Bing has quietly rolled out the new sitemap index coverage report in Bing Webmaster Tools and today posted a how-to on that reporting tool. I believe the new sitemap index coverage report began rolling out in late June 2023 and pushed it to everyone a few weeks ago but Bing has never formally announced the new report. Per sitemaps index file, a listing of all the sitemaps included and the issues detected if any. Bing now reports a breakdown of URLs indexing status for URLs indexed and URLs which need attention from sitemaps and sitemap index files. This report can help you improve your index rate by Bing Search and thus improve your traffic from Bing Search.
