Here are the page view shares per key social media site for June 2018 for Canada, United States and global, comparing all platforms (mobile + desktop + tablet) vs. just mobile.
If you are more of the visual type, the following chart might be more helpful for you. Note that due to lack of space, I did not include all the labels in the chart below.
It appears to be safe to say that the drop in page view share for Facebook is levelling off in Canada. The drop in Facebook page view shares is still on a slight decline in the United States, but it appears as though it will level off very soon. As for global, it is still on a moderate decline. Note that the world as a whole did not experience the sharp decline that both Canada and the United States suffered right after the Cambridge Analytica scandal.
Below, you can see the progression of social media page view shares for Canada from July 2017 to June 2018. The first chart consists of all platforms (desktop, mobile, tablets) whereas the second chart looks at only mobile data.
Despite the huge drop in Facebook page view share, it is still a giant compared to all other social networks. Now is not the time to stop considering Facebook as a potential medium for reaching your clients, especially if you are targeting consumers or patients. Healthcare physicians are humans, so yes, they are also hanging out on Facebook, but there might be more efficient options to reach this audience.
The growth of Pinterest page view share seems to be levelling off as well.
Instagram, Twitter and YouTube page view shares are all on the upswing, but since they are still relatively small players, especially when compared to Facebook and Pinterest, it is difficult to see their progress without reducing the range of the chart. The charts below look only at Instagram, Twitter and YouTube page view shares in Canada, from July 2017 to June 2018, on all platforms and then on mobile. Many of the clients that I speak to are surprised to see that Instagram is still a relatively small player based on this statistics, but keep in mind that page view share does not measure how often a person visits a site or how their qualitative opinion of the site. Instagram is a player to keep an eye on, especially if you are targeting young adults.
Below are the graphs showing the progression of social media page view shares for the United States from July 2017 to June 2018. The pattern is similar to that of the Canadian charts, except that the drop in Facebook page view shares does not seem to have stopped quite yet.
