La vidéo promettait un générateur d'idées branché sur trois sources — les tendances, les concurrents, les hashtags — et un chiffre : 1200 idées par jour.
Commençons par ce qui est vrai. La brique qui existe vraiment, celle que je te donne ici, c'est la deuxième : l'analyse des concurrents. Elle va chercher les vidéos publiées par des chaînes que tu désignes, les classe par engagement réel, garde les dix meilleures et en tire dix idées argumentées, une fois par semaine, par email. Ce n'est pas 1200 par jour. C'est dix par semaine, et chacune est adossée à une vidéo qui a réellement performé.
Le volet hashtags n'existe pas, et le volume annoncé dans la vidéo n'est pas ce que produit cet outil. Je préfère te donner la brique qui tourne plutôt qu'une page qui tient la promesse en mots et rien en fichier. Dix idées défendables valent mieux que mille lignes qu'on ne lit jamais — et c'est plutôt ça, le vrai problème d'une file d'idées.
Ce workflow est un modèle public signé Julien Sanson, que j'ai nettoyé et remis en français. Le crédit lui revient.
Ce ne sont pas des étapes idéales : c'est le contenu réel du fichier que tu vas copier plus bas.
((likes + commentaires × 2) ÷ vues) × 1000Une seule ligne de code porte l'intérêt du système, et elle mérite qu'on s'y arrête :
Elle dit deux choses. D'abord, on divise par les vues : une vidéo à 2 000 vues qui déclenche 300 réactions bat une vidéo à 200 000 vues qui n'en déclenche que 400. C'est exactement ce que tu veux copier — un sujet qui fait réagir, pas un sujet qui a été poussé par un algorithme.
Ensuite, un commentaire compte double. Laisser un like coûte un geste ; écrire un commentaire coûte une minute. Le second signal est plus difficile à obtenir, donc plus fiable pour repérer un sujet qui touche.
Le facteur 1000 ne sert qu'à obtenir des nombres lisibles plutôt que des zéros après la virgule.
UC_CHAINE_CONCURRENTE_x par de vrais identifiants de chaînes, puis [email protected] par ton adresse.Ce n'est pas le @nom visible dans l'URL. L'identifiant commence par UC et fait 24 caractères. Ouvre la chaîne, puis Partager la chaîne → Copier l'ID de la chaîne. Si tu colles un @nom à la place, les nœuds YouTube renvoient une erreur immédiate — et c'est une bonne nouvelle, tu le vois tout de suite.
Le modèle d'origine traînait une seconde copie de lui-même : un brouillon plus ancien qui n'analysait qu'une seule chaîne, laissé dans la toile et débranché du reste. Il ne servait à rien et rendait le canevas illisible à l'ouverture. Je l'ai supprimé du fichier que tu télécharges. Ce que tu importes, ce sont les vingt nœuds réellement reliés entre eux — rien de plus.
Les identifiants de chaînes et l'adresse email d'origine ont aussi été remplacés par des marqueurs. Un workflow qu'on partage ne doit pas transporter la liste de veille ni la boîte mail de celui qui l'a écrit.
