As a small business owner you are constantly bombarded with marketing and advertising opportunities. You can buy ad space in various magazine, send out mailers or coupons, buy Facebook ads or Google adwords, or list your company on any of the various directories. Getting your name out there is great, but small businesses usually come with small advertising budgets.
Sure, a phonebook listing was great 20 years ago. Now, everyone is finding you or not finding you on the internet. Whether it's someone surfing the net at work for a new lunch place or a mom in the car trying to figure out the closest place to cart her kids for a last minute haircut, everyone is constantly connected to the net and if you're not on it, you don't exist. Even customers that walk or drive by your business are likely to search on their mobile phone for your reviews or menu.
