Auditing Code + Removing Inefficiencies = Increased Performance & Conversions
Walmart wanted to modernize their website to improve user experience and increase revenue. They had committed to a redesigned website with React, expecting the change to increase traffic substantially. Unfortunately, the extensive update yielded a traffic increase of just 1-4%, indicating that their load speeds hadn’t improved as much as they had expected. Walmart knew there was room for improvement, so they called in Formidable to get to the bottom of what was slowing things down. Formidable needed to dig into the details to increase the speed of the Walmart Checkout system and improve conversion rates.
Formidable began the process by auditing the existing Checkout app to understand inefficiencies and performance bottlenecks. During the two week audit, Formidable found a critical mass of legacy code that needed to be pared down to improve load times.
After presenting findings and suggesting improvements, Formidable was able to reduce the code bundle from 1.1MB to 617KB in the course of one week.
From there, Formidable continued to work with the Walmart team to improve and optimize code, choosing updates strategically to prioritize payoff vs effort calculations.
Working collaboratively gave us a chance to train the Walmart team on best practices, enabling them to improve other portions of their website once our work was done.
Formidable was able to reduce the Walmart Checkout bundle of code by nearly 50% and add application runtime optimizations, which led to a huge improvement in speed and performance. Formidable also successfully trained the Walmart team on React best practices.
