Agency sites on Next.js App Router can outperform WordPress on speed and crawlability — if SEO is engineered in, not bolted on.
Metadata and canonicals
Centralize buildMetadata() for titles, descriptions, Open Graph, Twitter cards, and canonical URLs. Every indexable route should override defaults.
Structured data
Ship Organization, WebSite, Service, FAQPage, Article, and BreadcrumbList JSON-LD. Matrix service pages deserve Service schema with areaServed.
Rendering strategy
Use static generation for stable pages and ISR for CMS content. On publish, call revalidatePath and optionally IndexNow for faster discovery.
Performance
Optimize LCP with next/image, font loading, and minimal client JS on landing pages. Core Web Vitals still correlate with rankings and conversion.
