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.

28 January 20264 min read

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content is published without following SEO best practices, third-party scripts slow things down, dependencies become outdated, and search engine requirements change.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  • Outdated dependencies (npm audit, Dependabot)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

SeverityImpactPriority
CriticalHigh traffic pageFix immediately
CriticalLow traffic pageFix this week
WarningHigh traffic pageFix this sprint
WarningLow traffic pageAdd to backlog
InfoAnyNice 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:

  1. Core Web Vitals failures (direct ranking signal)
  2. Missing or incorrect meta data on high-traffic pages
  3. Broken links and 404 errors
  4. Security issues

Turning Audit Findings into a Roadmap

  1. Export your audit results (CSV or PDF) to share with your team
  2. Categorize issues by area (performance, SEO, accessibility) and severity
  3. Estimate effort for each fix (quick win vs. major refactor)
  4. Assign ownership — who is responsible for each area?
  5. Set deadlines — critical issues in 1 week, warnings in 1 month
  6. 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.
