About Domain Authority & Page Rank
What is Page Rank?
Page Rank is a metric (0-10 scale) that measures the authority and trustworthiness of a domain based on its backlink profile and overall web presence. Originally developed by Google, it's now provided by OpenPageRank as an alternative to proprietary metrics.
Page Rank Score Interpretation
- 9-10: Extremely authoritative domains (Google, YouTube, Facebook)
- 7-8: Very strong authority, major publications and platforms
- 5-6: Good authority, established websites
- 3-4: Moderate authority, growing websites
- 0-2: Low authority, new or small websites

Frequently Asked Questions
What's the difference between Page Rank and Domain Authority?
Page Rank (0-10 scale) and Moz's Domain Authority (0-100 scale) both measure domain strength and authority. Page Rank is based on Google's original algorithm, while DA is a proprietary metric by Moz. Both use backlink profiles as primary factors.
How often should I check my domain authority?
Check monthly or quarterly to track long-term trends. Domain authority changes slowly, so daily checking isn't necessary. Focus on consistent SEO efforts rather than score fluctuations.
Is a higher Page Rank guaranteed to rank better?
Not guaranteed. While higher authority correlates with better rankings, Google uses 200+ ranking factors including content quality, user experience, technical SEO, and relevance. Authority is just one piece of the puzzle.
Can I check authority for subdomains?
Yes! Enter the full subdomain (e.g., blog.example.com) to check its specific authority. Subdomains may have different authority scores than the main domain.
Why do some domains show no data?
Very new domains, private/local domains, or domains with no backlinks may not have Page Rank data available. The API requires a minimum web presence to generate scores.
