Crawling and index eligibility are separate gates
A page can be accessible to a crawler and still be unsuitable for indexing. Check the two conditions separately. Seeing a successful response does not establish whether the canonical destination and indexing instructions agree.
A successful page response establishes accessibility under the tested conditions. It does not resolve indexing instructions, canonical selection or content suitability. Conversely, blocking a crawler can prevent it from seeing a page-level instruction that you intended it to process.
A worked example
In a hypothetical launch, an article returns HTTP 200 but retains a staging noindex directive. Opening it in a browser looks normal. A separate technical inspection identifies the directive. Another page returns a server error and requires an availability repair instead; removing noindex would not fix that failure.
How to apply it
- Inspect the final response and whether the intended crawler can fetch it.
- Review rendered robots instructions and the declared canonical destination.
- Use the authorized search inspection evidence to distinguish eligibility from actual index inclusion.
What the result can establish
Report fetchability, intended indexing and observed inclusion separately. After a repair, request appropriate discovery and monitor the search platform’s feedback. Technical eligibility does not guarantee inclusion or a position for a commercially relevant query.
