You have no control over WOM - what is said, who says it, when they say it, to whom they say it, or if it's said at all.
It'd be great if everyone at an event/wedding went home and told everyone they know about you. Doens't happen.
IF you rock it then maybe someone will notive and be impressed and remember that you're good. BUT ... do they know how to refer you (name, number, etc?)
It's unlikely they'll randomly tell people about you. I bet you don't do much of that, so they won't either.
So you're only hope is when someone within earshot of them mentions something that needs a DJ they'll but in and speak up with your name. Now it does happen.
In DJNews there is an article on referrals that is over the top...'you should get the prospect and referring person and yourself all together and chat"..in what world does he live that folks have this kind of time?
At work they talk about say, wings, so I mention my fave place for wings..but i'm not gonna take them there and intro them to the owner, and the same for where i get my car fixed or bought my last guitar.
To me a referral is when you get a call "I"m getting married and debbie told me to call you" Anything isn't a referral IMO.
WOM would be "I'm getting married and I've heard good things about you" and you ask where/from who.
If they say "the reviews online of you are great" - is that WOM?
You guys DO realize that some forms of advertising work for some people...and not for others!
There are SO many variables!
The ONLY system of advertising that works for ALL of us is WORD OF MOUTH.
Fortunately, it's also FREE advertising.
