domain authority vs page authority: What's the Difference?
Explore the key differences between domain authority and page authority, two critical metrics in SEO that can significantly impact your website's performance.
What is Domain Authority?
Domain Authority (DA) is a search engine ranking score developed by Moz that predicts how well a website will rank on search engine result pages (SERPs). DA scores range from 1 to 100, with higher scores indicating a greater ability to rank. This metric considers various factors, including the number of linking root domains, the total number of links, and other elements, to determine the overall strength and credibility of the entire domain.
What is Page Authority?
Page Authority (PA), also developed by Moz, measures the predictive ranking strength of a single web page on a search engine result page. Like Domain Authority, Page Authority scores also range from 1 to 100. PA focuses primarily on the scoring of the individual page based on factors such as the number of links pointing to that specific page, the quality of those links, and social signals.
How does Domain Authority work?
Domain Authority works by analyzing the link profile of a website as a whole. It takes into account the quantity and quality of inbound and outbound links, the age of the domain, and overall site content quality. Moz’s algorithm evaluates these factors and generates a score which helps determine the likelihood of the domain ranking well across various keywords.
How does Page Authority work?
Page Authority evaluates the backlink profile of a specific page rather than the entire domain. It assesses the strength of the page by considering linking domains, the content quality, and various on-page SEO factors. The algorithm uses machine learning to predict the likelihood of a single page ranking on SERPs for specific queries.
Why is Domain Authority Important?
Domain Authority is important because it provides a broad overview of a website’s overall SEO strength. A higher DA score can boost the site’s credibility, potentially leading to higher rankings on search engines. Marketers and SEO professionals often use DA as a benchmark for their efforts compared to competitors, identifying areas for improvement in link-building and content marketing strategies.
Why is Page Authority Important?
Page Authority is crucial for understanding how well an individual page may perform in search results. A higher PA score increases the chances of a specific page being discovered and clicked on, which is vital for targeted campaigns and driving traffic to specific content. By focusing on improving PA, SEO experts can optimize their high-value pages to capitalize on search trends effectively.
