What is the ruling on earning from Google AdSense, knowing that the ads shown to the browser are based on their interests, so forbidden ads may appear to those who seek them?

The fact that advertisements appear according to the user's interests does not affect the ruling. What matters is their ability to control them by filtering out and preventing the display of what is not permissible. Missing control over one or two advertisements does not cause harm. If something impermissible to see appears, let them delete it and lower their gaze, for the Prophet, peace and blessings be upon him, said to Ali: "O Ali, do not follow a glance with another glance, for you are allowed the first, but not the second."
