How do I ensure performance remains stable after optimization?

Performance regressions frequently arise from new content, plugin updates or changes to third-party scripts. To maintain stability, we recommend three measures: automated monitoring that continuously measures Core Web Vitals and alerts on degradations, a performance budget definition that sets maximum page sizes and script volumes, and regular performance reviews on a quarterly basis. This way, regressions are detected within hours and can be addressed before they negatively affect field data.
