Description

How It Works
This workflow automates SEO content creation by aggregating multi-source research and generating optimized articles. Designed for content marketers, SEO specialists, and digital agencies, it solves the time-consuming challenge of researching trending topics and crafting search-optimized content at scale. The system pulls discussions from Reddit, videos from YouTube, and industry news via APIs, then combines this data into comprehensive insights. An AI agent analyzes aggregated research, performs Google Search SEO analysis, consults Wikipedia for accuracy, and generates structured, SEO-optimized HTML content. The final output saves automatically to Google Sheets for easy management and publishing workflows.
