The document discusses Google's rollout of the Penguin 3 algorithm update, which aims to demote websites with low-quality or manipulative link profiles. It provides details on the update's worldwide scope and timeframe. The effects are explained as demoting sites with bad link profiles, such as those with many links from irrelevant, thin, or spammy sites. Actions are recommended for websites affected by Penguin 3, such as checking for an over-optimized anchor text ratio, keyword stuffing, or drops in traffic since mid-October, and taking steps to disavow bad links and build more natural, relevant links.
