About Global DNS Propagation Checker

A free tool that brings customers every day

This product is not a feature for your website: it is a website. DNS propagation checkers, WHOIS lookups and email verifiers are among the most searched-for pages in the technical sector, and whoever offers them receives steady visits from system administrators, agencies and people who have just moved a domain.

That is this plugin's business case: putting a set of tools on your WordPress that attract exactly the audience that buys hosting, domains or technical services.

What it checks

  • DNS propagation querying several servers at once, to see where the domain already resolves and where it does not yet.
  • Ten record types, among them A, MX, NS, CNAME and TXT.
  • Unlimited servers, added, sorted and imported or exported by file.

The tools that come with it

WHOIS, IP address lookup, and the whole email block: SPF, DKIM and DMARC verification, blacklist checker, header extractor and a sending server connection test.

That email block is the most interesting commercially. Somebody arriving to find out why their emails land in the spam folder has a problem that costs money and that they are willing to pay to solve. A far better visitor than the one only checking whether their domain has propagated.

How to actually get value from it

With two decisions that do not come with the plugin and that determine whether it is worth anything.

One page per tool. Not a menu with ten tabs: ten separate addresses, each with its own title and its own explanation of what it solves. That is the difference between ranking for one query and ranking for ten.

Something to do next. The visitor arrives, answers their question and leaves. If there is nothing in the result leading them to a next step, you have paid for hosting to help strangers for free. A link to the relevant service, an article explaining the problem found, or the option to share the result, which the plugin allows through read-only links.
