Optimise SEO

No visual redesigns or layout changes. Allowed: metadata, structured data, semantic HTML, internal links, alt text, sitemap/robots, performance tuning.

Workflow

Inventory routes and index intent
Fix crawl/index foundations
Implement metadata + structured data
Improve semantics, links, and CWV
Validate with seo-checklist.md and document changes

Must-have

Sitemap (
```
app/sitemap.ts
```
) and robots (
```
app/robots.ts
```
)
Canonicals consistent on every page
Unique titles + descriptions
OpenGraph + Twitter Card tags
JSON-LD: Organization, WebSite, BreadcrumbList (+ Article/Product/FAQ as needed)
One h1 and logical heading hierarchy
Alt text, internal links, CWV targets, mobile/desktop parity

Programmatic SEO (pages at scale)

Validate demand for a repeatable pattern before generating pages
Require unique value per page and defensible data
Clean subfolder URLs, hubs/spokes, and breadcrumbs
Index only strong pages; monitor indexation and cannibalization

SEO audit (triage order)

Crawl/index: robots, sitemap, noindex, canonicals, redirects, soft 404s
Technical: HTTPS, CWV, mobile parity
On-page/content: titles/H1, internal links, remove or noindex thin pages

Don't

Over-generate thin pages or doorway pages
Omit or conflict canonicals
Block crawlers unintentionally
Rely on JS-only rendering without SSR/SSG
