fix(seo): trailing slash consistency for hreflang/canonical/sitemap#236
Merged
Conversation
…map URLs Semrush flagged 9 hreflang conflicts because Vercel serves both /en and /en/ as 200 (no redirect), so whichever form tags use conflicts with the alternate crawled URL. Fix: enable trailingSlash: true in Next.js config so Vercel redirects /en → /en/ (308). Update page.tsx and sitemap generator to produce trailing-slash URLs consistently across: - <link rel="canonical"> - <link rel="alternate" hreflang> - sitemap.xml <loc> and <xhtml:link> Build tested locally — static export now generates directory-based index.html files (en/index.html instead of en.html).

Summary
trailingSlash: truein Next.js config — Vercel will 308-redirect/en→/en/page.tsxto produce trailing-slash canonical and hreflang URLs for all pages<loc>and<xhtml:link>URLsRoot cause
Vercel serves both
/enand/en/as HTTP 200 with identical content (no redirect). Semrush discovers URLs from the sitemap (no trailing slash) and from internal links (with trailing slash), treats them as distinct, and flags the mismatch between the crawled URL and canonical/hreflang tags.What changes
