User Privacy
Ahead of Google updating their privacy policy Google has directed a large portion of their ad budget toward ads about how they protect users online.
What better way to ensure user privacy than to allow them to register their accounts under psydonyms? The real name policy on Google+ was part of what made Google want to stop providing referrer data for logged in users who search on Google. This has had a knock on effect where other social sites are framing everything, requiring registration to read more of public user generated content & sending outbound traffic through redirects.
Google's new privacy policy allows them to blend your user data from one service into refining the experience (and ads) on another:
If you’re signed into Google, we can do things like suggest search queries – or tailor your search results – based on the interests you’ve expressed in Google+, Gmail, and YouTube. We’ll better understand which version of Pink or Jaguar you’re searching for and get you those results faster.
Google & Facebook's war (against) user privacy is catching media and governmental attention. Microsoft highlighted some of Google's issues in their "putting people first" ad campaign & the blowback has caused Google not only to publish PR-spin "get the facts" styled blog posts, but to launch yet another ad campaign.
