Domain Authority signals matter for AI citation too. While AI systems don’t use DA directly, the underlying signals DA measures—quality backlinks, site reputation, established presence—likely influence AI source selection. Sites that rank well in traditional search often perform well in AI citations because they’ve built genuine authority.
Domain Authority Components
- Link Profile: Quality and quantity of backlinks pointing to the domain.
- Linking Domains: Number of unique domains linking to the site.
- Link Quality: Authority of linking sites matters more than quantity.
- Age and History: Established domains with clean history score higher.
DA Score Interpretation
| Score Range | Authority Level | Typical Sites |
|---|---|---|
| 1-20 | Low | New sites, small blogs |
| 21-40 | Medium | Growing sites, niche publishers |
| 41-60 | Good | Established businesses, popular blogs |
| 61-80 | High | Major publishers, brands |
| 81-100 | Elite | Wikipedia, major news, gov sites |

- Trust Proxy: High DA sites have demonstrated credibility over time.
- Citation Likelihood: AI may prefer sources with established authority signals.
