Widespread Ranking Drops for Strong, White Hat sites

[OneClickVentures]

Hi Moz,

A few of our sites experienced widespread ranking drops across all keywords this morning.  Both of these are very strong sites with a high DA (56), moz rank and moz trust above 5. We haven't been doing any black hat SEO, creating spammy links, or paying for links. Is anyone else seeing anything similar or have any ideas as to what type of Algorithm update this might be? We currently rank 67th for our name.

Hi,

There were recently quite a few major changes that affect the way the algorithm looks at common SEO tatctics meant to manipulate rankings, no matter the color of "hat" used.

My personal suggestion to you would be to keep pressing on, creating great quality content on your site - sharing that content in the Social realm - and trying to distribute great quality content to related blog sites.

Keeping in mind the need for a natural portfolio of not only anchor text links, but standard URL links and Brand Links.

Overnight we dropped completely off the rankings.  I have no idea what happened.  I was excited we were doing so well the past 60 days and ranked for many keywords and long tails.   This morning we disappeared from 100% of the rankings.
