Promoting your business doesn't have to mean shelling out thousands of dollars. In fact, some of the most effective methods of expanding your client base and spreading the word about your company cost next to nothing. Here are a few impactful ways to advocate for your business:

1. Print business cards
Ordering business cards in bulk can be inexpensive, and when you're handing them out to potential clients and other individuals in the industry, word about your business can spread fast.

2. Send holiday cards
Business holiday cards are a simple way to send your clients festive greetings and show them how much you appreciate their business. You can also send cards to clients you haven't spoken with in a while to remind them of your services. Handwritten notes are an easy and inexpensive ways to make customers feel special.

3. Set up a LinkedIn business profile
LinkedIn is a fast and efficient way of not only promoting your business, but connecting with others in your industry. Your LinkedIn profile is the perfect opportunity to include links back to your website, share industry news, post open job positions, participate in conversations about your business and talk about your products and services. Feel free to set up professional profiles on other free social media platforms such as Facebook, Twitter and Google+ as well.

4. Donate some of your products
Consider donating some of your products to a charitable event. Not only will this shine a positive light on your business, it's also a great opportunity to get your products and services out there. For instance, a coffee distributor may want to donate coffee and espresso machines for a charity event. People will take notice of the product and may even be prompted to do further business with the company.

5. Speak at an event
Volunteer your time to speak at an industry conference, local business, charity, etc. Speaking on a topic can help you and your company gain credibility and recognition in your field.
