Bing Webmaster Tools (previously the Bing Webmaster Center) is a free service as part of Microsoft's Bing search engine which allows webmasters to add their websites to the Bing index crawler, see their site's performance in Bing (clicks, impressions) and a lot more.
A web crawler collects the contents of a web page, which is then indexed by a web search engine. The search engine might make the copy accessible to users. Web crawlers that obey restrictions in robots.txt [2] or meta tags [3] by the site webmaster may not make a cached copy available to search engine users if instructed not to.
Bingbot is a web-crawling robot (type of internet bot), deployed by Microsoft October 2010 to supply Bing. [1] It collects documents from the web to build a searchable index for the Bing (search engine). It performs the same as Google's Googlebot. [2]

Page modifications are the arrival of the customers, and switch-over times are the interval between page accesses to a single Web site.
Bing defines crawl-delay as the size of a time window (from 1 to 30 seconds) during which BingBot will access a web site only once. [36] Google ignores this directive, [ 37 ] but provides an interface in its search console for webmasters, to control the Googlebot 's subsequent visits.
Search engine crawlers may look at a number of different factors when crawling a site. Not every page is indexed by search engines. The distance of pages from the root directory of a site may also be a factor in whether or not pages get crawled. [38] Mobile devices are used for the majority of Google searches. [39]
The following normalizations are described in RFC 3986 [1] to result in equivalent URIs: . Converting percent-encoded triplets to uppercase. The hexadecimal digits within a percent-encoding triplet of the URI (e.g., %3a versus %3A) are case-insensitive and therefore should be normalized to use uppercase letters for the digits A-F.
