How to Audit a Website: A Step-by-Step Guide
Everything you need to know about website audits — what to check, how to prioritize issues, and how to turn findings into actionable improvements.
A website audit is a comprehensive analysis of your site's performance, SEO, accessibility, and technical health. Done right, it uncovers the issues holding your site back and gives you a clear roadmap for improvement.
Why You Need Regular Website Audits
Websites degrade over time. New content is published without following SEO best practices, third-party scripts slow things down, dependencies become outdated, and search engine requirements change. An audit every 1-3 months keeps everything in check.
Signs you need an audit now:
- Organic traffic has dropped unexpectedly
- New pages aren't getting indexed
- Your site feels slow compared to competitors
- You've recently migrated to a new platform
- You're preparing for a major redesign
The 5 Areas of a Complete Website Audit
1. Performance Audit
What to check:
- Core Web Vitals (LCP, CLS, INP)
- Time to First Byte (TTFB)
- Total page size and number of requests
- Render-blocking resources
- Image optimization
Key tools: Google PageSpeed Insights, Chrome DevTools Performance tab, Krokanti Audit
What "good" looks like:
- LCP < 2.5 seconds
- CLS < 0.1
- INP < 200ms
- Total page size < 1.5MB
- TTFB < 600ms
2. SEO Audit
What to check:
- Meta titles and descriptions (unique, correct length)
- H1 tags (one per page, contains primary keyword)
- URL structure (descriptive, hyphen-separated, no parameters)
- Canonical tags (no duplicate content)
- robots.txt (not accidentally blocking important pages)
- XML sitemap (up to date, submitted to Search Console)
- Internal linking structure (key pages within 3 clicks)
- Structured data (JSON-LD schemas)
3. Accessibility Audit
What to check:
- Alt text on all meaningful images
- Color contrast ratios (4.5:1 for normal text)
- Form labels and error messages
- Keyboard navigation (can you tab through the entire site?)
- Focus indicators (visible when tabbing)
- Semantic HTML and ARIA usage
Target: WCAG 2.1 Level AA compliance
4. Security & Best Practices
What to check:
- HTTPS (all pages, no mixed content)
- Security headers (CSP, X-Frame-Options, HSTS)
- Outdated dependencies (npm audit, Dependabot)
- No sensitive data exposed in source code or client-side JS
- CORS configuration
5. Content Audit (Manual)
What to check:
- Thin content pages (under 300 words with no clear purpose)
- Duplicate or near-duplicate content
- Outdated or inaccurate information
- Missing or poor-quality meta descriptions
- Internal links to 404 pages
How to Prioritize Issues
Not all issues are equal. Use this framework to prioritize:
Severity × Impact Matrix
| Severity | Impact | Priority |
|---|---|---|
| Critical | High traffic page | Fix immediately |
| Critical | Low traffic page | Fix this week |
| Warning | High traffic page | Fix this sprint |
| Warning | Low traffic page | Add to backlog |
| Info | Any | Nice to have |
The 80/20 Rule
In most sites, 80% of the performance and SEO gains come from fixing 20% of the issues. Focus on:
- Core Web Vitals failures (direct ranking signal)
- Missing or incorrect meta data on high-traffic pages
- Broken links and 404 errors
- Security issues
Turning Audit Findings into a Roadmap
- Export your audit results (CSV or PDF) to share with your team
- Categorize issues by area (performance, SEO, accessibility) and severity
- Estimate effort for each fix (quick win vs. major refactor)
- Assign ownership — who is responsible for each area?
- Set deadlines — critical issues in 1 week, warnings in 1 month
- Schedule follow-up — re-audit in 4 weeks to measure progress
Automated vs. Manual Auditing
Automated tools (like Krokanti Audit) are excellent for:
- Catching technical issues at scale
- Consistent, repeatable checks
- Tracking improvements over time
- Getting specific, actionable recommendations via AI
Manual review is still needed for:
- Content quality assessment
- UX and conversion rate optimization
- Competitive analysis
- Business logic errors
The best approach: automated audit first to get the full picture fast, then manual investigation of the most critical issues.
