What is the best use for NEW DOMAIN EXTENSIONS? I have built a website around "####.online" and have now purchased many more domains with new extensions. Examples = "####.taxi", "####.services", "####.tours", "####.community", "####.restaurant", "####.villas", "####.business", "####.cafe", "####.energy", "####.solar", "####.cruises", "####.events", "####.fish", "####.news", etc etc etc...I have several more.
The "####" is a specific place, a touristic destination.
What is the best way to bring these domains together in a whitelist approach in order to improve ranking around searches related to "####"???
