What is included in a professional SEO audit?

A professional SEO audit covers eight core areas: technical SEO (crawlability, indexation, site speed), on-page optimisation (titles, meta descriptions, content structure), content quality (thin content, duplicates, E-E-A-T), backlink health (toxic links, anchor distribution), schema markup validation, Core Web Vitals performance, AI search readiness, and UK-specific compliance (GDPR, cookie consent).

How long does an SEO audit take?

A basic DIY audit using free tools takes two to four hours. A comprehensive professional audit for an SME website takes two to three weeks, including data collection, analysis, and report compilation. Enterprise audits with thousands of pages typically require four to eight weeks.

Can I do an SEO audit myself?

Yes, using this checklist and free tools like Google Search Console, Screaming Frog (free for up to 500 URLs), and PageSpeed Insights. A DIY audit covers the fundamentals well. The advantage of a professional audit is prioritisation.

How often should I audit my website for SEO?

Quarterly for most SMEs, monthly for mid-market businesses with 50 or more target keywords, and weekly automated monitoring for enterprise sites.

What is the difference between an SEO audit and an AI search audit?

A traditional SEO audit focuses on ranking in Google's organic search results. An AI search audit (AEO audit) examines whether your content can be found and cited by AI platforms like Google AI Overviews, ChatGPT, and Perplexity.

What should I do after completing an SEO audit?

Prioritise and implement. Address P0 critical issues within the first week — these capture approximately 70% of available ROI. Follow with P1 high-priority fixes within 30 days, P2 medium-priority within 60 days, and P3 within 90 days.
