Quick answer is YES. Humor makes you human and memorable. We all recognize the Geiko commercials on the radio and on television. They work! My advice is to be careful, a company like Geiko has an almost unlimited budget. Their marketing is not the same type of investment as a smaller company. Most companies need to get the "most bang for your buck." Humor works but you also need to get your message across to consumers. My recommendation is to be yourself....don't force it. Have a well thought out plan. You can use social media for humorous posts (keep it professional though). Spend your marketing budget on ads that will fill your lobby or store or will make your phone ring.
