Attribution in a post-cookie world

- Optimizing clicks instead of revenue
- No CRO on landing pages
- Ignoring email as a channel
- Vanity metrics (impressions, clicks)
- No attribution discipline
Key takeaways

- SEO compounds; PPC amplifies; CRO converts; email retains
- Track blended CAC + LTV as your North Stars
- Server-side tracking is required
