Why conversion rate matters for website development
Every second of load time and every extra field in a form costs you customers.
A 1-second delay in page load can reduce conversions by 7%. IRPR builds websites with Next.js for sub-second load times and server-side rendering. We also implement lazy loading and CDN delivery.
Our conversion rate website development services include A/B testing infrastructure from week one. We deploy Optimizely or Google Optimize so you can test headlines, CTAs, and layouts continuously. Our 98% on-time delivery ensures you launch when planned.
Generic agency vs. conversion-focused development
Most agencies build pretty sites. We build sites that sell.
Generic web agencies focus on design elements like colors and fonts, not on user behavior. They often skip A/B testing, use slow page builders, and deliver code you cannot easily modify. Their pricing is hourly, so costs balloon when you ask for changes.
IRPR treats conversion rate as a feature. We use React and Next.js for fast rendering, implement heatmaps (Hotjar), and set up split testing. We deliver with a fixed price and a documented CI/CD pipeline on GitHub Actions. You own the source code and can iterate immediately.

Our 4-phase process for conversion rate website development
We follow a repeatable system from concept to release.
Phase 1: Discovery. We audit your current site, review analytics, and identify friction points. We deliver a conversion hypothesis document within 1 week.
Phase 2: Design. We create wireframes and high-fidelity prototypes focused on user flow. We A/B test two design variants before coding begins.
