Superseded release pages that were taking two brand sitelink slots (5.9k
impressions, 29 clicks). They still render for old links; hreflang is
only emitted for a page that is its own canonical (prerender + useSEO).
- useSEO: for the static SEO routes (marketing pages, examples gallery,
editor, home) the canonical is now the page's OWN locale variant and the
head lists every locale variant as rel=alternate hreflang plus x-default
on the locale-less English URL. /es/ and /zh-cn/ were declaring
canonical=/ while Google indexed and ranked them on their own — an
unstable contradiction. UGC pages (projects, profiles, example detail
pages) are the same English content under every prefix and keep a single
locale-less canonical with no hreflang.
- prerender-seo.mjs emits the same hreflang set into each prerendered page
and writes dist/seo-routes.json (path/title/description) so the prod app
shell can serve the /<locale>/<route> variants (which have no static file)
with the route's own head.
- /editor gets seoMeta and a static SSR summary component, so it is
prerendered: nginx now serves /editor/ as a real page and 301s /editor to
it. Both forms answered 200 with the homepage head before, and Google
indexed /editor and /editor/ as two pages.
Static/docs/example routes are served as <route>/index.html and nginx
301-redirects the slash-less form to add the trailing slash. The sitemap
generator, the prerender canonical/og:url, and the client useSEO canonical
all emitted the slash-LESS form, so every sitemap URL was fetched as a
redirect (filed under 'Page with redirect' in Search Console) and each
canonical pointed at a redirecting URL.
Align all three to the trailing-slash form so sitemap URL == canonical ==
served URL == 200, with no redirect hop.
- generate-sitemap.mjs: append '/' to every <loc> (root stays '/')
- prerender-seo.mjs: withSlash() on canonical + og:url (routes + examples)
- useSEO.ts: withTrailingSlash() on canonical + og:url (covers dynamic
project pages too)
