How Much Does a CRO Audit Cost? Published Prices and What You Get

Ask five agencies what a conversion rate optimization (CRO) audit costs and you'll get five answers, often "it depends" followed by a sales call. That makes it hard to budget, and hard to tell whether a quote is fair.

This guide uses only prices that vendors publish on their own pages, so you can see the real range. It also covers what drives the price, what a good audit should include, and the one thing nearly every one-off audit leaves out. We sell an ongoing alternative, explained at the end, but the advice before that stands on its own.

Published CRO audit prices

Few agencies list prices publicly. These do. Prices checked October 27, 2026, in US dollars, as listed on each vendor's site.

For a wider view, Convert, which makes A/B testing software, in an article updated April 2026, puts a one-time conversion audit at $2,500 at the low end, $3,500 on average and $4,500 at the premium end, with monthly CRO retainers running from $2,000 to $30,000 (Convert).

So a human-led audit of one page or funnel usually costs somewhere in the low thousands of dollars, and research-backed audits cost more. Ongoing agency programs are priced per month on top of that. Agency Immersive, for example, lists its basic CRO program at $3,950 a month.

What drives the price

Scope

One landing page costs less than a whole site, and a whole site costs less than several funnels across markets. Before comparing quotes, check how many pages, templates or conversion paths each one covers.

Research depth

A cheaper audit is often an expert review: someone experienced walks through your page against a list of known problems. More expensive audits add analytics review, session recordings, surveys, user testing, or scoring against a benchmark of other sites. More research generally means more confidence in the findings.

Who builds the fixes

Some audits are a report only, and you or your developer make the changes. Others include implementation, or credit the audit fee toward a retainer. Two audits at the same price can leave you with very different amounts of work.

Follow-up

Some include a readout call. Few include checking, weeks later, whether the fixes actually worked.

What a good audit includes

Whatever you pay, a useful audit should give you:

• Evidence for each finding. "The headline is weak" is an opinion. "Most visitors never scroll to the form" is a finding.
• A ranked list. You can't fix everything at once. The audit should say what to fix first and why.
• Specific changes. "Improve trust" isn't actionable. "Add the returns policy under the buy button" is.
• A clear scope and deadline. You should know exactly which pages are covered and when you'll get the report.

The gap every one-off audit has

An audit is a snapshot. It tells you what looked wrong on the day someone reviewed your site. Two things happen after that.

First, you ship some of the fixes, and you need to know whether they worked. Without a before-and-after measurement, you're left guessing, especially on a smaller site that can't run A/B tests. (Our guide to measuring fixes without A/B testing shows how to do it yourself.)

Second, your site keeps changing. New pages, new apps, new campaigns and new traffic sources create new problems that the original audit never saw.

That doesn't make audits a bad buy. It means you should plan for measuring results after the audit, either by doing it yourself or by paying for it.

Questions to ask before you pay for an audit

1. Which pages or paths are covered, exactly?
2. Is the review based on my visitors' actual behavior, an expert's judgment, or both?
3. Will findings be ranked, and will each one say what to change?
4. Who makes the changes, and is that included?
5. Will anyone check whether the fixes worked, and is that included?
6. What happens if I'm not happy with the report?

Can you do it yourself?

Often, yes, at least for a first pass. Pick your highest-traffic page, check it on a phone, and work through a structured list. Our guides to why a landing page isn't converting and the Shopify product page checklist walk through the most common problems in order. Then make one change at a time and compare equal periods before and after.

A paid audit is worth considering when you've done the obvious fixes, when the cost of a wrong guess is high, or when you simply don't have the time.

Where Cortality fits (and what it costs)

Cortality isn't a one-off human audit. It's ongoing measurement: one tag measures how real visitors use every part of your page and gives you a ranked list of fixes, each with the exact change to make. After you ship a fix, it re-measures and tells you whether the change worked: improved, worse, no change, or not enough data yet. See what a finding looks like, or read how our landing page CRO audit works.

Plans run month to month: Starter is $99/month (one page, up to 2,500 visitors a month), Growth is $249/month and Scale is $499/month, with custom Enterprise pricing for agencies and 6+ sites. Start your free week, and you can switch plans at any time, during the trial or after. You save a card at signup, you see your first report before you pay, and nothing is charged until 3 days after that report. Cancel before then and you pay nothing, and any charge can be refunded within 14 days. Details are on our pricing page and in the refund policy. Results vary from site to site.

Not ready for that? Start with the free page leak scan. It shows where your page is likely losing buyers and what fixing it could be worth, in about a minute, with no install or card. It's a prediction from our attention model, not data from your visitors.

FAQ

How much does a CRO audit cost?

Among vendors that publish prices, we found a one-time Shopify app audit at $199, agency audits of a page or funnel at roughly $1,450 to $5,000, and research-firm audits at $7,000 and $10,900 (prices checked October 27, 2026).

Why do CRO audit prices vary so much?

Scope (how many pages or paths), research depth (expert review vs analytics, recordings, surveys and user testing), whether implementation is included, and whether anyone follows up to measure results.

Is a cheap or free audit worth it?

It can be a useful first pass, as long as you know what it is. Quick audits usually review the page against common problems rather than your visitors' real behavior. Use them to find obvious issues, then measure whether your fixes work.

Is an audit better than ongoing measurement?

They do different jobs. An audit gives a one-time expert view. Ongoing measurement keeps tracking real visitor behavior and checks whether each fix worked. Many teams benefit from both.
