I'm not sure I understand, Hellas.
I have conducted six (6) interviews to date. I have two more coming up soon.
In every interview, I try to cover earnings information and often have the interviewee provide links to specific products or websites that are critical in producing those earnings. For example, in the first interview I ever did, with a man who made over $300,000 online, the reader gets to see his website, his promotional technique, earnings statistics, and eBook.
In the two most recent:
Aziz, the graphic design, gave the reader multiple links to his portfolio.
Zash gave us links to his proxies and his hosting company.
Both of these help 'show the success' of the person being interviewed.
So... what did I leave out?
