Looking at old Flippa auctions<\/a> that I scraped<\/a>, it would be interesting to determine if domains are parked. I found this post<\/a>, which describes a few options, including checking DNS entries for redirects, finding a blacklist, or content inspection. Some people have built APIs, but none appear maintained, and DNS providers rate limit whois lookups. Google also has an internal, proprietary method for doing this.<\/p>\n

I’ve compiled a list of text included in parked pages. I found that GoDaddy<\/a> is a very common domain parker, and encompasses most of the results in my dataset, but the others are useful too. Many hosting companies operate through common providers, so the text often follows a pattern. A portion of parked sites sell their traffic to third parties, often “mom” sites – these can’t be detected through this method. If you find a parked domain that doesn’t match one of these strings, please comment below!<\/p>\n
