I wonder if this header information which makes Google+ so "secure" may be a factor in SERP placement. That is, whether or not you have that level of security determines placement. I don't know. That's just an off-the-cuff thought. ;)

Great insight. Is this another possible "look behind the curtain" on SERP?
