Matt Cutts, a Google software engineer and head of Google’s Webspam team, recently gave an update in his blog on his search engine spam post.
A recent post of his stated that “we’re evaluating multiple changes that should help drive spam levels even lower, including one change that primarily affects sites that copy others’ content and sites with low levels of original content.” This change was launched earlier last week.
Cutts went on to explain the launch was targeted, in that just a little over 2% of queries change in some way, but less than half a percent of search results change enough that someone might actually be aware of it. As a result, searchers are more likely to see sites that wrote the original content, versus a site that scraped or copied the original site?s content
