The number of inbound links for sites supported by dot brand domains is low, and most of domains have no inbound links. As a matter of comparison, highly optimised brand websites would have in excess of 1,000 inbound links. The right part of the chart correspond to above 100 inbound links, and the darker colours correspond to the more recent researches. It is very interesting to note that the number of domains with inbound links is growing, while the proportion of domains with no links is decreasing.
Matt Cutts explains in this video that even though “he wouldn’t assume that just because you have a large number of indexed pages that you automatically get a high-ranking”, the more pages you have, the more chances you have to rank for different keywords. Plus, the more pages you have, the more likely you have more overall links and PageRank, which do directly impact your rankings.
The number of large sites in the dotBrand world is increasing consistently since 2016.
