Since 4Q2011, clients’ site analytics have shown an increasing number of Google organic searches with “(not provided)” listed as the referring keyword. The cause is Google’s use of SSL (encrypted) search for personalized results. Let’s talk about the meaning, impact and future of this change.
What is SSL search?
In October 2011, Google announced that it was automatically redirecting signed-in users to the https version of the Google search site. All search traffic sent through this URL will be encrypted via SSL as it leaves the searcher’s browser and goes through their router to their ISP, Google and then on to Google’s recommended websites. The primary reason is to protect the privacy of users’ searches if they are conducted via unsecure WiFi or public networks. I would offer two other possible reasons for this move: i) limiting liability; and ii) enhance the value proposition of PPC.
Limiting liability – organizations in both the US and EU have challenged Google’s privacy policies, particularly data sharing and user protection elements. While I’m not a lawyer, I can imagine Google’s liability would be significantly reduced if they encrypt search data for signed in users – users who have, further, agreed to terms of service that can dictate additional protections for Google. Is this speculation? Absolutely… but, for Google, winning at this level means focusing on lawsuits and fighting patent disputes, not brand development through feel-good open data policies.
Value proposition of PPC – if we view websites participating in Google’s AdWords & AdSense networks as legally-contracted extensions of Google, we could hypothesize that this could provide the legal protection needed to allow Google to continue to offer keyword level data to participants. Happily for Google, this also enhances the value proposition of participation in those PPC networks, as it will become the best way to get keyword level data. (Google Webmaster Central still shows the search terms people used to reach your site over the past 30 days but it is not as integrated as PPC data is or would be.)
