What are DA and PA? A Complete Guide to Domain & Page Authority
Ever feel like your website’s content is great, but it’s still not ranking well on Google? The issue might be your website’s Domain Authority (DA) and Page Authority (PA). These SEO metrics help you understand how strong your website and individual pages are in the eyes of search engines.
In this guide, we will break down what DA and PA are, how they work, and how you can check them to improve your SEO performance.
What is Domain Authority (DA)?
Understanding Domain Authority
Domain Authority (DA) is a score that predicts how well a website will rank on search engine results pages (SERPs). Developed by Moz, the DA score ranges from 0 to 100. A higher DA score indicates a better chance of ranking well in search results.
Factors Influencing Domain Authority
- Quality of Backlinks – Links from trusted, high-authority websites improve your score.
- Number of Root Domains – More websites linking to your domain increase your DA.
- Content Quality – High-quality, original content boosts credibility.
- Technical SEO – Proper website structure, mobile optimization, and fast loading speeds.
- Domain Age – Older domains generally have a higher DA.
Real-World Example:
Imagine you run a popular blog about Indian recipes. If other high-authority food blogs and websites link to your content, your DA will improve, making your website more likely to rank for keywords like “best biryani recipes.”
What is Page Authority (PA)?
Understanding Page Authority
Page Authority (PA) measures the ranking strength of a specific page, rather than the entire website. Also developed by Moz, it uses a similar scale from 0 to 100. Higher PA scores mean better chances of ranking high for specific keywords.
Factors Influencing Page Authority
- On-Page Optimization – Keyword usage, meta tags, and internal linking.
- Backlink Quality and Quantity – External links pointing directly to the page.
- Content Relevance and Quality – Original, valuable, and well-organized content.
- User Experience (UX) – Mobile-friendliness, fast loading speeds, and ease of navigation.
Real-World Example:
Suppose you have an article titled “What is Marketing? Understanding the 7Ps and 4Cs of Marketing.” If it receives backlinks from other marketing websites, its PA will increase, making it more likely to rank high for related search terms.
