To ensure success, every Delaware Valley business owner needs to advertise.

"Think you have a great product?" asks the US Small Business Administration. "Unfortunately, no one’s going to know about it unless you advertise.”

The SBA goes on to say, “Advertising, if done correctly, can do wonders for your product sales, and you know what that means: more revenue and more success for your business.”

There are dozens of ways for local small business owners to advertise. By most metrics, the best way to advertise is on Philadelphia radio. These measures of effectiveness, however, are often obscured by the glimmer and glitz of newer technologies. 

To help reduce the glare that often blinds business owners to the potency of advertising on Philadelphia radio, here are the top five things many local business owners get wrong.

"I wish I had known about radio advertising when we opened up our first store in 1998," says the Dan DiZio the co-founder and CEO of Philly Pretzel Factory. "It would have allowed us to grow even faster than we did."

With permission of his Mom, an 11-year old Mr. DiZio began selling pretzels on the treacherous intersection of Roosevelt Boulevard and Rhawn Street in Northeast Philadelphia. His inventory was remnants from his neighbor, who owned the Kensington Soft Pretzel bakery.

"On the first day I sold 1000 pretzels", recalls Mr. Dizio. "After splitting the profits with my neighbor, I had $100 left in my pocket. A lot of money for an 11-year-old."

Shortly after that, Mr. DiZio began recruiting 40-50 classmates a day to hawk even more pretzels on street corners all over the neighborhood.  This early taste of franchising kept his pockets very full through middle school, high school, and into college.

This was the origin of what, today, is a $50,000,000 a year business with 175 stores in 17 states. Eighty-five of those locations are within 40 miles of Center City Philadelphia. Mr. DiZio has gone from selling 1000 pretzels per day to 175,000,000 per year.
