Maybe it was some great advice you heard or maybe it was a key client you landed or a new process you tried...I think it will make some entertaining reading for everyone.
Personally, my best day had absolutely nothing to do with money. I was working for a client out of Australia right after the big poker sites got seized by the FBI, and this client had me cranking out press releases for a different gaming site that accepted US players. But I was getting ultra-creative with these to make them newsworthy while pointing to our affiliate site, and we were averaging 3,000-5,000 hits per press release within an hour or two of launching them.
Well, on about the 12th day of doing this, my client calls me from Australia, which is something he had never done before. It was probably three AM his time as well so I was thinking that the FBI had to have come down hard on him or something really bad. It was quite the opposite though; he said, "Playboy wants to interview me to do a feature piece about online gambling, but I'm in Australia. So I'll pay you $xxxx to do it for me as the company spokesman."
So I called the number he gave me and they asked if I was available to travel to California for two interviews; one for Playboy and the other for Playboy Radio. And I figured that meant a trip to the Playboy Mansion, so I said yes without even thinking twice about it. That never happened though; I just went to their studios in LA for the interviews and then flew back home...so I didn't get to meet Hef or anything cool like that. They did treat me like a celebrity though and it was a very memorable trip.
Anyway, that one day got me more personal exposure than money could buy and I ended up being quoted as the premiere online poker expert in the US for months after that incident. And while I was still too new to Internet Marketing to capitalize on it, it eventually led me to a great job with an IM firm in Houston and the knowledge of how to become an authority in just about any niche. It was a very good day.
