Technical quality impacts revenue

A slow page and broken tracking make decisions blind. This checklist is our baseline before launch.

1) Performance & Core Web Vitals

  • LCP: optimize hero media, use WebP/AVIF, correct sizes.
  • CLS: reserve space for images/banners/widgets.
  • INP: keep third‑party scripts under control.

2) SEO basics

  • Unique title/description and one H1.
  • Open Graph/Twitter cards.
  • Canonical to avoid UTM duplicates.

3) Analytics & events

  • CTA clicks, form submit success/fail, key scroll depth.
  • Ads conversions (if you run Google/Meta).

4) Forms reliability

  • Client + server validation.
  • Anti‑spam (honeypot or CAPTCHA when needed).
  • Clear success/error states and retry strategy.

Summary

Treat a landing page like a product: measure, optimize, and keep the pipeline reliable.
