Yes, on the marketplace screen you will see a column category labeled "LRD". This is "Linking Root Domains".  That number in that colum on the domain is the number of linking domains.  If the box color is yellow then it is the Majestic number of LRDs and if it is blue, then it is the Ahrefs number. 

We use the most complete indexation source for your more accurate knowledge.
