What is a conversion audit? A plain-English guide for store owners

What a conversion (CRO) audit is, what it checks, what it costs, and how AI audits compare with hiring a CRO agency or doing it yourself.

Quick answer

A conversion audit (or CRO audit) is a structured review of a website to find what stops visitors from buying. It checks the first impression, trust signals, navigation, product pages, mobile layout, page speed and checkout, then gives a prioritised list of fixes. Audits can be done by a CRO agency (usually hundreds to thousands of dollars), by yourself with a checklist, or automatically by AI tools such as StorePeek in a couple of minutes.

Key takeaways
  • An audit tells you what to fix. A/B testing tells you which fix works best. Audit first.
  • Good audits rank issues by impact, so you know where to start.
  • AI audits are fast and cheap enough to repeat every month. Agency audits go deeper into your analytics and customers.

What a conversion audit checks

A thorough conversion audit looks at your store the way a first-time visitor does, and then the way a sceptical one does. The usual areas are:

AreaWhat gets checked
First impressionHeadline clarity, hero image, call to action above the fold, pop-ups
TrustReviews, policies, contact details, payment badges, guarantees
NavigationMenu labels, search, filters, dead ends
Product pagesPhotos, descriptions, pricing clarity, variant selection, add-to-cart visibility
MobileReadability, tap targets, layout on small screens
SpeedCore Web Vitals: LCP, INP, CLS
CheckoutHidden costs, guest checkout, payment options, form friction

Agency audits also usually dig into your analytics (funnel drop-off, device and traffic-source splits) and sometimes customer surveys.

Conversion audit vs A/B testing

They solve different problems. An audit finds the issues: "your shipping costs are hidden until checkout". An A/B test compares two versions to see which performs better: "free shipping over $50 vs flat $4.95 shipping".

A/B tests need a lot of traffic to give reliable answers. Small and mid-sized stores often don't have enough, which makes an audit, plus fixing the obvious problems, the more practical first step.

For most small stores the sensible path is to run an AI audit, fix the high-severity issues, and bring in a specialist once traffic is large enough for testing to pay off. If you prefer to do it yourself, start with our 40-point conversion checklist.

How StorePeek's AI audit works

  1. 1You paste your store URL. No code, app install or store access is needed.
  2. 2A real Chrome browser opens your store on desktop and on a phone, captures the first impression, then closes cookie and newsletter pop-ups.
  3. 3AI reviews the screenshots against a conversion checklist, and Google PageSpeed measures load performance.
  4. 4You get a friction score, a performance score and a list of issues ranked High, Medium or Low, each with a specific fix.

The free check covers your homepage and shows the top three issues. Premium adds product page analysis, an estimate of sales lost, PDF reports and monthly re-checks. Try it on your store.

What makes an audit actually useful

  • Specific fixes, not "improve trust". A good finding says what to change and where.
  • Prioritisation. Twenty findings with no order is a to-do list you won't finish.
  • Mobile and desktop separately. They fail in different ways.
  • Repeatability. Your store changes, so the audit should be easy to run again.

Frequently asked questions

How much does a conversion audit cost?

A DIY audit is free. AI tools range from free to a small monthly fee (StorePeek is free for one audit, then from $9.99 a month). Agency CRO audits typically cost from a few hundred to several thousand dollars depending on depth.

How long does a CRO audit take?

An automated AI audit takes a minute or two. A DIY review with a checklist takes a few hours. An agency audit usually takes one to several weeks.

Is a conversion audit the same as an SEO audit?

No. An SEO audit looks at how easily search engines find and rank your pages. A conversion audit looks at what visitors do once they arrive, and why they don't buy. Most stores need both.
