Next steps
Having completed a site audit, you should have accurate review data in a form that makes it easy for developers and other stakeholders to prioritize and justify changes.
Prework
Before gathering performance metrics for a site audit, there are several checks you can do to identify easy fixes and areas for focus. Some of these checks are relatively subjective, but can identify problems that affect perceived performance.
Check site security
You won't be able to build a PWA without HTTPS. Serving your site over HTTPS is fundamental for security, and many APIs won't work without it. If you need to justify implementation costs, find out why HTTPS matters.
Share the results
Once you've audited a site, make sure to package the results in a digestible form. Be sensitive to the people on the receiving end of your audit, structure your report carefully and present your data in terms of opportunities and solutions.
Use tools to measure performance
