After 2 years waiting, Google has officially confirmed on the Google webmaster blog that Google Penguin 4.0 - The Real Time Penguin Algorithm is rolling out in all languages.
The last update in 2014 – Penguin 3.0 – may have only affected less than 1% of US/UK searches, but that ultimately translated to 12 billion queries.
Google will no longer confirm Penguin update
Google also said with this update, it will no longer confirm future Penguin updates. That makes sense. Since it’s a constant process, there’s nothing to confirm.
Is Penguin fully live?
This real-time Penguin update is probably not fully live yet. It is now “rolling out,” Google said. Google didn’t tell us how long it may take to roll out, but I suspect it won’t take that long, maybe a couple of weeks. If Google regularly revisits your pages, then you should likely see the change quickly. If Google comes to your site more infrequently, it may take longer.
