DA Checker

Its free DA Checker reports Moz Domain Authority (DA), Ahrefs Domain Rating (DR) and Majestic Trust Flow (TF) together, giving users three independent perspectives on a domain’s link authority. The site also offers a backlink checker that shows who links to a website, including DR for each link, and a Semrush Authority Score checker.

For larger lists, users can access bulk tools for metrics including DA, Page Authority, Spam Score, DR, TF and Semrush Authority Score. Free visitors can run daily checks without an account, with additional checks available after signing in. Paid plans support bulk checks of up to 100 URLs at once for DA, DR and TF, with results available for export as CSV files or report screenshots. The platform also provides SEO utilities designed to help clean outreach lists, many of which run in the browser. dachecker.io explains how to interpret authority scores and cautions that they are third-party metrics, not Google ranking factors.
