If you’ve ever wondered what are entities in SEO, the answer is simple: they’re how Google understands meaning beyond keywords. Search engines no longer rely solely on word matching. They now interpret entities like people, places, concepts, and organizations to grasp context and relationships between ideas.
In fact, studies show that web pages optimized with entity-based content achieve over 30% better rankings than those using only traditional keyword strategies. That’s why understanding and finding related entities has become essential for building topical authority and improving search visibility.
In this article, we’ll explain what entities are, why related entities matter for SEO, and how to find and use them effectively to strengthen your site’s relevance and rankings.
What Are Entities in SEO?
An entity in SEO is a distinct, identifiable thing: a person, organization, place, product, concept, or event that search engines can clearly understand.
Unlike keywords, which are just phrases people type into Google, entities carry meaning and relationships. For example, when you write “Apple,” search engines must determine whether you mean the fruit or the tech company. Entities help clarify that context.
Writing with an “entity-first” mindset means focusing on the meaning behind the words. Thus, connecting related concepts in ways both users and algorithms can understand.
Why Related Entities Matter for SEO
When you build content around a main entity (like “digital marketing”) and include related entities (such as “content strategy,” “email automation,” and “customer journey”), you show search engines that your content has depth and context.
Here’s why that matters:
- Enhanced semantic relevance: You’re not just repeating a keyword; you’re creating meaning.
- Improved visibility: Related entities can help your content appear in featured snippets, knowledge panels, and “People Also Ask” boxes.
- Topical authority: Covering related entities signals to Google that your site is an expert resource.
Research shows that content optimized around semantically related terms can experience a 20–30% lift in organic visibility.
Understanding why entities matter is step one. Next, let’s find them.
How to Find Related Entities
1. Use Google’s Own SERP Features
Start with your target keyword and explore Google’s search results:
- Autocomplete suggestions
- People Also Ask boxes
- Related searches
- Knowledge panels
These SERP features reflect what Google already sees as semantically connected. Take note of recurring names, terms, or tools. They’re usually entities you should consider.

2. Analyze Competitors’ Top Pages
Look at the top-ranking pages for your target topic. Use tools like SurferSEO, MarketMuse, or Frase to extract NLP terms and entities from those pages. Identify recurring entities across the best-performing content. Those are likely essential for Google’s understanding of the topic.
If you’re working with a Sacramento SEO agency, they often use these same tools at scale, analyzing entity patterns across multiple local and national competitors to uncover hidden opportunities your brand can capitalize on.
3. Use NLP and Semantic Tools
Tools such as Google’s Natural Language API, TextRazor, or IBM Watson NLU can analyze text and reveal the entities and their importance (salience).
Paste your keyword or competitor content into one of these tools to discover which entities Google already recognizes, then use that insight to strengthen your own content.
Partnering with an experienced SEO agency Sacramento businesses trust can help streamline this process. This also ensures entity mapping and keyword clustering are aligned with local and national search intent.
4. Explore Structured Data and Wikidata
Wikipedia and Wikidata are structured sources that link entities to each other. When you research your core topic there, you’ll find official entity names, relationships, and identifiers.
These can guide how you connect ideas in your content. For example, the entity “Marketing Automation” is connected to “CRM,” “HubSpot,” and “Email Campaigns.”
5. Use Content Gap or Topic Clustering Tools
Platforms like Ahrefs and SEMrush can show which entities or subtopics competitors include but you don’t. Build clusters by creating supporting pages around those missing entities. For instance, a pillar page about “SEO Strategy” could link to cluster articles on “Entity SEO,” “Keyword Mapping,” and “Semantic Search.”
How to Apply Related Entities in Your SEO Strategy
Once you’ve identified your related entities, here’s how to integrate them effectively:
- On-page optimization: Incorporate related entities naturally in headings, paragraphs, and image alt text.
- Internal linking: Connect pages that discuss related entities to build a strong semantic structure.
- Content clusters: Develop pillar pages and supporting pages around shared entities for topical authority.
- Structured data: Use JSON-LD schema to explicitly define entities. Add properties like about, sameAs, and knowsAbout to help search engines interpret your relationships.
- Outbound links: Link to reputable, entity-rich sources (e.g., Wikipedia or official brand sites) when appropriate to strengthen credibility.
Common Mistakes to Avoid
Even with a solid understanding of entity SEO, it’s easy to make small errors that weaken your results. To keep your strategy clean and effective, avoid these common pitfalls:
- Entity stuffing: Using too many entity names unnaturally.
- Ignoring search intent: Entities should add clarity, not confusion.
- Skipping schema markup: Don’t mention entities without structured data support.
- Creating isolated content: Link entity-related pages together.
- Relying only on tools: Use NLP insights, but add human context.
- Neglecting updates: Refresh content as entity relationships evolve.
Conclusion
SEO has evolved from focusing on keywords to focusing on meaning. By identifying and using related entities, you move from optimizing for individual phrases to optimizing the way Google thinks.
