Submit URLs to Bing
Bing recommends webmasters using the Submit URLs to get their web content indexed as soon as they published or updated it online. Webmasters can Submit URLs to Bing programmatically through the Submit URL API or using the Submit URLs feature in the Configure My Site section in Bing Webmaster Tools. The feature allows Webmasters to submit up to 10,000 URLs per day for most sites, for potential immediate crawl and indexation depending on a variety of signals available to Bing. If you think the quota provided is not enough, you can proactively request quota increment by creating a support ticket. We will review your request and update your quota accordingly. Bing also recommends webmasters to have Sitemaps refreshed at least once a day, to help Bing discovering all relevant fresh and non-fresh URLs of their web sites.
Submit URLs through Bing Webmaster Tools
To submit URLs using the Submit URL feature, simply add 1 URL per line and click Submit. The URLs are immediately evaluated for search indexation and when quality criteria are met, they will begin to surface in Bing search. This is very useful in helping get important content indexed quickly.
The number of submissions on a day and the remaining quota for a site can be checked in the Submit URL feature. The list of submitted URLs in the page will show the latest 1000 URLs submitted by the webmaster.
The Submit URLs feature in Webmaster Tools is currently restricted to root domains only and will not accept the submission of subdomains. If there are sites mapped to sub-domain then quota is allocated at domain level and not at sub-domain level.
Submit URLs through Bing Webmaster APIs
Webmasters can also use Submit URL API offered as part of Bing Webmaster API.
For sites that are trying to submit large number of URLs to Bing, using the Batch URL submission API is recommended.
Programmatically getting the remaining quota is also possible through the Get URL Submission Quota API.
