Metadata, canonical URLs, sitemaps, structured data, Core Web Vitals, and internal linking — the basics that support good content.

Content earns attention. Technical SEO makes sure search engines can read, index, and trust what you published.
For a Next.js site, check the fundamentals: unique titles and descriptions per page, one clear H1, logical heading hierarchy, and canonical URLs where duplicates could exist. Generate a sitemap and robots.txt. Add structured data where it fits — Person, WebSite, FAQPage, and Service schemas for a developer portfolio.
Performance is part of SEO. Optimize images, avoid unnecessary client JavaScript on content pages, and test on mobile networks. Internal links should use descriptive anchor text — "mobile app development" beats "click here."
Review Search Console after launch. Fix crawl errors early. SEO is iterative; the checklist gets you live responsibly, then content and links do the long-term work.
