Technical SEO Audit Checklist for Client Websites
Crawlability and indexability
Start by checking whether important pages can be found and crawled. Review internal links, sitemap, robots, HTTPS, canonical signals, and status codes.
If search engines cannot access important pages, content quality will not matter.
On-page fundamentals
Review titles, meta descriptions, headings, content depth, duplicate or missing tags, image alt text, and internal anchor context.
These basics help users and search engines understand the page.
Performance and UX
Check mobile speed, layout shift, large images, unused JavaScript, caching, compression, and render-blocking resources.
Technical SEO is strongest when it improves both crawling and user experience.
