- SEO checks: metadata, titles, descriptions, landmark usage, canonical URLs, and internal linking practices.
- Performance checks: proper image handling (next/image), lazy loading, and avoidance of render-blocking resources.
- Core Web Vitals monitoring: assess LCP, CLS, and INP implications of changes.
- Mobile & Social: viewport setup, touch target sizes, and social/meta tags validation.
