It requires cultivation! –
Facebook and Twitter were key for us this year, but the banner in the front did most of the work. I also sent the wife to a Harvest Festival in the neighboring town on one of the nights to pass out flyers. That had great results as well. I might do a few radio spots only because we are in a really rural town and radio is all they have out here (and its cheap - $10 for 60s spot). I posted something fresh on FB and Twitter every day (sometimes twice a day) to draw new followers. There are great apps out there to assist with that. A friend of mine that does consulting showed me one I am adding this year called TweetAdder that actually helps you find others tweeting about Halloween, and helps you narrow your focus to specific areas.
Be religious about your posting and make it interesting. Not just stuff about your hours, etc. Tell stories, carry news about the holidays, post facts about Zombies, Viruses, etc. Soon you will build a following. And it will continue to grow year after year. Yeah, I did say year after year. It has to be cultivated so if you thought you were going to make a big profit year one, sorry. Even though we had a 600% increase in revenues this year, I am still far from a profit, and still in my growing stages (growing meaning both in attendance as well as building the haunt to be bigger and better every year).
Isn't running a business fun!
