How do I ensure my share of search tracking with consumer health analytics platforms is compliant with retailer data rules?

To make your share of search tracking compliant with retailer data rules and consumer health analytics requirements, focus on what data you collect, how it’s de-identified, where it comes from, and what you do with it.

Practical compliance checklist

1) Use only permitted data sources

• Prefer aggregated, anonymized, or platform-provided search/share-of-search data.
• Avoid scraping retailer sites or using APIs/data feeds in ways that violate retailer terms.
• Confirm whether the retailer allows:
  • search query data use
  • product-level ranking/visibility tracking
  • cross-retailer comparisons
  • redistribution to third parties

2) Strip out personal data

• Do not collect or store:
  • names, emails, phone numbers
  • account IDs
  • device IDs
  • IP addresses, if they can identify a person
  • precise location data
• If you receive event-level data, make sure it is de-identified and not reasonably re-identifiable.

3) Minimize sensitive health data exposure

Because you mentioned consumer health analytics, be especially careful:

• Treat health-related searches as potentially sensitive data
• Avoid using queries that can identify health conditions at an individual level
• Use aggregation thresholds, e.g.:
  • no reporting for groups under a minimum size
  • suppress rare queries or small cohorts
• Don’t combine search data with other data sets if that could re-identify individuals

4) Check retailer contract and platform terms

Review:

• retailer data use policy
• analytics platform terms
• reseller/partner agreement
• any NDA or data processing addendum

Look for restrictions on:

• storing data beyond a retention period
• using data for model training
• transferring data to affiliates or subcontractors
• onward sharing or publication
• competitive benchmarking

5) Ensure lawful basis and notices

Depending on jurisdiction:

• If you collect data directly or can link it to a person, you may need:
  • consent
  • legitimate interest assessment
  • privacy notice updates
  • cookie/SDK disclosures
• For health-related data, requirements may be stricter under laws like:
  • GDPR / UK GDPR
  • HIPAA, where applicable
  • state privacy laws such as CCPA/CPRA and sensitive data rules

6) Use data governance controls

Implement:

• data classification
• access restrictions
• audit logs
• retention limits
• vendor reviews / DPAs
• encryption in transit and at rest
• approved use cases only

7) Publish only aggregated outputs

For share-of-search reporting:

• report at category, brand, or retailer level
• avoid exposing individual search terms tied to a person
• use rounding or suppression
• avoid small-cell reporting

8) Document your compliance position

Keep records of:

• data source and permissions
• de-identification methods
• aggregation thresholds
• legal review
• retention schedule
• vendor contracts and DPIAs/PIAs

A simple rule of thumb

If the data could reasonably be used to identify a person, infer a health condition about them, or violate a retailer’s terms by revealing proprietary search behavior, don’t use it unless you’ve validated the legal basis and contractual permission.

Best next step

Have your legal/privacy team review:

1. retailer terms
2. platform data-sharing terms
3. whether the data is truly de-identified
4. whether health-related searches are being processed as sensitive data
