How to Check Domain Authority (DA), Page Authority (PA), and Spam Score for Free
If you’re into SEO, content marketing, or just curious about how trustworthy a website is, understanding metrics like Domain Authority (DA), Page Authority (PA), and Spam Score can be extremely useful. These indicators help evaluate a website’s strength, credibility, and risk profile — making them essential when planning backlinks, guest posts, or digital partnerships. The good news? You don’t need to spend a rupee to check them.
Understanding the Importance of These Metrics
Domain Authority and Page Authority, developed by Moz, are predictive scores that estimate how well a website or a specific page is likely to rank on search engines. DA reflects the strength of the entire domain, while PA focuses on the ranking potential of a single page. Spam Score, on the other hand, indicates the likelihood of a site being penalized or flagged as low-quality based on certain backlink patterns. These three combined give a clearer picture of a site’s SEO health.
Where You Can Check DA, PA, and Spam Score for Free
You don’t have to purchase expensive SEO tools to access these metrics. Moz itself offers a free tool called Link Explorer where you can check DA, PA, and Spam Score by simply entering a URL. There are also browser extensions like MozBar that let you view these details while you browse the web. Other platforms like Small SEO Tools and Prepostseo also provide similar services without charging, though they may have usage limits.
Why These Scores Matter in SEO Strategy
When choosing websites for backlinks or guest posting, checking these scores helps you avoid risky domains and prioritize high-authority ones. A high DA suggests strong influence and trust, while a low Spam Score indicates safer link-building potential. Together, these insights allow marketers and site owners to make smarter decisions that enhance visibility and protect their rankings from Google penalties.
