See the DA score (0-100) that reflects how authoritative your domain is in Google's eyes.
Total backlinks, referring domains, dofollow vs nofollow ratio, and link velocity trends.
Specific sites you should target for link building, ranked by difficulty and potential impact.
Our AI-powered checker provides estimates based on known data about each domain. For well-known domains, results are highly accurate. For newer or less-known sites, it provides a realistic range based on domain type and niche. The full Pro report pulls from a live crawl database.
Backlinks is the total count of all links pointing to your site — one domain can send hundreds of links. Referring domains is the count of unique domains sending those links. Referring domains is generally the more important metric, since 100 links from 100 different sites is far more valuable than 100 links from 1 site.
Domain Authority is a score from 0-100 that predicts how well a site will rank in search engines. Higher is better. New sites start at 1. Sites like Wikipedia and Google score 90+. For most businesses, getting to 30-50 DA is a realistic and meaningful goal.
Toxic links come from spammy, low-quality, or manipulative sites. Google's algorithm mostly ignores them now, but an unusually high concentration can trigger a manual penalty. Use the disavow tool in Google Search Console to address the worst offenders.
