Le jeu de l'influenceur : Maximiser ta portĂ©e pour la monĂ©tiser. Tu poursuis le reach.\n- Avantage : une portĂ©e de fou qui fait plaisir Ă l'Ă©go\n- InconvĂ©nient : corrĂ©lation faible entre performances du contenu et retombĂ©es business.\n2. Le leadership d'opinion : DĂ©velopper ta marque personnelle pour occuper une thĂ©matique et en ĂȘtre au sommet. Tu mesures ton leadership Ă la frĂ©quence Ă laquelle on t'invite en confĂ©rence ou en podcast pour partager Ă ce sujet.\n3. Le jeu entrepreneurial : Produire du contenu pour gĂ©nĂ©rer des ventes en s'adressant Ă son client idĂ©al, en partageant son expertise et ses rĂ©sultats.\n\nMon conseil : choisis le jeu entrepreneurial.\n\nĂtape 2 : dĂ©finir ton client idĂ©al\nLe client idĂ©al se trouve Ă l'entrecroisement de 4 facteurs :\n\n1. ProblĂšme-solution fit trĂšs fort : Tu lui vends A, tu lui dĂ©livres A, il est content de recevoir A et rachĂšte potentiellement A\n\n 2. FacilitĂ© de gĂ©nĂ©ration de rĂ©sultats : Tu le connais, il est bien positionnĂ©\n\n3. Il te paie bien, rapidement, beaucoup et sur la durĂ©e : Bonne lifetime value\n\n4. Fit humain : Tu pourrais aller dĂ©jeuner avec lui\nL'anti-client, c'est l'inverse :\n- Il convertit lentement\n- Rechigne Ă payer\n- Tu galĂšres Ă produire pour lui\n- Le fit humain est faible.\n\n \n\nIdentifier ces deux profils dĂ©termine Ă©normĂ©ment de choses et Ă©volue dans le temps.\nL'anti-client, c'est l'inverse :\n- Il convertit lentement\n- Rechigne Ă payer\n- Tu galĂšres Ă produire pour lui\n- Le fit humain est faible.\n\n \n\nIdentifier ces deux profils dĂ©termine Ă©normĂ©ment de choses et Ă©volue dans le temps.\n\nĂtape 3 : ne plus parler qu'Ă ton client idĂ©al\nVoici la ligne Ă©ditoriale thĂ©orisĂ©e d'un entrepreneur. Il n'y a que trois sujets dont parler :\n\n \n\nLe problĂšme : Tu explores la problĂ©matique sous toutes ses dimensions :\n- Le coĂ»t d'opportunitĂ© de ne pas le rĂ©soudre\n- L'urgence\n- Les consĂ©quences.\n\n \n\nLe problĂšme doit ĂȘtre douloureux, urgent, reconnu.\n\n \n\nLes solutions concrĂštes : Tu transmets ton expertise et dĂ©montres pourquoi ton option est la meilleure pour ce client idĂ©al spĂ©cifiquement.\n\n \n\nLes preuves : Cas clients, tĂ©moignages qui illustrent tout ça. C'est ce qu'on fait jamais assez car ces posts gĂ©nĂšrent moins de portĂ©e, mais nettement plus de conversions.\n\n \n\n95% du contenu doit corrĂ©ler Ă ces 3 piliers : problĂšme,solution,preuve.\n\nĂtape 4 : on s'adresse Ă des TPE\n\nTu n'hĂ©sites pas Ă citer des rĂ©fĂ©rences et des parties de texte intĂ©ressantes ! Ton texte sera viable sans que j'intervienne pour mettre des liens ou autres, tu n'ajoutes pas dans ton texte Joker : Je suis une IA dĂ©guisĂ©e !\n\n \n\n"
