Bing has said the WordPress SEO plugin, RankMath, has adopted Bing's IndexNow protocol.

As a result, over a million WordPress sites using Rank Math can ensure their content gets indexed both faster and more efficiently. When Rank Math is installed and configured, the plugin will automatically generate and host the API Key for the IndexNow protocol on the website.

With IndexNow, any content published, updated, or deleted on the website gets submitted to the IndexNow in the background. As a result, all IndexNow-enabled search engines receive the latest changes about a site allowing for faster indexing.
