Theory is useful. Real results are better.

In this case study, we walk through exactly how our team took an underperforming eCommerce store, identified the problems holding it back, redesigned the experience from the ground up, and delivered a 119% improvement in conversion rate within 90 days of launch.

No fluff. No generic advice. Just a clear, step-by-step account of what we did, why we did it, and what the numbers looked like on the other side.

011. The Client: NovaNest Home

NovaNest Home is a mid-sized online retailer selling premium home decor and lifestyle products across the United States and Canada. They had been in business for four years and had built a loyal customer base through Instagram and word of mouth.

Despite steady traffic — averaging 38,000 monthly sessions — their revenue had plateaued. Their conversion rate sat at 3.1%, below the industry average. They came to us with one clear goal: more sales from the traffic they already had.

022. The Problems We Found

Before writing a single line of code or designing a single screen, we conducted a full conversion audit. We analyzed session recordings, heatmaps, funnel drop-off data, and exit surveys.

Slow & Bloated

6.4s mobile load time with unoptimized images and heavy scripts.

Weak Product Pages

Single images and buried CTAs caused visitors to bounce rapidly.

Leaky Checkout

79% abandonment rate due to forced account creation and 6-step flow.

No Trust Infrastructure

Reviews and security badges were entirely missing from the site.

044. What We Built — And Why

Phase 1: Performance Overhaul

We started here because a beautiful product page means nothing if it takes 6 seconds to load.

  • Compressed all images to WebP (71% size drop)
  • Implemented lazy loading for all assets
  • Deployed global Edge CDN
  • Removed legacy duplication scripts

Result: Mobile load time dropped to 2.1s

Phase 2: Product Pages

We rebuilt the entire template to focus on buyer confidence and friction removal, following product page best practices for maximum engagement.

6. Key Lessons Learned

Speed is the Foundation

Nothing else matters if your website is too slow to use. Fix performance first.

Trust Must Be Visible

Review count and policies must be shown where the purchase journey happens.

Friction Kills Silently

Customers rarely say why they left. Audit your checkout and navigation for every step.

Measurable Growth

Abandoned cart sequences alone generated 11% of total monthly revenue.
