The Future of Search: Understanding Entities and the Shift from Keywords to Concepts
Introduction
Imagine a world where search engines no longer focus solely on the words you type, but instead, they understand the deeper meaning behind them. This shift is already happening, transforming how we find information online. Welcome to the era of entities in search engine optimization (SEO).
In the following sections, we’ll cover:
- What entities are and how they differ from traditional keywords
- How Google’s Knowledge Graph and natural language processing (NLP) power entity-based search
- Why optimizing for entities is now essential for SEO and digital marketing
- Easy-to-follow tips for updating your own sites so they don’t get left behind.
- The impact of AI-powered search (like Google’s AI Overviews and ChatGPT) on entity optimization
When we’re done, you’ll get a clear picture of how searches work these days and how to make sure your name still pops up when people look for what you offer.
What Are Entities? The Building Blocks of Modern Search
Entities vs. Keywords: A Clear Shift
For years, SEO revolved around keywords—the exact words and phrases users typed into search engines. But search engines have changed a lot, and these days they care way more about something called entities.
- Keyword: A string of text (e.g., “best Italian restaurant in New York”).
- Entity: A distinct, well-defined concept (e.g., “New York,” “Italian cuisine,” “restaurant reviews”).
Google defines an entity as:
“A thing or concept that is singular, unique, well-defined, and distinguishable.”
Examples include:
- People: Elon Musk, Taylor Swift
- Places: Eiffel Tower, Grand Canyon
- Organizations: Tesla, World Health Organization
- Products: iPhone 15, Tesla Cybertruck
- Abstract concepts: Democracy, Quantum Physics
Why Entities Matter More Than Ever
Entities help resolve ambiguity. For example:
- “Apple” → Is it the tech company or the fruit?
- “Amazon” → The rainforest or the e-commerce giant?
- “Jordan” → The country in the Middle East or the NBA superstar?
When Google identifies the right entity, it can serve up spot-on answers without fumbling around in a pile of different keywords.
How Google Understands Entities: The Knowledge Graph & NLP
The Knowledge Graph: Google’s Brain for Entities
Google’s Knowledge Graph is basically its digital brain. Think of it as a gigantic map that links people, places, and things to each other. Because of this behind-the-scenes tool, we get stuff like:
- Knowledge Panels (those info boxes in search results)
- AI Overviews (direct answers at the top of the search)
- Local Business Listings (Google Business Profiles)
For example, if you type “Leonardo da Vinci” into Google, you don’t just get a list of web pages that mention his name. The search engine grabs the organized info it has about when he was born, what he painted, and which other famous figures were around him.
Natural Language Processing (NLP) & Entity Recognition
Google uses Natural Language Processing (NLP) to:
- Identify entities in text (Named Entity Recognition, or NER)
- Understand relationships between them (via “triples” → subject-predicate-object)
Example:
- “Elon Musk founded Tesla in 2003.”
- Subject: Elon Musk (Person)
- Predicate: founded
- Object: Tesla (Company)
- Attribute: 2003 (Date)
Advanced AI models like BERT and MUM enhance this understanding by analyzing context across multiple languages and media types (text, images, video).
How AI Search Engines Understand Entity
Generative engines like ChatGPT, Perplexity, and Gemini don’t index pages like Google. Instead, they synthesize responses based on entities and relationships they’ve learned or retrieved from the web.
✅ Good to know: If your brand isn’t a well-structured entity, it might be ignored, misrepresented, or replaced in generated answers.
Entities are core to inclusion in LLM responses
An entity with strong signals (mentions, reviews, structured data, backlinks, contextual content) is more likely to be referenced or cited in AI-generated answers.
📈 First Page Sage found that “authoritative list mentions” and “entity strength” are key factors in LLM product recommendations — as much as 40–60% weighting in some engines
They improve content interpretation and citation accuracy
Generative models prefer content that clearly ties back to trusted entities. If your content is vague or your brand isn’t clearly associated with your domain expertise, LLMs may cite a competitor instead.
✅ A strong entity profile = increased chance of being selected, quoted, or linked in generative summaries.

How to Optimize for Entities (Entity-Based SEO)
1. Content Strategy: Semantic Richness & Clarity
- Be explicit: Instead of saying “he” or “they,” name the person or thing directly, like “Barack Obama” or “Tesla.” Clear names leave no room for guessing.
- Use related terms: If you’re talking about “electric cars,” sprinkle in terms such as “battery life,” “charging stations,” and even “Tesla vs. Rivian.” Those extras help paint a fuller picture.
- Structure like Wikipedia: Use headings, mini-info boxes, and links inside your own site. This tidy layout shows Google how different things on the page connect.
2. Structured Data & Schema Markup
- Schema.org markup tells Google exactly what entities your page is about.
- Use the sameAs property to link to authoritative sources (e.g., Wikipedia, Wikidata).
- Local businesses should use the LocalBusiness schema to tie into Google’s local search graph.
3. Leverage AI Tools (with Caution)
- AI-generated content (ChatGPT, Gemini) can help, but still, their output sometimes misses the key players you need to highlight.
- Use entity extraction tools (InLinks, Google’s NER API) to analyze top-ranking content and identify key entities.
4. Adapt to AI-Powered Search (Generative Engine Optimization, GEO)
With AI answers (like Google’s AI Overviews), traditional SEO is evolving into GEO:
- Citations matter more: AI pulls from trusted sources (Wikipedia, major publications).
- Be a “seed site”: Create content so authoritative that AI cites you directly.
- Measure “Share of Model”: Track how often your brand appears in AI-generated answers.

What This Means for Marketers
- Optimize for AI answers, not just rankings.
- Build authority through citations and expert content.
- Focus on entities, not just keywords.
Conclusion: Embracing the Entity-First Mindset
The shift from keywords to entities isn’t just a technical change—it’s a fundamental rethinking of how information is organized online. By optimizing for entities, you:
- Improve search visibility
- Future-proof your content for AI-driven search
- Build deeper connections with your audience
The question isn’t if you should adapt—it’s how fast you can start.
