Mountain View, Calif. – Google (NASD: GOOG) has released a new extension
for its Chrome Web browser that lets users block certain Web domains from
appearing in their search results, billed as part of its efforts to detect
content farms, or "sites with shallow or low-quality content." The
Personal Blocklist extension for Chrome lets users block any sites, sending
information to Google, which will "study the resulting feedback and
explore using it as a potential ranking signal for our search results."
