Google launched the Hummingbird algorithm update in August 2013 to make search results more conversational. The update allows Google to provide direct answers to questions searched by users. While Hummingbird impacted 90% of searches, the effects were usually small and SEO was largely unaffected. However, long tail keyword opportunities emerged as a result. The Hummingbird update strengthened the importance of original, relevant content that provides useful information to users.
