Conversion Rate Optimization Agency

Biotik is a design-led conversion rate optimization agency. We help SaaS, fintech and e-commerce teams get more from the traffic they already have — turning visits into sign-ups, sign-ups into active users, and active users into revenue.

Most CRO stops at button colours and headline swaps. We start with the product. The biggest wins usually hide in the flows, the friction and the moments of doubt — so we fix those, back the changes with research and experimentation, and measure what actually moves.

What we optimise

We focus on the parts of the funnel where small percentage gains compound into real money — and where design has the most leverage.

• Landing pages and pricing — clarity, message match and trust
• Sign-up and onboarding — time-to-value and activation
• Checkout and upgrade flows — friction and drop-off
• Retention and re-engagement touchpoints

How we work

CRO is a loop, not a one-off. We combine your analytics with qualitative research to see where and why people leave, prioritise the highest-leverage opportunities, then design and test changes — keeping what wins and learning from what doesn’t.

• Research — analytics, session review and user insight to locate the leaks
• Hypotheses — prioritised by expected impact and effort
• Design & build — production-ready variants, not throwaway mockups
• Test & learn — measure the lift, ship the winners, repeat

Not sure where the leaks are yet? A focused UX audit is the fastest way to find them and gives us the map to prioritise against.

When to hire a CRO agency

If acquisition is healthy but the funnel leaks, optimisation beats buying more traffic every time. It’s also the right move before a redesign or a pricing change — so decisions are driven by evidence, not opinion. Deeper interface work then flows into hands-on UX/UI design, and if you want the underlying framework we use, our guide to CRO for European SaaS lays it out.

What we measure — and what we ignore

A conversion rate on its own is a vanity number. We tie every test to a metric that maps to your business, and we watch guardrails so a “win” at the top doesn’t quietly cost you further down the funnel.

• Primary metric — signups, activations, qualified trials or revenue per visitor, depending on the stage
• Guardrail metrics — refunds, churn, support load and lifetime value, so a short-term lift isn’t a long-term loss
• Segment splits — new vs returning, device, channel and plan, because an average hides the story

We resist the two most common traps: peeking at a test and stopping the moment it looks good, and celebrating a top-of-funnel bump that never reaches the bank. A result only counts when it holds to a pre-set sample size and survives the guardrails.

CRO for SaaS, fintech and e-commerce

The loop is the same; the leverage points differ. In SaaS, most of the money is in signup-to-activation and the pricing page. In fintech, trust and compliance-friendly flows decide whether people finish onboarding at all. In e-commerce, it’s product pages, cart and checkout — where a single removed field can move revenue. We bring the pattern library from each, and adapt it to your funnel rather than pasting a generic checklist.

Conversion rate optimization — common questions

What is conversion rate optimization?

Conversion rate optimization (CRO) is the practice of increasing the share of visitors who take a defined action — sign up, subscribe, buy — using research and controlled experiments to decide what to change. It’s a method, not a bag of tricks: you change something because a funnel, a session replay and a valid test agreed, not because a blog post said so.

What does a conversion rate optimization agency do?

A CRO agency helps you get more from the traffic you already have. It combines analytics and user research to find where people drop off, forms hypotheses about why, then designs and tests changes — measuring the impact on conversion, activation and revenue.

How does conversion rate optimization work?

It runs as a loop: measure where users drop off, understand why through qualitative research, form a prioritised hypothesis, ship the change as a controlled A/B test, then keep what wins and learn from what doesn’t. Repeat, and small gains compound against every future visit.

Why is conversion rate optimization important?

Because it compounds. Unlike buying more traffic, a conversion win applies to every visit that follows — so improving the rate is usually cheaper and more durable than increasing the volume. It also turns design and product decisions into measurable revenue.

How is Biotik’s approach to CRO different?

Biotik is design-led. Rather than only tweaking buttons and copy, we treat conversion as a product and UX problem — fixing the flows, clarity and friction that drive most of the gains — backed by research and experimentation.

Who is CRO for?

CRO suits SaaS, fintech and e-commerce teams with meaningful traffic that isn’t converting, activating or upgrading as well as it should. It’s the highest-leverage work when acquisition is healthy but the funnel leaks.
