Domain Score (DS) is a metric, developed by Ubersuggest, which ranges from 0 to 100. The higher the number, the more authoritative a domain is. This means that it will be hard to rank higher than that website with the same keyword.
It’s important to note that this metric is different from the Domain Authority (DA), used on Moz, and the Domain Rating (DR) from Ahrefs. It’s a sophisticated algorithm that determines how authoritative a domain is using different criteria, such as backlinks and social metrics. It came from Neil’s experience working in ranking his website and his clients all these years.
