A Practical Technical SEO Checklist for Growing Websites

1. Crawlability & indexation

• Confirm important pages return HTTP 200 and are not blocked by robots.txt or noindex.
• Maintain a clean XML sitemap and submit it in Search Console.
• Fix redirect chains and orphaned pages.

2. Performance & Core Web Vitals

• Measure LCP, INP, and CLS with real-user data, not just lab tests.
• Optimize images, defer non-critical JavaScript, and use modern caching.

3. Architecture & internal linking

• Keep important pages within three clicks of the homepage.
• Use descriptive anchor text; avoid orphaning new content.

4. Structured data

• Add Organization, Service, FAQ, and Article schema where eligible.
• Validate with Google's Rich Results Test.

5. Hygiene

• One H1 per page, descriptive titles under ~60 characters, meta descriptions under ~160.
• Canonical tags on parameterized or duplicated URLs.
