The SEO world has been scrambling to keep up with rumors of yet another “moderate” tweak to the Penguin algorithm that no one is sure of what it is exactly aimed at. Rumor of the update began spreadin through the G+ platform, but to this point no one from Google has confirmed or denied that anything is afoot. Given the timeline Google seems to follow regarding updates, they are slightly overdue for an adjustment – but an adjustment regarding what is a mystery.
The rumor, depending on source, seems to center around another attack on non-relevant links. Linking has been a problem for many webmasters since the Penguin update came to life because there is a lot of confusion over what is and is not relevant. As smart as Googlebot is, it still makes mistakes and bounces relevant links and rewards non-relevant links based on reasoning no one seems to understand.
If the latest rumor is correct, the adjustment is in regard to this problem. SEOs may see some links that previously passed through getting dinged, and some that previously got labeled as bad being removed from that list. The problem is, no one knows if there is an legitimacy to any of this or not and no one is prepared to make any pre-emptive moves until Google speaks up.
