Once Bing verifies the site ownership, it provides the Bing Webmaster Search Console for similar submissions and reports as the Google Search Console.

Your website will receive a good amount of traffic from Yahoo after submitting your website to the Bing Search Engine.
Submitting Your Website to Baidu :
Baidu is the biggest and most popular search engine in China. Baidu search engine allows you to submit your site to its search engine.
