Website Performance Optimization

An act, process, or methodology of making something (as a design, system, or decision) as fully perfect, functional, or effective as possible.

To serve websites faster, ensure uptime, improve usability, reduce data transfer, lessen server load, and enhance user satisfaction.

We should optimize for what the user is looking for, where they came from, what they want to know, and our goal for the user.
