“We made the new platform 60% faster and this resulted
in a 14% increase in donation conversions.”
For every 1 second of improvement Walmart experienced up to
a 2% increase in conversions. For every 100 ms of improvement, Walmart grew incremental revenue by up to 1%
Staples shaved 1 second off median, 6s off 98th percentile,
conversions improved 10%
“Over time we found a strong correlation between site speed
and buyer purchases per week”
“A slow site impacts the brand” Tammy Everts
