What it means
After crawling, the search engine analyses the page and decides whether to store it as a distinct answer to user queries.
Term in plain language
Indexing
Adding a processed page to the search-engine database used to build search results.
Why it matters
An accessible URL is not necessarily indexed: directives, duplication, weak content or another canonical version may prevent inclusion.
Example
A new article returns 200, allows crawling and later enters the index under its canonical URL.
