Therefore, it was defined as the google medic algorithm update. 

many industries like technology, business, and legal had also looked out on the backwash of the medic update. Google rejected the fact that they were clearly targeting these niches or industries.  The content from these industries can have huge consequences on the user’s lifestyle be it business, money, health, or relationship-wise.
