H1 & heading structure — exactly one clear topic per page.
Indexability — whether a stray noindex is hiding you from Google.
Mobile viewport — required for mobile-first indexing.
Canonical, Open Graph & structured data — duplicate-content safety and rich results.
Content depth, image alt text, HTTPS & page weight — quality and Core Web Vitals signals.
