Adwords and to a lesser degree Analytics appears to be slowing down. I've also wondered if the data levels are getting massive and the systems need to have some next level discovery/overhaul. More generally it's amazing how good Google search is. You really feel it when you try the alternates with the exception of long tail searches. I find these days if I do longer search strings Google gets a bit lost, more so than in the past. This being a small % of searches makes it a limited issue. I think the next search engine revolution will happen when someone does to Siri/Cortana what Google did for text search. Something that can do more than show information and be more a PA that can complete tasks.
