The Bing URL Submission Plugin is a free utility for WordPress that automates the process of submitting URLs to the Bing index. Once configured with an API key from the Bing Webmaster portal, it seamlessly detects page updates and submits URLs automatically, ensuring that your site remains indexed with the latest content. Users can also manually submit URLs and access a list of recent submissions, enhancing control over their indexing efforts.

This plugin offers additional features such as the ability to toggle automatic submissions on or off, retry any failed submissions, and download submission lists for further analysis. However, it is important to note that the plugin does not support WordPress multisite installations. Overall, it provides a straightforward solution for keeping WordPress sites visible in Bing search results.
