Domain Authority (DA) predicts how likely an entire website is to rank on search engines, calculated using over 40 signals including linking root domains and total backlinks. Page Authority (PA) predicts how likely a single specific page is to rank, using page-level link equity and internal links.
Both use a 1–100 scale, but DA changes slowly (months to years) while PA can improve in days. Track DA for site reputation and link building. Track PA for ranking individual pages. Yes, Page Authority can be higher than Domain Authority when a single page earns strong backlinks that the rest of the domain lacks.
You’ve probably seen them in SEO tools — two scores between 1 and 100, both claiming to predict your ranking potential. They sound almost same. Most guides treat them as interchangeable.
And using the wrong one? That’s how you waste months optimizing the wrong pages while your competitors quietly outrank you.
Here’s the 10-second difference before we go deep:
Domain Authority predicts how well your entire website will rank.
Page Authority predicts how well a single URL will rank.
By the end of this guide, you’ll know exactly which metric to track, when to ignore both, and how to raise the scores that actually move traffic.

What Is Domain Authority?
Domain Authority is a search engine ranking score that predicts how likely a website is to rank on search engine result pages (SERPs). It runs from 1 to 100. Higher scores = higher probability of ranking.
Domain Authority (DA) was created by Moz in the early 2010s. Today, it’s the most widely referenced SEO metric for measuring website strength — though competitors like Ahrefs (Domain Rating) and Semrush (Authority Score) have their own versions.
How it’s calculated (simplified):
Moz’s algorithm looks at over 40 factors, but the heavy lifters are:
- Linking root domains (number of unique websites linking to you)
- Total backlinks (all incoming links)
- Link quality (authority of those linking domains)
- MozRank (Moz’s version of PageRank)
- MozTrust (distance from trusted seed sites)
What DA is NOT:
- ❌ A Google metric (Google has never confirmed using it)
- ❌ A ranking factor (it predicts rankings, not causes them)
- ❌ Static (it fluctuates as the web changes)
- ❌ Comparable across wildly different industries
For Example:
A new blog with 10 backlinks might have a DA of 8. The New York Times has a DA of 94. Your local plumber with a decent site might sit around DA 25-35.
Why Domain authority Matters?
DA gives you the forest-level view. It answers: Is this website generally trusted by search engines? Low DA doesn’t mean you can’t rank. But high DA means almost everything you publish has a head start.
Is Domain Authority a Google ranking factor?
No. Domain Authority is a third-party metric created by Moz, not Google. Google has never confirmed using DA in its ranking algorithms. However, DA strongly correlates with rankings because it uses similar signals — backlinks, linking root domains, and site trust — that Google also values.
What Is Page Authority?
Page Authority is a search engine ranking score that predicts how likely a single specific page is to rank on SERPs. Same 1-100 scale. Calculated using similar factors — but focused on the page level. If DA is the forest, Page Authority (PA) is the tree. DA tells you your site’s potential. PA tells you which specific pages are actually realizing that potential.
How it’s calculated:
PA looks at page-level signals, including:
- Page-level link equity (backlinks pointing to that specific URL)
- Internal links from other pages on your site
- Page content quality (indirectly, via engagement signals)
- Technical factors (page speed, mobile optimization, etc.)
What PA is Good for:
- Comparing two blog posts on the same site
- Deciding which page to build links toward
- Diagnosing why one page ranks and another doesn’t
- Tracking progress of a specific landing page
For example:
Your homepage might have PA 52 (lots of internal and external links). But a deep blog post from 2019 with zero internal links? PA could be 11. That blog post won’t rank for anything competitive until you raise its PA.
Do internal links affect Page Authority?
Yes — strongly. Internal links from high-PA pages on your own site transfer link equity directly to target pages. This is the fastest, most underrated way to raise PA. Fix orphan pages (zero internal links) and link from your homepage to priority content.
Domain Authority vs Page Authority: The 7 Differences That Matter
These are 7 Differences which can help you to clearly understand the importance of Domain Authority and Page Authority for your website.
| Differences | Domain Authority | Page Authority |
|---|---|---|
| Scope | Entire website (all pages) | Single URL (one page) |
| What it predicts | Overall domain ranking ability | Individual page ranking ability |
| Changes slowly? | Yes — months to years | Can change in days |
| Best for | Comparing sites, vetting link opportunities | Prioritizing content, building link strategies |
| Worst for | Diagnosing page-specific issues | Comparing across different websites |
| Improvement speed | Slow (needs domain-level links) | Fast (targeted page links) |
| Typical range by site age | New: 1-20 / Medium: 25-50 / High: 60+ | Varies wildly by page |
Your DA is the ceiling. Your PA is where specific pages sit relative to that ceiling. A site with DA 70 probably has most pages with PA 40-65. A site with DA 25 might have one page with PA 48 if it earned strong links. That single PA 48 page can outrank a DA 70 site’s PA 35 page for a specific query.
Which One Should You Actually Track?
This is where most guides stop being useful. They explain the difference, then leave you confused about what to do. Don’t track both equally. Track based on your goal.
You Should Track Domain Authority when:
- You’re evaluating a potential link partner
- You’re comparing your site to competitors
- You’re planning a site-wide SEO overhaul
- You’ve just launched a new domain and need a baseline
- You’re reporting to leadership who wants one “health score”
Don’t track DA when: You’re trying to improve a single page’s ranking. That’s PA’s job.
Track Page Authority when:
- You’ve published a new post and want it to rank
- You’re deciding between two pages to build links toward
- One page is underperforming compared to similar pages on your site
- You’re doing internal link optimization
- You want to see if your link-building worked within weeks (not months)
The hybrid approach (what advanced SEOs do):
- Use DA as a filter — don’t waste time on pages/sites below your threshold
- Use PA as a lever — raise PA on your money pages first
- Monitor both monthly — DA trends up slowly, PA trends up with activity
One Important SEO Rule
Track DA for your domain’s reputation. Track PA for your page’s ranking potential.
Can Page Authority Be Higher Than Domain Authority?
Yes. Frequently. And it’s not a bug — it’s a feature. A single page earns high-quality backlinks that the rest of your domain doesn’t have. You can rank a single page for competitive keywords even with a low-DA site. It’s harder. But it’s possible.
For Example, You write a guide called “Best SEO Tools for Small Business 2026.” A DA 92 site (HubSpot) links to that specific guide. That one link dramatically raises that page’s PA — sometimes above your domain’s DA. Your DA stays the same (one link doesn’t change domain-level authority much). But that page’s PA jumps.
Page Authority above Domain Authority is often temporary. Without ongoing links, PA drifts back down. And that page won’t lift other pages on your site much that’s what DA is for.

How to Improve Domain Authority of Website?
Everyone wants higher DA. Most advice is useless: “Get more backlinks.” I am giving you 4 Strategies which will help you to improve your website Domain Authority in long term.
Strategy 1: Fix leaking link equity
The insight: Many low-DA sites have high-quality backlinks pointing to pages that 404 or redirect poorly.
What to do:
Run a broken backlink check (use Ahrefs or Semrush free trials). Find 404 pages with external links. Redirect them to relevant live pages.
Expected DA impact: 5-15% increase within 3 months if you have significant broken backlinks.
Strategy 2: Remove toxic links (don’t just disavow)
Google’s disavow tool is passive. Removing links is active.
What to do:
Identify spammy or low-quality domains linking to you. Email them with a removal request (use a template). Document attempts. Then disavow only the unresponsive ones.
Expected DA impact: Prevents future drops. Rarely raises DA alone.
Strategy 3: Build fewer, better links
One link from a DA 70 site is worth 100 links from DA 10 sites.
What to do:
Stop chasing “250 backlinks for $20” services. Start creating resources worth linking to: original research, free tools, definitive guides, data visualizations.
Expected DA impact: Slow but permanent. 1-2 points per high-quality link.
Strategy 4: Internal link strategically
This is the most underrated DA lever.
What to do:
Ensure your highest-PA pages link to your next-priority pages. Don’t let link equity die on pages nobody visits.
Expected DA impact: Marginal on DA directly, but raises PA across your site — which eventually lifts DA.
How long does DA improvement take?
3-6 months for noticeable movement. 12-18 months for significant jumps. Anyone promising faster is selling something.
How to Improve Page Authority (Faster Wins)
To improve Page Authority (PA), focus on four proven methods ranked by effectiveness. First, add internal links from your site’s highest-PA pages to your target page — this transfers link equity and shows results within 7-14 days. Second, earn one relevant external backlink from a domain with DA 30+ in your niche — this has more impact than 100 low-quality links.
I have arranged 4 Proven Methods which help you to improve the Page authority score. Follow these methods and implement on your website.
Method 1: Internal links from high-PA pages
Find your site’s highest-PA page (likely homepage or most-linked post).
Link from that page to the target page using relevant anchor text.
Impact: PA increase within 7-14 days.
Method 2: One good external link
One link from a relevant DA 50+ page to your target page.
Not 100 spammy links. One good one.
Impact: PA increase within 2-4 weeks.
Method 3: Update old content (freshness signal)
Google doesn’t use PA directly. But fresh content increases engagement, which influences ranking factors.
What to do:
Add 300+ new words. Update statistics to current year. Add new examples. Republish with current date.
Impact: Indirect PA increase. Direct ranking improvement.
Method 4: Fix orphan pages
Pages with zero internal links are orphans. Search engines find them harder. They accumulate less PA.
What to do:
Run a site audit (Screaming Frog free under 500 URLs). Find pages with zero internal links. Add links from relevant parent pages.
Impact: PA increase within 2 weeks for discovered pages.
The fastest PA improvement method:
Internal links from your highest-PA page + one relevant external link.
Common Mistakes SEOs Make (And What to Do Instead)
Mistake 1: Obsessing over DA below 30
If your site is less than 12 months old, your DA will be low. That’s normal.
What to do instead: Track PA on your best content. DA matters more when you’re competing with established domains.
Mistake 2: Ignoring DA for link building
“I’ll link from anyone who asks.”
What to do instead: Set a minimum DA threshold for link partners. DA 20+ if you’re new. DA 30+ as you grow.
Mistake 3: Comparing DA across different tools
Moz DA 45 ≠ Ahrefs DR 45. Different scales. Different calculations.
What to do instead: Compare within the same tool only. Or use percentiles instead of raw scores.
Mistake 4: Thinking PA and DA move together
They don’t. You can raise PA on one page while DA stays flat. That’s fine. That’s expected.
What to do instead: Set separate goals. DA: +5/year. PA on money pages: +10/quarter.
The Future of Authority Metrics (2026 and Beyond)
Three shifts already happening:
Shift 1: Google’s own “authority” signals are replacing third-party metrics
Google has used PageRank for decades. Now they have:
- E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness)
- Site-wide classifiers (core updates that demote whole domains)
- Link quality refinement (ignoring more low-quality links)
Third-party metrics like DA will become less important — not irrelevant, less important.
Shift 2: AI search tools use different authority signals
ChatGPT, Perplexity, and Gemini don’t use DA. They use:
- Citation frequency (how often your site is cited by other AI-trained sources)
- Content originality (AI detection bypass)
- Freshness (newer content preferred for many queries)
What this means: Authority is fragmenting. Domain Authority matters less for AI search. Page-level uniqueness matters more.
Shift 3: Niche authority > general authority
A DA 40 medical blog written by actual doctors might outrank a DA 80 general news site for health queries.
Google increasingly prefers specialized relevance over general domain strength.
What this means for you: Build authority in your specific corner of the internet. General DA matters less than topic-specific trust.
The Bottom Line (In 3 Sentences)
Domain Authority measures your site’s reputation. Improve it for long-term SEO health and link-building credibility.
Page Authority measures a page’s ranking potential. Improve it for faster wins and specific keyword targets.
Track both. Optimize page authority first. Let domain authority grow as a byproduct of consistent, quality work.
