Free IndexNow Submission to Bing and IndexNow
IndexNow is an open protocol that lets websites tell participating search engines, including Microsoft Bing, that a URL was added or changed. MassPinger sends your URL list to www.bing.com/indexnow and api.indexnow.org and shows each endpoint's response.
Using your own IndexNow key
For your own domain, host a key file at https://yourdomain/<key>.txt and enter that key. IndexNow endpoints verify the key against your host before accepting the URLs.
Reading the result
HTTP 200 means submitted, HTTP 202 means accepted for processing (key check pending), and 4xx usually means the key file or host does not match.
