Yellow pages, a tried and true advertising medium for decades (I’m talking about the print version).
If you have a huge billboard ad in the YP print, cut that expense in half by cutting down the size of your ad. The book nowadays stays closed 99% of the time, and your ad is side by side with your competition.
Use the money you save towards another marketing media, like your website (is it optimized for search?)…video, or other 21st century method to reach your customers.
Or, contact me and we can explore how to “cash in” on your newfound asset and put some more moolah on your bottom line (sometimes a LOT more).
