Conversion Rate Metrics That Matter
We measure what matters: conversion rate, bounce rate, average session duration, and form completion rate.
Every project starts with a 2-week audit of your current funnel. We analyze heatmaps, session recordings, and Google Analytics data to identify drop-off points. Based on that, we define specific KPI targets for the new build.
After launch, we continue tracking. Typical results include a 35-50% lift in conversion rate within the first 60 days. For one ecommerce client, we increased their checkout completion rate from 60% to 85% using a simplified multi-step flow.
IRPR vs Generic Dev Shops
Not all agencies build for conversions. Here is how IRPR differs from a generic development shop.
Generic shops build the design you give them and move on. They do not test variants or optimize for conversion. You pay hourly and end up with a site that looks good but does not sell.
IRPR treats every pixel as a conversion lever. We wire up A/B testing from day one, run heatmaps, and use session replays to validate user behavior. Your price is fixed, your code is yours, and we optimize for results.
- Hourly billing with scope creep
- No A/B testing infrastructure
- Design based on opinion, not data
- Hands off after launch
- Unoptimized page speed
- No conversion funnel tracking
- Fixed price from the start
- A/B testing baked into the build
- Data-driven design decisions
- Post-launch CRO support available
- Built with Next.js for fast load times
- Real-time funnel analytics dashboards
Our Conversion-First Build Process
We build in four phases, each focused on measurable conversion improvements.
Phase 1 is a 2-week audit and strategy session. We analyze your current analytics, run heatmaps, and define a hypotheses list for what will increase conversion.
Phase 2 is UX design and wireframing based on data. Phase 3 is development with built-in experiment hooks. Phase 4 is launch and a 30-day optimization sprint.
What Ships with Every High Conversion Website
Every project includes a set of conversion-focused deliverables. You get full ownership and ongoing visibility.
We do not just hand over a website. You get the complete development and optimization toolkit needed to measure and improve conversion over time.
All source code, analytics dashboards, and A/B test configurations are yours. You can continue running experiments or extend the site with your own team.
