Check Domain Authority (DA), Page Authority (PA), and Spam Score for any website. Get instant SEO metrics powered by Moz API.
In the ever-evolving world of search engine optimization (SEO), understanding key metrics like Domain Authority (DA) and Page Authority (PA) is crucial for any digital marketer, SEO professional, or website owner. These metrics, developed by Moz, have become industry standards for evaluating the potential ranking strength of websites and individual pages. This comprehensive guide will help you understand what these metrics mean, how they impact your SEO strategy, and how to use our free DA PA checker tool to analyze and improve your website's performance.
Domain Authority is a search engine ranking score developed by Moz that predicts how well a website will rank on search engine result pages (SERPs). The DA score ranges from 1 to 100, with higher scores indicating a greater ability to rank. This metric is calculated using multiple factors, including the number of linking root domains, the quality of those links, and the overall link profile of the domain.
Think of Domain Authority as a predictor of your website's potential to rank. It's not a direct ranking factor used by Google, but rather a comparative metric that helps you understand how your domain stacks up against competitors. A domain with a DA of 50 is likely to rank better than a domain with a DA of 20, all other factors being equal.
Key Insight: Domain Authority is calculated on a logarithmic scale, meaning it's easier to move from DA 20 to DA 30 than from DA 70 to DA 80. This logarithmic nature reflects the competitive landscape of SEO, where gaining authority becomes increasingly difficult as you reach higher scores.
Several factors influence your Domain Authority score:

Page Authority is similar to Domain Authority but focuses on individual pages rather than entire domains. Like DA, PA scores range from 1 to 100, with higher scores indicating better ranking potential. Page Authority predicts how well a specific page will rank in search results based on its link profile and other SEO factors.
While Domain Authority gives you an overall picture of your website's strength, Page Authority helps you identify which specific pages have the best potential to rank. This is particularly useful for content marketing strategies, as it helps you prioritize which pages to optimize and promote.
Factors that influence Page Authority include:
Pro Tip: A page can have a higher PA than the domain's DA if it has received significant external links or has been heavily promoted. This is common for viral content or highly-linked resource pages.

Spam Score is a metric developed by Moz that flags domains that may be penalized or banned by Google. The score ranges from 0 to 17, with lower scores being better. A score of 0-1 is considered ideal, while scores above 5 may indicate potential issues that could negatively impact your SEO performance.
Spam Score is calculated based on 17 different factors that are commonly associated with spammy or low-quality websites. These factors include:
Monitoring your Spam Score is crucial because high scores can indicate that your domain is at risk of being penalized by search engines. If you notice your Spam Score increasing, it's important to audit your backlink profile and remove or disavow low-quality links.

Moz Rank is another important metric that measures the popularity of a page based on the number and quality of links pointing to it. The score ranges from 0 to 10, with 10 being the highest possible score. Moz Rank is calculated logarithmically, meaning it's much harder to move from MR 8 to MR 9 than from MR 2 to MR 3.
While Domain Authority and Page Authority are predictive metrics, Moz Rank is a more direct measure of link popularity. A high Moz Rank indicates that a page has received significant attention in the form of quality backlinks. This metric is particularly useful for:
There are several misconceptions about Domain Authority and Page Authority that can lead to poor SEO decisions:
This is false. DA and PA are predictive metrics developed by Moz, not ranking factors used by Google. However, the factors that influence DA and PA (like quality backlinks) are indeed ranking factors, which is why these metrics correlate with search rankings.
While higher DA generally correlates with better rankings, it's not a guarantee. A page with lower DA can outrank a higher DA page if it has better content, more relevant keywords, and better user engagement metrics.
You cannot directly buy Domain Authority. However, you can invest in legitimate SEO services that build quality backlinks, which will naturally improve your DA over time. Be wary of services promising instant DA increases, as these often involve black-hat techniques that can harm your site.
DA scores are recalculated regularly by Moz, and your score can change even if you haven't made any changes to your site. This is because DA is a comparative metric - if other domains improve faster than yours, your relative DA may decrease even if your actual link profile improved.
