wikipedia org wiki blekko blekko from wikipedia the free encyclopedia jump to navigation jump to search web search engine blekko com blekko home page type of site search engine available in english owner ibm international business machines url www blekko com launched november 1 2010 current status defunct march 27 2015 blekko trademarked as blekko lowercase 1 was a company that provided a web search engine with the stated goal of providing better search results than those offered by google search with results gathered from a set of 3 billion trusted webpages and excluding such sites as content farms the company s site launched to the public on november 1 2010 used slashtags to provide results for common searches blekko also offered a downloadable search bar it was acquired by ibm in march 2015 and the service was discontinued contents 1 development 1 1 acquisition and closure 2 slashtags 3 features 4 toolbar 5 reception 6 references 7 external links development edit the company was co founded in 2007 by rich skrenta who had created newhoo which was acquired by netscape and renamed as the open directory project 2 blekko raised 24 million in venture capital from such individuals as netscape founder marc andreessen and ron conway as well as from u s venture partners and cmea capital 3 the company s goal was to be able to provide useful search results without the extraneous links often provided by google individuals who enter searches for such frequently searched categories as cars finance health and hotels received results prescreened by blekko editors who used what the new york times described as wikipedia style policing to weed out pages created by content farms and focus on results from professionals 4 use of slashtags restricted the set of search results to those matching the specified characteristic and a slashtag was to be automatically added for search categories with prescreened results 5 this use of slashtag is also implemented in the access of videos and images because blekko did not have the option to search specific databases for these contents 6 queries related to personal health were limited to a prescreened list of sites that blekko editors had determined to be trustworthy excluding many sites that rank highly in google searches 2 as of blekko s launch date its 8 000 beta editors had developed 3 000 slashtags corresponding to the site s most frequent searches 5 the company hoped to use editors to develop prepared lists of the 50 sites that best match its 100 000 most frequent search targets 2 additional tools allowed users to see the ip address that a website is running on and let registered users label a site as spam 7 blekko also differentiated itself by offering richer data than its competitors for instance if a user accessed a domain name with the added seo he would be directed to a page containing the statistics of the url 8 this is the reason experts cited blekko s fitness with the big data paradigm since it gathers multiple data sets and presents them visually so that the user is provided with quick meaningful and actionable information 9 at the time blekko announced plans to earn revenue by selling ads based on slashtags and search results the company also planned to provide data on its algorithm for ranking search results including details for inbound links to specific sites 4 as part of a permanent post in blekko s help section was the following web search bill of rights 10 search shall be open search results shall involve people ranking data shall not be kept secret web data shall be readily available there is no one size fits all for search advanced search shall be accessible search engine tools shall be open to all search and community go hand in hand spam does not belong in search results privacy of searchers shall not be violated one writer referred to the bill of rights as what we assume is a poke at google 11 12 in 2011 blekko announced blocking content farmy sites to reduce spam in line with its bill of rights 13 in may 2012 mozilla announced an instant search browser plugin for firefox designed to cache repetitive search requests in partnership with blekko 14 in august 2012 blekko put all its seo statistics behind a paywall 15 despite previously declaring that ranking data shall not be kept secret 12 in its bill of rights 15 acquisition and closure edit ibm bought blekko and closed the search service on 27 march 2015 redirecting searches to a page announcing the blekko technology and team have joined ibm watson and linking to a blog post announcing that the blekko service was closed with blekko s web crawling abilities to be integrated into ibm watson adding advanced web crawling categorization and intelligent filtering technology 16 slashtags edit blekko used an initiative called slashtags 1 consisting of a text tag preceded by a slash character to allow ease of searching and categorise searches system and pre defined slashtags allowed users to start searching right away users could create slashtags after signup to perform custom sorted searches and to reduce spam 4 features edit the following features were available to all users search engine optimization statistics from 2012 subject to payment 15 linking pages in and out statistics ip address lookup cached pages tagging of pages finding duplicate content comparing sites crawl statistics page count location of robots txt cohosted sites page latency page length toolbar edit blekko offered a downloadable browser toolbar or search bar which changes default search and home page urls of the user s web browsers 17 reception edit in 2010 john dvorak described the site as adding so much weird dimensionality to search and recommended it as the best out of the chute new engine i ve seen in the last 10 years 7 in matthew rogers review of the site he found it slow and cumbersome and stated that he did not understand the necessity or utility for slashtags 18 in his pcmag com review jeffrey l wilson expressed approval of some search results but criticized the site s social features which bog down the search experience 19 references edit a b about blekko com
