Australian e-commerce redesigns that skip the conversion audit produce beautiful stores with the same conversion problems as the old one

A conversion audit for an e-commerce store uses four primary data sources: heatmap and scroll depth data from a tool like Hotjar or Microsoft Clarity to identify where on-page engagement drops, session recordings filtered to checkout abandonment to identify the specific step where buyers leave, GA4 checkout funnel data to quantify drop-off at each step, and mobile PageSpeed Insights to identify performance barriers that are not visible in the heatmap data. The audit should run for a minimum of two to four weeks on a store with sufficient traffic to produce statistically meaningful heatmap and recording data. For stores with lower traffic, the audit period may need to be longer. The output is a prioritised list of conversion barriers that becomes the specification for the redesign brief, not a starting point for aesthetic discussion.

Core Web Vitals improvement requires three things written into the redesign scope before development begins: a performance budget that specifies maximum image sizes, maximum number of third-party scripts, and target LCP and INP values; a requirement that the development team measures Core Web Vitals on the staging environment before launch and provides a pre-launch Lighthouse report; and a contractual deliverable that the store meets the defined targets at launch. Without these three elements, redesigns routinely add larger images, more animations, and additional marketing scripts that collectively reduce mobile performance below the pre-redesign baseline. LCP under 2.5 seconds and INP under 200 milliseconds on mobile are the targets that determine Google's assessment of page experience, and they affect both Google Shopping quality scores and organic ranking signals.

A conversion-focused Australian e-commerce redesign brief should specify: the placement and format of the delivery estimate on the product page (not just in the FAQ or checkout confirmation email), the exact position of Afterpay and Zip badges relative to the price and add-to-cart button, the trust signal elements in the checkout flow (security badge, return policy link, accepted payment icons), the number of steps in the checkout and whether guest checkout is the default, the mobile layout requirements at each breakpoint, the review integration requirements including structured data for Google Shopping star ratings, and the Core Web Vitals targets as measurable deliverables. A brief that specifies these elements produces a redesign that can be evaluated against objective criteria at launch. A brief that specifies colours, fonts, and "feel" produces a redesign that can only be evaluated aesthetically.

Trustpilot widget migration during a redesign requires three explicit steps in the development scope: the Trustpilot Business Unit ID and widget configuration must be reproduced in the new theme rather than copied from the old theme's HTML; Google structured data markup for AggregateRating must be implemented on product pages and tested using Google's Rich Results Test before launch; and the product review feed, if the store uses individual product reviews rather than site-level reviews, must be relinked to the new product page template. Stores that launch a redesign and then discover that their Trustpilot widget is not rendering correctly, or that their Google Shopping product listings no longer show star ratings, typically take three to six months to recover the structured data signal because Google needs to recrawl and reindex the pages before the ratings reappear in Shopping results.

A full e-commerce redesign for an Australian brand, including a two-week conversion audit, a one-week brief, five weeks of design and development, and one week of QA and launch preparation, runs to approximately ten weeks from project start to launch. Redesigns that scope in a post-launch A/B test add a further four to eight weeks of monitoring before the old design is retired. The most common cause of delays beyond the ten-week timeline is photography — when new product images are not ready at the design handoff date, the launch is delayed because the design cannot be correctly evaluated or QA'd with placeholder imagery. Including a photography brief and a firm image supply deadline in the project brief from the start is the most effective way to hold the ten-week timeline.
