If you don’t monitor your clients, your own and your competitors search engine results you might not notice the changes. Earlier this week, Matt Cutts from Google announced they would be launching a new on-page spam detection system with the intention to reduce the amount of spam we see in Google.

Matt Cutts confirmed the rumors and Search Engine Land reported that the algorithm is in fact live.

What can you expect?

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. – Matt Cutts
