Entities are the specific things a page talks about: companies, products, people, places and concepts. Entity salience is a measure of how important each one is to the text as a whole. A page that mentions Salesforce once in passing and one that is entirely about a Salesforce integration both contain the entity, but its salience is very different. Making the main entity clearly central helps machines understand what a page is about.
Where the idea comes from
Google's Cloud Natural Language API returns a salience score between 0 and 1 for each entity it finds in a text, and many SEO tools use it as a proxy. That API is a public product, not Google Search's ranking system. Google has not documented how Search weighs entity salience, so treat the score as a useful diagnostic, not a ranking factor.
What makes an entity salient
In practice, entities read as central when they appear in the title and main heading, are the subject of sentences rather than objects in passing, are discussed early, and recur throughout. Clear, unambiguous naming helps: "Graphwick, the analytics platform" is easier to resolve than a vague pronoun or an internal nickname.
- Name the main entity in the title, H1 and first paragraph
- Make it the grammatical subject of key sentences
- Use the full, recognized name at least once
- Link to authoritative pages about related entities where helpful
Why it matters for AI search
Language models and retrieval systems connect passages to entities. If a comparison page mentions five competitors equally and your product only in the footer, a system may not associate the page with your brand at all. Clear entity focus makes it easier to retrieve the right passage for the right question.
Example
An integration page that buried its subject
Hypothetical support desk Fernwharf ran its Jira integration page through an entity analysis tool and found Jira barely registered: the copy talked mostly about "your workflow" and "the integration." Rewriting the opening to name Jira and Fernwharf directly, and describing what syncs between them, made both entities central.
Common mistakes
Chasing a score
A higher salience number from an API is not a ranking. Use it to spot pages whose subject is unclear, then fix the writing.
Questions
Google has not said so. The salience score comes from its Natural Language API. The broader point, that search systems understand entities, is well established.
