I have added bing script code and submitted Sitemap as well, but bing not crawl my website automatically. Why any tips to update my website through bing?
did you get any error messages, it is strange, you must consult one of the bing staff or simply join their forum discussion and put your issue over there, you will definitely be treated well enough to get a solution.
Check the server header of your website, Is it is found 200 Ok, if not, then sort out this issue and resubmit the website and XML sitemap in Bing Webmaster tool.
