I remember 300 million is the number of businesses on Google maps. I forgot how I got that number though. I didn't crawl Google maps. A lot or even most of those businesses run via chat often have no physical presence besides the houses of their owners so houses on Google maps are not counted. There are a lot of businesses on shopping malls and B2B businesses that aren't on Google maps often because they don't know they can add themselves to Google maps. I did count the number of ICANN domains on their zone files on czds and there are a few services selling pre compiled domain lists that do crawling for marketers (it is forbidden by ICANN to use zone files for marketing) I don't remember how I got the active website count of 100 to 150 million, maybe I interpolated by checking some ICANN domains or there's a domain list service that does it. Domain list services usually say how many domains are active regardless of whether they have a website or not Of course parked domains add up to the active website count even though they have no relevant content
