Google Changes Algorithm To Penalize Site Scrapers

Bookmark and Share
Google updated its search algorithm this week to help reduce webspam in its search results. These changes were made in response to increased criticism of Google and its Search Engine Results. The criticism has been partly inspired by the emergence of newer forms of webspam alongside traditional webspam.

The latest webspam outbreaks commonly come from content farms and sites that syndicate content. Earlier this month, Stack Overflow's Jeff Atwoodpointed out that in the last year, some content syndicators have routinely began outranking Stack Overflow on Google. In other words, the syndicates are outranking the originals.

In Stack Overflow's case, the problem was bad enough that a community member built a Google Chrome Extension designed to redirect to Stack Overflow from spammier syndicates.
