Blackbook optimises what happens after the click: flows, landing pages, forms and checkout, so more visitors become customers. Data-driven, tested and designed – not guessed. ## Conversion is design, not tricks ### Conversion optimization of flows, forms and checkout Dark patterns can lift a number for a quarter and cost you trust for three. We work the other way: remove the friction, answer the doubt before it arises, and make the next step obvious. Conversion is rarely about a bigger button – it is about a journey without gaps. We start in the data: where people drop off, what they hesitate over, and what it costs. From there we build hypotheses and test them – on real users, not in the meeting room. ## Measure, test, learn One test doesn't prove much; a system of them does. We set up the measurement, prioritise the experiments by impact and turn the results into decisions – so optimisation becomes a rhythm, not a project. **What we deliver:** Funnel and drop-off analysis · Hypotheses & A/B testing · Landing page optimization · Checkout and form flows · Microcopy · Goal setup & reporting ## From campaign to checkout We optimise across the whole chain – campaign sites that need to capture leads, webshops that need to sell, and onboarding flows that need to retain. Same method, wherever the conversion happens. Is your traffic getting the finish it deserves? [Let's talk about your conversion](https://www.blackbook.dk/en/contact/). ## Selected cases Conversion across the chain: webshops, campaigns, insurance sales and onboarding flows where design and data together shortened the path to action. ### Responsive eCommerce web design — Eye Copenhagen - Responsive e-commerce site for Eye Copenhagen with retailer directory and webshop – SEO-optimised platform that became the hub for all company activities.
