Example use cases

HTML snippet link relationship check
“Here's some HTML I have — can you extract all the rel attributes from the anchor tags in it? I need to know which link relationships are declared.”
Competitor link strategy analysis
“Can you fetch https://competitor.com and tell me all the rel tokens used in their anchor tags? I'm trying to understand their internal linking strategy.”
