Before reading any number on this page, understand where it comes from. These benchmarks are drawn from a combination of publicly available industry research, patterns observed across SEO campaigns we have managed, and aggregated data published by major crawl and link intelligence platforms including Ahrefs, Semrush, Moz, and Majestic.
Where we cite a specific range, we have noted its source type. Three categories appear throughout:
- Platform-published data: Figures released by tool vendors in their own research reports. These reflect their data sets, which vary in size and methodology.
- Industry-aggregated estimates: Ranges cited consistently across multiple independent SEO research sources. These represent a reasonable consensus, not a single authoritative study.
- AuthoritySpecialist observed ranges: Patterns from campaigns we have run directly. Where a range comes from that work, the text says so.
A standing note applies to every table and range on this page: benchmarks vary significantly by market, domain age, content volume, and vertical competition level. A domain authority score that signals strength in a local services niche may be below average in financial services or enterprise SaaS. Always interpret these figures within your competitive context, not in isolation.
We update this page when materially new data becomes available from credible sources. Where specific numbers have aged, we note the publication year so readers can assess freshness independently.
Labeling each figure by source type also makes trend analysis easier. If a vendor changes its index or scoring method, you can separate a measurement-system change from a genuine change in the domain itself.
