Example use cases
SEO heading length audit
“Analyze the H3 headings on https://myblog.com/article and tell me the text length statistics — I want to know if any headings are too long or too short for SEO best practices.”
Content consistency check from raw HTML
“Here's some HTML I have — can you compute the text length statistics for all the H3 elements in it so I can see if the headings are consistent in length? The HTML starts with <!doctype html><html><body><h3>Intro to products</h3><h3>Advanced guide</h3></body></html>”
Competitive heading analysis
“Go to https://competitor.com/features and extract the text length statistics for all H3 headings on that page — I want min, max, and average lengths so I can benchmark against our own content.”
