Microsoft unveiled their new search engine Bing,<\/em> last week with considerable fanfare. \u00a0Thanks to Google’s Wave announcement the same day it probably didn’t get as much press coverage as it deserved. Bing replaces Live Search and MSN Search.\u00a0 Initial reviews \u00a0have been quite positive. Billed as a “Decision Engin<\/em>e”, Bing on the desktop has some nice touches including auto completion of queries, a list of related searches \u00a0in the left sidebar and \u00a0infinitely scrolling results rather than pagination for \u00a0image searches. \u00a0Bing also does a nice job with shopping searches, presenting results in a grid similar to price comparison sites like Price Grabber. There’s one-click integration with\u00a0Bing (formerly Live) Cashback which gives discounts on products purchased through the site. \u00a0Results can be filtered by brand and price and sorted by price, shipping cost and cashback percentage. The relevance of search result’s is pretty good too, I didn’t get any of the wacky off-topic results that used to plague MS Live search. \u00a0Bing is a real improvement over Microsoft’s previous search products. I generally found \u00a0Live .com to be inferior to both Google and Yahoo search. \u00a0With Bing, I think Microsoft has leaped past Yahoo to rival Google in both relevance and features.<\/p>\n But that’s on the desktop. \u00a0What about the mobile version of Bing (m.bing.com)<\/strong>? \u00a0Frankly I was disappointed by mobile Bing. \u00a0The good news is that the improved relevance seems to carry over to the mobile version. The related search feature also made it to mobile and works well. Bing’s local search,\u00a0which was one of Live Mobile’s strong points,\u00a0has click to call numbers, user reviews, good maps and directions. It’s one of the best ways to find nearby shops and attractions with your phone.<\/p>\n But \u00a0product search on mobile \u00a0is full of problems.<\/strong> Results can be filtered by price and brand but can’t be sorted and the default sort seems to be random. For some products there is a “From $N.NN” \u00a0link which, when it works, brings up a list of \u00a0vendors for that product sorted by price. \u00a0However, the price link often brought up the message “You’re trying to perform a search that isn’t supported in your country. Please try a different search.<\/em>” or displayed an XML parsing error in Opera Mini and Firefox. Clicking a vendor name link, which looks like it might let you make a purchase,\u00a0invariably failed with a variety of different error messages.<\/p>\n The worst thing about Bing mobile is that it seems to be almost completely unaware of \u00a0the existence of mobile optimized web sites<\/strong>. \u00a0Mobile sites are getting indexed and do occasionally occur in the results, usually buried a page or two down. \u00a0But they aren’t consistently flagged as mobile\u00a0and following a link to a mobile site often opens it in the Infogin transcoder rather directly. \u00a0For example, a search for “wapreview” returns a transcoded version of wapreview.com as its top result. \u00a0Wapreview.mobi appears as the ninth result and also opens in the transcoder. \u00a0This is in spite of wapreview.com having a\u00a0<link rel<\/span>=’alternate<\/span>‘ \u00a0media<\/span>=’handheld<\/span>‘ …> meta tag pointing at wapreview.mobi.\u00a0That meta tag \u00a0is the defacto standard for telling search engines about the presence and location of mobile specific content.<\/p>\n The reformatting of wapreview.mobi \u00a0is both unnecessary and ugly. According to both Wurfl’s “Rules for Responsible Reformatting<\/a>” and the W3C’s Content Transformation Guidelines<\/a>,\u00a0wapreview.mobi should not have been \u00a0transcoded as it’s 1) a .mobi domain, \u00a02) is written in xhtml-mp and 3) is sent with a Cache-Control no-transform header. Any one of which alone should tell a compliant transcoder to leave the site alone.<\/p>\n The Bing transcoder is further out of compliance<\/strong> with both the W3C and Wurfl Rules because it spoofs the User-Agent header to \u00a0represent itself as IE6, and doesn’t send the original user agent in an alternate header. \u00a0This transcoder can be detected by the following headers:<\/p>\n User-Agent:\u00a0Mozilla\/4.0 (compatible; MSIE 6.0; Windows NT 5.2; SV1; .NET CLR 1.1.4322)<\/p>\n Via:\u00a01.1 WTRSCP19911<\/p>\n It is possible to turn off the transcoder on Bing Mobile’s Settings <\/em>page and there is a link to the original at the bottom of each transcoded page but the default is for the transcoder to be on.<\/p>\n It’s not just WapReview that gets its mobile site buried or broken by Bing Mobile. It also happens to CBS News, Google News, The <\/em>Huffington<\/em> Post, <\/em>Gizmodo<\/em>, Sports Illustrated, Slashdot<\/em> and countless other sites that have mobile versions. \u00a0These publisher’s mobile sites aren’t easily discoverable with Bing and when they do appear in results they are bowdlerized by unnecessary transcoding. \u00a0In contrast both Google and Yahoo’s mobile searches are much more mobile aware with the option to filter results to mobile web only and with obvious mobile content rarely if ever transcoded. I certainly hope compliance with mobile search and transcoding standards was something that broke in the rush to release Ping rather than by design.<\/p>\n I know that the Infogin transcoder has \u00a0heuristics based the Responsible Reformatting and W3C criteria\u00a0to detect mobile sites\u00a0and pass them through unaltered but it appears that the heuristics are either disabled or not working properly.<\/p>\n The mobile discoverability problem \u00a0will probably be harder for Microsoft to fix the inappropriate transcoding of mobile sites. \u00a0The Bing crawler needs detect and follow\u00a0link\u00a0rel<\/span>=’alternate<\/span>‘ \u00a0media<\/span>=’handheld<\/span>‘ \u00a0meta tags and do a better job of recognizing \u00a0mobile formatted content and tagging it as such. \u00a0Eventually I’d like to see Bing add a “mobile web” category or filter for search results like Yahoo and Google do. \u00a0Transcoding is a crutch that should be \u00a0reserved for content that is not published in a mobile optimized form.<\/p>\n","protected":false},"excerpt":{"rendered":" Microsoft unveiled their new search engine Bing, last week with considerable fanfare. \u00a0Thanks to Google’s Wave announcement the same day it probably didn’t get as much press coverage as it deserved.
