There is an "seo company" that's doing something weird. For the purpose of this question, I will name the seo company's domain seocompany.com so they create different subdomains for different businesses. like HomeDepot.seocompany.com Lowes.seocompany.com EmergencyLocksmith.seocompany.com Then on every one of these subdomains, they have the names of a bunch of cities. like san diego san francisco Los Angeles Boston Austin Houston just the names of a bunch of cities, no other content. I heard from someone that works there, the owner will then approach these businesses (Lowes, home depot, lock smith) and try to sell them the subdomain? I checked the domain and it has zero backlinks. zero. supposedly, this guy gets 200 accounts a month. What in the hell?
