I have a client that has a site that has had a number of people in charge of it. All of these people have very different opinions about what should be on the site itself.

When I look at their website on the server I see pages that do not have any obvious navigation to them.

What is the best way to find out the internal linking structure of a site and see if these pages truly are stranded?

No I wouldn't use article directories.

I think you should watch this whiteboard Friday:

When I have done google places optimization for businesses in malls I have used the general address. When I have done the verification process the clients haven't had any trouble getting their mail even if it is sent to the main mall office. I have just told them to keep an eye out for mail from Google and tell anyone who might get the mail by mistake.

Note: I live in a small town(50k) and our malls are not gigantic.

I would say it is a waste of time because of its unsustainable nature.

I totally agree, I have been asked this question a few times before and my answer is the metric for writing isn't length but are you the website owner answering the question the searcher is asking.
