Quora is a website that gets used by millions of people for questions and answers. It works like most internet forums where someone asks a question on any topic and members of the public, sometimes professionals, will answer the question.
Advertisements show occasionally on the website and are usually tailored to the user. For example, if a user only views questions and answers for florists, then they will only get adverts based on flowers. This is amazing for advertising as it means that a business will be able to target their preferred demographic more precisely, thus resulting in a higher interaction rate.
