How I treat the evidence
The free lookup is enough to answer the first question: what public evidence does this site expose?
The logged-in path is for keeping history, comparing domains, and using the result as a lead record.
What is free?
The on-page lookup is free to try. Saving history, comparing domains, and repeated workflows are better after sign-in.
What makes it useful for inbound leads?
The searcher arrives with a domain in mind. They can complete the task on the page, then save the result if it matters.
