# Cookie-less Alternatives Evaluation Workflows

## Evaluation Workflow

1. Audit current cookie-dependent functionality (analytics, advertising, personalization)
2. For each dependency, identify cookie-less alternative
3. Assess alternative's browser support (Chrome-only vs cross-browser)
4. Evaluate data quality compared to cookie-based approach
5. Determine consent requirements for each alternative
6. Create implementation roadmap prioritizing cross-browser solutions

## Topics API Implementation Workflow

1. Register with Chrome Origin Trial (if still in trial)
2. Add Permissions-Policy header: browsing-topics=(self)
3. Implement fetch calls with {browsingTopics: true}
4. Build topic-to-ad-campaign mapping
5. Test targeting quality compared to cookie-based targeting
6. Monitor opt-out rates and topic coverage

## Attribution Reporting Implementation Workflow

1. Register attribution source on ad clicks/impressions
2. Register attribution triggers on conversions
3. Set up event-level report collection endpoint
4. Set up aggregatable report collection via aggregation service
5. Adapt reporting to work with noisy, delayed data
6. Compare with cookie-based conversion data for validation

## Cookieless Analytics Deployment Workflow

1. Evaluate Plausible, Fathom, or Umami against requirements
2. Choose hosting model (managed SaaS or self-hosted)
3. Deploy tracking script (typically single lightweight script)
4. Verify no cookies or PII collected
5. Confirm with local DPA guidance whether consent required
6. Run in parallel with existing analytics for 30 days to compare
