.gov TLD audit hub
United States federal-government TLD — restricted to US government entities.
The .gov TLD is administered by the United States Cybersecurity and Infrastructure Security Agency (CISA) and is strictly restricted to US federal, state, local, tribal and territorial government entities. Registration requires authorization from a senior elected or appointed official and is free of charge as of 2021. CISA has progressively raised security baselines for the namespace: HTTPS preload was made mandatory, DMARC enforcement is required, and there is a published technical-baseline standard that all .gov sites must meet. There are roughly 6,500 active registrations. SEO treats .gov as an authority signal — many search ranking systems and link-graph algorithms apply elevated trust scores to .gov domains, which is why backlinks from .gov sites are highly sought after. Email deliverability is excellent because the namespace enforces strong authentication. We pay particular attention to JSON-LD structured data and accessibility (Section 508 / WCAG 2.1) compliance when auditing .gov sites — both are mandatory under federal law.
