A blog is a piece of written content that is published on a web page or site. The main purpose of blogs is to convey information in a way that is more informal or conversational than other long-form written content. Blog websites are updated with new information on an ongoing basis. They normally consist of a collection of posts. Posts may be short, informal, controversial, or more professional. While a traditional website page provides information for the visitor and encourages them to take a specific action, blog content provides the option for readers to comment and ask questions on individual posts. So blogs could be more engaging with visitors and customers than traditional websites.
