A frank guide to what a proper SEO audit really costs, what pushes the price up or down, and how to tell a genuine diagnostic from a templated report.
Quick answer: A professional SEO audit in the UK typically costs between £400 and £10,000+ in 2026. Most small and medium-sized businesses pay £1,500 to £3,000 for a full technical, content and backlink audit. Basic single-scope checks start around £400 to £800. E-commerce and larger platforms typically run £3,000 to £8,000. Enterprise audits with revenue modelling and multi-market scope start at £8,000 and can exceed £15,000 for very large sites. Freelancers charge £35 to £150+ per hour depending on seniority; agencies typically charge £75 to £300 per hour. At MJ Web Studio, audits start at £1,500 for small business sites, £3,000 for e-commerce and larger platforms, and £8,000+ for enterprise engagements.
SEO audit pricing in the UK varies more than almost any other SEO service, from £0 automated tool reports to £20,000+ enterprise engagements. The gap exists because "SEO audit" describes wildly different products: a 15-minute automated crawl, a templated PDF resold to every client, or a genuine multi-day investigation carried out by a senior specialist who manually reviews technical health, content quality and link profile.
What actually drives the price is not the label on the service, but three variables: how many pages and how complex the site is, how many of technical, content and backlink analysis are covered, and how much of the work is manual review versus automated software output. A £300 audit and a £3,000 audit can both be marketed as "comprehensive", but only one of them typically involves a specialist manually checking your site rather than exporting a tool report.
This guide breaks down real UK market pricing by site size, audit type and provider, including where MJ Web Studio sits and what our own pricing does and does not cover. If you are deciding between an audit and an ongoing SEO programme, or wondering whether a quote you have received is fair, the sections below should give you a clear answer.
The six bands that cover the market, from automated reports to enterprise engagements. Full breakdowns below.
| Audit budget | Tier | Typical scope | Honest verdict |
|---|---|---|---|
| Under £300 | Automated only | Software crawl, no human review | Not a real audit |
| £300 to £800 | Basic / single-scope | Technical OR on-page only | Fine for a quick check |
| £800 to £1,500 | Small business | Full technical + on-page, under ~50 pages | Right for very small sites |
| £1,500 to £3,000 | Comprehensive SME | Technical + content + backlink + competitors | Right for most established SMBs |
| £3,000 to £8,000 | E-commerce / larger sites | Deeper technical, product data, UX, migration checks | Needed for larger, complex platforms |
| £8,000 and above | Enterprise | Multi-market, revenue modelling, dedicated team | Enterprise and multi-market only |
Senior UK SEO specialist rates currently run at £80 to £175+ per hour. Site sizes are indicative: a 40-page site with a badly broken technical foundation can cost more to audit properly than a clean 150-page site.
Automated crawl report only
None
Generic, templated
Rarely present
Tools like Screaming Frog, Ahrefs Site Audit or Semrush can generate a technical crawl report in minutes for free or for the cost of a monthly tool subscription (£99 to £300). What they cannot do is judge content quality, assess whether your backlink profile is helping or hurting you, understand your competitive position, or prioritise which of the 200 issues flagged actually matter for your specific site.
Below £300, what is sold as an "audit" is almost always this automated output, sometimes with a generic introduction and conclusion added around it. That is a legitimate starting point for a business with no SEO history, but it is not a diagnostic tool a business should use to make investment decisions.
The right use for a sub-£300 report is as a free lead-generation tool from an agency, not as a paid deliverable. If you are being charged for this level of output, you are paying for something you could generate yourself with a free trial of any major SEO tool.
Manual review of one area
Junior to mid-level specialist
Focused, narrow
Partial
At £300 to £800, a genuine person reviews your site rather than only running software, but the scope is narrow. Expect a focused look at one area, usually technical SEO (crawlability, indexing, page speed, mobile usability) or on-page content, rather than a full technical-plus-content-plus-backlink review.
This band suits a small brochure site (under 30 pages) with a specific, known concern: a business that has just noticed a traffic drop and wants a technical diagnosis, or a site owner who wants a one-off content check before a redesign. It is not enough scope for a business trying to understand its full competitive SEO position.
Junior freelancers (£35 to £50 an hour) typically deliver work in this band. Quality varies significantly by individual, so ask to see a sample report before committing. A rushed checklist and a genuinely prioritised action plan can look similar on a price list but are very different in practice.
Full technical + on-page, small sites
Mid-level specialist
Structured, prioritised
Basic roadmap included
£800 to £1,500 is typically the entry point for what most SEO professionals would call a proper full audit: technical health, on-page and content quality, and a basic backlink review, combined into one prioritised report. For a small business site under roughly 50 pages, this is realistic scope for a mid-level specialist working 8 to 15 hours on your account.
This budget makes sense for small businesses, local service providers, and early-stage sites that have never had a professional SEO review. It gives you a genuine baseline: what's broken, what's missing, and what to fix first.
It becomes too tight for sites over roughly 50 to 75 pages, e-commerce stores with product variants, or any business that wants competitor benchmarking included, since that adds meaningful research time this budget does not really allow for.
Technical + content + backlinks + competitors
Senior specialist
Comprehensive, prioritised roadmap
Full 90-day action plan
This is where a comprehensive audit becomes possible for an established small or medium-sized business: full technical health, content and keyword gap analysis, backlink profile review, and a benchmark against two or three direct competitors, delivered as a single prioritised roadmap. At MJ Web Studio, this is our starting price for small business sites, reflecting roughly 15 to 25 hours of senior specialist time.
For a site with 50 to a few hundred pages and a defined market, this budget buys genuine strategic value: not just a list of problems, but a ranked plan showing which three or four fixes will move the needle first. That is the difference between an audit that sits in a drawer and one that actually changes what you do next.
What to expect at this level: a named senior consultant, not a junior analyst, a live walkthrough call to explain the findings rather than just a PDF drop, and priorities tied to business impact rather than a raw list of every technical issue the crawler found, no matter how minor.
Deep technical + UX + migration readiness
Senior specialist or small team
Extensive, segmented by category
Full roadmap + competitor deep-dive
E-commerce platforms and larger content sites (roughly 500 to several thousand pages) take genuinely longer to audit properly: product data and structured markup need checking at scale, faceted navigation and pagination create technical complexity flat brochure sites do not have, and content review has to sample across categories rather than reading every page. This is MJ Web Studio's tier for e-commerce and larger platforms.
At this level you should expect a segmented report, technical, content, UX and backlinks assessed separately with their own prioritised actions, plus deeper competitor analysis covering three to five competitors rather than two or three, and specific attention to any planned migration, replatforming or major redesign, since audit findings change significantly once those are factored in.
This budget is also where revenue exposure modelling starts to make sense: connecting specific technical or content issues to estimated traffic or revenue impact, so the business can prioritise fixes by commercial value rather than by issue count alone.
Multi-market, revenue modelling
Dedicated senior team
Executive + technical dual reporting
90-day roadmap + quarterly strategy
Enterprise audits are justified for multi-national sites running several languages or regions, platforms with 10,000 or more indexed URLs, or businesses where organic search is a primary revenue channel and a technical or content problem could be costing genuine money every month. At MJ Web Studio this tier starts at £8,000, and for very large enterprise platforms, 10,000+ URLs across multiple markets, total cost can extend beyond £15,000 to £20,000.
At this level, the audit should function closer to a strategic consulting engagement than a checklist: a dedicated senior team, executive-level reporting that ties findings to revenue exposure, hreflang and international SEO review where relevant, and direct involvement from stakeholders across product, engineering and content, since enterprise SEO issues are rarely fixable by the marketing team alone.
The same caution applies here as with ongoing SEO retainers: not every large business needs the top of this range. A single-market site with a clean domain and a well-defined page count does not need an enterprise-scoped audit just because the business itself is large. The right question is always the complexity of the site, not the size of the company.
Not every business needs a full audit. Many providers price by audit type rather than by site size, letting you pay for the specific area you are concerned about.
| Audit type | Typical UK cost | What it checks |
|---|---|---|
| Technical SEO audit | £300–£1,500 | Crawlability, indexation, Core Web Vitals, site architecture, structured data |
| On-page / content audit | £300–£1,500 | Keyword targeting, title tags and metadata, content quality and gaps, internal linking |
| Backlink / off-page audit | £400–£1,500 | Link profile quality, toxic or spammy links, anchor text distribution, competitor link gaps |
| Local SEO audit | £400–£1,500 | Google Business Profile, NAP consistency, citations, local pack visibility |
| E-commerce audit | £800–£3,000 | Product schema, category structure, faceted navigation, duplicate content at scale |
| Full / comprehensive audit | £1,500–£8,000+ | All of the above combined into a single prioritised report |
A single-scope audit is the right call when you already know roughly where the problem is: a recent traffic drop that looks technical, or a content refresh before a rebrand. A full audit is the right call when you have never had one, when multiple areas could be contributing to underperformance, or when you are about to commit budget to an ongoing SEO programme and want an accurate baseline first.
Freelancers typically charge £35 to £150+ per hour, agencies £75 to £300+ per hour, and in-house hires £35,000 to £70,000+ a year in salary alone. The right choice depends on budget, site complexity, and whether the audit is a one-off diagnostic or the start of an ongoing relationship.
| Provider | Rate | Best for |
|---|---|---|
| Junior freelancer (0–2 yrs) | £35–£50/hr | Small sites, single-scope checks, tight budgets |
| Mid-level freelancer (2–5 yrs) | £50–£80/hr | SME comprehensive audits, independent consultants |
| Senior freelancer (5–10 yrs) | £80–£110/hr | Complex sites, strategic recommendations |
| Director / strategist (10+ yrs) | £110–£150+/hr | Enterprise, high-competition sites |
| Small specialist agency | £75–£150/hr equiv. | SME comprehensive audits with team backup |
| Large / enterprise agency | £150–£300+/hr equiv. | Enterprise, multi-market, dedicated teams |
Agencies bring broader tool access (enterprise-tier Ahrefs, Semrush or Screaming Frog licences), a second reviewer to sense-check findings, and continuity if a specific person leaves. Freelancers are typically more cost-effective for a single, well-defined audit and can offer more direct access to the person actually doing the work. For most small businesses buying a one-off audit, a senior freelancer or a small specialist agency delivers the best value; for enterprise engagements with multiple stakeholders, an agency's team capacity generally justifies the higher rate.
Six factors explain almost all of the price variation between a £400 quote and an £8,000 quote for what is nominally the same service.
A professional SEO audit examines three core areas, technical health, content quality and backlink profile, and combines the findings into a single prioritised report.
Covers crawlability, indexation status, Core Web Vitals, mobile usability, site architecture, structured data and broken links. Tools such as Google Search Console, Screaming Frog and Ahrefs identify indexing errors and crawl anomalies, though the value comes from interpreting the data, not just running the crawl.
Evaluates keyword targeting against actual search demand, title tag and metadata quality, content depth against top-ranking competitors, and content gaps where a topic has no coverage at all.
Assesses the quality and relevance of inbound links, flags toxic or spammy links that could be suppressing rankings, and benchmarks link profile strength against direct competitors.

| Feature | Free / automated audit | Paid professional audit |
|---|---|---|
| Analysis | Software-generated, surface-level | Human-reviewed, contextual |
| Prioritisation | Generic severity labels | Ranked by actual business impact |
| Competitor context | Rarely included | Usually included |
| Recommendations | Generic, templated | Specific to your site and market |
A free or automated audit is a reasonable starting point to understand whether deeper investment is worthwhile, but treat it as a lead indicator, not a decision-making document. The main limitation is that software cannot judge whether your content is actually good, whether your backlinks are actually relevant to your industry, or which of fifty flagged issues will move your rankings and which are cosmetic.
| Site size | Typical turnaround |
|---|---|
| Small (under 50 pages) | 1 to 2 weeks |
| Medium (50–500 pages) | 2 to 4 weeks |
| Large / e-commerce (500+ pages) | 4 to 6 weeks |
| Enterprise (multi-market) | 6 to 10 weeks |
Turnaround depends on site size and how much manual sampling is required, not just page count. A 40-page site built on a custom CMS with poor documentation can take longer to audit than a 200-page site on a clean WordPress install. Add one to two weeks to any of the above if competitor benchmarking or a live walkthrough call is included.
An SEO audit is a one-off diagnostic: it tells you what's wrong and what to prioritise, but it does not fix anything itself. Acting on the findings, publishing content, building links, fixing technical issues, is ongoing work, typically priced as a monthly retainer rather than a one-off fee.
If you are weighing up an audit against committing to an ongoing programme, our SEO Pricing UK 2026 guide breaks down what monthly retainers cost by budget band, from £500 entry-level work up to £8,000+ enterprise programmes, so you can see the full picture before deciding where to start.
In practice, most businesses that invest in a proper audit go on to implement at least the highest-priority findings themselves or through a retainer. Budgeting for both from the outset, the audit as a fixed one-off cost, and a realistic monthly figure for the work that follows, avoids the common mistake of paying for a great diagnosis and then having no budget left to act on it.
These patterns show up across every price point in the audit market and are worth checking for regardless of what you are quoted.
No sample report available
A provider who cannot show a redacted example of a previous audit, at any price point, is asking you to buy blind. Every legitimate provider keeps de-identified samples to share.
The report is just a tool export
If the deliverable is a raw Ahrefs, Semrush or Screaming Frog export with no interpretation or prioritisation added, you have paid consultant rates for a software subscription.
Every issue is marked as equally urgent
A report where everything is flagged "critical" has not actually been prioritised. Part of what you are paying for is judgement about what matters most for your specific site.
No walkthrough or Q&A included
A PDF dropped in your inbox with no explanation assumes you already understand SEO well enough to interpret the findings yourself, which defeats much of the point of paying for expertise.
The audit conveniently recommends exactly what the provider sells
Be cautious of an "independent" audit that concludes you need precisely the retainer package the same provider is trying to sell you. A genuinely objective audit should be usable even if you take the findings to a different provider to action.
Pricing scales with keyword count, not audit depth
Tracking 500 keywords is not meaningfully more expensive than tracking 50. If a quote scales primarily with keyword volume rather than site size or scope, the pricing structure is designed to look justified rather than reflect real effort.
Ask exactly what's covered. Technical, content, backlinks, competitors, get it in writing before paying, not as a verbal assumption.
Ask who will actually do the work. Get a senior specialist's name, not "our team", and ask about their relevant experience.
Request a sample report. A redacted example from a previous client lets you judge depth and prioritisation quality before you commit.
Confirm what happens after delivery. Is a walkthrough call included, and is there a window for follow-up questions once you have had time to read the findings?
Check whether competitor analysis is included or extra. This is one of the most commonly upsold components in an audit quote.
Ask how findings are prioritised. By severity, by effort required, or by estimated business impact, the answer tells you a lot about the provider's approach.
A professional SEO audit in the UK typically costs £400 to £10,000+ depending on site size and scope. Most small and medium-sized businesses pay £1,500 to £3,000 for a comprehensive technical, content and backlink audit. E-commerce and larger sites typically run £3,000 to £8,000, and enterprise audits start at £8,000 and can exceed £15,000 for very large, multi-market platforms.
A comprehensive SEO audit covers three core areas: technical health (crawlability, indexation, Core Web Vitals, site architecture), content quality (keyword targeting, metadata, content gaps), and backlink profile (link quality, toxic links, competitor benchmarking), combined into a single prioritised report.
A free or automated audit is a reasonable starting point but cannot judge content quality, backlink relevance or genuine prioritisation. Treat it as an initial indicator of whether deeper, paid investigation is worthwhile, not as a decision-making document on its own.
Freelancers typically charge £35 to £150+ per hour and suit a single, well-defined audit with direct access to the specialist doing the work. Agencies charge £75 to £300+ per hour but bring broader tool access and a second reviewer. For most small businesses, a senior freelancer or small specialist agency offers the best value for a one-off audit.
Turnaround typically runs 1 to 2 weeks for a small site under 50 pages, 2 to 4 weeks for a medium site, and 4 to 6 weeks for a large or e-commerce site. Enterprise, multi-market audits can take 6 to 10 weeks.
An SEO audit is a one-off diagnostic that identifies and prioritises issues. Ongoing SEO is the implementation work, content, links and technical fixes, typically priced as a monthly retainer rather than a fixed fee. Most businesses need both: an audit to set direction, and ongoing work to act on it.
Yes, for most small businesses that have never had a professional review. An audit typically costs a fraction of a year's ongoing SEO spend and prevents months of work being directed at the wrong priorities. The exception is a business with an extremely limited budget that would be better served putting the same money directly into one or two known, obvious fixes.
