We’ve been exploring different algorithms to detect content farms, which are sites with shallow or low-quality content. One of the signals we’re exploring is explicit feedback from users. To that end, today we’re launching an early, experimental Chrome extension so people can block sites from their web search results. If installed, the extension also sends blocked site information to Google, and we will study the resulting feedback and explore using it as a potential ranking signal for our search results.
Maybe Google needs to be a little less automated and a little more human?
My suggestion would be for Google to get more customizable. I know I can do filters and searches within the search box, but that’s a pain every time I want to do a search. Why can’t I just tell Google, “Never show me results from about.com, ehow.com, etc.”? A simple blacklist feature in my account settings can go a long way.
