Entity SEO explained

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.

Structured data tells search engines exactly what your practice does, where it is, and who works there – in a language they can parse directly. For healthcare sites, proper JSON-LD implementation can unlock rich results, improve local visibility, and make your content citable by AI tools.

SEO has evolved from matching keywords to understanding entities. While keywords still matter, modern search engines prioritize understanding what entities exist on your site and how they relate to searcher intent.

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.

Spine patients spend significant time researching before choosing a surgeon – nearly 60% of US adults search for health information online. They search for specific conditions, compare surgical approaches, and look for specialists with relevant experience. Your online presence directly impacts whether they find you or your competitors.

Chronic pain patients are desperate for relief and actively searching for solutions. With over 51.6 million US adults living with chronic pain, the need is substantial. They compare treatment options, research providers, and look for specialists who understand their condition. Your online visibility determines whether they find your practice or turn to someone else.

Your website shows up on Google. Your SEO reports look healthy. But the phones aren't ringing like they used to. You're not imagining it – something fundamental has changed in how patients find and choose healthcare providers.

Patients are telling you they "asked ChatGPT" or "checked with AI" before booking. When you try the same queries, your practice doesn't come up. Meanwhile, competitors – sometimes with fewer credentials or worse reviews – are getting mentioned. This isn't random, and understanding why is the first step to fixing it.

You've worked hard to earn five-star reviews. Patients love you. But when someone searches for your specialty in your area, you're nowhere to be found. The frustrating truth is that reviews matter for local rankings, but they're not the only factor – and focusing on reviews alone while neglecting other signals can leave you invisible.
