Entity SEO
Entity SEO is writing and marking up your site so search engines treat your company, product, people and concepts as entities, not strings of words. It helps small sites get named correctly in search, AI overviews and assistants. You do this with one name, clear pages and consistent facts on and off your site.

Entities against strings, in practice
Search engines store facts about things in a knowledge graph. A string is just text. An entity is a thing with attributes and links to sources.
You want your product, company and key people to exist as entities there. Then your pages map to them. Assistants read the same sources and use the same names.
In practice this is simple. Use one consistent name. State what the thing is in the first sentence on its page. Add Organization markup with sameAs links. Keep facts the same on directories, review sites and, where it applies, Wikidata.
What it means for a small site
You cut ambiguity. You make it easy for Google to connect your pages, your profiles and mentions to one thing. That reduces mix ups with namesakes.
You also help AI answers say your name the same way. That can push correct citations and links. It also clarifies brand versus generic queries in reports.
A fixed page looks like this: "/about" opens with "YourProduct is project tracking software for architects." The same words appear on LinkedIn, Crunchbase and your GitHub org page. Your Organization JSON-LD links to those profiles in sameAs.
How to check and measure
- Search your exact name in quotes. See if results cluster to you, your site and your profiles.
- Check for a knowledge panel on brand or founder searches. If one shows, review the sources it cites for accuracy.
- Validate your Organization markup. Use JSON-LD and include sameAs links to the profiles that describe you.
- Audit third-party facts. Company type, founding date, domain, logo and description should match across profiles and directories.
- Watch branded queries in Search Console. Track impressions, clicks and variations of your name.
- Read AI overviews and assistants for your topic. See how they name you and which sources they cite.
You cannot see a public list of the graph entries that define you. You infer it from consistent naming, panels that appear, and how assistants refer to you, as of 2026.
What to implement on your site
Set one name and description
Write the first sentence on "/", "/about" and "/product" to say what it is. Example: "YourProduct is time tracking software for agencies."
Add Organization markup
Use JSON-LD on every page. Include name, url, logo, sameAs links to your key profiles. Keep the name identical to your on-page text.
Mark up products and people
Add Product or SoftwareApplication for products. Add Person for founders or authors on "/about" and posts.
Link out to your profiles
Place visible links to LinkedIn, GitHub, YouTube and key listings. Use the same logo and description text.
Tidy third-party facts
Claim profiles. Fix names, domains and summaries. Add your site link. Update any mismatched dates or categories.
State facts on-page
Add a concise facts block on "/about": company type, HQ city, year founded, team size, support email. Keep it in normal text.
Keep titles and H1s clear. Avoid clever names that hide what you are. Internal links should use the entity name and the type, for example "YourProduct project tracking" to "/product".
Common traps and how to avoid them
- Multiple names across pages and profiles. Pick one and fix the rest.
- Vague homepages. Say what it is in the first sentence, not a tagline.
- Missing sameAs. Add LinkedIn, GitHub, Crunchbase or similar profiles you control.
- Inconsistent facts on directories and review sites. Align them with your site.
- Overstuffed schema. Stick to facts you show on the page and that are true.
- Changing names or domains without redirects or updates. Map and update every profile when you rebrand.
Questions
An entity is a real thing in a knowledge graph, like a company, product, person or concept. It has attributes and links to sources. It is not just text on a page.
It is the work of naming, writing and marking up your site so search engines and assistants recognise your company and product as entities. You do this with one name, clear first sentences, Organization markup with sameAs, and consistent facts on and off your site.
Yes. You still match queries with useful pages. Entity work removes ambiguity about who you are. Keywords tell the engine which problems you solve and for whom.
Not always. Use it where it applies and you can meet its notability rules. For most small sites, well marked pages and consistent third-party profiles are enough to start.
Assistants use sources that also feed search knowledge. If your name and facts match across your site and profiles, assistants are more likely to name you correctly and cite you.
It varies. Crawling and reprocessing can take weeks. You can often speed it up by fixing on-site text now and updating key profiles in the same week.
