# IndexNow Submit

Check your IndexNow key file, then send your sitemap to Bing, Yandex and 4 more engines. It is free, with no sign-up and no key.

Also known as: IndexNow Submitter, IndexNow Sitemap Submitter, IndexNow Key Checker, Bing URL Submit.

## What it does

IndexNow Submit sends the URLs in your sitemap to every IndexNow search engine and shows each engine's own answer: Microsoft Bing, Yandex, Seznam.cz, Naver, Yep, Amazonbot.

It works only for a site whose IndexNow key file is live and holds exactly the key. The file is read before anything is sent, and a wrong or missing file stops the submit with the exact fix (a 404, an HTML page served in its place, the wrong text, a redirect to another host).

The check reads robots.txt for the sitemap, follows a sitemap index into its children, unpacks gzip, and says which URLs would be sent and why the others are left out: another host such as www, outside the key file's folder, duplicates or too long. It flags tracking parameters and http addresses. changed_since sends only pages whose lastmod moved, and when more than 10,000 qualify the newest go first and batch 2, 3 and on send the rest.

No key yet? The check makes one and gives the file to publish. Free, no sign-up, nothing stored; one submit per site every 60 seconds, and the same batch once every 5 minutes. Accepted means received, not indexed. Google does not use IndexNow. A page at https://tools.openkrill.app/indexnow does the same for people.

- Submits sitemap URLs to 6 IndexNow engines and returns each engine's status and meaning
- Refuses to submit until the site's key file is live and holds exactly the key
- Explains a broken key file: 404, an HTML page in its place, wrong text, a redirect to another host
- Finds the sitemap in robots.txt, follows sitemap indexes and reads gzip sitemaps
- Shows which URLs are left out and why: other host such as www, outside the key folder, duplicates
- Sends only pages changed since a date, newest first, 10,000 per submit in batches
- Makes a new IndexNow key and gives the exact file to publish
