PubMonitor: See sites observed on the same publisher ID, plus traffic

Hey Product Hunt — maker here. Traffic tools answer “how big is this site?” They don’t answer “what else is on the same publisher ID this month?” Reverse-lookup tools usually dump an ads.txt list. Those files can be forged, resold, or left stale. PubMonitor is a monthly index of the ad-funded web. Look up a domain or a pub-xxxx ID and you get the domains observed on that publisher — with traffic, a labeled earnings estimate, and ranked boards. Estimates are modeled and labeled.
