For 15 years, marketing teams obsessed over "Domain Authority" (DA) — a metric based entirely on how many other websites linked to yours. In the AI era, search engines no longer rely on links to understand the world. They rely on Knowledge Graphs. Consequently, DA is dying, and Entity Authority has taken its place.
1. The Old Model: Links as Votes (Domain Authority)
Domain Authority is a metric (invented by Moz, not Google) that predicts how likely a website is to rank in traditional search engine results pages (SERPs). It operates on a simple premise: a hyperlink from Website A to Website B is a "vote of confidence."
Therefore, if you buy or earn 1,000 backlinks to your blog post, Google assumes your post is authoritative and ranks it #1 for a specific keyword. This created a massive, gamified industry of link-building.
2. The Flaw in Domain Authority
The link-graph model broke down because it was too easy to manipulate. Companies bought links on irrelevant sites just to boost their DA score.
More importantly, an LLM (like the one powering Perplexity or ChatGPT) doesn't care how many links point to a page. When an LLM reads a document, it evaluates the semantic density and the factual accuracy of the text. A high DA score cannot save an article that lacks dense, extractable information.
3. The New Model: Entities and Knowledge Graphs
AI systems understand the world through entities (people, places, organizations, concepts) and the relationships between them.
Entity Authority is a measure of how confident an AI model is that your brand is a legitimate, established solution within a specific category.
AI models build this confidence not by counting backlinks to your homepage, but by looking for:
- Presence in structured databases (Wikidata, Wikipedia).
- Consistent NAP (Name, Address, Phone) data across G2, Crunchbase, and LinkedIn.
- Semantic co-occurrence (being mentioned in the same sentence as industry leaders in high-quality publications).
- Implementation of robust

4. DA vs. Entity Authority Comparison
| Metric | Domain Authority (Old) | Entity Authority (New) |
|---|---|---|
| Primary Signal | Quantity and quality of backlinks. | Data consistency and structured relationships. |
| Target Destination | A specific URL (e.g., your homepage). | The brand concept (regardless of URL). |
| Primary Tactic | Guest posting, link insertion outreach. | Schema markup, Digital PR, Wikidata. |
| Vulnerability | Highly susceptible to algorithmic penalties. | Highly resilient; grounded in mathematical facts. |
5. The Strategic Shift for Marketing Teams
If your marketing agency is reporting on "Domain Authority" and "Number of Backlinks Built," they are operating on a 2018 playbook.
The new KPIs for AI Visibility are:
- Share of Voice in AI Overviews: Are you cited when a buyer asks Google about your category?
- Knowledge Panel Generation: Has Google recognized your brand as a distinct entity in its Knowledge Graph?
- LLM Retrieval Rate: When you ask ChatGPT Enterprise for recommendations in your space, does it output your brand name?
Frequently Asked Questions
Should we stop trying to get backlinks completely?
No. A link from a highly relevant, high-authority site (like Forbes or a major industry blog) is still valuable. But it is valuable because of the context and the co-occurrence of the entities in the text surrounding the link, not just because of the link itself. Stop buying cheap links; start executing strategic PR.
Can a brand with low DA have high Entity Authority?
Yes. We frequently see startups with a DA of 20 outrank massive incumbents with a DA of 80 in Perplexity and AI Overviews, simply because the startup structured their data perfectly and provided denser, more extractable answers to specific questions.
