Alexa and Moz checker

Alexa and Moz

You don’t have to check your analytics or tools every day for every website that you own. You can quickly check Alexa rank, Moz rank or Moz domain authority for any domain name.

We understand that as a business owner you are interested only in the bottom line, and the numbers.

Namesever and MX check

For individual Nameserver and MX check it becomes very important on those rare occasions when you are making a migration to another hosting provider. If you think this isn’t your job, you are probably right.

But if you want to be on top of things and track changes here, so that you have a better understanding of what’s going on, this info might come in handy. Especially if you are a hosting company and want to see who is hosting that website!
