Profile photo
A profile photo is the image displayed on your LinkedIn profile, contributing to your first impression. A professional and approachable profile photo can increase profile views and build trust. It is recommended that your profile photo looks like you and feels like you. Show up on your profile as you show up in real life.
Shield doesn't track your profile photo or how much people click on it to see a bigger version. Would be cool but the data is simply not available on LinkedIn. Shield does track other profile performance metrics like post activity, profile views and network growth across followers and connections.
