Hey all,
I gave this stuff a little time to jell. I've made 2 orders which covered 4 keyword/urls on 2 domains.
Obvious success was on a medium - slightly hard competition,well paying CPC term. The domain is already fairly strong - and the page had prior links - but I did nothing new. It moved from 2 to 1 - where it had been stuck before. IMO - that alone was worth it.
The hard term where I was really stuck at #3 - didn't budge - but again it didn't go down either - so it's all good. This term takes effort just to keep it at #3 because it has slid down a few notches before.
The medium competition keyword on a weaker domain didn't move in Google, though Yahoo/Bing moved it up to 2 or 3 - but for some reason, Google hates this domain - though Yahoo/Bing Love it. Yeah, I've read a bunch of stuff about that - and checked my GA but still don't really get it. It's an older domain too....just a dog in Google right now for mysterious reasons.
Anyway, I am satisfied that this was good for some extra link diversity and a nudge - which is what I thought it would do.
