Question
A marketing strategist is interested in enhanced conversions for web. What description could their agency provide to explain this feature
A. Enhanced conversions for web uses third party data to unlock more powerful bidding.
B. Enhanced conversions for web uses Google Analytics to unlock more powerful bidding.
C. Enhanced conversions for web uses hashed, first-party data to unlock more powerful bidding.
D. Enhanced conversions for web uses third party data to improve the accuracy of your conversion measurement.
The correct answer
C. Enhanced conversions for web uses hashed, first-party data to unlock more powerful bidding.
Why the correct answer is right
Enhanced conversions for web uses hashed, first party data to unlock more powerful bidding.
- Uses data customers enter on your site, like email, phone, or name from checkout or lead forms. This is first-party data from your own pages, not from outside companies.
- Protects privacy by hashing data. Before any data leaves the page, it is converted into a fixed-length code using SHA-256. This code cannot be reversed to reveal the original details. It is only used to try to match the conversion to a Google account.
- Improves match rate. When matches occur, more conversions are counted even with limited cookies or when people switch devices. A better match rate makes reports more accurate.
- Improves smart bidding. With more confirmed conversions, Google Ads learns faster which clicks lead to sales or leads. Bids adjust in real time to focus budget on the best-performing traffic.
- Works with your current tags. Turn it on in the Google Ads conversion action and map the fields in the Google tag or in Tag Manager. No new platform is needed.
- Respects consent and policy. It can work with consent mode so tags adapt to user choices. You only use data that you collected with permission on your site.
Enhanced conversions for web use the data people already give you, hash it for protection, and use it to recover and improve conversion signals for better bidding.
Why the other options are wrong
- A. Enhanced conversions for web uses third party data to unlock more powerful bidding
- What it gets wrong: Third-party data is information collected by outside companies that don’t have a direct relationship with your customers on your site.
- The truth: Enhanced conversions use first-party data from your own pages. This respects privacy and avoids relying on third-party cookies.
- B. Enhanced conversions for web uses Google Analytics to unlock more powerful bidding
- What it gets wrong: It suggests that Google Analytics powers the feature.
- The truth: Enhanced conversions is a Google Ads feature. You enable it inside the Google Ads conversion action and send hashed data with the Google tag or Tag Manager. Google Analytics 4 can be linked to Google Ads, but GA4 is not required for enhanced conversions to work.
- D. Enhanced conversions for web uses third party data to improve the accuracy of your conversion measurement
- What it gets wrong: It again says third-party data is the source.
- The truth: Accuracy improves because your site’s first-party data is hashed and matched. No third-party data is used.
So the only correct description is the one that mentions hashed first party data as the method and more powerful bidding as the outcome.
