What is best bulk domains checker software (preferably free) to check PR, DA, indexing , domain availability, domain expiry etc? By bulk, I mean 50, 000 to 100,000 domains not just a few hundred domains. Presumably will need to download a desktop software instead of checking online at a website Thanks
Try PaRameter. You can use it only for checking pagerank, but is still pretty useful. Here's the link: http://www.cleverstat.com/en/page-rank-software.htm
+A Bulk Domain Checker can check thousands of domains for expiration date, availability and status. It currently has support for handling 111 top-level-domains. You can import or extract domains from files, generate domains based on keywords, search the web for domains or generate misspelled domain names.
I know this thread is a little old..But if you're still using I would recommend checking out NameChex. You can easily check 50K-100K per day!
By the way, there one program for bulk domain checking - whic.ru (WHoIs Client). The free version checks Russian zone (ru, su, RF, etc.). Pro version paid costs from 12$ to 40$, if you convert rubles into dollars.
I use two tools to check. 1. Bulk Domain Authority Checker (free) 2. NameChex Bulk Domain Software ($49.99)
Bulk domain checker software allows to check hundreds and thousands of domain. You can get many tools on internet to do so.
I don't like to use online services to search for available domains, at least in the case of bulk whois. I use either a whois servers of official registrars. It is safe and secure. Either use the software if search and analysis should be bulk, in particular, Whic or others. I can control the traffic any software using a simple firewall. And here is how to control online services..? There is only blind trust
