It's been said that most people can't tell the difference between influencer posts and advertisements.

A study conducted by Open Influence explains how people who frequent social media websites actually view influencer advertisements. It shows that about 514 adult Americans who visit social media websites were asked questions that could help marketers strategize.

When these adults were asked which social media websites they frequented the most, the following percentages were provided:
Facebook-73.7 percent
Instagram-38.1 percent
YouTube- 32.5 percent
As you can see, Facebook was a clear front runner.
