Why conversion rate matters in development
A fast site is useless if visitors don't do what you want. We build for action, not just aesthetics.
Conversion rate optimization starts in the code. We structure HTML, CSS, and JavaScript for load speed below 2 seconds. We set up A/B testing on day one, not as an afterthought. Every button, form, and image is a conversion asset.
IRPR has delivered over 200 projects with measurable conversion improvements. Clients see an average 25% increase in conversion within 90 days of launch. We track from day one so you know exactly what works.
The difference between building a site and building a converter
Most developers code features. We code conversion paths.
Generic web development shops focus on delivering a template on time. They don't measure whether the site actually works. We do. Every sprint ends with a conversion check, not just a feature checklist.
IRPR's process is built around CRO. We design for the metric that matters. We test before launch, not after. And we hand over a system that keeps improving.
- Builds then optimizes later
- No A/B testing setup
- Hourly billing with unknowns
- Generic performance tweaks
- No conversion funnel tracking
- Handoff without analytics
- Conversion-first design from day one
- A/B testing infrastructure built in
- Fixed price from Roadmap phase
- Performance optimization for conversion
- Real-time funnel analytics with GA4 and Hotjar
- Full ownership — source code and data
Our conversion-focused development process
Four phases, each with a measurable deliverable. No guesswork.
We start with a 2-week Roadmap phase where we define your conversion goals, identify key metrics, and produce a fixed-price quote. No surprises. Then we move into design and development with weekly demos and A/B test results.
Every phase ends with a review based on data, not opinion. You see the conversion impact before we move to the next step. Post-launch, we hand over the experimentation framework so your team can keep testing.

Why teams hire us.
Conversion engineering, not just web development
Every engineer at IRPR has experience running A/B tests and optimizing for conversion. We don't just build features; we build experiments. Your site ships with a built-in optimization loop.
Fixed price from Roadmap phase
You get a fixed quote after the 2-week Roadmap. No hourly billing, no scope creep. Average projects cost between $80K and $250K with no surprises.
Full ownership of code and data
When we finish, you own everything: source code, analytics accounts, A/B test results, and domain. We never lock you in. Our contract makes that explicit.
Senior engineers only, no junior team members
Every project is staffed with engineers who have 7+ years of experience. We don't outsource or assign junior devs. You talk directly to the people writing code.
Transparent process with weekly demos
You see working software every Tuesday. We show real conversion data, A/B test results, and performance metrics. No status reports, just demos.
Post-launch iteration support
We train your team to run A/B tests. We hand over the experimentation framework and documentation. If you need us for additional tests, we offer retainer support at $5K/month.
