Critical Importance

⚠️ NON-NEGOTIABLE: As emphasized by Michael Merlino, UTM tracking is absolutely critical for attribution and ROI measurement. Without proper UTM tags, you're flying blind and cannot prove the value of your SEO efforts.

Why This Matters: UTM parameters are your forensic evidence. They prove which channels drive conversions, justify budgets, and guide optimization decisions. This is the foundation of data-driven SEO.
