What the symptom of "Humming bird" Effect your Website?

I want to know about what the symptom of “Humming bird” Effect your Website?

We’ve had lots of discussions already about Hummingbird, so why not start by having a look at those first?

In a nutshell, Hummingbird is about improving the recognition and understanding of natural language, so that Google can understand people’s questions better. This is the first Google update in a while that really gets into the quality of your writing.

Thanks for useful information.
