Domain Authority Explained: What It Is and How to Improve It

What Is Domain Authority (and Why It's Confusing)?

"Domain Authority" (DA) is a proprietary metric created by Moz. "Domain Rating" (DR) is Ahrefs' equivalent. They both estimate how authoritative a domain is based primarily on its backlink profile.

Neither is used by Google in their ranking algorithm. Google doesn't have a single "authority score" — it evaluates pages based on hundreds of signals including content quality, relevance, backlinks, and user engagement.

So why does DA/DR matter?

Because it's a rough correlate of ranking ability. Sites with high DR tend to rank better — not because of the DR score itself, but because the same factors that produce high DR (quality backlinks from many domains) also produce better rankings.

Understanding this distinction is important. You don't improve rankings by improving your DA score. You improve rankings by building quality backlinks and producing great content — which then increases your DA as a byproduct.

How Domain Authority Is Calculated

Moz Domain Authority (0–100 logarithmic scale)

Moz's DA is based on:

Linking root domains (how many unique domains link to you)
MozRank (link quality, not just quantity)
MozTrust (link quality from trusted sources)
Other factors in Moz's algorithm

The logarithmic scale means it's much harder to go from DA 50 to DA 60 than from DA 10 to DA 20. Most new sites start at DA 1–5. Getting to DA 30 takes significant effort.

Ahrefs Domain Rating (DR)

Ahrefs' DR is calculated based on:

Number of referring domains linking to your site
The DR of those linking domains
How many external links those domains have

A link from a DR 80 site that links to only 10 sites is worth more than a link from a DR 80 site that links to 10,000 sites. Ahrefs calls this "link equity distribution."

Which one should you track?

Pick one and track it consistently. Moz DA and Ahrefs DR often differ by 10–20 points for the same domain. The relative score within one tool is what matters — not the absolute number or comparison between tools.

Most SEO practitioners prefer Ahrefs DR for its more consistent methodology, but both are fine for directional tracking.

Why New Sites Have Low DA and What That Means

A new domain starts at DA 1 / DR 0. This isn't a punishment — it's simply the absence of data. Google hasn't seen any backlinks to your domain yet.

What low DA means for ranking:

Competitive keywords (KD 40+) are essentially unrankable on a new domain
Medium keywords (KD 20–40) will take 6–12 months to rank for
Long-tail keywords (KD < 20) are absolutely rankable on a new domain — often within weeks

The good news: DA/DR don't prevent ranking for the right keywords. A DR 0 domain can rank for a KD 5 keyword if the content is good and the SERP is weak. Topical authority — built through content clusters — compensates for low domain authority on specific topic areas.

Many bootstrapped founders waste 12 months trying to rank for competitive keywords on a new domain. The solution isn't to build more backlinks (slow, difficult) — it's to target long-tail keywords that your low-DA domain can actually win.

How to Improve Domain Authority (Practical Approach)

DA/DR improve by acquiring more high-quality backlinks. Here's how to do it without a formal link building campaign:

1. Earn links with linkable content

The most sustainable way to earn backlinks is to publish content that other people want to cite:

Original data and research: A survey of 200 founders about their SEO spending is inherently citeable. If your data is original and interesting, people will link to it naturally.

Comprehensive guides: Long-form, genuinely comprehensive guides earn links because they become the go-to reference for a topic. A 5,000-word guide on "SEO for bootstrapped founders" is more linkable than a 500-word tip list.

Free tools: A free keyword difficulty calculator or content brief template earns links from users who find it useful. Tools require upfront investment but earn links passively.

2. Get listed in relevant directories

Product Hunt, G2, Capterra, AlternativeTo, GetApp — each listing includes a link to your domain. Setup time: 30–60 minutes total. These are relevant, authoritative links in your product category.

3. Guest contributions to industry publications

Write one high-quality guest post per quarter for Indie Hackers, Hacker News (Show HN), or a relevant niche publication. Don't pitch generic content — write genuinely useful tactical content that demonstrates expertise. The author bio link is the backlink.

4. Build in public

Sharing your progress (revenue milestones, SEO learnings, product decisions) on Twitter/X, LinkedIn, and community forums generates natural social mentions that often convert to links. Founders who share specific data ("Month 6: 2,400 organic sessions, here's my exact content strategy") consistently earn links from other founders who reference their work.

5. Competitor backlink analysis

Use Ahrefs or Semrush to see where your competitors get their backlinks. Any site that links to a competitor can potentially link to you. Look for:

Industry round-ups and "best tools" lists
Resource pages
Relevant blog articles that mention your competitors but not you

Reach out to these sites with a specific reason why your product should be included.

The Realistic DA/DR Timeline

For a new domain with consistent link building:

Month 3: DR 5–10. First backlinks from directory listings and community posts.
Month 6: DR 15–25. Links from 20–50 referring domains. Long-tail rankings coming in.
Month 12: DR 30–45. Links from 50–150 referring domains. Medium-difficulty commercial keywords starting to rank.
Month 24: DR 45–60 (with active link building). Competitive commercial keywords within reach.

These are ranges — actual progress depends heavily on the quality and quantity of backlinks you earn.

What NOT to Do to Improve DA

Buying backlinks

Buying links is a Google policy violation and a major spam signal. Short-term ranking gains from purchased links are typically followed by manual or algorithmic penalties that are difficult to recover from.

Link exchanges at scale

A handful of informal link exchanges with genuinely related sites is normal. Operating a formal "link exchange network" is a violation of Google's guidelines.

Targeting DA/DR improvements directly

If you're doing things specifically to move your DA number — joining link networks, buying listings on directories you don't care about — you're optimizing for a proxy metric, not for actual ranking improvements. Focus on earning links that drive referral traffic and brand awareness; DA improvement will follow.

DA vs. Page Authority: When to Use Each

Domain Authority (DA): Measures the authority of the entire domain. Use for competitive analysis — "can I realistically rank against this competitor?"

Page Authority (PA): Measures the authority of a specific page. Use when evaluating whether a specific competing page has enough backlinks to be hard to beat.

When doing keyword gap analysis, look at page authority of the specific pages you'd be competing against — not just the domain authority. A DR 80 domain (hard to beat) might have a specific page with PA 20 (very beatable) if that page has few backlinks.
