Hello,
I’m sorry to hear that you are facing a 429 error while trying to submit URLs using the IndexNow API. The 429 error means "Too Many Requests," indicating 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 to the IndexNow API for a while and disable the automatic submission feature. You can do this by deselecting the auto-submission option in the Rank Math SEO settings. Here’s how you can do it:
- 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.

By following these steps, you can prevent automatic submissions and reduce the number of requests to the IndexNow API, helping you avoid the 429 error.
If you need further assistance or have any questions, feel free to reach out to our dedicated support team here. We are available 24/7 to assist you. Thank you for reaching out, and we hope this helps resolve your issue.

How to Fix 429 Error with IndexNow API » Rank Math
Hello,
Thank you for contacting Rank Math support, and sorry for any inconvenience that might have been caused due to that.
For some initial troubleshooting, you can change the API key and clear your website cache. Then wait for a few hours and try submitting another URL again.
Meanwhile, please confirm if your site is hosted on a shared IP hosting. The 429 response comes from the IndexNow API and has nothing to do with our plugin. It is a common issue with websites hosted on shared hosting. You can confirm that by using the official plugin of Bing for IndexNow: https://wordpress.org/plugins/indexnow/
The official plugin will also return the same response code. There is nothing we can do from our end to fix this. Let us know if the official plugin works.
Let us know how it goes. Looking forward to helping you.
Thank you.
