The document discusses the difference between a blog and a conventional website. While there is no technical difference, blogs are generally set up as online journals or diaries consisting of posts in date order that can be clicked to view fully. Their purpose is often to provide information or promote a viewpoint, unlike conventional websites that mainly aim to sell products. Blogs can contain a large amount of original content and be considered an authority, ranking highly on search engines and attracting more traffic if monetized through sales or advertising. In summary, blogs differ from websites in their layout as online journals and in purposefully providing information rather than immediate sales.
