Alexa may refer to any of the following:
1. Alexa is the default wake up word for the Amazon Echo digital assistant.
2. Alexa is an Amazon.com company that was originally founded in April 1996. It uses information collected from users who have the Alexa browser toolbar installed to build a more intelligent Internet and traffic ratings. Alexa is a great method to determine general statistics for your web page and blog and one of the best ways to compare your site with your online competition.
