Cómo implementar el seguimiento de la ubicación del dispositivo Android en su sitio web

Estoy involucrado en el transporte de carga en mi gacela y tuve la idea de crear una función para rastrear mi ubicación para todos los visitantes de mi sitio. Esto es muy conveniente para quienes están vigilando su carga o quienes esperan un automóvil. Me las arreglé. Y en este post os contaré cómo implementar esta función, que, por cierto, es bastante económica. El artículo está dirigido a personas que casi no tienen experiencia en el campo de la creación y programación de sitios web en general.
