Paste up to 10 domains or URLs below and click "Check Authority" to instantly see Domain Authority (DA) and Page Authority (PA) scores powered by Moz.
What Is a DA PA Checker?
A DA PA Checker is a free SEO tool that lets you instantly measure the Domain Authority (DA) and Page Authority (PA) of any website or webpage. These scores — developed by Moz — predict how likely a site is to rank on Google and other search engines.
Whether you're doing competitor research, evaluating backlink prospects, or auditing your own site, checking DA and PA is one of the first steps in any solid SEO workflow.
What Do DA and PA Mean?
Domain Authority (DA) is a score from 0 to 100 that measures the overall strength and credibility of an entire domain. It's calculated using over 40 signals, with backlink quality and quantity being the most influential.
Page Authority (PA) works the same way, but applies to a single page rather than the whole domain. A blog post, product page, or landing page each has its own PA score.
| Score Range | What It Means |
|---|---|
| 0 – 20 | New or low-authority site |
| 21 – 50 | Growing authority |
| 51 – 80 | Strong and competitive |
| 81 – 100 | Top-tier domain |
Important: DA and PA are relative metrics — they're most useful when comparing sites against each other, not as absolute benchmarks.

Why DA and PA Matter for SEO
1. Evaluate Link Building Opportunities
Before reaching out for a guest post or backlink, check the DA of the target site. A link from a DA 60+ site carries far more value than one from a DA 10 site.
2. Competitive Analysis
Compare your domain's authority against direct competitors. If your DA is significantly lower, you know where to focus your link-building efforts.
3. Track Your SEO Growth
Use the bulk checker regularly to monitor how your DA improves over time as you build more quality backlinks and publish authoritative content.
4. Qualify Backlink Profiles
When auditing your existing backlinks, use DA PA scores to identify low-quality or spammy domains that might be dragging down your authority.
How to Improve Your Domain Authority
DA doesn't improve overnight, but these practices consistently move the needle:
- Earn high-quality backlinks from relevant, authoritative sites in your niche
- Remove or disavow toxic backlinks that harm your domain's reputation
- Publish in-depth, linkable content — guides, tools, and data-driven posts attract natural links
- Fix technical SEO issues — ensure fast load times, clean site architecture, and proper internal linking
- Be consistent — DA builds gradually; regular content and outreach compound over time
