Updated on 9 November 2026 by Nicolas Finet, CEO of Sortlist. This guide has been rewritten with 2026 UK prices: it explains what an SEO audit is, the main types, what drives the cost (from £295 reports to £15,000+ enterprise audits), what you should receive and how to judge whether the price is fair.
An SEO audit reviews your website's technical health, content, links and search performance, and produces a prioritised list of improvements. The price depends mostly on site size and depth. This guide shows what UK businesses typically pay and what to expect for the money.
Key takeaways
- UK SEO audits cost about £500-£15,000+ in 2026: small sites under 100 pages about £500-£2,500, medium sites £2,500-£5,000 and enterprise sites with 500+ pages £5,000-£15,000+.
- Most small and medium businesses pay £1,500-£3,000 for a full technical, content and backlink audit; basic single-scope checks start around £400-£800.
- A good audit is prioritised and actionable: it ranks issues by impact and effort, not just a list of tool warnings.
What is an SEO audit?
An SEO audit is a structured review of how well your website is set up to be found and chosen in search results. It examines how search engines crawl and index the site, how pages perform, whether content matches search intent and how your site compares with competitors. The output should be a report with findings, priorities and recommended actions, often with a roadmap.

Types of SEO audit
Technical audit
Crawlability, indexation, site structure, redirects, canonical tags, XML sitemap, robots directives, page speed, Core Web Vitals, mobile usability, security, structured data and JavaScript rendering.
On-page and content audit
Titles, headings, keyword targeting and intent, content quality and depth, duplication, thin pages, internal linking and opportunities to merge, update or prune. See on-page SEO.
Competitive audit
Compares your visibility, content and links with competitors to find gaps and opportunities.
Link audit
Reviews backlinks for quality and risk, and identifies opportunities. Disavowing links is rarely needed unless there is a manual action or a clear paid-link problem. See how to get quality backlinks.
Local SEO audit
Checks Google Business Profile, citations, reviews and local pages.
Social and brand audit
Reviews social profiles and brand mentions that support search visibility.
AI search visibility audit
A newer option: checks how your brand and content appear in AI-generated answers. This is still developing, so treat claims with caution.
What affects the price?
- Site size: number of pages, templates and languages.
- Complexity: ecommerce, JavaScript frameworks, multiple domains, international setups.
- Scope: technical only or full audit with content and links.
- Depth of analysis: log files, manual review, competitor research.
- Deliverables: a spreadsheet of issues versus a prioritised roadmap, video walkthrough or implementation support.
- Provider: freelancer, specialist agency or large agency.
- Tools: licences for crawlers and data tools.
What should you receive?
- A clear summary of the main findings and their business impact.
- Prioritised issues with severity, effort and expected benefit.
- Specific recommendations, with examples and URLs, not generic advice.
- A roadmap (for example 30-60-90 days) with owners.
- Baseline metrics: traffic, rankings, conversions and Core Web Vitals.
- A debrief call to explain and answer questions.
Be sceptical of audits that are only automated tool exports, include dozens of low-value warnings or promise guaranteed ranking improvements.
Audit alone or ongoing SEO?
An audit finds problems; it does not fix them. You or your developers will need to implement the changes, or you may hire the auditor or another agency to do so. UK SEO retainers typically run about £1,500-£5,000 a month for growing businesses, per 2026 guides. See advanced SEO services.
How to choose an auditor
- Ask for a sample report with sensitive details removed.
- Check experience with sites like yours (ecommerce, local, B2B, international).
- Confirm what is included, the timeline and whether implementation support is available.
- Ask who does the work, and how they prioritise.
- Check references and results, not only certifications.
- Insist on access to the underlying data.
See how to hire an agency and our Google SEO guide.
Can I do my own audit?
Yes, for a small site. Use Google Search Console and PageSpeed Insights (both free), a crawler such as Screaming Frog (with a free version for small crawls), and the checklists in our guides. For larger or complex sites, expert help usually pays for itself.
