# IndexNow key generator

Make an IndexNow key and its key file in your browser, see where it goes, and test it with one URL. Free, no sign-up.

This generator needs JavaScript. Without it, any string of 8 to 128 letters, digits and dashes is a valid key; the steps below still apply.

The key is made in your browser with `crypto.getRandomValues`. It is not sent to mowteng or anyone else, so nobody else knows it until you publish the file.

## How the key file works

1. **Download the file.** It is named after the key and contains only the key, which is what the IndexNow protocol checks.

2. **Upload it to your site's root.** It must open at `https://your-site/<key>.txt` and return the key as plain text. On most static hosts, put it in the folder that becomes the site root, such as `public/`.

3. **Submit a URL.** Open the test URL above, or send changed URLs from your assistant. Participating engines (Bing, Yandex, Seznam, Naver, Yep and others) share every submission. Google does not take part.

## Reading the response

- **200 or 202:** accepted. 202 means the key file has not been checked yet.

- **403:** the key is not valid: the file is missing, or its contents differ from the key.

- **422:** a URL does not belong to the site, or the key does not match it.

- **429:** too many requests. Submit only pages that were added, changed or removed.

A 200 tells engines to look. It does not mean the page will be indexed.

## Or let your assistant do all of it

With mowteng connected, `indexnow_setup` makes a key for your site, gives you the file and says where it goes, then checks that it is live. After that, `indexnow_submit` sends changed URLs without you passing the key, and asks before it sends.

> **Ask your assistant:** Set up IndexNow for example.com, then tell all IndexNow engines about the pages I changed today.

If you already made a key here or in an SEO plugin, your assistant can pass that key instead. The [IndexNow setup guide](https://mowteng.app/guides/set-up-indexnow) covers the details.
