeled conversions by observed conversions, for each country and domain.
The 4 Parameters Of Consent Mode V2
- ad_storage: advertising cookies. According to Google’s documentation, a refusal means no advertising cookie is read or written, and the conversion can no longer be tied directly to the ad click.
- analytics_storage: measurement cookies, such as visit duration. Refused, no Google Analytics cookie; in advanced mode, tags send cookieless measurements for basic measurement and modeling.
- ad_user_data, added in v2: sending the user’s data to Google for advertising. Refused, no user_id and no enhanced conversions.
- ad_personalization, added in v2: personalized advertising. Refused, remarketing and personalized advertising no longer receive their data.
Frequently Asked Questions
What is consent mode v2?
It is the version of Consent Mode that adds ad_user_data and ad_personalization to the two original parameters, ad_storage and analytics_storage. Tag Manager help explains that Google added them to enforce its EU user consent policy: to measure, personalize and remarket with visitors from the European Economic Area, you collect their consent and share it with Google. The same page states that a site already using consent mode without personalized advertising, such as remarketing, has no action to take.
Basic vs advanced consent mode: what is the difference?
In basic mode, Google tags stay blocked until the visitor chooses: if they refuse, nothing is sent, not even their choice, and Google Ads models with a general model. In advanced mode, tags load on arrival and send cookieless pings when the visitor refuses: Google builds a model specific to your account, more detailed. Google Analytics models the behavior of visitors who refuse in advanced mode only. The choice between the two also involves whoever handles your compliance: the tool only shows what it changes for your measurement.
How many conversions does consent mode modeling recover?
Google publishes no general rate. Its help gives a single example with figures: a 50% consent rate, 12 conversions out of 62 lost to measurement, or 19%, and an 18% conversion rate uplift from modeling. For your account, the figure lives in Google Ads: consent mode impact results, in the Diagnostics tab of your conversions, compare modeled conversions with observed conversions, per country and domain. They show as soon as 7 days after implementation if thresholds are met, stay visible for 4 weeks after the modeling start date, and an uplift below 1% does not appear.
How do I check that consent mode works?
Google Ads help gives two ways. On a page of your site, Google Tag Assistant shows whether consent mode is correctly implemented there. In Google Ads, hover over the tracking status of a conversion action: if consent mode is implemented, the card should say “Conversion modeling for consent mode is active”, with a link to the Diagnostics tab.
Is Your Consent Mode Wired Correctly?
Consent mode on every page, the order of its calls and the cookieless pings decide what Google can model. Google Ads help points to these when modeling brings less than expected.
