“Website audit” sounds like a single service, but in practice it covers everything: from a free report generated in your browser in 30 seconds to a multi-day, manual analysis of an entire site. That is why “how much does an audit cost?” gets such scattered answers — it is not one product, but a whole shelf of different depths. Below we break down what a proper audit should include, how to tell a valuable one from a hollow one, and what really drives its price.
What a proper audit should cover
A good audit looks at your site from four angles at once — because visibility problems rarely have a single cause. Here are the four areas whose absence should raise a flag:
1. Technical SEO
The foundation users don’t see, but Google does. This covers:
- indexing (whether Google can see all your pages, whether anything blocks the crawler),
- URL structure, redirects and 404 errors,
- sitemap and robots file,
- meta titles and descriptions (present, not duplicated, not truncated),
- structured data and technical basics that affect how the site appears in results.
This is the most common source of “the site exists, but it’s nowhere in Google”.
2. UX and conversion
A site can be technically excellent and still not sell. Here we analyse:
- user paths — whether it’s easy to get from entry to contact or purchase,
- clarity of the offer (whether in 5 seconds it’s clear what the company does and for whom),
- calls to action, forms, the number of steps to conversion,
- the mobile version — today usually the majority of traffic.
3. Performance and Core Web Vitals
Speed is now a ranking factor and a real reason people abandon sites. The audit measures Core Web Vitals (time to content, layout stability, responsiveness to clicks), asset weight and the specific places that slow loading down.
4. Content and accessibility
Finally, what humans and screen readers actually read: quality and structure of content, headings, missing image alt text, contrast and accessibility basics (WCAG), plus security hygiene — how up to date the system and plugins are.
A tool report is not yet an audit
The most important distinction, and the one that saves disappointment. An automated report from a free or cheap tool spits out a list of “errors” and a score. It can be useful as a signal, but it has three flaws: it doesn’t tell a critical problem from a cosmetic one, it generates false alarms and — most importantly — it doesn’t tell you what to do about it.
An expert audit begins where the tool ends: someone interprets the data in the context of your business, filters out the noise, sets priorities and turns them into an action plan. The difference is like the one between a blood test result and a conversation with the doctor who tells you what to do next.
A practical test of an audit’s value: do you know, at the end, what to do first? If you get an 80-page PDF with no priorities, you have a report, not an audit.
What drives the price of an audit
Short answer: audit prices range from free automated tool reports to paid, multi-day expert analyses — because entirely different products hide under the same name. At Invisio, a full expert audit (technical SEO, UX, performance, content) costs PLN 2,900 net (≈ €660) for a website of up to around 30 pages and PLN 4,500 net (≈ €1,030) for an online store — details below.
Since it isn’t one product, the price depends on a few variables — which is exactly why it varies so much:
- Automated or expert — a tool report can be free; human analysis costs that person’s time.
- Scope — technical SEO alone is one thing; a full review of SEO + UX + performance + content is many times the work.
- Size and complexity of the site — auditing a one-pager versus a large shop with thousands of pages is a different scale.
- Form of the output — a raw list of remarks, or a structured document with priorities and recommendations.
- Whether the audit ends with a plan or with implementation — diagnosis alone is cheaper; an audit tied to fixing the issues is a different conversation.
So instead of asking “how much does an audit cost”, it’s worth asking: what exactly do I get, and will I know what to do next. A low price for an automated report and a high one for an expert audit isn’t overpaying — they’re two different products.
What to require from a good audit
Before you order an audit, make sure you’ll get:
- priorities — what to fix first, because it has the biggest impact,
- concrete recommendations, not just a list of errors,
- business context — remarks tied to what the site is meant to achieve,
- plain language — an output you’ll understand, not only a developer,
- clarity on what’s urgent and what can wait.
How we do it at Invisio
Our audit has a fixed price agreed upfront, with no hourly meter: PLN 2,900 net (≈ €660) for a website of up to around 30 pages, delivered in 5 business days, and PLN 4,500 net (≈ €1,030) for an online store, delivered in 8 business days. It covers all four areas described above — technical SEO, user paths and forms, performance (Core Web Vitals), and content and accessibility — and ends with a PDF listing the changes by priority, followed by a wrap-up call. Euro amounts are approximate, converted at the National Bank of Poland (NBP) rate of 5 October 2026 (EUR 1 = PLN 4.3855) and rounded.
Scope and process are described on our UX and SEO audit service page. Don’t confuse it with our free cost audit, which looks at hosting, domains and email rather than at the website itself.
