Technical SEO & Web Infrastructure

IndexNow

Led by Microsoft Bing and Yandex, IndexNow is an open protocol through which a site pushes changed URLs and its API key after content is created, updated or deleted. This reduces reliance on periodic crawler revisits and can accelerate discovery within minutes. The source notes that Google did not officially support IndexNow as of 2024; Google’s URL Inspection workflow remains a separate route for requesting indexing attention.
