Create SEO Outlines from Top Google Results with SerpAPI and GPT-4o

Overview Use this workflow to create SEO-friendly outlines based on articles that do well in Google.

Enter a keyword, and the workflow scrapes the top results, scrapes the content, analyzes it with AI, and builds a MECE (mutually exclusive, collectively exhaustive) outline.

It’s useful for content creators and SEO specialists who want relevant, well-structured content.

How it works Accepts a keyword submitted through a form Uses the SerpAPI to get top Google results for a chosen country Collects the top five URLs. We use five because we expect some to fail at the scraping stage Scrapes each URL separately Uses the first three articles to fit the AI model’s context window Extracts the main text from the page body Converts HTML to Markdown to get rid of tags and attributes. Combines the cleaned text into a single list for AI processing Analyzes the content with an AI language model to find common topics and headings Generates an SEO-focused outline based on the most frequent topics
