this domain is parked; the rank measures the placeholder, not the company — the homepage says “domain name is for sale”

this domain now redirects elsewhere; the rank measures whoever it points at — the homepage redirects to outible.com, a different site

a — means that source hasn't ranked the site; the average uses whichever exact ranks exist

matches the domain; subdomains get the same numbers, so skip the www
