What a Real CRO Audit Looks Like (And Why Most Are Useless)

Every agency offers a CRO audit.

Most of them are a PDF with screenshots, generic best-practice recommendations, and a list of things to "test." The client reads it, nods, and files it away. Nothing changes.

That's not an audit. That's a proposal with extra steps.

A real CRO audit answers one question: where is your site leaking revenue, and what do you fix first?

Here's what that actually requires.

What Most CRO Audits Get Wrong

Before covering what a good audit looks like, let's be direct about what passes for one at most agencies.

The heuristic audit. Someone browses your site for a few hours and writes down things that "look wrong." No data. No funnel analysis. Just opinions dressed up as expertise.

The best practices list. "Add urgency to your CTAs." "Show trust badges at checkout." "Use social proof near the fold." These might all be true. But they're generic. They don't account for your audience, your product category, or your specific drop-off patterns.

The screenshot deck. 40 slides of annotated website screenshots with red circles and arrows. Looks thorough. Rarely leads to a prioritized action plan.

None of these tell you how much revenue you're leaving behind or what to fix first.

What a Real CRO Audit Covers

1. Analytics Verification

Before analyzing any data, you verify the data is accurate.

This means:

• Is Google Analytics 4 tracking all sessions and events correctly?
• Is e-commerce tracking counting every transaction — or missing some?
• Are there tag firing issues in GTM?
• Are filters excluding real traffic?
• Is the attribution model reflecting how your customers actually buy?

We've found that 60–70% of e-commerce sites have meaningful tracking gaps. Checkout events miscounted. Conversion confirmation pages firing twice (double-counting). Mobile sessions attributed to the wrong source.

If the data is wrong, every recommendation built on it is wrong. This step isn't optional.

2. Funnel Analysis

Map the full conversion funnel — from first touch to purchase confirmation.

For each stage, measure:

• Drop-off rate: What percentage of visitors leave at this step?
• Absolute volume: How many people are at each stage?
• Time between stages: Where do people stall before moving forward?

The goal is to find the step with the highest volume of drop-offs. That's where optimization has the most leverage.

A 5% improvement at the top of the funnel compounds through every step below it. A 5% improvement at checkout only affects buyers who already got there.

3. Traffic Quality Analysis

Not all traffic belongs in your funnel analysis.

Segment your traffic by:

• Source/medium (paid search vs. organic vs. email vs. direct)
• Device type (mobile vs. desktop — these often have dramatically different conversion rates)
• New vs. returning visitors
• Geographic location (if you have regional inventory or shipping constraints)

You're looking for segments where conversion rate or RPV is dramatically different from the average. These signal either an opportunity (high-intent segment you could invest more in) or a problem (low-quality traffic dragging down overall numbers).

4. Page-Level Behavior Analysis

For the highest-traffic pages in your funnel, go deeper than pageview counts.

Use heatmaps, scroll maps, and session recordings (tools like Hotjar, Microsoft Clarity, or FullStory) to understand:

• Are visitors reaching the CTA, or leaving before they see it?
• Which product images or descriptions get the most attention?
• Where do people pause, re-read, or backtrack?
• What's the most common exit point on the page?

Quantitative data tells you what is happening. Behavioral data tells you why.

5. Checkout Funnel Deep-Dive

The checkout is where the most recoverable revenue lives.

Step through each stage:

• Cart review
• Account creation / guest checkout option
• Shipping information
• Payment information
• Order confirmation

For each step: what's the exit rate? Which fields are causing form abandonment? Is the shipping cost reveal causing a spike in exits? Is payment failure handled gracefully?

Common findings: a required account creation step killing 30% of checkouts. A shipping cost that appears only at step 3. A broken promo code field. A payment gateway that doesn't support the user's preferred method.

These aren't hypotheses. They're specific, measurable problems with known fixes.

6. Mobile Experience Review

Mobile traffic often represents 60–70% of visits for e-commerce stores. Mobile conversion rates are typically 2–3x lower than desktop.

That gap is your opportunity.

Audit the mobile experience specifically:

• Page load speed (Core Web Vitals on mobile)
• Tap target sizes (buttons too small to tap accurately)
• Form inputs (does the right keyboard appear for each field type?)
• Product image quality and zoom behavior
• Checkout flow on small screens

Mobile isn't a scaled-down version of desktop. It needs its own audit.

7. Prioritized Recommendations

This is where most audits fall apart.

A real audit ends with a prioritized action plan, not a list of 40 suggestions in random order.

Prioritization should be based on:

• Estimated revenue impact (how much is this problem costing you?)
• Implementation effort (quick fix vs. engineering sprint)
• Confidence level (backed by data vs. hypothesis)

The output: a ranked list of specific changes, each with a stated rationale and an expected impact range. The client knows what to do first, second, and third — and why.

What You Should Receive After an Audit

At minimum:

✅ Confirmation that your analytics tracking is accurate (or a list of what needs to be fixed)

✅ A visual funnel map showing drop-off rates at each stage

✅ Identification of the 3–5 highest-impact problems

✅ Behavioral evidence (heatmaps, session recordings, or specific data points) for each problem

✅ Prioritized recommendations with estimated impact

✅ A testing roadmap — which changes to A/B test and which to implement directly

If you're not getting these, you're getting a document — not an audit.

How Long a Real Audit Takes

Expect a thorough audit to take 7–10 business days for a standard e-commerce site.

Anything faster is cutting corners. A two-hour "audit" is a quick browse with a list of impressions. That has value — but it's not the foundation for a serious optimization program.

The Cost of Not Auditing Properly

Here's the real risk of a shallow audit: you optimize the wrong things.

You spend three months testing button colors on a product page when the real problem is a broken checkout on mobile. You run 10 A/B tests on your homepage while your cart abandonment rate sits at 82%. You fix copy when the tracking is miscounting half your conversions.

Every hour you spend optimizing the wrong thing is an hour you didn't spend fixing something that would have actually moved revenue.

A proper audit costs more upfront. It saves months of wasted optimization effort.

Final Thought

A CRO audit isn't a deliverable. It's a diagnostic.

The goal isn't to produce a PDF. It's to answer: where is the money going, and how do we get it back?

If your audit doesn't start with verified data, map the funnel, and end with a prioritized action plan — it's a best-practice slideshow.

Useful? Maybe. Sufficient to actually grow revenue? No.
