The overwhelming majority of people at risk for suicide broadcast many warning signs. Often, they are subtle, but more often, they represent a loud cry for help for an ultimately preventable situation.

Very few people commit suicide on a whim.

I'd bet my life's savings that enough suicidal people search for the word "suicide" that this showed up in metrics.

Having worked at Google, I could take a guess at how these help numbers came to be a feature. Some search engineers were probably analyzing a question along the lines of "What pattern of searches result in unhappy users that don't come back?"
