Why run a technical SEO audit?

Find the technical issues that silently kill your search rankings.

🗺️

Check sitemap health

Verify your sitemap is found, valid, and contains all important URLs. A broken sitemap means Google can't efficiently discover your pages.

📡

Audit response codes

Find 404 errors, redirect chains, and server errors in your sitemap URLs. Broken pages waste crawl budget and hurt user experience.

🏷️

Analyze on-page SEO

Check title tags, meta descriptions, H1s, canonical tags, and structured data. Missing or duplicate tags directly reduce your rankings.

⚡

Measure Core Web Vitals

Test LCP, CLS, and other performance metrics via PageSpeed Insights. Slow sites lose rankings and conversions.

🤖

Check AI accessibility

See if AI search engines (ChatGPT, Perplexity, Claude) can access your content. GEO readiness is the next frontier of SEO.

🎯
