“1. Start a campaign pushing google to change the order of the search results. However, what really would be the point of this? How many people type actually regularly “Three Black Teenagers” into Google? Barely anyone!

“2. Instead start sharing, searching and making more positive stories about black teenagers. If there were more stories of black teenagers doing well or positive news they would be higher up in the search results.”

A Google spokesperson said: "Our image search results are a reflection of content from across the web, including the frequency with which types of images appear and the way they’re described online. This means that sometimes unpleasant portrayals of sensitive subject matter online can affect what image search results appear for a given query. These results don’t reflect Google’s own opinions or beliefs - as a company, we strongly value a diversity of perspectives, ideas and cultures."

In April this year a tweet by Twitter user @BonKamona drew attention to the Google Image search results she found when looking up "unprofessional hairstyles for work" and "professional hairstyles for work."
