Final answer:
Yes, offering business cards to customers and asking them to share with friends can be an effective networking strategy when done correctly. It helps to build a professional image and can be more influential than traditional advertising, however, it should be targeted at satisfied customers who are likely to give a positive recommendation.
Step-by-step explanation:
Offering several of your business cards to customers with the request that they hand them out to friends can be a good strategy, assuming it's done respectfully and to the right audience. This method leverages what is known as word-of-mouth marketing, an effective form of networking. It allows for a personal recommendation to take place, which can be more influential than traditional advertising.
Ensuring that you have a well-designed, professional networking business card will also contribute to a positive impression and build your professional image. However, it is important to be mindful of how you approach customers with this request, as not everyone may feel comfortable with this type of referral system. Hence, it's crucial to target customers who show strong satisfaction with your services or have a good relationship with your business.
