How to Do a Website Audit

To do a website audit, systematically review your whole site across every lens that affects its performance: technical health, SEO, content, user experience/design, page speed and Core Web Vitals, conversion, and security — then compile and prioritize the findings into a fix list. A website audit is broader than an SEO audit: the SEO audit is one lens within a full-site checkup that also covers UX, performance, and conversion. Here’s how to run the complete audit.

This guide covers the full website audit — every lens, with SEO as just one of them.

What a website audit is (vs. an SEO audit)

A website audit is a comprehensive review of your site’s health and performance across multiple dimensions — technical, SEO, content, UX/design, speed, conversion, and security. It’s broader than an SEO audit, which focuses specifically on search-ranking factors. Think of the SEO audit as one lens within the website audit. The goal: find everything holding the site back — for users, search, and business results — and prioritize the fixes.

Step 1 — Audit technical health

Check the site’s technical foundation:

• Crawlability/indexing — can search engines access and index the right pages?
• Broken links/404s, redirects (no chains/loops), sitemap/robots.txt.
• HTTPS/security, mobile-friendliness, structured-data errors.

Technical problems can undermine everything else, so check them early.

Step 2 — Audit SEO (one lens of many)

Run the SEO audit lens:

• On-page — titles, headings, keyword targeting, internal linking.
• Content quality/relevance, E-E-A-T, duplicate content.
• Off-page — backlink profile health.

(This is where the full SEO-audit process fits — as part of the website audit.)

Step 3 — Audit content

Review the content itself:

• Quality, accuracy, and helpfulness — thin, outdated, or unhelpful pages?
• Coverage/gaps (content gaps) and cannibalization.
• Freshness — what needs refreshing?

Step 4 — Audit user experience and design

Assess the experience:

• Navigation and site structure — easy to find things?
• Design/usability — clear, professional, accessible?
• Mobile experience — usable on phones.
• Accessibility basics.

Step 5 — Audit performance (speed & Core Web Vitals)

Check how fast and stable the site is:

• Page speed and Core Web Vitals (field data).
• Image/code optimization, server response.
• Performance affects rankings, UX, and conversions.

Step 6 — Audit conversion

Evaluate whether the site turns visitors into customers:

• Clear CTAs and conversion paths.
• Landing/service pages doing their job?
• Friction/leaks in key journeys (forms, checkout).

A site that ranks but doesn’t convert has a conversion problem the audit should surface.

Step 7 — Compile, prioritize, and plan fixes

Turn findings into action:

• Compile all issues across lenses into one list.
• Prioritize by impact and effort — high-impact/low-effort first; fix critical technical/UX issues before polish.
• Assign and schedule the fixes; re-audit periodically (a website audit is maintenance, not one-and-done).

The bottom line

Do a website audit by reviewing the whole site across every lens — technical, SEO, content, UX/design, speed/Core Web Vitals, conversion, and security — then compiling and prioritizing the findings into a fix list. It’s broader than an SEO audit, which is just one lens within it. Prioritize high-impact fixes first, and re-audit periodically. (SEO consulting runs full website audits and fixes what it finds — or run a free site audit.)

Frequently asked questions

How do I do a website audit? Systematically review your whole site across every lens that affects its performance: technical health (crawlability, indexing, broken links, redirects, security, mobile), SEO (on-page, content quality, backlinks), content (quality, gaps, freshness), user experience and design (navigation, usability, mobile, accessibility), performance (page speed and Core Web Vitals), and conversion (CTAs, conversion paths, friction). Compile all findings into one list, prioritize by impact and effort — fixing critical technical and UX issues first — assign and schedule the fixes, and re-audit periodically.

What is a website audit? A website audit is a comprehensive review of a site’s health and performance across multiple dimensions — technical, SEO, content, user experience and design, page speed, conversion, and security. Its goal is to identify everything holding the site back for users, search engines, and business results, and to prioritize the fixes. It’s broader than an SEO audit, which focuses specifically on search-ranking factors; a website audit treats SEO as one lens within a full-site checkup that also covers UX, performance, and conversion.

What’s the difference between a website audit and an SEO audit? A website audit is the broad, full-site checkup covering technical health, SEO, content, user experience, performance, conversion, and security. An SEO audit focuses specifically on the factors that affect search rankings — technical SEO, on-page optimization, content, and backlinks. The SEO audit is essentially one lens within the broader website audit. If you only want to improve search rankings, an SEO audit suffices; if you want a complete picture of the site’s health, including UX and conversion, a full website audit is the wider review.

What should a website audit include? A thorough website audit should include technical health (crawlability, indexing, broken links, redirects, sitemap, robots.txt, HTTPS, mobile-friendliness, structured data), SEO (on-page optimization, content quality, E-E-A-T, backlinks), content (quality, accuracy, gaps, cannibalization, freshness), user experience and design (navigation, usability, accessibility, mobile), performance (page speed and Core Web Vitals), conversion (CTAs, conversion paths, friction), and security. Together these dimensions reveal everything affecting the site’s performance for users, search, and business, producing a prioritized list of fixes.

How long does a website audit take? It varies with the site’s size and the audit’s depth — a small site’s basic audit might take a few hours, while a large site’s comprehensive audit across all lenses can take days. Automated tools speed up parts (technical crawling, performance testing), while manual review of content quality, UX, and conversion takes more time. The key is thoroughness over speed: rushing risks missing issues. Budget enough time to review each lens properly, since a superficial audit that misses important problems provides limited value.

How often should I audit my website? Conduct a comprehensive website audit periodically — commonly one to a few times a year — with more frequent checks for larger or fast-changing sites. Beyond scheduled full audits, monitor key areas continuously: watch Search Console for technical and indexing issues, track Core Web Vitals and performance, and review analytics for conversion problems. Issues accumulate over time as content, code, and the site evolve, so combining periodic full audits with ongoing monitoring keeps the site healthy rather than letting problems build up unnoticed.

Can I do a website audit myself? Yes, you can perform a basic website audit yourself using free tools — Google Search Console for technical and indexing issues, PageSpeed Insights for performance, and manual review of content, navigation, mobile experience, and conversion paths. This covers much of the essential ground. Deeper audits — comprehensive technical crawls, detailed backlink analysis, and expert UX and conversion review — may benefit from professional tools or specialists. But the core website audit across the main lenses is accessible to do yourself with a systematic checklist and the free tools available.
