How Domain Authority Is Calculated

Domain Authority is calculated using machine learning algorithms that analyze hundreds of ranking signals including:

1. Backlink Profile

The quality and quantity of backlinks remain the strongest factor.

High-quality backlinks from trusted websites increase DA.

2. Referring Domains

Getting links from many unique websites is better than receiving hundreds of links from the same domain.

3. Link Quality

Links from authoritative websites carry much more value than links from low-quality websites.

4. Website Trust

Trusted websites with strong reputations usually have higher Domain Authority.

5. Spam Signals

Websites with excessive spammy backlinks may experience lower authority scores.

6. Internal Linking

A well-organized internal linking structure helps distribute authority across your website.

7. Overall SEO Health

Technical SEO factors contribute indirectly by improving crawlability and user experience.

What Is a Good Domain Authority Score?

There is no perfect DA score because it depends on your niche.

DA Score	Meaning
1–10	Brand new website
11–20	Beginner website
21–30	Average website
31–40	Good authority
41–50	Strong website
51–60	Excellent authority
61–70	Highly authoritative
71–80	Industry leader
81–100	Global authority

Instead of chasing a specific number focus on having a higher DA than your competitors.
