How We Increased Website Conversion Rates by 23.1% Using Data

The Challenge

Junction Design is a UX/UI agency that creates beautiful, functional websites for their clients. They're good at what they do—but they faced a frustrating problem that many agencies encounter.

One of their clients was experiencing poor conversion rates on their website. Visitors were coming, but they weren't becoming leads. The agency knew the design could be improved to fix the problem, but the client was hesitant to invest in changes.

Why? Because recommendations based on "best practices" or "what usually works" aren't convincing when a client is being asked to spend money on redesign.

The client wanted proof. They wanted data. They wanted to know:

  • Where exactly are visitors dropping off?
  • Why aren't people converting?
  • Which design changes will actually make a difference?
  • What ROI can we expect from this investment?

Without concrete evidence, the project was stalled.

Junction Design needed someone to provide the data-backed insights that would convince their client to move forward—and ensure the redesign actually worked.

Our Approach

We conducted a comprehensive Conversion Rate Optimization (CRO) audit, using data to identify exactly where the website was losing potential customers.

CRO Audit Using Multiple Tools We used a combination of:

  • Google Analytics: To track user flow, identify drop-off points, and understand behavior patterns
  • Microsoft Clarity: To watch actual session recordings and see exactly how users interacted with the site

This wasn't guesswork. We watched real users navigate the site, saw where they got confused, and identified the exact moments they decided to leave.

User Behavior Analysis We analyzed:

  • Which pages had the highest bounce rates
  • Where users spent time vs. where they quickly left
  • Which CTAs were being clicked and which were ignored
  • Form abandonment—where users started filling out forms but gave up
  • Mobile vs. desktop behavior differences

Conversion Funnel Analysis We mapped the entire customer journey:

  • Entry points (how visitors arrived)
  • Path through the site
  • Drop-off points (where they left)
  • Successful conversion paths (what worked)

Friction Point Identification Using heatmaps, scroll maps, and session recordings, we identified specific friction areas:

  • Confusing navigation
  • CTAs that weren't visible or compelling
  • Forms that were too long or asking for too much information
  • Slow-loading sections causing abandonment
  • Mobile usability issues
  • Trust signals that were missing

Data-Backed Design Recommendations For each problem we found, we provided:

  • Evidence (screenshots, data, session recordings)
  • Impact assessment (how much this was costing in lost conversions)
  • Specific design solution
  • Expected improvement

We didn't just say "the CTA should be bigger"—we showed exactly where users were looking, why they weren't clicking, and what would make them take action.

Supporting the Agency's Proposal We packaged all findings into a clear, visual presentation that Junction Design could use with their client. The data told an undeniable story: these specific issues are costing you this many conversions, and these changes will fix it.

The Results

🎯 +23.1% increase in conversion rate after implementing our recommendations

But here's what else happened:

The client approved the redesign immediately after seeing the data

Junction Design had confidence in exactly what to change and why

No wasted effort on design changes that wouldn't move the needle

Measurable ROI from the design investment—the client could see the direct impact

Stronger agency-client relationship built on evidence, not opinions

The 23.1% improvement meant significantly more leads flowing to the client's business every single month. For a B2B service company, even a handful of additional quality leads can mean hundreds of thousands in additional revenue.

What We Learned

Design decisions backed by data aren't just more convincing—they're more effective. When you know exactly where users are struggling, you can fix the real problems instead of making changes based on assumptions.

Clients don't resist change—they resist uncertainty. Give them data showing what's broken and how to fix it, and they'll invest confidently.

For agencies, having a data partner transforms the conversation from "trust us, this will work" to "here's exactly what's broken, here's the evidence, here's the solution, and here's the expected outcome."

Session recordings are gold. Watching real users interact with a site reveals issues that analytics alone never would. You see the confusion, the hesitation, the frustration—and that tells you exactly what needs to change.
