Earlier this month Google rolled out its new core update officially named ‘June 2019 Core Update’. However Google actually announced this update the day before it was rolled out which is something they’ve never done before, normally you find out after it has been completed (I guess they wanted to prepare us).
When Google updates the algorithm it can have an impact on your website which can be positive or negative. It’s possible that you might have moved up the rankings but you also might have moved down, therefore losing traffic and visitors. It’s important to check your Google Analytics to see if the algorithm has negatively affected your website as there are changes that you would need to make. If you log into analytics look at the traffic from the date of the update compared to the previous month you will be able to assess the impact, in this case it was started on June 3rd and completed by June 8th so they’re the dates you would want to analyse.
