Domain Authority (DA) predicts how well a website might rank on search engines. The Domain Authority Checker calculates a numeric score based on link profiles and other factors, helping you gauge a domain’s competitive strength. High DA sites typically have extensive, quality backlinks and consistent SEO practices, while lower DA indicates room for improvement. This tool allows marketers to benchmark their domain against competitors, plan link-building strategies, and track growth over time. Although DA isn’t an official Google metric, it’s still widely used for quick estimates of site credibility and potential search performance.
