How we drive conversion through development
Every code change is tied to a specific conversion metric.
We start by auditing your current site with Google Analytics, Hotjar heatmaps, and user session recordings. We identify the top 3 friction points that are costing you sales, then build solutions in a 2-week sprint cycle.
Our team writes custom JavaScript and CSS to eliminate load time, fix broken checkout logic, and simplify forms. Each deployment is A/B tested against the current version. We only keep changes that statistically improve conversion.
The difference between generic web development and conversion-focused development
Most agencies build websites that look good. IRPR builds websites that convert visitors into customers.
A generic development shop focuses on delivering features on time, often ignoring the business outcome. They use hourly billing, open-ended timelines, and rarely test whether a feature actually improves conversion.
IRPR approaches every project with a conversion hypothesis. We wireframe, prototype, and deploy with built-in analytics hooks. Our fixed-price model includes 2 weeks of post-launch optimization based on real user data.

Our 4-phase conversion development process
From idea to live, every phase is designed to maximize conversion.
We follow a structured process that combines lean development with CRO best practices. Each phase ends with a deliverable you can review and approve.
The roadmap phase alone takes 1 week and produces a fully costed plan with wireframes and a testing strategy.
