Google employee Matt Cutts announced in his earlier this week the search giant is considering a new, on-page spam detection technique to reduce spam content – meaning copied or scraped – from appearing in Google Search results. Today however, Cutts released an update in his blog and confirmed the news that this algorithm was already launched earlier this week.

“This was a pretty targeted launch: slightly over 2% of queries change in some way, but less than half a percent of search results change enough that someone might really notice. The net effect is that searchers are more likely to see the sites that wrote the original content rather than a site that scraped or copied the original site’s content.”

Sources indicate that according to data gathered from Webmasters, the algorithm which was approved at a weekly Google quality launch meeting in Thursday was rolled out on January 26^th and 27^th.

Based on Cutts’ announcement, Google is indeed making efforts to remove spam from its SERPs, namely SEO-purposed plagiarized content copied or scraped from viable sites. SiliconANGLE was there to give its take on Cutts’ initial blog post concerning this matter, as well as other news from the spam and security arenas.
