Entity SEO vs keyword SEO

By Nathan Woo

What is keyword SEO?

Keyword SEO focuses on optimizing pages for specific search terms. The goal is to include target keywords in titles, headings, and content to rank for those queries.

Traditional keyword research identifies high-volume, low-competition terms to target.

Keyword density, placement, and variations were once the primary optimization factors.

While still relevant, keyword-only approaches miss how modern search engines understand content.[2]

What is entity SEO?

Entity SEO focuses on establishing your website as a collection of well-defined entities with clear relationships.

Instead of just targeting "spine surgeon Los Angeles," entity SEO defines your practice as an entity connected to location, specialty, conditions, and treatments.[1]

Search engines use entity understanding to match queries with intent, not just keywords.[2]

Entity SEO involves structured data, knowledge graph optimization, and building a coherent entity identity.

Why entity SEO matters more now

Semantic search: Google understands synonyms, context, and meaning. You don't need exact-match keywords if your entity is well-defined.[1]

AI comprehension: AI tools understand entities better than keyword strings. Clear entity definitions improve AI citation likelihood.

Voice search: "Hey Google, find me a spine surgeon near me" is an entity query, not a keyword query.

Knowledge panels: Entity-rich sites are more likely to earn knowledge panels and enhanced search features.

Using both approaches

Entity and keyword SEO aren't mutually exclusive. Keywords inform entity attributes and help target specific queries.

Start with entities: Define your practice, providers, services, and conditions as entities.

Layer in keywords: Ensure your entity content includes the terms patients actually search.

Build relationships: Connect your entities to each other and to broader concepts in your field.

Key takeaways

  • Keyword SEO targets specific search terms
  • Entity SEO defines what your site is about semantically
  • Modern search engines prioritize entity understanding
  • Best practice: combine entity structure with keyword targeting

Entity SEO explained

Read summary

When patients search for "orthopedic surgeon near me," Google isn't just matching keywords anymore – it's looking for known, trusted entities. If your practice isn't established as an entity in Google's Knowledge Graph, you're invisible to both traditional search and AI tools like ChatGPT.

Knowledge graph optimization

Read summary

Google's Knowledge Graph is a database of billions of entities and their relationships. When your practice is properly represented in it, you become a recognized entity rather than an anonymous string of text – which is what lets you appear in knowledge panels, earn AI Overview citations, and be confidently recommended by AI tools. This guide explains how the Knowledge Graph builds an entity for your practice and the concrete steps that get you into it.

Healthcare-specific

AEO for healthcare

Read summary

Answer Engine Optimization (AEO) for healthcare is the practice of structuring your medical practice's online presence so that AI tools – ChatGPT, Google AI Overviews, and others – cite, recommend, and surface your practice when patients ask health-related questions. As AI search tools handle an increasing share of patient research, the practices that appear in AI-generated responses gain a significant acquisition advantage over those that only optimize for traditional search rankings.

Orthopedic patients actively research providers online – nearly 60% of US adults search for health information online. They search for specific conditions, procedures, and specialists before choosing who to trust with their care. If your practice isn't visible in Google and AI search results, you're losing patients to competitors who are.
