IndexNow works best as a precise change signal: it should describe URLs with meaningful new or revised content, not serve as a repeated indexing request.
Define a material update
Notify when a guide, status record, canonical or visible review date changes in substance.
Do not submit the whole site for an unchanged asset or a cosmetic adjustment.
Keep the key verifiable
Expose the configured IndexNow key file at the canonical origin and retain one consistent protocol configuration.
A valid key file helps search engines associate notices with the site owner.
Log what was submitted
Record the URL set and the content event that caused each notification.
A small audit trail supports later Bing crawl and performance analysis.
