Domain Authority
Moz's proprietary score predicting ranking strength — a useful proxy, not a Google metric.
What is Domain Authority?
Domain Authority (DA) is a proprietary score from Moz — ranging from 1 to 100 — that predicts a website's likelihood of ranking in search engines based on the quality and quantity of inbound links. It is a third-party metric; Google does not use Domain Authority as a ranking signal.
Domain Authority In Practice
Domain Authority is a rough benchmark for two affiliate marketing purposes: estimating the ranking difficulty of competing pages and assessing the link equity value of potential backlinks. A page ranking on DA 80+ domains is harder to displace than one on DA 20 domains, all else equal. However, post-March 2026, AI citation rates show DA correlation dropped to r=0.18 — structured signals, entity resolution, and semantic completeness now outperform raw DA in determining which sources earn AI Overview citations. For new affiliate sites, structured content with proper schema markup and entity cross-references competes effectively against high-DA incumbents in AI search, even when organic rankings remain difficult. Use DA to inform competitive analysis; do not treat it as a proxy for content quality or AI citation potential.
Example of Domain Authority
AffiliateDen with a DA of 15 publishes a glossary page on 'recurring commission' with DefinedTerm JSON-LD, Wikipedia sameAs anchors, and structured cross-references to related program pages. G2 (DA 92) has a passing mention of recurring commissions in a category listing with no dedicated page. In AI search, AffiliateDen's structured, self-contained answer earns citations alongside or above G2's reference — demonstrating that semantic completeness compensates for DA differential in AI Overview results, a shift documented in post-March 2026 citation analysis.
