A hypothetical brand finds 40 domains that resemble its name. Most are parked. One appears in a sponsored search for '[brand] login' and sends mobile visitors to a copied sign-in page.
That one gets priority.
I would rank the list by visible customer harm: search or ad exposure, live redirects, copied login or checkout, repeated visibility by country or device, then parked names.
For each live case, save the query, country, device, time, ad copy, redirect chain, final URL and screenshots. That gives a registrar or host something reproducible instead of a list of suspicious names.
How do you decide which lookalike domain to investigate first?
