Technical SEO is the foundation everything else sits on. If search engines and AI tools cannot crawl, understand, and trust your site, no amount of content will save it. Use this checklist to find the issues holding you back.
What is a technical SEO audit?
A technical SEO audit reviews the infrastructure of your website: how fast it loads, how well it works on mobile, whether it can be crawled and indexed, and whether its signals are clean. It is the health check before you invest in content.
Crawlability and indexing
- Confirm you have a valid robots.txt that does not block important pages
- Submit an accurate XML sitemap to Google Search Console
- Check that key pages are indexed and not accidentally set to noindex
- Set canonical tags to avoid duplicate-content confusion
Site speed
- Aim for pages that load in under three seconds
- Compress and properly size images
- Defer non-critical scripts so they do not block rendering
- Use caching and a content delivery network
Mobile-friendliness
- Confirm a responsive layout that works on all screen sizes
- Set a proper viewport
- Make tap targets and fonts comfortably usable on phones
Security and structure
- Serve every page over HTTPS with no mixed-content warnings
- Keep a logical, shallow URL structure with readable URLs
- Fix broken links and redirect chains
- Maintain a clear internal linking structure so no page is orphaned
Structured data
- Add Organization, Article, and FAQ schema where relevant
- Validate it with Google's Rich Results Test
How often should you audit?
Run a full audit at least twice a year, and a quick check after any major site change. Small issues compound quietly, so regular reviews protect your rankings and your AI visibility.
