Having your original characters freind people or be in the maybe you know this person catagory all year long costs nothing. People who dig it will join, people that don't like anonymous characters are no fun anyhow. It onviously is an advertisement for the haunt web site but not blatantly forced on anyone, you can invite everyone to an event!
Every post like casting calls, build out crew, set designer, make up people, are all excuses to contact everyone on the planet you have been able to freind organically.
Pay per click at 50 cents a pop still means only one in 20 might actually get off the couch and come buy a ticket so you have really paid $10 per customer. Hopefully they bring another person or two is your only hope. $10 a customer might be wonderful if you were a dentist and each visit made $140 minimum per ticket. on the other hand, that $50 budget might be fine as an investment long term but, I think it is expensive. I would not expect year to year loyalty or excitement but for small percentages of people.
I had some soliciter call my phone and tell me that is why Google is so rich and it would work for me too! They want to pay Google 50 cents and they want 50 cents too! So I give them $1 pay per click and somehow I'm thinking yeah, that is why google is rich because someone gave them money. It doesn't mean the crap coverted to anyone coming to your business and making a profit.
It just depends on whether you are sitting on stacks of cash or not. I have heard tale of big city people doing such things but they only see 10,000 customers in an immediate area of 240,000 population. If it really worked they would be at 24,000 people so I'm not impressed.
Another fabulous post from the U.S.Department of Wild Imaginings, now in spectaclar stereo, sponsored by the Adhesives and Sealants Council, suggesting ways to stick things together since the 1800s. Not fabulous in a gay way. Your results may vary. Illinois residents add 8% sales tax.
