Even SEOs and Webmaster owner musing systematically in recent weeks on Google algorithm but Google had already pushed out a Penguin update (or various).Google has depict Penguin as an algorithm vary that’s proposed at webspam and, more specifically, “sites that we believe are violating Google’s quality guidelines.”
Penguin led to quickly call from across the SEO industry, with lots of questioning if it made search outcomes improve or mess-up. Because its an algorithm vary, Google said it wouldn’t consider reconsideration requests made via Webmaster Central, but it did setup a form for webmasters to use if they believe Penguin had hit their sites by mistake.
