Our free Google PageRank and Domain Authority Checker analyses your website's SEO authority metrics — including Moz DA, Page Authority, Spam Score, and Trust Flow — to help you understand your site's standing in Google's ranking algorithm and plan your link-building strategy effectively.
What is Google PageRank?
Google PageRank was the original algorithm developed by Google founders Larry Page and Sergey Brin at Stanford University. It assigned a score from 0–10 to every webpage based on the quantity and quality of backlinks it received. Google officially deprecated the public PageRank toolbar in 2016, but PageRank as an internal ranking signal continues to power Google's search algorithm.
Today, third-party metrics like Moz Domain Authority (DA), Ahrefs Domain Rating (DR), and Majestic Trust Flow have become the industry standard proxies for measuring a website's link-based authority. Our tool analyses these modern authority metrics to give you a comprehensive picture of your website's SEO strength.
What Metrics Does Our Checker Analyse?
- Domain Authority (DA): A Moz metric scored 1–100 predicting how likely a domain is to rank on Google. Higher DA = more ranking power. DA is calculated using linking root domains, total backlinks, and MozRank.
- Page Authority (PA): Predicts the ranking potential of a specific page rather than the whole domain.
- Spam Score: Indicates the percentage of sites with similar link patterns that have been penalised by Google. A score above 30% warrants a backlink audit.
- Total Backlinks: Total number of inbound links pointing to the domain or page.
- Linking Domains: Number of unique referring domains — a more important metric than raw backlink count.
- Trust Flow: A Majestic metric measuring the quality of backlinks. Links from trusted, authoritative sites increase Trust Flow.
What is a Good Domain Authority Score?
- DA 1–20: New or low-authority site. Focus on building quality backlinks and original content.
- DA 21–40: Growing site with some authority. Continue consistent link building and SEO.
- DA 41–60: Established site with moderate authority. Competitive in most niches.
- DA 61–80: High authority site. Strong competitor in most industries.
- DA 81–100: Mega-authority sites like Wikipedia, Google, Amazon. Near-impossible to reach organically.

Frequently Asked Questions
Is Google PageRank still used? +
Yes, internally. Google removed the public PageRank toolbar in 2016, but PageRank as a concept continues to be a core part of Google's internal ranking algorithm. Third-party metrics like Moz DA and Ahrefs DR are now used by SEO professionals as proxies.
What is Domain Authority and who created it? +
Domain Authority (DA) is a metric created by Moz that predicts a website's ability to rank on search engines on a 1–100 logarithmic scale. It is calculated using dozens of factors including linking root domains and number of total links.
How often does Domain Authority update? +
Moz updates DA scores roughly every month when it re-crawls the web and refreshes its link index. Significant changes to your backlink profile may take 4–6 weeks to be reflected in your DA score.
Can I increase my DA quickly? +
DA improvements take time and consistent effort. Focus on earning high-quality backlinks from authoritative sites, creating valuable content, and fixing technical SEO issues. Significant DA improvements typically take 3–12 months.
What is a Spam Score? +
Spam Score is a Moz metric indicating the percentage of sites with similar characteristics that have been penalised or banned by Google. A score of 1–30% is low, 31–60% is medium, and 61–100% is high risk and warrants a backlink audit.
