What is PLS by browser auto-translate
PLS by browser auto-translate compares Perceived Load Speed (PLS) between users who experienced browser-based automatic translation and those who didn’t. This lens helps you identify whether automatic translation affects how fast your website feels to load.
PLS is a user-centric performance metric created by Uxify that measures when users perceive the page as visually complete. It’s especially useful in scenarios where multiple elements must be visible for the page to feel ready — which can be influenced by localization.
Healthy PLS by browser auto-translate sample
Should you worry
A healthy PLS by browser auto-translate lens shows minimal difference between the two segments — translated and non-translated. As long as both remain within the green zone (fast perceived speed), user experience is consistent regardless of translation status.
Unhealthy PLS by browser auto-translate sample
When users with auto-translate enabled experience noticeably higher PLS, it suggests that the translated version of the page takes longer to feel ready. This can lead to lower engagement from non-native language users.
