Cluster 24: Backlinks And Authority
What Is Domain Authority?
Domain Authority (DA) is a proprietary search engine ranking score developed by Moz that predicts how likely a website is to rank on search engine results pages (SERPs). Scored on a logarithmic scale from 1 to 100, DA evaluates root domains and link equity to measure overall website ranking strength.

Why Domain Authority Matters
Mechanics
How Domain Authority Works
Domain Authority is calculated by combining multiple link-based metrics into a single score:
- Linking Root Domains: The number of unique websites linking back to your site.
- Total Link Count: The volume of total inbound links pointing to your domain.
- Link Quality: The relative authority and relevance of the sites linking to you.
- Spam Assessment: Signals that identify manipulative or low-quality backlink profiles.
Because DA is calculated on a 100-point logarithmic scale, increasing your score from 20 to 30 is significantly easier than moving from 70 to 80.
Application
Domain Authority Example
A boutique accounting firm launched a targeted digital PR and link-building campaign to earn features in financial publications and local business journals. Over six months, their unique referring domains grew from 20 to 95, increasing their Domain Authority from 18 to 34. Consequently, their core service pages climbed onto page 1 for high-intent search terms like ‘commercial tax advisor,’ resulting in a 45% increase in booked client consultations.
Advantages
Benefits Of A Domain Authority
- Accurate Benchmarking: Compare link equity directly against your top competitors in search results.
- Predictive Campaign Planning: Forecast ranking difficulty before investing resources into competitive target keywords.
- Targeted Link Prospecting: Filter backlink opportunities by identifying high-authority partner sites.
- Increased Organic Revenue: Secure higher rankings on transactional search terms to capture qualified leads.
Pitfalls
Domain Authority Mistakes
- Treating DA as a Google Ranking Factor: Assuming Google uses DA; it is a third-party metric, not an official algorithm signal.
- Prioritizing DA over Content Quality: Chasing scores while ignoring on-page SEO, technical health, and user search intent.
- Buying Low-Quality Backlinks: Purchasing cheap links that trigger search penalties and increase spam scores.
- Expecting Linear Growth: Ignoring the logarithmic scale, which causes teams to set unrealistic growth timelines.

Domain Authority FAQ
Domain Authority FAQs
Is Domain Authority a direct Google ranking factor?
No. Domain Authority is developed by Moz, not Google. Google uses its own proprietary systems and PageRank algorithms to evaluate pages, though DA often correlates with top rankings because it models similar link metrics.
What is considered a good Domain Authority score?
A good score is relative to your direct search competitors. If top-ranking websites in your industry average a DA of 30, a score of 35 is strong. You do not need a score of 90+ to dominate commercial keywords in specific local or niche B2B markets.
How long does it take to increase Domain Authority?
Improving Domain Authority typically takes several months. Moz recalculates scores periodically, and your score will increase as search engines crawl and index newly acquired, high-quality backlinks pointing to your domain.
