[01] AI-Powered Performance Marketing

Turn the traffic you already have into revenue.

Most websites convert only 1–3% of visitors. The other 97–99% leave without buying anything. You get a CRO process that finds out exactly why they’re leaving — and fixes it, so the traffic you’re already paying for earns more.

What's included

Every layer of your funnel, optimised for conversion.

See exactly where you're losing customers — CRO audit

Heatmap analysis, session recording review, funnel drop-off mapping and user research give you a full diagnosis of what's stopping visitors from converting, before you spend a penny fixing it.

Only ship changes that actually work — A/B & multivariate testing

Structured experiments on headlines, CTAs, layouts and offers run to statistical significance, so you only implement proven winners, never a guess.

Turn the clicks you're already paying for into customers — landing page optimisation

Conversion-focused design and copy for paid ad destinations, lead gen pages, product pages and checkout flows means less of your traffic goes to waste.

See exactly where visitors lose confidence — UX & heatmap analysis

Hotjar and Microsoft Clarity analysis, scroll depth tracking and rage-click identification show you the precise moment people give up, so you fix the right thing first.

Stop losing revenue at checkout — funnel & checkout optimisation

Cart abandonment analysis, checkout friction removal and post-purchase flow optimisation recover the revenue that's currently slipping away in the final steps.

Trust your numbers before you act on them — analytics & tracking setup

GA4 event tracking, goal configuration, enhanced ecommerce setup and attribution modelling make sure every decision is based on what's really happening, not guesswork.

FAQ

Questions before you start.

You get more customers from the traffic you're already paying for, without raising ad spend. A CRO agency does that by analysing your website and funnel to find conversion bottlenecks, then running structured A/B tests to fix them.
Initial insights from audits and heatmaps appear within 2–4 weeks. Meaningful A/B test results typically take 4–8 weeks depending on traffic volume. CRO is a compounding process — results build over time.
Most clients see 15–40% conversion rate improvement over the first 6 months of structured CRO. Results vary significantly based on how much low-hanging fruit exists in your current funnel.
One monthly retainer or a fixed project price, agreed up front — no hourly meters, no percentage-of-uplift surprises. Because CRO works on traffic you already have, there's no extra ad budget to fund. Your free growth plan includes the exact figure.
You need enough traffic to reach statistical significance in tests — typically 1,000+ monthly conversions per variation. For lower-traffic sites, we focus on qualitative methods (heatmaps, user testing) alongside quantitative testing.
One thing: the retainer (or the agreed project price). We run the research, the tests and the reporting. Your only job is to handle the extra sales your existing traffic starts producing.
