What is a Bulk DA PA Checker and How Does It Work?
A bulk DA PA checker queries Moz's machine-learning index across up to 25 domains simultaneously, calculating Domain Authority (DA), Page Authority (PA), and Spam Score in a single report.
Unlike single URL lookups that require tedious manual entry, bulk processing allows link builders, domain investors, and SEO agencies to evaluate outreach prospect lists in seconds, filtering out toxic link networks before spending budget on outreach campaigns.
Domain Authority (DA)
Logarithmic 0–100 scale predicting how well an entire root domain will rank across search engine result pages.
Page Authority (PA)
Evaluates the specific ranking potential of an individual URL or landing page based on internal and external links.
Spam Score
Percentage (1%–100%) indicating the probability that a website displays patterns seen on Google-penalized or banned sites.
