IndexNow Sitemapper

A Python script that reads all URLs from your XML sitemap and submits them in bulk to IndexNow, allowing search engines (Bing, Yandex, and others) to immediately discover and re-crawl your updated pages.

How it works

  1. Fetches your sitemap from https://{HOST}/sitemap.xml
  2. Parses every URL, including recursing into sitemap index files
  3. Submits the full URL list to the IndexNow API in a single POST request
  4. Prints the HTTP response status with a human readable message

Requirements

  • Python 3.6+
  • No third-party dependencies — uses only the Python standard library

Usage

python3 submit_indexnow.py

Example output

Fetching sitemap: https://example.com/sitemap.xml
Found 142 URLs. Submitting to IndexNow...
IndexNow response: HTTP 200 - URL submitted successfully

Response codes

Code Meaning
200 URLs submitted successfully
202 Received — key validation pending
400 Invalid request format
403 Key not valid or key file not found
422 URLs don't belong to the host, or key schema mismatch
429 Too many requests

The script exits with a non-zero status code on any error response, making it safe to use in CI/CD pipelines or cron jobs.
