XR (Extended Reality) SEO involves optimizing content and experiences for search within virtual reality (VR), augmented reality (AR), and mixed reality (MR) environments. This emerging field aims to ensure that XR content is easily discoverable and ranks well on search engines and within app stores or platforms specific to XR. Optimization strategies may include using relevant keywords in app descriptions and metadata, ensuring accessibility, and leveraging social media and traditional web content to drive traffic to XR experiences. As XR technology becomes more mainstream, understanding how to optimize for these digital spaces will be increasingly important for marketers and content creators.
