Lesson 5: Quality, Performance, SEO, and Deployment (DevOps Basics)

Up to now, you’ve focused on building websites that work and look good. In this lesson, you shift from building to delivering. A site is only truly “done” when it can be released with confidence, loads quickly on real devices and networks, is easy to find on search engines, and stays reliable as you update it over time.

You will learn practical ways to improve quality and reduce risk before release by using version control workflows that support teamwork, and testing strategies that catch issues early. You’ll also focus on performance and SEO essentials that directly impact user experience and discoverability — especially on mobile.

Finally, you will connect your work to real production environments through hosting, deployment pipelines, and CI/CD basics. By the end of the lesson, you should be able to take a website from “works on my machine” to a production-ready release, and deliver project work (including a CMS-based site and a PWA) in a way that matches real-world expectations.
