...today we announced [googleblog.blogspot.com...] that SSL Search on https://www.google.com will become the default experience for signed in users on Google.com. This change will be rolling out over the next few weeks. What is the impact of this change for webmasters? Today, a web site accessed through organic search results on http://www.google.com (non-SSL) can see both that the user came from google.com and their search query. (Technically speaking, the user’s browser passes this information via the HTTP referer field.) However, for organic search results on SSL search, a web site will only know that the user came from google.com.
