How strong is a typical top .gov website?
The median Link Authority of the top 50 .gov websites is 64, and the median site among them has 74,382 linking domains. Across the 14 domain endings MrKeyword lists, that median runs from 48 (.in) to 67 (.org), and .gov is 2nd of 14. Link Authority is MrKeyword's 0–100 score on a logarithmic scale, so a few points near the top stand for a large difference in links.
How does .gov compare with other domain endings?
Of the 14 domain endings MrKeyword lists, .gov has the 13th most domains in the web graph's top 2 million, with 4,249. The table compares each ending's count, its most-linked website and the median Link Authority of its top 50.

How was this list made?
The list takes every registered domain ending in .gov among the top 2 million positions of MrKeyword's web graph (August–October 2026), orders them by linking domains and keeps the first 100 that are websites rather than infrastructure. .gov is a restricted ending for United States government bodies. No infrastructure domain such as a CDN, script host or link shortener was in that range, so none was left out.
Each Link Authority follows the same rule as MrKeyword's site profiles and its checker: MrKeyword's own PageRank where it has seen enough links to a site, otherwise the site's web graph position on a 0–100 log curve (how Link Authority is calculated). Linking domains count each linking website once. Web graph rank is the site's PageRank position, which weighs where links come from, so it does not always follow the linking-domain order. Ranks describe links between domains, not traffic. How MrKeyword collects and labels this data.
