Wikipedia language editions — SEO authority reference.

Methodology — where these numbers come from

DR is Ahrefs Domain Rating; DA is Moz Domain Authority. Both are third-party estimates of backlink authority on a logarithmic 0-100 scale, drawn from each tool's public reference data — neither is a Google metric, and both drift as link indexes update. Figures shown are rounded approximations, last verified 2026-06.

Every language edition lives on a subdomain of wikipedia.org, so link equity and trust consolidate at the root domain — which is why per-edition scores cluster at the very top of the scale. A reference in a mid-size edition carries most of the parent domain's weight. That mechanic is the basis of Wikipedia backlink campaigns, and it is why Simple English Wikipedia ranks #2 here despite a far smaller reader base.
