伺服器端標記同同意
Server-side tagging係GTM 2012以嚟營銷技術入面最大嘅變化。將標籤由瀏覽器搬到伺服器改善數據質素。但危險嘅誤解喺度擴散：標籤喺伺服器度行唔使同意。呢個係錯嘅。
Myth: Server-side tags → no consent needed.
Reality: GDPR regulates data processing, not code location. IP + purchase data = consent required.
- 1. CMP → consent in browser
- 2. Consent state → server container
- 3. Server tags check consent before firing
- 4. Consent Mode V2 respected server-side
- Data quality: 15-25% less ad blocker loss
- Faster pages: Better Core Web Vitals
- First-party context
- Consent Mode V2 compatible
- Skip consent entirely
- Not forwarding consent state
- Firing all tags without checking
- Ignoring TCF for programmatic
