Auditing for Performance

Auditing for Performance

How do we help clients see where they can improve their site’s performance with incremental changes that they can work on over time? Susan will go through techniques she uses to test a site for performance and write up recommendations, including providing example code for the client to use in their own implementation. This talk will go over high-level ideas of performance and auditing a site, the tools you use, and how to communicate back recommendations to the client.
