- The price depends on the size of the site, the depth of the work and who does it.
- Crawling a site is cheap. The value of a paid audit is in diagnosis and a prioritised plan.
- Ask every provider exactly what you'll receive, and whether fixes are included.
- Many small business sites get most of the value from a tool plus a focused manual review.
How much does an SEO audit cost?
There's no standard SEO audit cost, because "SEO audit" covers very different pieces of work: an automated report generated in minutes, a few days of an experienced consultant's time, or a multi-week project for a large site. Prices range from free to several thousand in any currency.
What you're really buying is one of three things:
| Option | Typical cost | What you get | Best for |
|---|---|---|---|
| Do it yourself | Free tools; your time (roughly a day for a small site) | Your own findings, using Search Console, GA4 and PageSpeed Insights | Small sites, confident marketers, tight budgets |
| Audit tool or platform | About $129–$139 a month for an all-in-one SEO suite such as Semrush, Ahrefs or SE Ranking (less if paid yearly); a desktop crawler such as Screaming Frog is £199 a year | An automated crawl and issue list, often with monitoring | Ongoing checks; spotting problems early |
| Freelance or agency audit | Most often $75–$100 an hour; one-off SEO projects most commonly cost $2,501–$5,000. More for large or complex sites | A specialist's diagnosis and a prioritised plan | Migrations, sudden traffic drops, complex sites, or no time in-house |
The cost of a paid audit is mainly people's time. So the questions that matter are how many days of work you're paying for, and what you'll have at the end.
What changes the price
- Site size. A 30-page services site is a different job from a 5,000-page site with a blog, resources and multiple languages.
- Scope. Technical only, or technical plus content, on-page, local, links and competitors? Each area adds time.
- Depth. A tool export with comments, or a diagnosis of why problems exist and what to do about them?
- Platform and complexity. JavaScript-heavy sites, custom builds, ecommerce filters and international set-ups take longer to audit.
- Who does it. Rates vary with experience and location. A specialist who has handled many migrations charges more than a generalist, and is often worth it for that kind of work.
- Deliverables. A written report, a prioritised action list, a call to walk through it, developer tickets, or help implementing the fixes.
- Urgency. A sudden ranking drop or a migration deadline usually costs more.
What a good SEO audit includes
Whatever you pay, a useful audit should cover these areas, at the depth your site needs:
- Crawling and indexing: robots.txt, noindex, sitemaps, redirects, canonicals, broken links. See our technical SEO audit checklist.
- On-page: title tags, headings, content depth and overlap on your key pages.
- Speed and mobile: Core Web Vitals and the mobile experience.
- Content: which pages earn their place, which overlap, and what's missing. See how to do a content audit.
- Local: your Google Business Profile and listings, if you serve particular areas.
- Links and authority: who links to you, and how that compares with competitors.
- Competitors: why the sites above you are ahead. See website competitor analysis.
- Measurement: whether Search Console and GA4 are set up to show what's working.
And most importantly:
- A prioritised action list, ranked by impact and effort, not a raw export of every warning.
- The reason behind each recommendation, so you can judge it.
- Clear ownership: what you can do, what needs a developer, and roughly how long each takes.
Red flags in an audit quote
- A long automated report with a logo on it, and no explanation of what matters most.
- Guaranteed rankings. No one can guarantee a position in Google's results.
- No access requested. A serious audit needs Search Console and analytics access; without them it's guesswork.
- The audit is free, but every finding leads to an expensive retainer. Free audits can be useful, but judge the recommendations on their merits.
- No mention of your goals. An audit should start from the pages and searches that bring enquiries, not from a generic checklist.
Do you need a paid audit?
A paid specialist audit is worth it when:
- you're about to redesign, re-platform or change domain
- traffic or enquiries have dropped sharply and you can't see why
- the site is large, complex or international
- nobody in the business has the time or experience to do it
A tool plus your own review is usually enough when:
- the site is a typical small business site
- you want to keep on top of problems month by month
- you mainly need to know what to fix first
Our guide to doing a website audit walks through the do-it-yourself version step by step.
What to ask before you buy an SEO audit
- How many days of work is this, and who does it?
- What exactly will I receive: a report, an action list, a call, developer tickets?
- Which areas are in scope, and which aren't?
- Will recommendations be prioritised by impact on traffic and enquiries?
- Is implementation included, or quoted separately?
- Can I see an example audit (anonymised) you've done for a similar business?
- What access do you need from me?
Questions
How much does an SEO audit cost?
Anything from free (doing it yourself with Google's tools) to a monthly tool subscription, to a one-off fee for a specialist that depends on the size of the site and the depth of the work. Ask for the number of days and the exact deliverables to compare quotes.
Why do SEO audit prices vary so much?
Because the work varies. An automated report takes minutes; a specialist diagnosis of a large or complex site can take weeks. Site size, scope, depth, experience and deliverables all change the price.
Is a free SEO audit worth it?
It can be a useful starting point, especially from a tool that shows its findings clearly. Treat free audits offered as a sales lead with some caution, and judge each recommendation on its merits.
Can I do an SEO audit myself?
Yes. Google Search Console, Google Analytics and PageSpeed Insights are free, and a focused audit of a small business site's key pages takes around a day. Our step-by-step guide shows you how.
How often should I pay for an SEO audit?
Most small businesses don't need a paid audit every year. Use a tool or a monthly check to keep on top of problems, and bring in a specialist before a migration or when performance drops and you can't find the cause.
