It has been confirmed that there was an update to Google’s core search algorithm yesterday. According to a statement from Google that they sent to searchengineland.com,” This is not a Panda update. As you know, we’re always making improvements to our search algorithms and the web is constantly evolving. We’re going to continue to work on improvements across the board.”
The SEO world has been trying to get more details on what this change will affect specifically but has had no luck. So from what we know, this was not Panda, not HTTPS and also not Penguin, it was just a normal Google core search update where Google won’t give us any details on. If you’ve noticed any search ranking changes, it may be attributed to this.
This is not to be confused with the Panda Update that will be coming in a couple weeks.
