- Technical SEO removes access, rendering and interpretation blockers.
- AI visibility still depends on many traditional SEO foundations.
- Fix crawl, indexability and canonical issues before smaller enhancements.
Crawlability and status codes
Important pages should return successful HTTP status codes, serve useful HTML and avoid unnecessary redirects. Broken pages, soft 404s and blocked assets can reduce crawler confidence.
Indexability signals
Review robots meta tags, X-Robots-Tag headers, canonical tags and robots.txt rules so important pages are not accidentally noindexed, canonicalized away or blocked.
Metadata and headings
Every important page should have a descriptive title, useful meta description, one primary H1 and a logical heading structure that helps users and machines understand the page.
Discovery and structure
Use sitemap.xml, internal links, breadcrumbs and clean URL patterns. For single-language sites, keep canonical URLs and sitemap entries aligned.
Performance and HTML hygiene
Fast, lightweight and well-structured pages are easier to fetch and process. Use compression, keep HTML lean, avoid unnecessary scripts and fix malformed markup where possible.
Practical checklist
- Confirm important pages return 200 status.
- Remove accidental noindex and blocking rules.
- Use one canonical URL format consistently.
- Add title, meta description and clear H1.
- Publish sitemap.xml and reference it in robots.txt.
- Add relevant JSON-LD structured data.
- Check mobile rendering and viewport setup.
- Monitor page size, compression and response headers.
Implementation order
- Check status codes, redirects, canonical and robots signals.
- Review title, description, H1 and content structure page by page.
- Fix sitemap, hreflang and structured data issues.
- Repeat performance and HTML hygiene checks regularly.
Frequently asked questions
What should be checked first in technical SEO?

Check after major website changes and regularly over time, especially after new pages, URL versions, redirects or template changes.
