IndexNow API Key Generator

What is this tool?

This IndexNow key generator creates a random hexadecimal API key for IndexNow setup. IndexNow lets a site notify participating search engines when URLs are created, updated, or deleted, reducing the wait for recrawling.

The key proves that update notifications are authorized by the site owner. In a typical setup, the key is hosted in a key file on the domain and also included in URL notification requests.

Use this tool when enabling IndexNow in a CMS, deployment pipeline, sitemap workflow, or custom publishing script. The generated value is only one part of setup; the hosted key file and notification endpoint still need to match IndexNow requirements.

How to use

1. Choose a key length or keep the default length.
2. Click Generate to create a random hexadecimal key.
3. Copy the key and use the displayed filename hint when setting up the key file.
4. Use the same key in IndexNow update requests for your site.
