The main difference between a blog and a Google Web Story lies in format and user experience. Blogs are text-based articles that provide in-depth information, often with images and links. They are typically designed for reading and can be longer in form.
On the other hand, Google Web Stories are visual, mobile-first, and swipeable content that resemble the "stories" format used on social media platforms. Web Stories focus on short, engaging snippets of information, with images, video, and animations designed to quickly capture attention. While blogs are great for detailed content, Web Stories offer a more dynamic, interactive experience.
