Page highlights
Align with hreflang
Canonical URLs should point to the current language version while hreflang alternates connect equivalent localized pages.
Keep sitemap URLs clean
Sitemap entries should use the same canonical pattern that appears in static HTML and SEO metadata.
FAQ
Should the canonical point to English for every page?
No. Localized Chinese pages should normally self-canonicalize and use hreflang to point to English alternates.
Should query parameters be canonicalized?
Most tracking and filter parameters should canonicalize to a clean URL unless they represent unique indexable content.
Do trailing slashes matter?
Yes. Pick one production convention and keep route, canonical, sitemap, and internal links aligned.
