The main difference between a blog and a vlog lies in the content delivery format. A blog typically consists of written text, images, and occasionally videos, presented in a chronological format on a website or platform. On the other hand, a vlog, short for a video blog, primarily delivers content through video. Creators record themselves sharing thoughts, experiences, or expertise. While blogs rely on written content, vlogs use video content to engage the audience, offering a more dynamic and visual experience.
