What are DA and PA in SEO?

DA (Domain Authority) and PA (Page Authority) are SEO ranking metric scores developed by Moz that predict how likely a website or specific webpage is to rank in search engines (ranging from 1 to 100).

How is the Spam Score calculated?

The Spam Score represents the percentage of websites with similar features that have been penalized or banned by Google, indicating potential link profile risks.

How does this tool calculate DA PA client-side?

The checker uses an advanced authority estimation algorithm. It queries Google's DNS servers for real-time domain age, evaluates TLD extension trust (e.g. .edu is higher), assesses domain name length, and scans for negative spam metrics.

Can I check multiple domains in bulk?

Yes, absolutely. You can enter or paste up to 10 domains at once to analyze and compare authority profiles in a dynamic grid.

Frequently Asked Questions

What is a good Domain Authority (DA) score? +

DA is a logarithmic scale. Scores between 1 and 20 are common for fresh websites. 20 to 50 represents average authority (most small businesses). 50 to 80 is very good (popular blogs, large stores), and 80+ is excellent (Wikipedia, Google).

How do I increase my Domain Authority? +

Focus on building high-quality editorial backlinks from trusted, high-authority domains, writing outstanding unique content, removing broken links, and maintaining a clean spam-free link profile.

Why do `.edu` and `.gov` extensions have higher base trust? +

Academic institution and government websites are strictly regulated and rarely engage in spam linking. Search engines naturally view these extensions as highly authoritative, boosting their domain coefficients.

Does Google use Moz DA for search rankings? +

No. Google does not officially use Moz Domain Authority in its ranking algorithms. Google uses PageRank and hundreds of other proprietary signals, but DA serves as a highly accurate industry proxy.
