Yesterday Google Confirms Core Search Ranking Update Took Place But Not Penguin Related. What is it, any idea please? Is there any effect on site ranking & traffic?
Yes Google Panda is now part of Google's core algorithm. But I am not sure that last one is about the ranking update or any other.... for your reference you can check the Google Webmaster report 2016 here https://www.seroundtable.com/july-2016-google-webmaster-report-22342.html
