Why conversion rate matters in web development
A 1% increase in conversion rate can double your revenue if you have high traffic.
Generic web development agencies build websites that look good but don't sell. An experienced conversion rate website development agency like IRPR builds with conversion data from day one. We use tools like Google Optimize and VWO to run A/B tests on design variants before launch.
Statistically, 68% of B2B companies track conversion rate as a top KPI. Yet most websites have a conversion rate below 2.35%. IRPR targets 5-10% for lead gen sites and 3-5% for ecommerce product pages by using proven patterns like social proof bars, countdown timers, and one-click checkout.
Generic agency vs. experienced conversion rate agency
Most agencies deliver code. IRPR delivers conversion lift.
A generic website development shop builds pages based on a design mockup. They don't track bounce rates, click heatmaps, or form abandonment. They ship code and walk away.
IRPR builds every page with conversion in mind. We set up analytics before writing a single line of code. We test CTAs, colors, and copy variants during development. After launch, we monitor and iterate.
- Builds from Figma mockups with no data
- No A/B testing or analytics setup
- Delivers code without conversion goals
- Charges hourly for every change
- No post-launch optimization
- Average conversion rate below 2%
- Designs from user behavior data
- A/B tests variants during build
- Sets up Google Analytics 4 and heatmaps by default
- Fixed pricing, no hourly surprises
- Monitors conversion post-launch for 30 days
- Tracks at 5-10% conversion rate
How we build for conversion
A 4-phase process that starts with your data and ends with a measurable lift.
Phase 1: Data audit. We review your existing analytics, heatmaps, and session recordings. We identify drop-off points in your funnel. Phase 2: Hypothesis and design. We write testable hypotheses and design 3 variants of key pages. Phase 3: Build and test. Senior engineers code the winning variant with React, Next.js, and Tailwind. Every page includes Optimizely snippet for future tests.
Phase 4: Launch and iterate. We deploy to production on Vercel or AWS, set up real-time dashboards in Metabase, and run the first A/B test within 48 hours of launch. You see data before we leave.
