What is Domain Authority (DA) and Page Authority (PA)?
Domain Authority Explained
The 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. Think of DA as a website’s overall “reputation score” in Google’s eyes.
Key Points About DA:
- Created by Moz (not Google)
- Scale: 1-100 (higher is better)
- Updated monthly by Moz
- Based on multiple factors (40+ ranking signals)
- Comparative metric (relative to other sites)
- Predicts ranking potential, not guaranteed rankings
What Influences Domain Authority:
- Total number of backlinks – More quality links = higher DA
- Quality of linking domains – Links from high-DA sites matter more
- Diversity of link sources – Links from many different domains
- Link relevancy – Links from topically relevant sites
- Internal linking structure – How pages connect within your site
- Content quality and depth – Comprehensive, valuable content
- Social signals – Shares, engagement (indirect factor)
- Website age – Older established sites tend to have higher DA
- Technical SEO health – Site speed, mobile-friendliness, security
Important: Domain Authority is NOT a Google ranking factor. Google doesn’t use DA in its algorithm. However, DA correlates strongly with Google rankings because it measures many of the same factors Google considers.
Page Authority Explained
Page Authority (PA) is similar to Domain Authority but measures the ranking strength of individual pages rather than entire domains. PA also uses a 1-100 scale.
Key Differences: DA vs PA
- DA = Entire website or domain authority
- PA = Individual page/URL authority
- Homepage PA typically equals or is close to DA
- Internal pages usually have a lower PA than the homepage
- PA can vary widely across different pages on the same site
Example:
- Website DA: 45
- Homepage PA: 43
- Blog post PA: 28
- About page PA: 22
This shows that while the domain has decent authority (45), individual pages have varying authority levels based on their own backlinks and optimization.
How DA and PA Are Calculated
Moz uses a complex machine learning algorithm that considers:
1. Link Metrics (Most Important)
- Total number of linking root domains
- Quality and authority of linking domains
- Link relevancy and diversity
- MozRank (link popularity)
- MozTrust (link trustworthiness)
2. On-Page Factors
- Content quality and length
- Keyword optimization
- Internal linking structure
- User experience signals
3. Technical Factors
- Site speed and performance
- Mobile-friendliness
- SSL certificate (HTTPS)
- Site architecture
4. Social Signals (Minor)
- Social media mentions
- Brand searches
- Engagement metrics
Calculation Process:
- Moz’s web crawler (Rogerbot) indexes the web
- Data collected on links, content, and technical factors
- Machine learning model analyzes all signals
- Score calculated on logarithmic scale (1-100)
- Scores updated monthly in Moz’s index
Why Logarithmic Scale Matters:
- Going from DA 20 to 30 is relatively easy (2-3 months)
- Going from DA 30 to 40 is harder (6-12 months)
- Going from DA 60 to 70 is extremely difficult (years)
- Each 10-point increase requires exponentially more effort
Why should Domain Authority be checked?
The domain authority of a website gives a detailed report of its relevance for a specific search topic, so to learn about your website’s ranking ability, the domain authority must be checked.
People often like it when their website ranks higher on the search engine results page, so to make sure one gets a high rank, one should always check their domain authority.
Along with predicting the rank on SERPs, domain authority also includes other things such as the prestige of the website and its authors and the quality of the information presented.
How to Increase Website Domain Authority
There are lots of factors available in the digital marketing world to improve the DA of your website, but here we are sharing a few of them:

- Boost your content marketing strategy.
- Work on on-page & off-page activities.
- Outreach with niche bloggers.
- Build natural links for your website.
- Share your content on social media platforms.
- Make a mobile-friendly website.
- Remove spammy & bad backlinks.
- And more importantly, you should have patience.

Common DA Checking Mistakes to Avoid
Mistake 1: Obsessing Over DA Score
The Problem: Many website owners become fixated on their DA number, checking it daily and panicking over small fluctuations.
Mistake 2: Comparing DA Across Different Tools
The Problem: Using multiple tools and getting confused when numbers don’t match.
Mistake 3: Buying Backlinks to Increase DA
The Problem: Purchasing backlinks from link sellers, thinking it’s a shortcut to higher DA.
Mistake 4: Ignoring Page Authority (PA)
The Problem: Focusing only on Domain Authority and neglecting Page Authority.
Mistake 5: Not Checking Competitor DA
The Problem: Checking your own DA in isolation without a competitive context.
Mistake 6: Expecting Immediate DA Increases
The Problem: Building 10 backlinks and checking DA the next day, expecting to see improvement.
Mistake 7: Using Only Free Tools for Professional Work
The Problem: SEO agencies or professionals relying solely on free DA checkers for client work.
Mistake 8: Neglecting Toxic Backlinks
The Problem: Focusing only on building new links, ignoring harmful links pointing to your site.
Mistake 9: Thinking DA = Rankings
The Problem: Believing that increasing DA automatically improves Google rankings.
Mistake 10: Checking DA Too Frequently
The Problem: Checking DA multiple times per week or even daily.
Final Thoughts: Use DA as a Guide, Not a Goal
Domain Authority is a valuable metric for assessing website authority and tracking SEO progress, but it should never become your primary focus. Remember that DA is a Moz-created metric, not a Google ranking factorโyour ultimate goal is ranking well in Google search results and driving organic traffic, not achieving a specific DA number.
Key Takeaways:
โ
DA predicts ranking potential, but doesn’t guarantee rankings
โ
Check DA monthly, not daily (it only updates monthly anyway)
โ
Focus on the factors that improve DA: great content + quality backlinks
โ
Compare your DA to direct competitors, not arbitrary targets
โ
Track DA trends over 6-12 months, not month-to-month fluctuations
โ
Use free tools for casual checking, paid tools for professional work
โ
Remember, PA matters too for individual page rankings
โ
Be patientโmeaningful DA growth takes 6-12+ months
The websites that succeed long-term don’t obsess over DA scores; they consistently create valuable content, build genuine relationships that naturally earn quality backlinks, provide exceptional user experiences, and let DA increase as a byproduct of good SEO practices.
Use the DA PA checker tools in this guide to monitor your progress, identify opportunities, and stay competitiveโbut invest your time and energy in the activities that actually drive business results: creating content people love, building links ethically, and delivering value to your audience.
FAQs :
DA measures the ranking potential of your entire website, while PA measures the strength of individual pages. DA is your siteโs overall reputation (1โ100), and PA shows how strong each page is based on backlinks and optimization.
Moz updates DA about once per month. Even if you build new backlinks, changes appear only after the next Moz index refresh, usually every 30 days.
Yes. You can check DA for free using tools like Moz Link Explorer, MozBar, Small SEO Tools, Prepost SEO, or The HOTH. Moz offers 10 free checks per month, while other tools allow unlimited free lookups.
No. Google does not use DA in its algorithm. DA is a Moz metric that estimates ranking potential, but improving DA usually aligns with good SEO practices that help real rankings.
New sites typically start with a DA of 1โ10. After consistent SEO work, reaching DA 20โ30 within a year is a healthy goal. Growth slows as scores get higher, so focus on steady improvement over time.
Earn high-quality backlinks, publish valuable content, guest post on reputable sites, remove toxic links, and improve internal linking. Be patientโDA growth usually takes a few months.
