Astro is new and specialized in building static sites, making it ideal for a blog. Static sites are ones like blogs where the user does not have to log in or have a custom feed generated (like they would on Twitter, for example). Because everybody sees the same page and feed, the pages can be optimized and cached globally on servers close to the visitor (known as the edge). This means your blog gets served up at lightning speed, providing a fantastic user experience. As is typically the case, here, great user experience also brings great search engine optimization (SEO), meaning you can expect your site will rank higher in search engines.
