# Next.js for SEO and Core Web Vitals: A Technical Checklist

Next.js SEO starts with HTML, routing, metadata, and measurable performance. A Next.js agency should show a checklist, not promise rankings.

## Summary

Ensure primary content is crawlable, metadata is consistent, canonical URLs are correct, and Core Web Vitals are monitored on real pages. Google Search Central and web.dev provide the primary guidance.

## Background

JavaScript can create rich experiences, but crawlers still need discoverable content and links. Web Vitals connect performance to user experience. One lab score cannot replace field data.

## Approach

Review title, description, headings, canonical, sitemap, robots, internal links, and structured data. Test routes with JavaScript enabled and inspect rendered HTML. Measure LCP, INP, and CLS on important templates. Optimize images, fonts, bundles, and third-party requests based on evidence.

Do not promise Google positions. Ask the agency to explain measurement methods, baselines, and interpretation limits. Link this pillar to rendering, architecture, security, and maintenance articles.

## Implications

A strong Next.js agency in Indonesia connects technical SEO to user needs. Performance must be protected from design through deployment, not repaired after traffic arrives.
