A video blog, or vlog, is a platform that uses videos rather than text or images to share content. Vlogs allow bloggers to freely share their opinions and reactions through facial expressions and body language visible in videos. While podcasts are audio-only files distributed via RSS, vlogs involve uploading video files to blogs. When designing a video blogging website, considerations include providing a richer experience through short videos versus long posts, attracting a bigger audience through engaging video content, and using video for effective marketing and promotion of products or services.
