Why isn't my website tracking visitor views correctly?

Hello

Since I launched my website even if I know someone went on the website (friends/family/social media), the numbers of views remain at 0 or these persons do not appear (e.g no one in France when I know they are in France)

Is it a global issue or a website issue ?
How can I ensure that I can track the correct number of people who entered my store ?
Kind regards,
