A CRO audit is a structured review of where a website loses visitors between arriving and converting, and why. I run every one the same way: fix the tracking, read the behaviour data, find the leaks on the pages that matter most, then rank the fixes by commercial impact.
The short answer
- A CRO audit finds the points where a website loses potential customers after the click, using analytics, behaviour data and page-by-page review.
- Conversion rate optimisation starts with tracking, because a team that cannot measure conversions accurately cannot improve them.
- Dead clicks, rage clicks, drop-off points, slow pages and broken forms are the most common signs of a revenue leak a CRO audit uncovers. Each one tells you where to look, not what caused it.
- Clear calls to action, visible trust signals and landing pages matched to their ads often fix conversion problems without a redesign.
- Free tools such as Microsoft Clarity and Google Analytics 4 are enough to start a website conversion audit on most business sites.
What is a CRO audit?
A CRO audit is a review of a website’s conversion paths that identifies why visitors do not take the action you want, such as enquiring, booking or buying. Conversion rate optimisation (CRO) is the ongoing work of fixing those causes. The audit produces a ranked list of problems and fixes, so effort goes where it moves the numbers.
Your website conversion rate is the number of conversions divided by the number of visitors (or sessions), multiplied by 100. Two hundred enquiries from 10,000 visits is a 2% conversion rate. The rate matters less than the trend and the gap between segments, such as mobile against desktop or paid traffic against organic.
CRO matters more every year. Pew Research Center found that Google users who saw an AI summary clicked a traditional result in 8% of visits, against 15% for users who saw none. As AI answers take more of the clicks, each visit that does arrive is worth more, and the sites that convert it well will win. That is what I call post-click value.
How do I run a CRO audit?
I run a CRO audit in two stages. First, stabilise: make sure tracking records real conversions and the site is fast and reliable. Second, diagnose: use analytics and behaviour data to find where visitors drop off, click on things that do nothing, or abandon forms, then rank each problem by its likely effect on leads or sales.
Make the site reliable and measurable first, then look for the leaks, and only then change things. When my team runs an audit, we read Microsoft Clarity behaviour data alongside speed and analytics to surface dead clicks, rage clicks, drop-off points, speed issues and tracking gaps. The steps:
- Check the tracking. Submit a test enquiry, make a test purchase, tap the phone number. Confirm each one appears in analytics as a conversion event. My guide to setting up Google Analytics 4 in WordPress covers the set-up.
- Stabilise the site. Fix outages, errors and anything that breaks checkout or forms before optimising anything else.
- Find the money pages. List the pages with the most traffic and the pages closest to conversion: service pages, product pages, landing pages, checkout, contact.
- Read the behaviour data. Use heatmaps and session recordings to find dead clicks, rage clicks, short scroll depth and form abandonment on those pages.
- Compare segments. Mobile against desktop, new against returning, each traffic source. Big gaps tell you where to look.
- Review each page against the checklist below.
- Rank and fix. Score each issue by impact and effort. Fix high-impact, low-effort issues first, and measure qualified enquiries or sales before and after, not just form submissions.
The order matters because the worst leaks are often not on the page. An online homewares retailer came to my team with a site that kept going down, and payments that were sometimes processed two or three times for one order. It had no analytics at all, so nobody could say what the outages were costing. Button and headline tests would have been theatre. The plan put a server audit, the payment fault and proper tracking first, and left the conversion work until the site could be trusted and measured.
I built PostCliq to make the first pass of this kind of audit faster. Its job is to find the revenue leaks after the click: it helps marketing teams spot potential leaks on their website and decide which improvements to prioritise. It is free to use.
For each finding, I would record the affected URL and device, the observed behaviour, the date and sample size, the proposed cause, the smallest useful fix, the owner and how success will be measured. Separate a proven defect, such as a form that fails to send, from a hypothesis, such as a headline that may be unclear. Record qualified enquiries or completed orders alongside the conversion rate, so a higher percentage of weaker leads does not look like a win.
What should a CRO audit checklist include?
A CRO audit checklist should include tracking accuracy, page speed, mobile usability, message match between ads and pages, calls to action, forms, trust signals, navigation and behaviour data. Each item names a common leak and the evidence that confirms it. Work through the checklist on your highest-value pages first, not across the whole site at once.
| Area | What to check | Possible leak signal |
|---|---|---|
| Tracking | Every conversion recorded once, with its source | Enquiries in the inbox that analytics never saw |
| Speed | Core Web Vitals on mobile for key pages | High exits before the page finishes loading |
| Mobile | Forms, menus and buttons usable with a thumb | Mobile conversion rate well below desktop |
| Message match | Landing page headline repeats the ad’s promise | High bounce from paid traffic |
| Call to action | One clear primary action, visible without hunting | Low clicks on the main button; clicks on non-links |
| Forms | Only essential fields, clear errors, working notifications | Form starts without submits |
| Trust | Reviews, real people, credentials, security, contact details | Visitors reach pricing or contact pages, then leave |
| Navigation | Key pages reachable in a few clicks | Repeated back-and-forth between menu pages |
| Behaviour | Dead clicks, rage clicks, scroll depth | Clusters of frustrated clicks on one element |
Many of these are user experience problems at heart. My guide to website user experience goes deeper on navigation, accessibility and UI.
How do you write a call to action that converts?
Write a call to action that converts by deciding the single action the page exists for, then describing the outcome the visitor gets in a few words that start with a verb. Place it where the visitor is ready to act, make it visually distinct from everything else, and test the wording against real conversion data rather than opinion.
- Set one goal per page. A confused page produces a confused visitor. Secondary actions can exist, but they should look secondary.
- Lead with the outcome. “Get my website review” says more than “Submit”. “Book a free call” says more than “Contact”.
- Start with a verb. Book, get, start, download, compare, request.
- Add the value or reduce the risk. “Free”, “no lock-in” or “reply within one business day” answer the doubt before it forms, but only if they are true.
- Make it stand out. Contrast and space, not shouting colours. It should be the most obvious thing to click.
- Place it where intent peaks. Near the top for visitors who arrive ready, and again after the explanation for those who need convincing.
- Put a relevant call to action on every important page, not only the home page. Blog posts, service pages and case studies each need a next step.
- Avoid false urgency. Fake countdowns and made-up scarcity erode the trust you need to convert.
Which trust signals should a website show?
A website should show trust signals that answer a first-time visitor’s doubts: genuine reviews and testimonials, real team photos and names, years in business, recognisable clients or media mentions where true, clear contact details, and visible security such as HTTPS. Place them close to the point of decision, especially beside forms and calls to action.
| Trust signal | Where it works best | Watch out for |
|---|---|---|
| Reviews and testimonials with names and photos | Beside forms and on service pages | Never invent or edit testimonials |
| Years in business, number of customers | Home page and about page | Keep numbers current |
| Client logos and media mentions | Below the first screen | Use only with permission |
| Team photos and names | About page and contact page | Stock photos undo the effect |
| Helpful content: guides, case studies, FAQs | Throughout the site | Content that pushes too hard reads as a sales pitch |
| Free trial, free consultation or guarantee | Near the main call to action | Offer only what you deliver |
| HTTPS and secure checkout | Site-wide, and visible at payment | Mixed-content warnings break trust instantly |
How do you build a landing page for ad campaigns?
Build a landing page for ad campaigns around one offer and one action, with a headline that repeats the promise in the ad. Cut distractions: many teams remove the main navigation, but test it, because some buyers want to check who you are before they enquire. Keep the form short, load fast on mobile, place trust signals beside the form and track the conversion as an event before any money is spent on traffic.
These landing page best practices apply whatever platform you use. On WordPress, follow these steps:
- Decide if you need a dedicated page. You need one when the offer needs its own explanation, the ad targets a specific audience, or you want to measure that campaign cleanly. Otherwise, send traffic to a strong existing page.
- Match the message. Same promise, same wording, same offer as the ad.
- Build it. The block editor with reusable patterns is enough for most landing pages. Page builders such as Elementor, Beaver Builder, Divi and SeedProd are faster for teams without a developer, but check that the page they produce is still fast.
- Keep the form short. Ask only what you need to follow up. A well-chosen form plugin makes validation, notifications and CRM connections easier.
- Test speed on mobile. Paid clicks are wasted on a page that loads slowly. Use free speed testing tools before launch.
- Set up conversion tracking. In analytics and in the ad platform, tested with a real submission.
- Launch, then test. Run split tests only when the page gets enough conversions to reach a reliable result. On low-traffic pages, test bigger changes or use behaviour data instead. Judge every result on qualified enquiries or sales, not raw clicks.
For Google Ads, the page also affects cost: landing page experience is one of the components of Quality Score, alongside expected click-through rate and ad relevance.
Which CRO tools work with WordPress?
The CRO tools that work well with WordPress fall into four groups: behaviour analytics (Microsoft Clarity, Hotjar, Crazy Egg), lead capture (OptinMonster, Thrive Leads), landing pages (Unbounce or WordPress page builders) and analytics (Google Analytics 4, Kissmetrics). Start with the free ones. Most sites find their biggest leaks before they need a paid tool.
| Tool | What it does | Free or paid |
|---|---|---|
| Microsoft Clarity | Heatmaps, session recordings, dead clicks and rage clicks | Free |
| Google Analytics 4 | Traffic, conversions and funnels | Free |
| Hotjar | Heatmaps, recordings and on-page surveys | Free plan and paid plans |
| Crazy Egg | Heatmaps, recordings and A/B testing | Paid, with a trial |
| OptinMonster | Pop-ups, opt-in forms and on-site campaigns | Paid |
| Thrive Leads | WordPress opt-in forms with split testing | Paid |
| Unbounce | Hosted landing page builder with testing | Paid |
| Kissmetrics | Customer-level product and revenue analytics | Paid |
| PostCliq | Finds potential revenue leaks after the click and prioritises fixes | Free to use |
Google Optimize, once the default free testing tool, was shut down by Google in September 2023, so remove it from any old checklist.
What to do next
- Submit a test conversion on every form and confirm it appears in analytics.
- Before collecting behaviour data, check what the tool captures, mask sensitive fields and exclude private account or checkout data that should not be recorded. Match your privacy notice and consent implementation to the audience and applicable rules. Microsoft documents Clarity’s consent controls; the OAIC explains Australian tracking privacy obligations. Then collect enough relevant activity to investigate the pages you are auditing.
- List your five highest-value pages and run the checklist above on each, on mobile first.
- Fix the top three leaks by impact and effort, and measure the change in qualified enquiries or sales against the baseline.

Frequently asked questions
What is a good website conversion rate?
A good website conversion rate depends on the industry, the offer, the traffic source and what counts as a conversion, so a single benchmark misleads more than it helps. Compare your site against itself: track the rate by page, device and channel, and aim to improve the weakest segment. A rising trend on your money pages matters more than any average.
How long does a CRO audit take?
A CRO audit for a typical business website can take a few weeks, depending on the scope and the evidence already available. Tracking checks and obvious defects can be reviewed in days. Behaviour data takes longer when traffic is low, and two to four weeks is a planning window, not a guarantee of reliable patterns. Agree which pages, devices and conversion paths will be examined, report the sample actually observed and mark recommendations based on limited evidence.
What is the difference between CRO and UX?
UX (user experience) is how easy and pleasant a website is to use. CRO (conversion rate optimisation) is the practice of increasing the share of visitors who take a specific action. They overlap heavily, because most conversion problems are UX problems. The difference is focus: CRO measures everything against conversions and revenue, and prioritises fixes by their commercial impact.
Do you need A/B testing to do CRO?
You do not need A/B testing to start CRO. Many leaks, such as broken forms, slow mobile pages, missing tracking and unclear calls to action, are obvious once you look at the data and can simply be fixed. A/B testing becomes useful when a page has enough conversions to compare versions reliably and the right answer is genuinely uncertain.
What are dead clicks and rage clicks?
A dead click is a click on something that does nothing, such as an image or text the visitor expected to be a link. A rage click is several rapid clicks on the same spot, usually a sign of frustration with an element that is slow or broken. Microsoft Clarity flags both automatically, and clusters of either on a key page are worth investigating as a possible conversion leak.
