There are two numbers circulating for what a technical SEO audit costs, and they are eighty-five times apart. Survey data says most businesses pay a few hundred dollars. Agency pricing pages quote several thousand. Both numbers are real. Neither is wrong. They are measuring different products that happen to share a name — and the gap between them is why every quote you receive feels arbitrary.

This guide reconciles the two. It uses published industry figures where they exist, explains what the price actually buys at each level, and shows you how to read a proposal so you stop comparing quotes that were never comparable.

The short answer

Businesses report paying $101–$750 for an SEO audit. The largest agencies charge $8,600 for one. The difference is not margin — it is scope, depth, and whether a human interprets the crawl. For a mid-sized e-commerce store, a technical audit worth acting on realistically costs $500–$5,000 one-time, depending on template count, rendering method, and whether server logs are in scope.

What businesses report paying

WebFX surveyed 250 U.S. businesses on audit spend and published the results. Their headline finding: 43% of businesses pay $101–$750 for an SEO audit. Their breakdown by company size:

Business size	Reported spend	Note
Startup / micro-enterprise (1–10 staff)	$50 – $750	Lowest ceiling of any bracket.
Small business (11–50 staff)	$1 – $2,500	A $1 floor indicates a survey artefact.
Mid-sized business (51–250 staff)	$50 – $2,500	Overlaps almost entirely with the bracket above.
Large business (251–500 staff)	$101 – $5,500	Highest ceiling in the dataset.
Enterprise (501+ staff)	$501 – $4,000	Ceiling is lower than the bracket beneath it.

Read this data carefully

These are the best publicly available figures on audit spend, and they are worth citing. They are also worth reading sceptically, for three reasons.

The brackets are minimum-to-maximum, not percentiles. With roughly 50 respondents per size band, a single unusual answer sets each endpoint. That is how you get a $1 floor.
The curve is non-monotonic. Enterprise tops out at $4,000 while Large tops out at $5,500. Real cost curves do not behave that way, which suggests the sample per band is too small to be stable.
“SEO audit” is undefined in the question. A respondent who bought a $50 automated tool report and one who commissioned a four-week engineering review both answer the same field.

The practical takeaway is not the number. It is that most businesses are buying at the shallow end of the market — which tells you what most businesses receive, not what a diagnosis costs.

What the largest agencies actually charge

The same page that reports a $101–$750 range sells its own audit for $8,600, delivered over 45 days. The published scope: up to 70 pages reviewed, a competitive scorecard covering three competitors, keyword research on up to 50 terms, backlink reporting, and 2.5 hours of implementation support. An in-depth link audit is a $1,200 add-on; a link acquisition strategy is another $500.

That is roughly eleven times the top of the range the same publisher reports as typical. Nobody is being deceived here — the survey measures what the broad market buys, and the pricing table sells a specific enterprise product to a specific enterprise buyer. But it demonstrates the core problem better than any argument could: the word “audit” spans an order of magnitude, on a single page, from a single company.

The number that matters more than the price Up to 70 pages reviewed. For a brochure site that is comprehensive. For an e-commerce catalogue with 5,000 URLs it is a 1.4% sample — which may be entirely appropriate if those 70 pages are chosen as template representatives, and close to meaningless if they are not. Always ask how the sampled pages are selected. Template coverage matters; page count does not.

What a premium checklist reveals about the industry

Published audit checklists are unusually informative, because they show you what an agency believes technical SEO consists of. The $8,600 checklist referenced above lists roughly 33 analysis items. Several of them audit features that no longer exist.

It checks the Search Console preferred domain setting. Google removed that setting in 2019.
It checks Search Console URL parameter exclusions. Google deprecated that tool in 2022.
It refers to Google Webmaster Tools throughout. The product was renamed Google Search Console in 2015.

It also retains diagnostics from an earlier era of the discipline — code-to-text ratio, shared IP address checks, whether JavaScript and CSS are called remotely — that have little bearing on how a modern store ranks.

More consequential is what the list does not contain. Set the covered items against what actually determines e-commerce visibility in 2026:

On the checklist	Absent from the checklist
Site load time (average and home page)	Core Web Vitals — LCP, INP, CLS
Broken links, 301 redirects, HTTP status codes	Rendered DOM compared against raw HTML
Robots.txt configuration	AI crawler access — GPTBot, ClaudeBot, PerplexityBot, OAI‑SearchBot
Sitemap.xml configuration and index rate	Server log file analysis of actual crawler behaviour
Static / dynamic URL configuration	Faceted navigation and crawl-trap mapping
Canonicalisation	Structured data validation across templates
Duplicate content	Hreflang and multi-market indexation
Title tag optimisation	Mobile-first indexing parity

The point is not that this particular agency is careless — they employ hundreds of specialists and their delivery may well exceed their published checklist. The point is that a premium price tag is not evidence of a current methodology, and the checklist is the only part of a proposal that tells you which one you are buying. Ask for it before you sign anything.

One question that filters most proposals “Will you compare our rendered HTML against the raw server response, and will you test whether AI crawlers can access our product pages?” If the answer is vague, the audit is scoped for a version of search that ended several years ago — whatever it costs.

Why the same job gets quoted tenfold apart

Two variables account for almost all price variance, and neither is the agency’s brand.

Crawling is cheap. Interpretation is not.

Running a crawler against 5,000 URLs takes twenty minutes of machine time and almost no human attention. Reading that crawl — deciding which of the 400 flagged issues suppress revenue, which are cosmetic, and which are false positives created by the crawler’s own configuration — is where the hours go. An audit priced at the cost of the crawl is, structurally, one that has skipped the reading.

Cost scales with templates, not pages

A 200,000-URL store built from eight templates is often faster to audit than a 3,000-URL store with sixty bespoke landing pages. Technical problems live in templates, faceted navigation rules and rendering behaviour, not in individual products. An agency quoting purely off URL count is pricing the wrong variable — which usually means it is pricing the crawl rather than the analysis.

What the work costs when it is done properly

The tiers below describe what the labour supports at each price point for an e-commerce store. They are a framework for evaluating quotes, derived from delivery hours rather than from a market survey — use them to interpret a proposal, not as a published benchmark.

Tier	Indicative cost	What the hours buy	Right for
Tier 1 Automated	Under $500	Crawler export plus a PageSpeed and Search Console skim. Issues ranked by tool-assigned severity. Little manual verification, no rendering check, no logs.	A sanity check on a small site, or a second opinion when you already have in-house SEO capacity.
Tier 2 Diagnostic	$500 – $1,500	Above, plus manual verification of every material finding, indexation analysis against Search Console, canonical and pagination logic review, internal link and crawl-depth analysis, and a priority-ordered fix list with effort estimates.	Most Shopify, WooCommerce and BigCommerce stores under roughly 25,000 URLs, single market, single template family.
Tier 3 Forensic	$1,500 – $5,000	Above, plus server log file analysis, rendered-versus-raw HTML comparison, faceted navigation and crawl-trap mapping, structured data validation across templates, hreflang auditing, AI crawler access testing, and developer-ready remediation tickets.	Larger catalogues, headless or JS-heavy builds, multi-market stores, or any site where traffic dropped and nobody can explain why.
Tier 4 Enterprise	Above $5,000	Above, plus stakeholder interviews, platform constraint mapping, pre- or post-migration risk analysis, a phased implementation roadmap, and working sessions with the engineering team.	Migrations, replatforms, marketplace-scale catalogues, or organisations where the fix must survive a quarterly planning cycle.

Where the reported figures land on this scale The $101–$750 that most businesses report paying sits in Tier 1 and the very bottom of Tier 2. That is consistent with a market in which most buyers receive a crawler export and conclude that audits do not achieve much. Observed demand supports the framework: fixed-price technical audit briefs on freelance marketplaces in mid-2026 commonly sit between $1,000 and $3,000, and increasingly specify log analysis, hreflang and rendering work by name. Treat that as a qualitative signal, not a statistic — marketplace budgets are opening offers and skew below agency pricing.

What a real deliverable contains

Price tells you less than the deliverable does. A credible audit above Tier 1 should contain all six of the following. If a proposal does not name them, ask before comparing it to anything else.

1. A prioritised issue register — not an issue list

Every finding ranked by estimated revenue impact and implementation effort, so your developer knows what to do first. A flat list of 300 issues hands the hard decision back to you — which is the decision you were paying to have made.

2. Evidence attached to each finding

Screenshots, crawl segments, log samples or Search Console exports. A finding without evidence is an opinion, and your developer will treat it as one.

3. Rendered-HTML analysis

What Googlebot and AI crawlers see after JavaScript executes, compared against the raw response. This catches the most expensive failure in e-commerce SEO — content that exists for users and not for crawlers.

4. Indexation reconciliation

Submitted versus indexed versus impression-earning URLs, with the gaps explained. This is where wasted crawl budget and orphaned templates surface.

5. Implementation specifications

Not “fix your canonicals” but the specific rule, the templates affected, and the expected output. The difference between an audit that ships and one that gets filed is almost entirely here.

6. A re-test plan

How each fix will be verified, and when. Without it you have no way to know whether you bought a result or a document.

Which tier does your store need?

Your situation	Tier	Why
Traffic is stable; you want a health check before scaling ad spend	Tier 2	You need prioritisation, not forensics.
Organic traffic dropped and nobody can explain the cause	Tier 3	Cause-finding needs logs and rendering comparison.
Store is headless, React-based or heavily JavaScript-dependent	Tier 3	Rendering behaviour is the primary risk surface.
Replatforming or migrating domains within two quarters	Tier 4	Pre-migration analysis costs a fraction of post-migration recovery.
You sell across multiple countries or languages	Tier 3+	Hreflang and market-level indexation add real scope.
You have in-house SEO and want a second opinion	Tier 1–2	You already own the interpretation layer.
Your products are missing from AI assistant answers	Tier 2–3	AI crawler access and entity consistency need direct testing.

Red flags at any price point

The report exceeds 100 pages and under 20 of them are specific to your site. Boilerplate padding is a volume-shop signature.
Findings are reproduced verbatim from the crawler’s own issue descriptions, generic explanation text included.
Nobody asked for Search Console or analytics access. An audit without your performance data is an audit of a stranger’s site that happens to share your URL.
Severity comes from the tool rather than your business. “Critical” on a crawler dashboard is frequently cosmetic in revenue terms.
The checklist has not been updated for Core Web Vitals, rendering, structured data or AI crawlers.
Implementation is bundled and mandatory before any diagnosis exists. You cannot scope a fix you have not diagnosed.
The audit is only available free, inside a retainer. A diagnosis with no standalone price has an incentive problem.

The cost nobody quotes: implementation

An audit is a diagnosis. The bill for treatment is separate and usually larger. Budget for it before you commission the audit, or you will own an expensive document.

Developer time to implement the fixes — frequently a multiple of the audit fee for a Tier 3 remediation set.
Platform limitations forcing workarounds. Some Shopify and hosted-cart constraints cannot be fixed, only routed around.
Content and template work where the fix is editorial rather than technical.
Re-testing and verification after deployment.

A useful budgeting rule: if you cannot fund implementation, buy a smaller audit. A Tier 2 audit you act on outperforms a Tier 4 audit you shelve, every time.

Frequently asked questions

How much does a technical SEO audit cost?

For most e-commerce stores, $500–$5,000 as a one-time engagement. Published survey data puts 43% of businesses at $101–$750, but that figure spans every audit type including automated tool exports. Large agencies price productised audits considerably higher — $8,600 is a published example.

Why do quotes for the same site vary by tenfold?

Because “audit” describes at least four different products, from a crawler export to a multi-week engineering engagement. Ask every provider two questions — how many page templates will you analyse, and will you examine rendered HTML or raw HTML — and most of the variance explains itself.

How long should a technical SEO audit take?

A diagnostic audit runs 5–10 business days; a forensic one 2–4 weeks, since log file collection depends on your host. Industry timelines of 30–45 days are commonly quoted, but that reflects agency queue depth more than the work itself.

Should I accept a free audit bundled with a retainer?

It is genuinely useful for catching obvious failures — a noindex left on staging, a malformed robots.txt. But a diagnosis provided at no cost has an incentive to recommend the service being sold alongside it. Insist the audit is purchasable standalone, even if you then buy the retainer.

Which type of audit should I buy?

The narrowest one that addresses your actual symptom. A 360-degree audit spanning technical, content, link, competitive and social work is the most expensive option and is often sold as the default — but if your products are not indexing, a social audit contributes nothing.

Does a technical SEO audit cover AI search visibility?

Usually not. Traditional audits verify Googlebot access, not GPTBot, ClaudeBot, PerplexityBot or OAI-SearchBot. If AI visibility matters to you, confirm it is in scope in writing.

What is the difference between a technical SEO audit and a GEO audit?

A technical audit asks whether crawlers can reach and render your pages. A GEO audit asks whether AI systems can extract, attribute and cite what is on them. Overlapping inputs, different pass conditions.

How do I know the audit was any good?

Ask for a redacted sample before you buy, and ask how each fix will be verified after deployment. No re-test plan means no way to tell whether you bought a result or a report.

The bottom line

Price is a poor proxy for quality here, because the same word covers a crawler export and a four-week engineering engagement. What separates them is how much human judgement sits between the tool output and the recommendation you receive — and whether the checklist behind it describes search as it works now.

Before accepting any quote, ask for two things: the analysis checklist, and a redacted sample deliverable. Three minutes with either will tell you more than any pricing page.
