What is conversion rate optimisation (CRO)?

Conversion rate optimisation (CRO) is the process of improving the percentage of website visitors who complete a desired action — such as making a purchase, filling out a form, signing up for a newsletter, or downloading a resource. CRO involves analysing user behaviour, identifying friction points in the customer journey, and testing changes to increase conversions without necessarily increasing traffic.

What methods does Prebo Digital use for CRO?

Prebo Digital uses a combination of methods including: (1) A/B testing and multivariate testing to compare page variations, (2) user research and heatmaps to understand visitor behaviour, (3) landing page optimisation to reduce friction, (4) funnel analysis to identify drop-off points, (5) form optimisation to increase completion rates, (6) copywriting and messaging refinement, and (7) technical optimisation for page speed and mobile experience. We prioritise tests based on potential impact and ease of implementation.

How long does it take to see CRO results?

CRO results depend on your traffic volume and test duration. A typical A/B test requires 2–4 weeks to reach statistical significance, depending on your conversion rate and traffic. Quick wins (form field removal, copy changes, button colour) can show results within days. Sustained CRO improvement typically requires 3–6 months of continuous testing and optimisation. We recommend starting with high-impact, low-effort tests and building a testing roadmap from there.

What is statistical significance in A/B testing?

Statistical significance means the difference between two test variations is unlikely to be due to chance — it's a real, measurable improvement. In CRO, we typically aim for 95% statistical significance, meaning we're 95% confident the result is real. Reaching statistical significance requires sufficient traffic and time. Running a test too short or with too little traffic can lead to false positives (thinking a change works when it doesn't).

How much does CRO cost?

CRO costs vary based on the scope of work, number of tests, and complexity of your website. At Prebo Digital, we offer tiered packages (Starter, Medium, Expert) tailored to your needs and budget. We recommend starting with a discovery call to understand your conversion goals, current performance, and testing roadmap. We'll provide a custom quote based on the scope of work required.

How to Recognise a Scam

Be cautious of job offers that ask for upfront payment, promise unrealistic returns, or lack verifiable company information. Legitimate agencies like Prebo Digital will never ask for payment before delivering work. Always verify company details, check reviews on independent platforms, and ask for references from existing clients before engaging any marketing agency.

How to Protect Yourself

Protect yourself by researching the agency thoroughly, checking their certifications and partnerships, reading client testimonials, and requesting a detailed proposal before committing. Ask for case studies and references. Legitimate agencies will be transparent about their process, pricing, and expected outcomes. Never share sensitive business data until you've verified the agency's credibility.
