Hummingbird Affects and Matt Cutts Observations.
Matt Cutts said that the Hummingbird standard actually results 90% of all queries but at the same time he said this is only to a little outcome. So while Panda may have affected 10% or so and Penguin nearer to 3% or so, Hummingbird affected 90%. But Matt Cutts said only to a little level where customers should not observe.
Matt Cutts observations;
I know Search engines have informed us visitors and SEOs should not have observed any effect to positions and visitors depending on this criteria upgrade. But we alleged it may have affected some.
