Domain Authority (DA) vs. Page Authority (PA): What’s the Difference?
Share
Success is built on smart decisions—start here. If you're navigating the world of SEO, you've likely encountered the terms Domain Authority (DA) and Page Authority (PA). These metrics, developed by Moz, are pivotal in assessing a website's potential to rank on search engine results pages (SERPs). However, while they sound similar, they measure different aspects of your site's SEO performance. Understanding the distinction between DA and PA is crucial for crafting an effective SEO strategy.
In this blog post, we'll delve into the differences between Domain Authority and Page Authority, explore how they impact your SEO efforts, and provide actionable insights on how to improve both to enhance your site's visibility and ranking.
What is Domain Authority (DA)?
Domain Authority is a metric that predicts how well a website will rank on search engine result pages. Developed by Moz, DA is scored on a scale from 1 to 100, with higher scores indicating a greater ability to rank. It's calculated by evaluating multiple factors, including the number and quality of backlinks, the overall trustworthiness of the domain, and the site's age. DA provides a holistic view of your website's SEO strength.
What is Page Authority (PA)?
Page Authority, also developed by Moz, measures the predictive ranking strength of a single page on your website. Like DA, PA is scored on a scale from 1 to 100. It's determined by factors such as the number and quality of backlinks to that specific page, the page's content quality, and its internal linking structure. PA is particularly useful for assessing the SEO potential of individual pages, such as blog posts or product pages.
Key Differences Between DA and PA
- Scope: DA evaluates the overall strength of your entire domain, while PA assesses the ranking potential of individual pages.
- Calculation: Both metrics are calculated using machine learning algorithms that consider various factors like backlinks and content quality, but they focus on different scopes—DA on the domain level and PA on the page level.
- Purpose: DA is used to predict the ability of your entire site to rank, whereas PA helps in understanding how well a specific page might perform in search results.
Which Metric Should You Focus On?
Both DA and PA are important, but their relevance depends on your SEO goals. If you're aiming to improve your site's overall visibility and ranking, focusing on increasing your DA is beneficial. This involves strategies like building high-quality backlinks, enhancing site structure, and producing valuable content.
On the other hand, if you have specific pages that you want to rank higher, such as a key blog post or product page, boosting the PA of those pages should be your priority. This can be achieved by acquiring backlinks to those pages, optimizing on-page content, and ensuring a strong internal linking structure.
How to Improve DA and PA
Improving both DA and PA requires a comprehensive SEO strategy:
- Quality Content Creation: Regularly publish informative and engaging content that addresses your audience's needs.
- Backlink Acquisition: Earn backlinks from reputable websites to enhance your site's authority.
- On-Page Optimization: Ensure your pages are well-optimized with relevant keywords, meta tags, and user-friendly design.
- Internal Linking: Create a logical internal linking structure to distribute link equity across your site.
- Technical SEO: Improve site speed, mobile responsiveness, and fix any crawl errors to enhance user experience and search engine accessibility.

Understanding the difference between Domain Authority and Page Authority is essential for any effective SEO strategy. While DA gives you an overview of your site's potential to rank, PA allows you to focus on optimizing individual pages for better performance. By improving both metrics, you can enhance your site's visibility and ranking on search engines, driving more organic traffic and achieving your business goals.
