Often the publisher will state his or her name, company name, etc. on a page designated to that information or at the bottom of the page. If you can not find it there or they do not provide it, you have a few options.
First, you could simply look at the source file. In your viewer (webpage browser) go to “view source”. There you will see the HTML of the page – in other words the programming that makes it show up. Sometimes in the meta tags or elsewhere around the top of the page you will find the author of the page. This is usually placed there without knowledge if someone is using a generic webpage development program like Dreamweaver or Rapid Weaver, etc. These programs have registered users and the registered user shows up in the page.
A second way is to go a “Whois” site. Something like “Whois.com”. If you know a site is hosted through someone like Godaddy or some other company, you can go directly to their home sites, and search the whois database there. You will get a long list of information about the page and it should define who owns it. The exception is that sometimes the person purchases a privacy certificate to keep their name off the page. This could be done for corporate pages made by one person, but representing a corporation, a church page, a sexually related site – gotta keep that info from your pastor (lol) – or some other reason. If they have done this, then the site is protected. The only way you can likely track down the name then is to file a disclosure lawsuit, but you’re going to have a very good, legal reason for wanting the name of the person.
Finally, if the above fails, look for a contact on the site, contact the site administrator and just ask “Hey, who you be?” so to speak. You might find that people answer sometimes. You can never tell for sure if they are being honest, but it’s worth a try.
