How Nordstrom Ensures its Website Will Perform at 100% This Holiday Season

Brugalette offered the following best practices around monitoring site performance for retailers to implement before the holiday rush:

1. Test early, test often. "And be prepared for huge spikes in traffic when you're testing," Brugalette said.

2. Focus on planning. Even this close to the holidays, "plan it out so that you test the right things," Brugalette said. "And if your testing cycles are short or not as extensive as you hoped, test what's most important."
