Search engines still reward boring technical hygiene. App Router makes the right things easier—central metadata, file-based sitemap and robots—but only if you wire them consistently across routes. This checklist reflects how we keep a multi-page agency site indexable on a single Vercel project ( enzora.vercel.app ), without buying SEO plugins or duplicate WordPress stacks.

1. One canonical host

Pick one HTTPS origin and use it everywhere: metadataBase , canonical tags, JSON-LD url fields, and sitemap.xml locs. We read NEXT_PUBLIC_SITE_URL with a default of https://enzora.vercel.app so previews can override without forked code.

Helper:

export const siteUrl = ( process . env . NEXT_PUBLIC_SITE_URL ?? " https://enzora.vercel.app " ). replace ( / \/ $/ , "" );
