Over the course of the last 24 to 48 hours, some chatter have been noticed among the SEO communities and also in the black hat space. The chatter is regarding a Google search ranking algorithm update that supposedly touched down within the last couple of days.
Some have mentioned that the medic update downfalls have been reversed while other have said that they are not sure if that reversal was related to an update. This is all still new and majority of the tracking tools have shown almost no changes over the past days. Some of the tools have shown some changes but most tools have not.
The chatter is nothing major and it has not reached the levels of a large update but it is still more chatter than usual. Maybe it is just a minor change or maybe it is a small and more targeted update or maybe it is just nothing. It is difficult to say anything this early.
