Analytics Tag

One script, your API key — and your storefront starts emitting structured analytics events automatically.

What gets captured

• Pageviews and page-leave timing
• Product impressions, clicks, variant selections
• Add to cart, remove, quantity changes, wishlist
• Search, filter, sort
• Checkout funnel: started, coupon applied, completed
• Order placed, payment initiated / completed / failed
• Form errors and abandonment
• Engagement: scroll depth, time on page, rage clicks, dead clicks
• Web vitals: LCP, INP, CLS, FCP, TTFB
• JavaScript errors and slow API responses
• Feature flags & A/B experiments (variant served + exposure)
• Session replay (DOM playback, PostHog-backed)
• On-page surveys (NPS, ratings, free text)
• Conversion pixels: Microsoft Clarity + Facebook CAPI dedup

All without writing tracker calls — just add data-p-* attributes on the elements you already have.
