Google announced this week that it was targeting specific “low quality” sites, such as eHow. What is also interesting is that they are taking the top several dozen or so most-blocked domains from their Chrome extension and this algorithmic change addresses 84% of them, which Google claim is strong independent confirmation of the user benefits.
This is, generally, a sign that Google is becoming more proactive in targetting websites that its users don’t find useful. It also shows something we have said all along. Good quality, original, content is far better than recycled rubbish.
