A few months ago, we introduced a search feature that displays the toll-free U.S. poison control number when you search for related information. This got us thinking about other ways we can help people get clear information from Google search in times of crisis or distress. So we recently launched a feature that displays the National Suicide Prevention Lifeline at the top of the results page for certain search queries in the U.S. We hope this quick access to information helps people in emotional distress who may benefit from calling a suicide prevention hotline.
