What is a CRO audit?
A CRO audit, short for conversion rate optimization audit, is a structured look at why the people who reach your site don’t go on to buy, sign up or get in touch. Analytics show you the numbers. An audit looks for the reasons behind them: confusing navigation, weak messaging, a form that asks too much, a page that drags on mobile.
The aim isn’t to list everything that could be better. It’s to find the problems costing you the most, so your team spends its time where the return is highest.
Choosing the right Fibr CRO agent
Fibr’s audit runs through one of three CRO agents, each looking at your site through a different lens. Pick the one that matches the problem you suspect:
Personalization. Best when very different visitors land on the same pages, for example traffic from several ad campaigns, industries or regions, and one version can’t speak to all of them.
Experimentation. Best when you have steady traffic and want to know what to test next, which elements to tune and what it takes to get a reliable result.
Web performance. Best when the site feels slow, behaves inconsistently across devices or loses people in ways that point to technical friction.
Not sure? Start with the agent closest to your biggest goal for the quarter. You can run the audit again with another agent at any time.
Which metrics matter in a CRO audit?
Metrics point to where the problem is. The audit explains why. Good places to start are conversion rate split by device and traffic source (an average can hide a broken mobile experience), drop-off between funnel steps, top exit pages, form starts versus completions, and load time on your most important pages.
Then look for the biggest gaps between segments, such as mobile versus desktop or paid versus organic. The widest gap usually hides the biggest win.
Why Fibr asks about your audience, competitors and ads
Generic audits produce generic advice: add social proof, shorten the form, speed up the page. All true, and none of it tells you what matters most for your business.
That’s why Fibr’s audit asks a few questions before it runs. Knowing who you sell to tells it which concerns your visitors are likely to have. Knowing your competitors shows what those visitors are comparing you with. And if you run ads, your keywords and ad copy let the audit check whether your site keeps the promises your ads make. The result is a set of recommendations written for your situation, not a checklist anyone could have downloaded.
