The Complete Website Audit Checklist
Use this checklist to review a website’s health across the four areas that matter most for visitors and search engines: performance, SEO, mobile/UX and security. It’s the same structure we use in our professional audits.
Key takeaways
- Audit four areas: performance, SEO, mobile/UX and security.
- Prioritise fixes by impact, not by how easy they are.
- Re-audit after major changes and at least twice a year.
Performance
- Core Web Vitals (LCP, INP, CLS)
- Image optimisation and modern formats
- Caching and compression
- Server response time (TTFB)
SEO
- Unique titles and meta descriptions
- Crawlability and indexing (Search Console)
- XML sitemap and robots.txt
- Structured data (schema)
- Internal linking and site structure
Mobile & UX
- Mobile-friendly, responsive layout
- Readable text and large enough tap targets
- Clear navigation and obvious calls to action
- No intrusive pop-ups blocking content
Security
- HTTPS and security headers
- Software, themes and plugins up to date
- No known malware or vulnerabilities
- Backups in place and tested
How to prioritise fixes
Rank issues by impact versus effort. A slow-loading homepage or a non-indexable key page beats a dozen minor cosmetic tweaks. Fix the things that affect rankings, conversions and security first.
