Does anyone know how to do this? I have tried searching for the value of "google_ad_client" in the source code, but this doesn't come up with anything in Google, and I'm sure that this creator has many other sites. Is there any way to accomplish the above? Thanks
If they have a dedicated server you could use whois.sc to see the sites hosted on the same server as them. Doesn't mean the sites belong to them though.
I don't wish to plagiarize, but there is a lot I can learn from their techniques. Imitation and improvement.
