    Proyecto a desarrollar con PHP, Mysql , HTML, CSS y JS Se trata de una plataforma hecha a medida desde cero. Es una plataforma de gestion de modelos para una agencia de talentos. La interfaz de la plataforma está ya totalmente diseñada y ya programada por tanto el Front-end ya estaría hecho. En cuanto al Backend es lo que falta. La tecnología a usar es preferiblemente PHP sin framework aunque se aceptan otro tipo de propuestas (Laravel.. ) Es muy preferible que sea de habla hispana, mas que nada por que para entender ciertos flujos del software lo va a entender mucho mejor al ser en español.

    Hola me dedico a la monetizacion con google, por tanto mi trafico lo gestiono de redes sociales como facebook, pero el trafico social es muy malo para la monetizacion, por tanto me surgio la idea de algun metodo o forma de hacer que el trafico que envio de mis campañas de facebook, no lleguen como que son de facebook ni mucho menos como trafico Referencial, lo unico que me funciona es el trafico directo, por tal razon la idea aqui es que el trafico al llegar a mi pagina sea trafico directo, por ejemplo si tomas un enlace de una pagina y lo compartes en whatsapp, cuando alguien haga un click en ese enlace, ese trafico sale en google analitycs como trafico directo, y es esa funcion exactamente la que busco, que el trafico llegue directo.
