Google recently announced a new set of ranking signals that are going to be combined with existing signals they use to measure user experience. There are three new signals that will be added to become one new combined ranking signal called Page Experience.
Since COVID-19 has affected many organizations and businesses, Google and Bing have developed methods that can be used to let them know if your organization has any special announcement that relates to COVID-19. However, please note that all of their guidance has been provided rapidly, and is still undergoing changes. Therefore, additional changes and updates may be required, and the new functionality may encounter bugs.
