Entity rich content means that the content has many meaningful sentences that refer to specific things rather than being wordy fluff.
There was a trend in SEO for a while where people were trying their best to produce longer and longer content by either repeating a concept with a different wording or by making the content unnecessarily wordy in other ways.
That doesn’t work because Google analyzes the language in the document and breaks it down by entities.
The tactic changed when Google revealed BERT, their machine learning algorithm.
>How do you establish relation between **entities**?
Google understands natural language, you establish relationships between entities by explaining it in words.
Example: **John D. Benjamin** is the **author** of a **book** *named* **”How I Defeated Chronic Swamp Ass.”**
