meizitang The original algorithm update was launched in April 2012 and was refreshed twice within the same year. Its primary purpose was to reduce Web spam and to penalize websites with unnatural link profiles. The update was designed to identify websites that managed to appear at the top of search engine results pages despite having poor quality and little value to provide Internet users.
According to the search engine's software and Web spam expert, "about 2.3% of English-US queries are affected to the degree that a regular user might notice." Early evaluations from software companies reveal that gaming sites, adult sites, and even the websites of certain well-known organizations appear to have been affected the most by the newest update.
"The good news is, weĦŻve gone and analyzed the big cross-section of our own customers, and in the majority of cases, our customer rankings have increased," Schramko shares. "And I feel that is because a lot of the bad sites using very bad 'spammy' networks have been filtered out a little bit harder."
