Indexing Crawling
IndexNow
An open protocol that allows websites to instantly notify search engines when content is created, updated, or deleted.
IndexNow is an open-source protocol that allows websites to instantly notify participating search engines when content is created, updated, or deleted. Unlike proprietary APIs, IndexNow uses a single submission that reaches multiple search engines.
Currently supported by Bing, Yandex, and other search engines (Google has not joined), IndexNow works by submitting URLs to a simple HTTP endpoint with an API key for verification. Search engines that support the protocol share submissions among themselves.
IndexNow is particularly useful for large sites with frequent content changes, as a single API call can notify multiple search engines simultaneously, reducing the technical overhead of managing separate integrations.
Example: An e-commerce site with thousands of products implements IndexNow to notify Bing and Yandex whenever prices change, ensuring search results show current information.
In SeCoFlow: SeCoFlow supports IndexNow integration for instant search engine notification when publishing content, complementing Google Indexing API for comprehensive coverage.
