SEO audit services: what they include and what they cost

An SEO audit service is a paid, one-off review of a website that ends in a written list of problems, ranked by how much each one holds the site back in search. Done well, it tells you what is broken, why it matters, who should fix it and in what order. Done badly, it is a 200-page export from a crawler with a logo on the cover.

This page explains what SEO audit services should include, what they cost according to the published data, and how to tell the two kinds apart before you pay.

What does an SEO audit service include?

A complete SEO audit covers six areas: technical crawling and indexing, on-page content and metadata, site performance, links, analytics sanity, and how AI search systems can access and cite the site. It should end in a prioritised fix list with evidence for each item, not just a list of everything a tool flagged.

Area	What a good audit checks	Evidence you should see
Crawling and indexing	Status codes, redirects, robots.txt, canonical tags, sitemaps, JavaScript rendering, mobile rendering	Crawl data compared with Search Console’s Page indexing report
On-page and content	Titles, descriptions, headings, thin or duplicate pages, keyword cannibalization, internal linking	Example URLs for each problem, grouped by template
Performance	Core Web Vitals from real users, lab diagnostics for failing templates	Field data per template, not a single home page score
Links	Referring domains, anchor text patterns, lost links, risky patterns	Honest caveats about third-party link metrics
AI visibility	AI crawler access, snippet eligibility, content readable without JavaScript, entity markup	robots.txt and CDN rules tested against named crawlers
Measurement	Analytics and Search Console set up correctly, conversions tracked	A short note on what can and cannot be measured

The AI visibility row is newer and is where audits vary most. A good one tests whether crawlers such as OAI-SearchBot and PerplexityBot can actually fetch your pages, explained in the AI crawlers guide. A weak one recommends an llms.txt file as a priority. Google says llms.txt is not used by Google Search, so treat that recommendation as optional at best; the llms.txt guide covers what it can and cannot do.

What you should receive at the end

The deliverable matters more than the crawl. Ask to see a sample report before you commit, and check it contains:

• A one-page summary in plain language: the three to five issues that matter most and what fixing them is likely to change.
• A prioritised issue list, each item with severity, the URLs or templates affected, the fix, an owner (developer, content, marketing) and a rough effort estimate.
• Evidence, such as screenshots, response headers or Search Console exports, so your team can verify each finding.
• Implementation notes specific to your platform. “Add a canonical tag” is not enough; “change the theme’s head template so collection product URLs output the product canonical” is.
• A walkthrough call or recording, so questions get answered before work starts.
• A re-check of the fixed items, ideally included in the price.

Our view: if the report cannot be turned into tickets within an afternoon, it is too long or too vague.

How much do SEO audit services cost?

No independent survey tracks audit prices on their own. Published data on SEO services puts hourly rates mostly between $75 and $200, so an audit of a small site, which typically takes 10 to 20 hours, lands around $1,000 to $3,000. Large, international or JavaScript-heavy sites can reach five figures.

The data behind that estimate:

• Research shows that in a poll of 439 SEO service providers, the most common per-project fee was $2,501 to $5,000 (21.2% of respondents), and 47% charged between $75 and $200 an hour (Ahrefs SEO pricing survey). That covers all SEO projects, not audits alone.
• Research shows that most SEO firms listed on Clutch charge $100 to $149 an hour, and the usual cost of projects reviewed there is under $10,000 (Clutch SEO pricing guide, updated September 2026). This is directory data drawn from client reviews, not a market-wide survey.

Turning those rates into audit budgets is our estimate, not a published figure:

Provider and site	Typical effort	Indicative price (our view)
Automated tool report, any site	Minutes, no human review	Free to a low monthly subscription
Freelancer or consultant, small site under 500 URLs	10–20 hours	About $1,000–$3,000
Consultant or firm, mid-size or ecommerce site	25–60 hours	About $2,500–$9,000
Large, international or migration audit	60+ hours, often with log analysis	$10,000 and up

What moves a quote up or down: the number of templates (not pages), the platform, whether content depends on JavaScript, the number of languages or countries, access to server logs, and whether a re-check is included. A site with 50,000 product pages built on three templates can be cheaper to audit than a 2,000-page site built on twenty.

Questions to ask before you hire

Google says you should ask any SEO provider these questions, among others (Do you need an SEO?):

1. Can you show examples of previous work and results?
2. Do you follow Google Search Essentials?
3. What results do you expect, in what timeframe, and how will you measure them?
4. What experience do you have in our industry and our country or city?
5. Will you explain every change you recommend and why?

Add these audit-specific ones:

6. Which crawler and settings will you use, and will you crawl with JavaScript rendering on?
7. Who does the analysis, and is any of it outsourced?
8. What access do you need? Google’s guidance is that read access to Search Console is enough for an audit.
9. How do you assess AI visibility, and what evidence supports each recommendation?
10. Is a follow-up check after fixes included?

Red flags

• Guaranteed rankings. Google states plainly that no one can guarantee a first-place ranking.
• Secret methods, or claims of a special relationship with Google or “priority submission”.
• Link schemes or offers to submit your site to thousands of directories or search engines.
• Unsolicited audit emails. Google advises treating them with the same caution as other unsolicited offers.
• Score-only deliverables. A single number with no evidence is not an audit. See what a good SEO score means for why scores from different tools are not comparable.
• AI visibility promises backed by invented metrics or “guaranteed citations”. No one controls whether an assistant cites you.
• Requests for owner or write access before any work is agreed.

Free audit first, paid audit when

Our view: start with a free automated audit to triage. It shows whether the problems are the fixable-in-an-afternoon kind (missing descriptions, a noindex left on, a redirect chain) or the structural kind (indexing collapse, faceted navigation, a botched migration). The free audit at seouch.com is a sensible first step: it runs in about a minute without signup and shows the top issues straight away. If you want a person to look at the results, a strategist review can be requested from the report itself.

Pay for a human audit when the fixes need judgement: choosing between conflicting canonical strategies, planning a migration, or explaining a traffic drop the tools cannot.

What to do next

1. Run a free audit on your home page and one page from each template.
2. Fix the obvious errors yourself, then re-scan.
3. If structural problems remain, request sample reports from two or three providers and compare them against the deliverables list above.
4. Read technical SEO audit services if your problems are mostly crawling, rendering or performance.
5. Use the SEO audit guide to understand each step well enough to judge the work you receive.

Frequently asked questions

Is a free SEO audit good enough?

For a small site it often is. An automated audit finds most technical and on-page problems, and many of them you can fix yourself. A paid audit earns its fee when the issues are structural, such as an indexing drop, a migration or a large catalogue, and need someone to interpret the evidence.

How long does a professional SEO audit take?

As a rule of thumb, allow one to two weeks from granting access to receiving the report for a small site, much of it spent collecting crawl and Search Console data. Large or international sites can take four to six weeks, especially when server logs are included.

Should the audit include implementing the fixes?

Usually not. Most audits end with a prioritised fix list and a walkthrough. Implementation is quoted separately because it depends on your platform and who on your side makes the changes. Ask whether a follow-up check after fixes is included.

How often should I commission an SEO audit?

A full paid audit once a year, or before and after a redesign or migration, is enough for most sites. Between audits, a monthly automated scan and a look at Search Console catch new problems early.
