Hello,
We apologize for the issue you are facing with submitting URLs in IndexNow and receiving a 429 response code (Too Many Requests). This error indicates that your IP address has sent too many requests to the IndexNow API within a short period.
To resolve this issue, you should stop submitting your URLs for a while and consider disabling the automatic submission feature in Rank Math. Here’s how you can do that:
Disable Auto-Submission
- Navigate to Rank Math SEO → Instant Indexing → Settings from your WordPress dashboard.
- In the Auto-Submit Post Types setting, click the Select / Deselect All button until the Posts, Media, and Pages options are unchecked.

Submit URLs Manually in Batch
Once you have addressed the 429 error, you can manually submit your URLs in batch by following these steps:
- Go to Rank Math SEO → Instant Indexing → Submit URLs.
- Add multiple URLs (one per line) of your blog posts, home page, or any other web content.
- Click the Submit URLs button to submit all the added URLs for indexing without visiting webmaster tools or configuring it with an API key.

If you continue to experience issues, please reply to this ticket with your site URL so that a human agent can assist you further. Thank you for raising this concern!
