What we're building
A marketing landing page that hits 100/100 on Lighthouse SEO. Critical because most paid-traffic landing pages bleed conversions when they score < 90.
Checklist:
- Doctype, html lang.
- Title (under 60 chars, keyword first).
- Meta description (155 chars).
- Canonical.
- OG 5-tag set with absolute image URL.
- Twitter card.
- JSON-LD Organization or Product.
- Viewport, charset.
- All images have alt.
- Single h1, descendant headings don't skip.
Lighthouse runs each of these explicitly. Miss any one = no longer 100.
