After implementing IndexNow, you observe no change in Bing's indexing of updated pages. What is the most crucial aspect of your server's configuration to examine?

The most crucial aspect of your server's configuration to examine is whether your server is correctly receiving and processing the POST requests sent by your system when using IndexNow. IndexNow is a protocol that allows websites to instantly inform search engines like Bing about content changes, triggering a recrawl. When content is updated, your system sends a POST request to Bing's IndexNow endpoint, notifying them of the change. If your server is not configured to properly handle these POST requests, Bing will not receive the notifications, and your pages won't be re-indexed. This could be due to a firewall blocking POST requests to the specific IndexNow endpoint, incorrect server-side scripting that fails to process the incoming data, or misconfigured routing that prevents the requests from reaching the intended destination. You need to verify that your server logs show successful reception and processing of the POST requests from your system to Bing's IndexNow endpoint. A common issue is a server firewall blocking requests from outside IP addresses, which would prevent your IndexNow notifications from reaching Bing.
