Free DA & PA Checker Without Registration
Understand a domain before planning your next SEO step. Compare up to 3 domains per check using authority metrics, spam indicators, domain age, and server IP.
Domain Authority (DA) and Page Authority (PA) are Moz metrics for comparing the ranking potential of domains and pages. Use them alongside content relevance and backlink quality. They are not official Google scores or a guarantee of search rankings.
Moz Spam Score indicates the percentage of sites with similar characteristics that Moz found had been penalized or banned by Google. A high score suggests reviewing content and backlinks more closely. It does not prove that the domain you are checking has been penalized.
Server IP information helps identify domains that share an IP address. Matching addresses are highlighted in gold in the table. Shared hosting or a CDN can explain matching IPs, so a shared address alone does not establish common ownership.
You can check up to 3 domains at a time without creating an account, subject to the daily quota. Your remaining quota appears above the input field. To check more than 3 domains at once, choose a Premium package with the capacity you need.
BulkMetrik Rating (BMR) is a combined score of 0–100 developed by BulkMetrik. It uses DR, DA, and PA, then applies deductions and score caps based on Spam Score. Results also appear as 0–5 stars. The free checker and dashboard use the same formula.
Ahrefs Domain Rating (DR) measures the relative strength of a domain’s backlink profile on a scale of 0–100. Moz Domain Authority (DA) uses a different method and dataset. The same domain can have different DR and DA scores. Use both as comparison tools in your SEO research.
Domain age is calculated from the registration date available through RDAP or WHOIS to today. That date may change if a domain was deleted and registered again. Domain age does not indicate the age of its content or how long a website has been active.
Results depend on provider availability and update schedules. BulkMetrik may show stored results that are still valid, so recent changes may not appear immediately. A — means data is unavailable, not zero. BMR is not shown when DR data is unavailable.
BulkMetrik combines Ahrefs DR, Moz DA, PA, and Spam Score, RDAP or WHOIS registration records, and IP information from DNS. BulkMetrik calculates BMR from the available metrics. Use these results to guide your research, then review content relevance and backlink quality before making a decision.
