A mirror site is basically a copy of an original website, set up to give users the same content and features. They help improve speed and access by spreading traffic across different servers, making it easier for people in various locations to load pages quickly. Plus, they act as backups if the main site goes down. However, it’s important to manage them well for SEO; otherwise, search engines might penalise you for having duplicate content. Using things like canonical tags can help make sure your main site stays on top in search results.
