This should check other basic things, for eaxmple:

* Hosted on the same IP

* Shares nameservers

* Shares an SSL certificate

* Same whois info.

That is a great idea and something we definitely hope to add in the future.

Be wary of shared SSL. For example, sites on Cloudflare often share SSL carts but are not owned by the same person. You may have to blacklist certs with Cloudflare CNs to avoid false positives.

Same with IP addresses and nameservers. Unrelated sites could share the same nameserver or IP address. But if you have a number of those factors match up then two sites are likely related.

I tried typing amazon.com, and was shown studios.amazon.com

Feels like it needs some work...

Not getting this at all! How does it help find competitive websites?

A lot of times people will use the same Google Analytics or Adsense code on multiple sites. This lets you find all the sites a particular code is used on.

Seems like bad practice. Do a lot of people do that? Why would I share the same GA code between all of my sites? It would taint my analytics data and make the analytics worthless, no?

And the places where this happens a lot (ads for example) is completely useless for this.

Google analytics tags look like this: UA-1234567-1

For each site the last digit increments. We only use the part that stays the same.

However it is fairly easy to get actually unique GA codes under the same account. But many people do not do that.

With AdSense you cannot get a different publisher ID unless you set up a whole new account.

Using Laravel Spark right?

Yup. Highly recommend.
