Frequently Asked Questions
Domain Rating (DR) is an Ahrefs metric that shows the strength of a website's backlink profile on a scale from 0 to 100. Higher DR indicates a stronger backlink profile, which generally correlates with better search engine rankings. DR is calculated based on the quantity and quality of external backlinks pointing to a website.
Semrush DA is the Semrush Authority Score for the same domain, shown next to Ahrefs DR so you can compare authority signals across both SEO providers.
Ahrefs Rank is a global ranking of websites by their backlink profile strength. A lower number indicates a stronger website - rank #1 is the strongest website in the Ahrefs database. This metric helps you understand how a domain compares to all other websites globally.
Referring domains are unique websites that link to a target domain. Having backlinks from many different referring domains is generally more valuable for SEO than having many backlinks from the same domain. This metric shows the diversity of a website's backlink profile.
Organic traffic is the estimated monthly search traffic a website receives from organic (non-paid) search results. This metric helps you understand how much search visibility a domain has and how well it ranks for various keywords.
This tool uses the Ahrefs API for DR, rank, backlinks, referring domains, and organic metrics, and the Semrush API for Authority Score. Data is cached to keep repeat checks fast.
You can check up to 20 domains at once. Simply enter domain names separated by newlines, commas, or spaces. The tool will automatically clean and deduplicate the domains before checking.
Domain Rating is a strong indicator of a website's ability to rank in search engines. Websites with higher DR tend to rank better because they have established authority through quality backlinks. When building links or analyzing competitors, DR helps you prioritize high-authority targets.
Backlinks are the total number of links pointing to a domain, while referring domains count unique websites linking to it. For example, if Site A links to you 100 times, that's 100 backlinks but only 1 referring domain. Search engines generally value diversity (more referring domains) over quantity (more backlinks from the same source).
