Google (NASDAQ:GOOG) has launched yet another update to its web search algorithm, which is expected to improve search result quality by detecting and penalizing search result spammers in a better way. The new update will decrease search rankings for sites that violate Google’s quality guidelines and use forbidden techniques like keyword stuffing, link schemes, cloaking and duplicate content to bump up their page rankings. 
While Google has been trying to detect and reverse the impact of such blackhat SEO techniques for years, the new update significantly improves its ability to do so. Once the update rolls out, Google expects to see much better search results for certain sets of queries. Google has stated that the new update will impact and improve around 3.1 percent of English queries, and possibly more in other languages.
