Why We Use Zestly for CRO Audits on Every Client Website
Most businesses that come to us asking for help with their ads have the same problem. The ads are not the problem. The landing page is.
You can spend $5,000 a month on Google Ads and drive highly qualified traffic to a page that loads slowly, has a confusing layout on mobile, and buries the contact form below 900 words of copy. The ads will perform poorly and everyone will blame the campaigns. The campaigns are fine. The website is the bottleneck.
A CRO audit identifies exactly where the website is losing people and why.
What CRO Actually Means
CRO stands for Conversion Rate Optimisation. The conversion rate is the percentage of visitors who complete a desired action: filling in a contact form, making a purchase, booking an appointment. Optimising it means finding and fixing the things that are preventing visitors from converting.
The average website conversion rate across industries sits between 2 and 5%. If your site is getting 1,000 visitors a month and 10 of them convert, you have a 1% conversion rate. Fixing the site to get that to 2% doubles your leads without spending another dollar on traffic.
Most businesses focus entirely on driving more traffic. A CRO audit asks a different question: of the traffic you already have, how much are you capturing, and what is getting in the way of the rest?
What Zestly Analyses
Zestly is a CRO audit tool that gives us a structured analysis of a website across the dimensions that matter most for conversions.
Page speed. This is the first thing Zestly checks because it is the one that kills conversions before they even start. A page that takes 5 seconds to load on mobile loses more than half its visitors before they see anything. Zestly measures load time against benchmarks and flags pages that fall below the threshold.
Form friction. Every additional field in a form reduces conversion rate. Zestly audits forms for the number of fields, the clarity of field labels, the quality of validation messages, and whether the form is positioned well on the page. A 6-field contact form where a 3-field version would do the same job is a friction point that costs conversions.
Trust signals. Does the site show testimonials, reviews, credentials, or social proof near the conversion points? Trust signals directly influence whether a first-time visitor decides to act or leave. Zestly surfaces pages where trust signals are absent or poorly positioned.
Mobile UX. More than half of web traffic is mobile. Zestly checks whether buttons are large enough to tap reliably, whether text is readable without zooming, whether forms work properly on touch screens, and whether the mobile layout buries important information below the fold.
Call to action clarity. A page with 4 different CTAs competing for attention is a page where visitors do not know what to do next. Zestly analyses CTA presence, placement, and hierarchy. The best-converting pages have one primary action that is obvious and easy to take.
The Friction Points Zestly Has Surfaced for Our Clients
The issues Zestly surfaces are not always the ones clients expect.
A common finding is a fast desktop site with a slow mobile experience. The desktop version loads in 1.8 seconds. The mobile version takes 4.5 seconds because images are not being served at mobile-appropriate sizes. The client has been checking their site on a desktop and assuming it is fine.
Another common finding is form placement. A service page that drives significant traffic has a contact form at the very bottom, below a lengthy explanation of the service, the team, the process, and the FAQ. Visitors who arrive ready to enquire cannot find the form without scrolling past everything else. Moving the form up the page, or adding a second instance above the fold, changes the conversion rate without changing anything else.
Zestly has also surfaced missing trust signals on pages that drive direct revenue. A pricing page with no testimonials, no client logos, and no guarantee or risk-reversal messaging is asking visitors to commit without reassurance. Adding a single relevant testimonial near the CTA is one of the fastest conversion improvements available.
How We Use Audit Results to Prioritise Fixes
Not every finding from a Zestly audit gets fixed before a campaign launches. There are always more issues than time. The question is which fixes will have the most impact on the metrics that matter.
We prioritise in this order: load speed issues (because they affect every visitor), CTA clarity (because it is usually fast to fix and has broad impact), form friction (because it directly affects the conversion action), and trust signals (because they are high-impact but require content).
Fixes that take less than an hour and directly affect the conversion path are done immediately. Fixes that require design or content changes get scheduled. Fixes that are nice-to-haves but not blocking conversions get noted for a future iteration.
The audit output gives us a ranked list with severity levels. That list becomes the briefing document for the pre-launch website work.
Why We Run It Before Every New Campaign Engagement
We do not start a Google Ads or Meta campaign without running a CRO audit on the destination first. The reason is simple. Advertising drives traffic to a page. If the page converts at 1%, the campaigns carry that ceiling. If we can get the page to 2.5% before spending on ads, the same budget produces 2.5 times the leads.
Running the audit after the campaign has launched is possible but less efficient. You are spending money to drive traffic to an unoptimised page while you figure out what to fix. Running it before means the campaigns launch into a better environment from day one.
This is not a complicated principle. The website and the ads are part of the same system. Both need to be working before you should expect the system to perform.
If you are thinking about running ads and want to know whether your website is ready to convert the traffic, start with an audit. We will tell you exactly what needs to be fixed and in what order.
