Recently, Google announced that Panda is now part of the core algorithm and runs in real time. However, it was being observed that it doesn’t take effect in real time. Now at the SMX Advanced conference, it was made clear by Gary Illyes that Panda fundamentally still works in the same way as it always has, and takes months to roll out once it has assigned/refreshed a score to your website.
