My firm has a large collection of websites. We also have a highly-effective (at least for now) black hat SEO technique. We have never been slapped or received any warning messages from Google. Our method does not work via link building or involve content, though we will be optimizing the on-page content and architecture on it's own. While Google appears oblivious to our method of "SEO" (It's not really SEO as traditionally understood, but results in the same effect - first page ranking), it is quite likely they shall "notice" us in the future, especially if we trip some sort of warning by ranking too well, too quickly. In order to avoid catastrophe (Google flagging one of our sites then subjecting all other sites to the same level of scrutiny), we have instituted a number of pre-preemptive actions to "disassociate" our websites. I am willing to post what we have done here, but would first like to hear from other BHW members what they have done along similar lines. My goal in posting here is to uncover any important precautions that we might have missed. Specific technical concerns: 1) How to best attempt to detect any flagging/penalization/undue-attention by Google or Bing 2) How to individually disassociate a collection of sites, so as to avoid the flagging of any one site causing negative repercussions to spill over onto other sites owned/worked on. Looking forward to actionable comments or links to other related posts or resources.
