An SEO audit costs anything from nothing (doing it yourself with free tools) to five figures (an enterprise agency engagement). For a small or mid-sized business, a professional audit with prioritised, implementable fixes typically falls in the $500 to $5,000 range, depending on site size, depth and who does it. The useful question isn't the average price; it's what you get at each level.
The short answer
| Option | Typical cost | What you actually get |
|---|---|---|
| DIY with free tools | $0 plus your time | Crawl data and Google's indexing data; you do the analysis |
| DIY with paid tools | ~£199/year (Screaming Frog) to ~$1,400–$1,700/year (Semrush or Ahrefs suites) | Better data and scheduled crawls; you still do the analysis |
| Automated report / low-cost freelancer | Under ~$500 | Usually a tool export with light commentary |
| Experienced freelancer or productized audit | ~$500–$5,000 | Expert analysis, prioritised fixes, often a walkthrough |
| Agency or enterprise audit | $5,000 to $15,000+ | Large sites, many stakeholders, workshops, implementation support |
What the pricing surveys say (and why they disagree)
Two surveys of SEO providers are worth knowing, and they don't agree:
- Ahrefs surveyed 439 SEO providers worldwide (published December 2023, since updated). The most common fee for a one-off SEO project was $2,501–$5,000, and the average hourly rate was $111.
- SE Ranking and Duda surveyed agencies for their 2024–2025 pricing report. The most common project fee was $500–$2,000, covering about two-thirds of respondents; only 4% charged over $10,000. The authors note their sample leans towards smaller agencies.
Both are "right" for their samples. Neither isolates audits from other projects such as migrations or keyword research, so treat them as a range, not an average. If you see a single precise "average audit price" quoted without a linked source, be sceptical. We found one widely repeated figure attributed to a survey we couldn't locate.
What you get at each price band
Price tracks three things: how many URLs are analysed, how much of the work is human judgement, and whether the output is implementable.
Under $500. Expect a tool-generated report, sometimes rebranded, with a health score and a list of issues sorted by the tool's own severity labels. Useful as a starting checklist. Rarely includes Search Console analysis, cannibalisation or prioritisation by business impact. You can produce much of this yourself with free SEO audit tools.
$500–$2,000. A competent freelancer or productized audit for a small site (tens to low hundreds of URLs). Should include crawl and Search Console analysis, a prioritised fix list and specific recommendations for key pages. If only one or two pages matter, a single-page deep audit costs less; TapasSEO's 360 SEO Page Audit is $297 for one URL.
$2,000–$5,000. A full site audit for a growing site: every URL in scope, cross-page issues (cannibalisation, indexation gaps, internal linking), backlink review, competitor gap, and a ranked action list developers can work from. As a transparent reference point, our Site SEO Audit is $1,497 for up to 50 URLs, $2,497 for up to 200 and $3,997 for up to 500.
$5,000 and up. Large or complex sites: tens of thousands of URLs, several languages, JavaScript frameworks, log-file analysis, multiple stakeholders, workshops and implementation support. Enterprise SEO audits sit here.
What drives the price
- Site size and complexity. More URLs, templates, languages and rendering complexity mean more analysis.
- Depth. Technical-only, or technical plus content, links, competitors and AI visibility.
- Data access. Search Console, analytics and server logs make a better audit and take time to analyse.
- Who does the work. Senior specialists cost more per hour but usually need fewer hours to reach the right priorities.
- Implementation detail. "Fix duplicate titles" is cheap to write; rewritten titles for 200 pages, redirect maps and schema code are not.
- Turnaround. Rushed timelines cost more.
- Tools. Professional suites cost $1,400–$1,700 a year each, and that's built into agency pricing.
Pricing models: fixed, hourly, retainer
- Fixed price — the most common for audits. You know the cost up front; check the scope (how many URLs, which areas) is written down.
- Hourly — common with consultants. The Ahrefs survey put the average at $111/hour. Ask for an estimate and a cap.
- Bundled into a retainer — some agencies include an audit in the first month of a monthly contract. Convenient, but you lose the ability to take the audit to another provider for implementation. Our guide to SEO cost covers retainers in detail.
Red flags at any price
| Red flag | Why it matters |
|---|---|
| Free audit that needs a sales call to receive | It's a lead magnet; expect a pitch, not a diagnosis |
| Report leads with a health score | Scores are tool-specific and say nothing about business impact |
| No Search Console access requested | They can't see what Google actually indexed |
| Issues not prioritised by impact | You'll spend weeks on fixes that don't move results |
| Recommends FAQ schema to win rich results | Google stopped showing FAQ rich results on 7 May 2026 |
| Recommends Google's Mobile-Friendly Test | Retired in December 2023 |
| Promises rankings | No audit can guarantee them |
| No examples of previous reports | You can't judge depth before paying |
How to choose an SEO audit company
Ask any provider, agency or freelancer:
- Can I see a sample report? (We publish ours: the stripe.com sample.)
- How many URLs are in scope, and what happens if my site is bigger?
- Will you use my Search Console data?
- How are findings prioritised?
- Will fixes be specific enough for my developer to implement without a meeting?
- Is a walkthrough call included?
- Who actually does the analysis?

Frequently asked questions
How much should a small business pay for an SEO audit? For a site with up to a few hundred pages, $500–$2,500 buys a solid professional audit with prioritised fixes. Below that, you're usually paying for a tool export you could run yourself.
Why do some agencies charge $10,000+ for an audit? Large sites, multiple markets and languages, log-file analysis, stakeholder workshops and implementation support. For a 50-page site that price buys mostly overhead.
Is a free SEO audit worth it? As a first look, yes. Free tools catch broken links, missing tags and speed issues. A free audit offered by an agency is usually a sales tool; useful, but expect it to be shallow.
What is a white-label SEO audit? An audit produced by one provider and delivered under another agency's brand. Agencies use them to offer audits without building the capability in-house. Check that the scope and data access match what you're promising your client.
How long does an SEO audit take? From a few days for a small site to several weeks for large or complex ones. Fixed-price productized audits typically quote a set number of business days.
Get a fixed, published price instead of a quote
Every agency page in this space anchors on its own number, and the two industry surveys above don't even agree with each other. TapasSEO skips the quote call: the price for your site size is published before you talk to anyone, it doesn't move once you're in a contract, and it isn't bundled into a retainer you can't take elsewhere.
