Fraggles are an indication of Googles potential ability to index information at a level that is more detailed and nuanced than just a page or a URL. This is important for the potential of Google indexing Single Page Apps (SPAs), Progressive Web Apps (PWAs) and JavaScript in general. It may also feed into the idea of Entity-First-Indexing, if concepts on a page can be broken out and organized around different concepts or entities in Google’s index.
