CRO audit: turn more visitors, and the AI agents acting for them, into customers

How to do a CRO audit in 10 steps

To do a CRO audit, define your conversions, check your tracking, find your busiest leaking pages, map the funnel, watch real sessions, ask visitors what stopped them, review each key page, test your forms and checkout, check speed and mobile, then turn every finding into a ranked plan. A careful first pass takes a few days of focused work. Running an online store? The ecommerce CRO audit guide adds product, cart and checkout checks, and the Shopify CRO audit covers Shopify themes and apps.

1. Define what counts as a conversion

   Pick one primary action for each page type: a purchase, a lead form, a trial signup or a click to a merchant. Then list the smaller steps that lead to it, such as add to cart or starting a form. If you cannot name the primary action for a page, that is your first finding.

2. Check that your tracking tells the truth

   Compare the conversions in your analytics with the real number in your store, CRM or inbox for the same dates. If they do not match, fix the tracking before anything else. An audit built on wrong numbers sends you to the wrong pages.

3. Find the pages that matter

   Sort pages by traffic and by how many visitors leave from them. Pages that are both busy and leaky are where an audit pays off. On most sites that is a short list: the homepage, the top landing pages, product or pricing pages, and each step of the checkout or lead form.

4. Map the funnel and measure each step

   Lay out the path from landing to conversion and record how many people get through each step. Split it by device and by traffic source. A step that looks fine on desktop is often the one losing people on a phone.

5. Watch what people do

   Heatmaps show where visitors click and how far they scroll. Session recordings show hesitation, repeated clicks on things that are not links, and people hunting for information that is not there. Watch recordings of visitors who left at your weakest step.

6. Ask visitors what stopped them

   A one-question poll on a key page, or a short survey after purchase, tells you things no chart can. Read your support inbox, chat logs and reviews for the questions people ask before buying. Every repeated question is a gap on the page.

7. Review each key page by hand

   Go through each page as a first-time visitor on a phone. Is it clear what this is and who it is for? Is the next step obvious? Is there a reason to trust you near the point of decision? Does anything pull attention away from the main action?

8. Test your forms and checkout yourself

   Complete every form and place a test order. Count the fields and note each one you could remove or ask for later. Check error messages, payment options, shipping costs and what happens when something goes wrong.

9. Check speed, mobile and agent readiness

   Run your key pages through Google's PageSpeed Insights and load them on a real phone on mobile data. Then view the page source: if your prices, product details or policies only appear after scripts run, AI agents and some crawlers may not see them.

10. Turn findings into a ranked plan

    For each problem, write a hypothesis: what you will change, what you expect to happen, and why. Rank them with a simple score (below). Fix obvious breakages straight away and A/B test everything you are unsure about.

Common CRO audit findings

Most CRO audits find the same families of problems: unclear messaging above the fold, weak or competing calls to action, too many form fields, surprise costs at checkout, trust signals placed far from the buying decision, and pages that are slow or awkward on a phone. Which one costs you most depends on your site, which is why the evidence matters.

• Unclear first screen. A visitor cannot tell what you sell, who it is for or what to do next without scrolling.
• Competing calls to action. Several buttons of equal weight, so none of them stands out.
• Long or confusing forms. Fields that could be asked later, unclear errors, required phone numbers.
• Surprises at checkout. Shipping costs, forced account creation or missing payment options revealed at the last step.
• Trust in the wrong place. Reviews, guarantees and returns information hidden in the footer instead of near the button.
• Broken tracking. Analytics that double count or miss conversions, so decisions rest on wrong numbers.
• Mobile friction. Small tap targets, layouts that jump while loading, pop-ups that cover the page.
• Content agents cannot read. Prices, stock or policies that only appear after scripts run, or no structured data.

CRO audit vs UX audit vs SEO audit

A CRO audit asks why visitors who already arrived do not convert. A UX audit asks how easy the site is to use, whether or not that affects revenue. An SEO audit asks why people cannot find the site in search. They overlap, but each one is judged by a different number.

Quick CRO audit checklist

Use this short CRO audit checklist to run a first pass on any key page. Each line is a yes or no question. Every "no" is a finding to score and fix or test.

• Conversions in analytics match real orders or leads for the same dates
• The page says what it is, who it is for and what to do next on the first screen
• There is one main call to action, and it is visible on a phone without scrolling far
• Reviews, guarantees and returns information sit near the decision, not only in the footer
• Every form field is needed now, and error messages say how to fix the problem
• Total cost, shipping and delivery time are clear before checkout
• The page loads quickly on mobile data and does not jump while loading
• Tap targets are easy to hit and nothing covers the page on a phone
• Prices, product details and policies are in the page HTML, with accurate structured data
• AI crawlers you want are allowed in your robots file

These ten checks are a first pass.

To run the same eight checks on one landing page, such as the page an ad sends people to, use the landing page analyzer.
