Blue Triangle retail customer traffic: 11/27 – 11/29

Many of the best deals started on Thanksgiving Day, and this year some retailers experienced issues with site availability and performance. Costco and Nordstrom Rack experienced outages Thanksgiving Day, and Target and BJ's slowed down. Black Friday was no different.

The top 500 eCommerce sites slowed 15% between Thanksgiving Day and Black Friday 2019. Costco's site continued to experience intermittent issues, and shoppers reported problems checking out on the Foot Locker site soon after they released the highly anticipated Yeezy Boost 350 V2 shoe. My colleague calls this phenomenon The Curse of Ye.

Methodology

This year we are focusing on two critical web performance metrics - Time to Interactive and Page Load Time. These metrics are highly correlated with buying behavior.

Time to Interactive
The amount of time it takes for the web page to become fully interactive. This is a Google Lighthouse metric, and is weighted heavily in Google's PageSpeed Score (v5) calculation.

Page Load Time
The amount of time required for the server to load the page completely, including content, images, JavaScript, CSS, and other external files.

Speed matters, especially on Black Friday. Below we see in Blue Triangle how conversion rate drops as users experience a slower and slower page load time.
