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.
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. Search engine cache can be used for crime investigation, [4] legal proceedings [5] and journalism.
The concepts of topical and focused crawling were first introduced by Filippo Menczer [20] [21] and by Soumen Chakrabarti et al.

Indexing low priority to high margin to labels like strong and link to optimize the order of priority if those labels are at the beginning of the text could not prove to be relevant. Some indexers like Google and Bing ensure that the search engine does not take the large texts as relevant source due to strong type system compatibility. [23]
In addition, the Yahoo and Bing search engines also respect this attribute value. [ 6 ] On June 15, 2009, Google software engineer Matt Cutts announced on his blog that GoogleBot changed the way it treats nofollowed links, in order to prevent webmasters from using nofollow for PageRank sculpting.
