The specific optimization techniques depend on what region the user is in and on how the developer wrote and served that particular page. When Chrome optimizes an HTTPS page, only the URL is shared with Google; other information – cookies, login information, and personalized page content – is not shared with Google. </span></span></div> <b style="font-weight: normal;"><span style="font-family: inherit;"><br /></span></b> <br /> <div dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"> <span style="font-family: inherit;"><span style="background-color: transparent; color: black; font-size: 11pt; font-style: normal; font-variant: normal; font-weight: 400; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">These optimizations are only applied when the loading experience would be painful to users.
