Microsoft's search engine Bing ended support for sitemap pings Aimy Sitemap uses to send notifications (read the official blog post).
To follow the recommendation, we already published a new plugin Aimy IndexNow.
Right now we are working as fast as we can to integrate notifications to indexnow.org in the sitemap workflow as well.
Our new extension that implements IndexNow for your Joomla! content is online.
IndexNow is a protocol to notify search engines about new or updated content of your website. It is supported by several search engines, for example Bing and Yandex.
