In short
The useful difference a page adds compared with other pages already covering the same query.
Search systems and readers reward content that contributes a sharper answer, original evidence, a better example, or a decision framework instead of repeating the same generic explanation.
Where it bites
Information gain matters when visibility depends on how machines read, cite, and summarise your pages. It rewards clear structure more than louder marketing language.
What to check
- Is the definition explicit enough to be cited?
- Does the page answer the buyer question directly?
- Is the source structure machine-readable?
