Google is engaged in a constant, uphill battle against those who try to game the SERPs for profit, distorting search results with spammy tactics and questionable link acquisition. In 2012, the first Penguin update was implemented to deal with sites that were using unnatural links to boost their search engine ranks.
As a result of the original Penguin, several websites were penalized, which ultimately removed them from visibility in the SERPs. It took some sites quite a bit of time to recover, and sites that made legitimate attempts to restore their rank in the search results were forced to wait for the next update of the algorithm. Now, everything has changed with Penguin 4.0.
"Historically, the list of sites affected by Penguin was periodically refreshed at the same time. Now Penguin is real-time, so changes will be visible much faster, typically taking effect shortly after we recrawl and reindex a page," wrote Gary Illyes on the Google Webmaster blog. |
