How Much Does an SEO Audit Cost, and What Should It Include?

An SEO audit costs nothing for an automated tool report, low thousands of dollars for a manual audit of a small or mid-sized site, and well into five figures for an enterprise review; the most common one-off SEO project fee is $2,501-$5,000, according to Ahrefs' survey of 439 SEO providers. The price follows the depth of the work, not the page count of the report. A real audit ends with prioritised findings, evidence for each one and a clear plan for who fixes what.

This guide covers the three price tiers, what each one delivers, why a free report is not an audit, and the questions to ask before you pay for one. For the cost of ongoing SEO work after the audit, see my breakdown of SEO consultant cost and pricing models.

What are the three tiers of SEO audit pricing?

SEO audits fall into 3 tiers, separated by how much human judgment goes into the result. The tiers below describe what you pay for at each level.

Tier 1: Automated reports (free to a few hundred dollars)

An automated SEO report costs $0 to a few hundred dollars because software produces it in minutes. Several reputable tools give site owners this tier for free or close to it:

• Google Search Console, which is free and shows indexing, Core Web Vitals, security issues and manual actions from Google's own data.
• Ahrefs Webmaster Tools, whose Site Audit "scans your website for 170+ common technical & on-page SEO issues" on verified sites, with 5,000 crawl credits a month per project (Ahrefs, Webmaster Tools page).
• Screaming Frog SEO Spider, which crawls up to 500 URLs free, with a paid licence at £199 per year (Screaming Frog, pricing page).

Most "free SEO audit" offers from agencies are one of these exports with a logo on the cover, used to start a sales conversation.

Tier 2: Manual audit for a small or mid-sized site (low thousands)

A manual SEO audit for a typical business site sits in the low thousands of dollars, and the $2,501-$5,000 bracket is the single most common project fee in the market. Ahrefs' SEO pricing survey of 439 providers (Joshua Hardwick, updated August 2024) found that 21.2% of respondents charge $2,501-$5,000 per project, and 60.6% charge $1,001 or more. The survey covers all one-off SEO projects, not audits alone, so treat it as the market range for fixed-scope work of which audits are the most common example.

The same data shows who charges what. Freelancers most commonly charge $101-$250 per project, agencies $2,501-$5,000 and consultants $5,001-$10,000. Experience moves the number sharply: providers with 2 years or less in business averaged $1,881.73 per project, against $9,087.31 for those with 5-10 years.

Tier 3: Enterprise and complex sites (five figures and up)

Enterprise audits cost five figures or more because the crawl, the data and the stakeholders all multiply. Ahrefs found that some US and Canadian providers charge $50,001-$75,000 per project. Sites in this tier share three traits: tens or hundreds of thousands of URLs, a custom or headless stack, and several teams that must agree before any fix ships. Faceted ecommerce navigation, international hreflang setups and JavaScript-rendered catalogues push a site into this tier faster than page count alone.

What should an SEO audit include?

A real SEO audit delivers a ranked list of problems, the evidence behind each one, an estimate of impact and effort, and implementation notes specific enough for someone to act on. Google's own guidance on hiring an SEO sets the bar in one sentence: "An SEO audit should be about giving you realistic estimates of improvement, and an estimate of the work involved" (Google Search Central, Do you need an SEO?, updated 2026).

The scope of areas checked (indexing, on-page content, speed, security, AI search readiness and tracking) is covered in full in my 40-point website audit checklist. What separates a paid audit from that checklist is the deliverable. Expect these 5 components:

1. An executive summary that names the 3-5 issues costing the most traffic or revenue, in plain language.
2. Prioritised findings scored by impact and effort, so a high-impact, low-effort fix (a wrong canonical tag on 2,000 product pages) comes before a low-impact, high-effort one (rewriting every alt attribute).
3. Evidence for every finding: the Search Console report, the crawl export, the URL examples and the screenshot that prove the problem exists.
4. Root causes, not symptoms: "the theme outputs a second H1 in the header template", not "142 pages have duplicate H1s".
5. Implementation notes that state the exact change, the file or setting it lives in, who makes it and how to verify it worked in Search Console afterwards.

A 200-page PDF without the second and fifth items is a crawl export, whatever the cover says.

Why is a free SEO audit not a real audit?

A free automated report lists symptoms that software detects; an audit explains which symptoms matter on your site, why they exist and in what order to fix them. Tools flag everything that matches a rule, so a healthy site routinely shows hundreds of "issues" that change nothing in search.

Three gaps make automated reports misleading on their own:

• No prioritisation. A missing meta description and a noindex tag on your best service page appear as two equal line items.
• No context. A tool flags 300 "duplicate" pages without knowing that they are intentional location pages with correct canonicals.
• Lab data instead of real users. Speed scores in automated reports come from a single simulated load. Google states that lab data "is based on a simulated load of a page on a single device and fixed set of network conditions" and "may not capture real-world bottlenecks" (Google, About PageSpeed Insights).

Free reports are still useful. Run one before you hire anyone, because it gives you a baseline to judge whether a paid auditor found more than the software did.

Does an SEO audit include fixing the problems?

Most SEO audits do not include fixing anything; the standard deliverable is a report, and implementation is quoted separately or handed to your developer. That split is where audit value leaks away. A report that waits 3 months in a developer's ticket queue delivers 3 months of nothing.

Ask before you buy whether the price covers any of these 3 levels of implementation:

• Report only: findings and recommendations, with no hands on the site.
• Report plus developer tickets: findings rewritten as specific tasks your developer picks up, with acceptance criteria.
• Report plus fixes: the auditor makes the changes in the CMS, templates or server configuration and verifies them.

Compare quotes on the total cost to a fixed site. A cheap audit that needs 40 developer hours to implement costs more than a pricier one where the auditor ships the fixes. My guide on what a technical SEO consultant fixes explains the implementation gap in more depth.

What do most SEO audits miss?

Most SEO audits stop at what a crawler reports and skip the code-level root causes and the security checks that explain the symptoms. This is the gap I see most often, because I work across all three areas: SEO since 2020, production code since 2016 and security research since 2011.

Code-level root causes

A crawler sees the HTML a page returns. It does not see the template, plugin or build step that produced it. Three examples show the difference:

• A slow Largest Contentful Paint traced to a slider plugin that loads its JavaScript on every page, including pages with no slider.
• Thousands of thin URLs generated by a filter or search parameter that the framework exposes to crawlers.
• Missing content in Google's index because a JavaScript framework renders the main text only in the browser.

Each one needs someone who reads PHP, JavaScript or the framework's routing to fix, not only to report. A finding that reads "reduce unused JavaScript" without naming the file that ships it leaves your developer to repeat half the audit.

Security

Security problems surface as SEO problems first. Google's spam policies define hacked content as "any content placed on a site without permission, due to vulnerabilities in a site's security", and injected spam pages compete with your real pages in the index. A firewall rule that blocks Googlebot looks like an indexing drop. An outdated plugin looks like nothing at all until it is exploited.

An audit that skips the Security Issues report, a site: search for pages you did not create and a review of outdated software misses one of the fastest ways a site loses rankings. A site that fails those checks needs the steps in what to do when your website is hacked.

What questions should you ask before buying an SEO audit?

Ask every auditor the same 7 questions and compare the written answers. Each question below exposes a different weakness:

1. Can I see a sample deliverable? An anonymised past audit shows whether you get prioritised findings or a crawl export.
2. Which tools and data sources do you use? Search Console and analytics access belong on the list, alongside a crawler.
3. How do you prioritise findings? Expect an impact-and-effort method, not a severity colour from a tool.
4. Do you review templates, code and server configuration? A "no" means root causes stay hidden.
5. Do you check security issues? The answer separates a full audit from a keyword review.
6. Who implements the fixes, and is that included? Get the answer in writing, with any separate cost.
7. What access do you need? Google advises granting an auditor "read access to Search Console (at this stage, don't grant them write access)".

These questions overlap with the broader interview in my guide on how to hire an SEO consultant, which covers ongoing engagements rather than one-off audits.

Frequently asked questions

How much does an SEO audit cost?

An SEO audit costs $0 for an automated tool report, low thousands of dollars for a manual audit of a typical business site, and five figures or more for an enterprise site. The most common one-off SEO project fee is $2,501-$5,000, according to Ahrefs' survey of 439 SEO providers.

What is included in an SEO audit?

A real SEO audit includes an executive summary, findings ranked by impact and effort, evidence for each finding, the root cause behind each issue and implementation notes. Google states that an audit should give "realistic estimates of improvement, and an estimate of the work involved."

Is a free SEO audit worth it?

A free SEO audit is worth running as a baseline, because tools such as Google Search Console and Ahrefs Webmaster Tools show real technical issues at no cost. It is not a substitute for a paid audit, because it lists symptoms without prioritising them or finding their cause.

How long does an SEO audit take?

An automated report takes minutes, while a manual audit takes days to weeks depending on site size, stack complexity and access to data. Large sites with custom code take longest because the auditor traces issues back to templates and server configuration.

Does an SEO audit include security?

Most SEO audits do not include security, which leaves a gap, because hacked content, blocked crawlers and outdated plugins all damage rankings. Ask the auditor directly whether they check the Search Console Security Issues report and look for injected spam pages.
