This n8n workflow automates the process of creating high-quality Facebook ad headlines for products using AI. It captures product information via a form, generates headline ideas with OpenAI’s GPT-4 model, evaluates the quality using customizable criteria, and iteratively improves the headlines until they meet a defined standard. The workflow begins with a user submitting a product brief through a form, which then prompts the AI to come up with a compelling headline. The headline is assessed against objective scoring metrics, and if it doesn’t meet the quality threshold, the process repeats. Otherwise, the final headline is sent via email. This setup streamlines ad copy creation, saves time, and ensures data-driven quality control, making it ideal for digital marketing teams looking to scale and automate their ad content generation.
