What is a CRO audit?
A CRO audit looks at the site you already have traffic on and asks why more of that traffic does not turn into enquiries or sales. It is a different question to "why am I not ranking", and it needs a different kind of look.
What a CRO audit actually is
CRO stands for conversion rate optimisation - the practice of increasing the share of visitors who complete the action you want, whether that is a purchase, a booking, a quote request, or a phone call. A CRO audit is a structured review of a website through that lens: not "is this page well written" or "does this page rank", but "does this page make it easy and obvious for a real visitor to do the thing they came to do, and the thing you want them to do". It looks at the path a visitor actually walks, the friction along it, and the signals that make them trust you enough to act. It assumes the traffic is already arriving and asks where it leaks.
What it examines: clarity, friction and trust
A CRO audit starts with value proposition clarity - can a first-time visitor tell within seconds what you do, who it is for, and why you rather than a competitor. From there it looks at friction: forms with more fields than the task needs, checkout flows with unnecessary steps, calls to action that are vague ("Learn more") instead of specific ("Get a quote"), and pages that ask a visitor to do two or three different things at once instead of one clear thing. Trust signals get checked too - reviews, credentials, a real address or ABN, clear pricing or a clear next step - because a hesitant visitor with no reason to trust you will quietly leave rather than convert.
What it examines: speed, mobile and measurement
Page speed matters to CRO for a reason beyond search rankings - every extra second before a page is usable costs a measurable share of visitors who simply give up, particularly on mobile. Mobile experience gets its own look because most traffic to most small-business sites is now mobile, and a form or menu that works on a laptop can be genuinely unusable on a phone. The last piece is measurement: whether analytics and funnel tracking exist at all, and whether they show where visitors actually drop off. Without that, every conversion fix is a guess rather than a targeted change.
How a CRO audit differs from an SEO audit
An SEO audit asks how to get more visitors to the site - indexability, rankings, content that matches what people search for. A CRO audit assumes those visitors already arrived and asks what happens once they are there. The two are complementary, not competing: a site that ranks well but converts poorly is filling a leaking bucket, and a site that converts well but nobody finds has nothing to convert. Most businesses have looked harder at the first problem than the second, simply because rankings are easier to check than a visitor’s actual experience of the page.
A practical self-audit you can run today
Open your own site on your phone, in a private browsing window, and walk the path a real customer would - find a price, request a quote, book, or buy. Count the fields on your main form or checkout step; anything past the essentials is a reason people abandon it. On every important page, ask what single action it is asking the visitor to take - if the honest answer is "three things", pick one and make it obvious. Time how long the page takes to feel usable, not just to finish loading. Then look near your main call to action specifically: is there a review, a credential, a guarantee, or anything else nearby that would make a stranger trust the click.
When to bring in tooling, and where a scan fits
Judgement gets you a long way on its own - walking the golden path yourself will surface most of the obvious friction. Tooling earns its place once you need to measure rather than guess: real analytics to see where visitors actually drop off, session recordings to watch real behaviour, or a scan that reads the public-facing signals - trust markers, page speed, mobile rendering, calls to action - in one pass instead of page by page. AuditHQ’s marketing suite is built for that second layer: the free scan reads conversion and trust signals from your public site in about 60 seconds. It is a fast baseline against those signals, not a substitute for funnel analytics on your own traffic - pair the two rather than picking one.
Frequently asked questions
How much does a CRO audit cost?
It depends entirely on the approach. A self-audit like the one above costs nothing but time. An automated scan reading public trust and conversion signals is typically free or low-cost. A full agency engagement - with funnel analytics, session recordings, and structured A/B testing - is a genuine project with a proposal and a price attached, and the right choice scales with how much revenue is actually running through the site. Start with the free layers and only pay for the deeper engagement once you know it is warranted.
What is the difference between a CRO audit and an SEO audit?
An SEO audit is about getting more visitors to find the site - indexing, rankings, and content matching what people search for. A CRO audit is about what happens once a visitor is already on the site - whether the page makes it easy to act. They answer different questions and both matter; a site strong in one and weak in the other is still leaving results on the table.
How long does a CRO audit take?
A self-audit walkthrough of your key pages takes under an hour. An automated scan of trust and conversion signals takes about a minute. A full agency-led audit with funnel analysis and testing typically runs over several weeks, because it needs enough real traffic data to draw reliable conclusions before recommending changes.
Do I need a lot of traffic before running a CRO audit?
No. The self-audit walkthrough and a public-signal scan work on any live site regardless of traffic volume, because they assess the page itself rather than visitor behaviour data. Funnel analytics and A/B testing genuinely do need meaningful traffic to produce reliable numbers, which is why they are usually the second step rather than the first.
