Overview
Users are mistrustful of or confused by pages that automatically request their location on page load. Rather than automatically requesting a user's location on page load, tie the request to a user's gesture, such as a tapping a "Find Stores Near Me" button. Make sure that the gesture clearly and explicitly expresses the need for the user's location.
Recommendations
Under URLs, Lighthouse reports the line and column numbers where your code is requesting the user's location. Remove these calls, and tie the requests to user gestures instead.
See Ask permission responsibly for a list of best practices when requesting a user's location.
More information
If geolocation permission was already granted to a page before Lighthouse's audit, Lighthouse cannot determine if the page requests the user's location on page load. Reset the permissions and run Lighthouse again. See Change website permissions for more help.
Lighthouse collects the JavaScript that was executed on page load. If this
code contains calls to geolocation.getCurrentPosition() or
geolocation.watchPosition(), and geolocation permission was not already
granted, then the user's location was requested.
