01 · Challenge

An authority site, weighed down by its own success.

KPMG Australia's knowledge-heavy website had become a victim of years of continuous publishing. Oversized media, legacy scripts and a sprawling navigation meant mobile visitors were waiting more than three seconds for content to render — and bouncing before they ever reached an insight.

The brand authority was intact. The page-speed economics were not. Each second of delay was shaving conversions off the high-intent journey to "Contact Us", and Core Web Vitals were quietly throttling the rankings of pages KPMG had invested years building.

02 · Approach

A full-stack performance and UX overhaul, built to last.

We treated KPMG's site like an enterprise product, not a brochure: every template audited, every asset weighed, every script questioned. The goal was simple — render fast, navigate faster, and keep it that way long after we left.

Four parallel workstreams stripped the weight out of the front-end and stood up the governance KPMG needed to protect the wins post-launch.

The performance playbook
4 workstreams · 1 metric

Code and asset slimming

Audited every template, stripped unused libraries, inlined critical CSS and deferred non-essential JavaScript so the first paint landed under a second.

Next-gen hosting and caching

Migrated to an auto-scaling cloud platform with global edge delivery, Brotli compression and layered caching rules — near-instant time-to-first-byte across regions.

Experience-first navigation

Re-architected the menu, merged redundant sections and added contextual breadcrumbs to shorten the path from landing page to the right insight.

Real-time speed governance

Built a CMS performance bar that warns authors when a page risks exceeding size or speed thresholds — protecting the gains without developer intervention.

03 · The result

Sub-2-second pages, and a 19% lift in how users engage.

Within 90 days the average page load fell to 1.7 seconds, down from 2.9 — a 26% improvement in the sitewide page-speed score. Mobile visitors now reach KPMG's insights before they would have bounced under the old build.

User engagement climbed 19% on the back of a leaner layout and simplified navigation, with a measurable uplift in completed journeys to "Contact Us" as readers reached the CTAs faster.
