SEO audit pricing varies more than almost any other digital marketing service. You can get an automated report for free. You can also pay an agency $10,000 for a technical analysis of a large e-commerce site. Both are called SEO audits. They are not the same thing.
Here is what the pricing actually reflects, and how to figure out what level of audit your situation needs.
The Price Ranges (and What Each Actually Covers)
Free to £100 — Automated Reports
Tools like Screaming Frog, SEMrush, Ahrefs, and Moz all offer audit-style reports. You enter a URL, the tool crawls your site, and it spits out a list of issues. These are useful for a quick technical snapshot, but they do not tell you which issues actually matter for your specific situation, why your rankings are where they are, or what to fix first.
Automated reports are a starting point, not an analysis. Do not make major decisions based purely on an automated score.
£500 to £1,500 — Small Business or Freelancer Audits
At this range, you are typically paying a freelance SEO consultant or a small agency to do a manual review of your site alongside the automated data. A good audit in this bracket covers:
- Technical issues — crawlability, indexation, page speed, mobile usability
- On-page factors — title tags, meta descriptions, heading structure, content gaps
- Backlink profile overview
- Basic keyword positioning and competitor comparison
- A prioritised list of recommendations
For most small to medium websites, this is where the useful analysis actually happens. The deliverable is usually a report plus a consultation call to walk through findings.
£2,000 to £5,000 — Mid-Level Agency Audits
At this level, you are getting a more thorough technical crawl, a content gap analysis, a detailed backlink audit with toxic link assessment, and usually a competitive landscape review. These audits are appropriate for sites with several hundred pages, e-commerce catalogues, or businesses in competitive markets where SEO drives meaningful revenue.
The extra cost goes toward analyst time — more pages reviewed manually, deeper investigation of crawl issues, and more specific recommendations tied to your business goals rather than generic best practices.
£5,000 to £15,000+ — Enterprise Audits
Large sites, multiple subdomains, international SEO, complex JavaScript rendering issues, or significant technical debt built up over years — these require more time and specialist expertise. Enterprise audits often involve multiple specialists (technical SEO, content, links) and can take four to eight weeks to complete properly.

Red Flags in SEO Audit Pricing
A few things should make you sceptical:
- Very cheap audits from agencies pitching ongoing retainers — the audit is often a loss-leader designed to generate a long list of problems they will then offer to fix. Not always bad, but understand the motivation.
- No call or meeting included — a written report without any conversation about your specific situation is missing half the value. The findings need context.
- Guaranteed rankings mentioned in the same conversation as the audit — an audit is a diagnostic. Ranking guarantees are a separate (and questionable) claim.
- Turnaround under 48 hours for a site with hundreds of pages — proper manual review takes time. A very fast turnaround usually means it is mostly automated.
What to Ask Before Commissioning an Audit
- What tools do you use, and how much of the analysis is manual versus automated?
- Will you give me a prioritised list of recommendations, or just a list of issues?
- Does this include a call to walk through the findings?
- How many pages does this cover, and is there a limit?
- What deliverable format do I get — document, spreadsheet, presentation?
The answers tell you fairly quickly whether you are getting analysis or a report. Those are different products at different prices, and knowing which one you need saves money and frustration.
