SEO Audit UK: The 2026 Checklist (and What a Free Audit Should Include)

By Netbeam · Updated 2026-11-11

Updated 11 November 2026.

If your website is not bringing in enquiries, an SEO audit is the fastest way to find out why. It shows what is stopping Google from finding, understanding and trusting your pages, and what to fix first.

This guide gives you a practical SEO audit UK checklist you can run yourself, explains what a proper free SEO audit should include, and shows when it is worth asking an expert to do it for you.

What is an SEO audit?

An SEO audit is a structured health check of your website. It reviews your technical setup, on-page content, local signals, authority and, increasingly, how visible you are in AI search tools such as Google AI Mode and ChatGPT. The result should be a short, prioritised list of fixes, not a 90-page report nobody reads.

Why run an SEO audit now?

• Indexing problems are common. Search Engine Roundtable reported in early November that Google updated its documentation on “Crawled – currently not indexed”, a status that leaves many small business pages invisible.
• Search is changing fast. AI answers now sit between the search and your website, so clear, trustworthy pages matter more. See our guide to Google AI Mode in the UK.
• Small fixes compound. Faster pages, better titles and cleaner internal links often lift rankings without writing a single new page.
• Year-end is the time to plan. An audit in November gives you a clear roadmap for the new year.

The 15-point SEO audit UK checklist

Work through these in order. The first block matters most, because nothing else works if Google cannot crawl and index your site.

Technical SEO audit (points 1 to 6)

1. Indexing: open the Pages report in Google Search Console and check how many pages are indexed, and why others are not.
2. XML sitemap and robots.txt: make sure your sitemap is submitted and that robots.txt is not blocking important pages.
3. HTTPS and redirects: every URL should load securely, with one clean redirect path from old URLs.
4. Page speed and Core Web Vitals: test your key pages in PageSpeed Insights, especially on mobile.
5. Mobile usability: check that buttons, forms and phone numbers work well on a small screen.
6. Broken links and errors: find 404 pages and fix or redirect them. Our technical SEO checklist goes deeper.

On-page and content audit (points 7 to 11)

1. Title tags and meta descriptions: each page needs a unique title with its main keyword and a description that earns the click.
2. Headings and structure: one clear H1, then logical H2 and H3 headings that answer real questions.
3. Content quality: remove or merge thin, duplicate and outdated pages, and avoid keyword cannibalisation where two pages compete for the same search.
4. Internal links: link important pages from your navigation and from related articles, using descriptive anchor text.
5. Schema markup: add structured data such as LocalBusiness, Organization and FAQ where it matches what is visible on the page.

Local, authority and AI visibility (points 12 to 15)

1. Google Business Profile and NAP: check your profile, categories, reviews and that your name, address and phone number match everywhere. See our local SEO guide and local SEO checklist.
2. Backlinks and mentions: review who links to you and remove or disavow only clearly harmful links.
3. Keyword targeting: confirm each key service has a page aimed at a real search term. Our guide to finding keywords for your website shows how.
4. AI search visibility: ask AI tools the questions your customers ask and note whether your business is mentioned. Read how to get found in ChatGPT for the method.

A quick 10-minute self-check

Short on time? These five checks reveal most big problems:

1. Search for your business name in Google. If you do not appear first, you have a visibility or indexing problem.
2. Open Search Console and look at the number of indexed pages versus the pages you expect.
3. Run your homepage through PageSpeed Insights and note the mobile score.
4. Open your site on your phone and try to call, book or fill in a form.
5. Ask an AI tool for the best provider of your service in your town and see who it names.

Typical problems an SEO audit finds

Problem	Why it hurts	Typical fix
Pages not indexed	Google cannot show pages it has not stored	Fix crawl blocks, improve content and add internal links
Slow mobile pages	Visitors leave before the page loads	Compress images, reduce scripts, improve hosting
Duplicate title tags	Pages compete and click-through falls	Write unique titles and descriptions per page
Thin or copied location pages	Little local value for Google or customers	Add genuine local detail, reviews and FAQs
Missing schema	Search engines understand you less clearly	Add accurate structured data that matches the page
No clear call to action	Visitors read but do not enquire	Add clear buttons, forms and phone links

What should a free SEO audit include?

A good free audit is a genuine health check, not just a sales hook. At a minimum it should cover:

• Indexing, crawlability and site speed
• Mobile experience and Core Web Vitals
• On-page issues across your main pages
• Local signals and Google Business Profile basics
• AI search visibility
• A prioritised, plain-English action list with no jargon

Netbeam’s free website audit reviews your SEO health, speed, mobile experience and AI visibility, then gives you a roadmap built around UK keywords and the questions your customers ask. The typical turnaround is one to two working days, and we agree priorities with you before any larger project.

DIY audit or expert audit?

• DIY works for small sites and basic checks like those above.
• An expert audit is better when you have lost rankings, run an online shop, use several locations, or have hundreds of pages.
• Either way, the value comes from fixing the issues, not from the report itself.

After the audit: what happens next?

1. Fix critical technical issues first, such as indexing and speed.
2. Improve key service pages, titles and internal links through our SEO services.
3. Strengthen local and AI visibility with local SEO, AI SEO and GEO services.
4. Re-check results monthly and keep a simple list of what changed.
