Your SI is a unique tracking code Google assigned to you. When you share a link to a youtube video, Google puts your SI in the link, even though it doesn’t serve a purpose in helping people reach the video. What it does do, when you visit a link with someone else’s SI, is tell Google that you followed a link shared by this other person. This lets Google see who you’ve been talking to on other platforms, and track your relationships and social movement patterns.
You left your SI in the link
