Measurement
Enhanced conversions
Enhanced conversions send hashed first-party customer data alongside a conversion so it can be matched to an ad interaction when cookie-based measurement fails.

What is enhanced conversions?
Enhanced conversions send hashed first-party customer data alongside a conversion so it can be matched to an ad interaction when cookie-based measurement fails. The data is hashed before transmission.
Why it matters
It recovers a share of conversions lost to browser restrictions and consent rejection, which otherwise look like a performance decline.
How it gets implemented
Implemented by passing hashed email or phone data at conversion, which requires the data to be available at that moment and the privacy basis to be in place.
What people get wrong
It is not a replacement for consent. The lawful basis for sending customer data still has to exist, whatever the hashing does.
It is a small idea with a disproportionate effect on how a site performs.
Where this comes up in the work
It is part of AI Platform Optimization, and more specifically of ChatGPT visibility optimization. Across the rest of the work it shows up in:
- Generative Engine Optimization: it is the reason tracking how often the brand is named across a fixed set of buyer questions is scoped the way it is
- Answer Engine Optimization, because keeping the markup in step with what the page visibly says depends on it
- Technical SEO, in which it is the first thing checked before measuring the site on the phone and connection the customers actually have
- Entity and Semantic SEO, where it decides working out which competitor the market keeps confusing the brand with and why
What to check
Two questions that establish whether this is actually in order on a given site:
- Whether the last audit of it predates the current site
- Whether a new page inherits it automatically or has to be remembered

Common questions
How urgent is enhanced conversions?
Before anything that depends on it, which is the test rather than a general ranking. It recovers a share of conversions lost to browser restrictions and consent rejection, which otherwise look like a performance decline.
How would we know enhanced conversions is a problem?
It recovers a share of conversions lost to browser restrictions and consent rejection, which otherwise look like a performance decline. The evidence is specific to the site, which is why the check comes before the recommendation.
Is enhanced conversions just another name for something?
It is not a replacement for consent. The lawful basis for sending customer data still has to exist, whatever the hashing does. The distinction matters because the two are fixed differently.
Is enhanced conversions a ranking factor?
It recovers a share of conversions lost to browser restrictions and consent rejection, which otherwise look like a performance decline. Whether that becomes a ranking change depends on what else is true about the site, which is why it is worth measuring rather than assuming. Ecommerce and retail is the shortest useful page on this. Education and training is the most complete.
How do you check enhanced conversions on a site?
Implemented by passing hashed email or phone data at conversion, which requires the data to be available at that moment and the privacy basis to be in place. The check is cheap; the fix is where the work sits. Google Ads Management is the prerequisite. Lifecycle and Email is what it makes possible.
Whose job is enhanced conversions?
It needs one named owner rather than a shared responsibility. The natural home is analytics and measurement, since finding the segment where the average is hiding the story is where the consequence lands. GEO or SEO handles the common case; Google Ads or Meta Ads handles the one that catches people out.
Replace the assumptions with measurements
No pitch deck. A short call, a look at the data you already have, and a view on whether this is worth doing at all.
