Enhanced Conversions improve attribution accuracy, but peptide brands need to be more careful than most about what customer data actually gets passed to Google.
Enhanced Conversions close the attribution gap that cookie restrictions and ad blockers have created, by hashing and matching customer data like email or phone at conversion time. For most ecommerce categories, that's a straightforward win. For peptide brands, the setup deserves an extra layer of care, because the same customer data flowing into Google's systems in a sensitive product category raises questions worth answering deliberately rather than defaulting into.
Enhanced Conversions hashes customer-provided data, typically email address, phone number, or name and address, before sending it to Google for match-back against signed-in Google accounts. The raw data itself isn't visible to Google in unhashed form, but the fact that a match occurred, and that it's tied to a conversion event on your site, still means customer purchase behavior in this category is being associated with an identifiable person at the platform level.
| Step | What To Do |
| 1. Update your privacy policy first | Clearly disclose that hashed customer data is shared with advertising platforms for conversion measurement, before implementation, not after |
| 2. Choose the implementation method deliberately | Google Tag-based Enhanced Conversions for leads vs. for web, matched to whether you're optimizing for purchases or lead form fills |
| 3. Test in a staging environment | Confirm hashing is applied correctly before it goes live, unhashed data sent by mistake is a real risk during setup |
| 4. Monitor match rate, not just conversion volume | A sudden match rate spike or drop can indicate a technical issue worth investigating before it affects bidding |
Avoid passing more customer fields than you need for matching. Email alone often provides sufficient match rate improvement without adding phone number or physical address into the mix, which increases the data footprint without a proportional attribution benefit for most peptide ecommerce setups.
Better attribution means your bidding algorithms get cleaner signal, which matters more, not less, in a restricted category where every campaign needs to prove efficiency without being able to rely on broad audience expansion tactics that are off-limits under policy. This is part of the same measurement discipline behind the account structure covered in our multi-compound account structure guide.
We'll implement Enhanced Conversions with a privacy-first setup that improves attribution without overreaching on what data gets shared.
