5 Key Ways to Build Customer Relationships Never underestimate the value and reach of a loyal, repeat customer. Keep customers coming back for more--and bringing their friends with them--with these smart tips.

Money can't buy one of the most important things you need to promote your business: relationships. How do customer relationships drive your business? It's all about finding people who believe in your products or services. And when it comes to tracking these people down, you have two choices:

You can do all the legwork yourself and spend big marketing dollars. But that's like rolling a boulder up a hill. You want to drive your business into new territory, but every step is hard and expensive. There's another less painful--and potentially more profitable-way...

You can create an army to help you push that boulder up the hill instead. How do you do that? You develop relationships with people who don't just understand your particular expertise, product or service, but who are excited and buzzing about what you do. You stay connected with them and give them value, and they'll touch other people who can benefit your business.

Powerful relationships don't just happen from one-time meetings at networking events--you don't need another pocketful of random business cards to clutter your desk. What you need is a plan to make those connections grow and work for you. And it's not as hard as you think. Here are five essential tactics:

1. Build your network--it's your sales lifeline. Your network includes business colleagues, professional acquaintances, prospective and existing customers, partners, suppliers, contractors and association members, as well as family, friends and people you meet at school, church and in your community.

Contacts are potential customers waiting for you to connect with their needs. How do you turn networks of contacts into customers? Not by hoping they'll remember meeting you six months ago at that networking event. Networking is a long-term investment. Do it right by adding value to the relationship, and that contact you just made can really pay off. Communicate like your business's life depends on it. (Hint: And it does! Read on.)

2. Communication is a contact sport, so do it early and often. Relationships have a short shelf life. No matter how charming, enthusiastic or persuasive you are, no one will likely remember you from a business card or a one-time meeting. One of the biggest mistakes people make is that they come home from networking events and fail to follow up. Make the connection immediately. Send a "nice to meet you" e-mail or let these new contacts know you've added them to your newsletter list and then send them the latest copy. Immediately reinforce who you are, what you do and the connection you've made.

You rarely meet people at the exact moment when they need what you offer. When they're ready, will they think of you? Only if you stay on their minds. It's easier to keep a connection warm than to warm it up again once the trail goes cold. So take the time to turn your network of connections into educated customers.

3. E-mail marketing keeps relationships strong on a shoestring budget. Build your reputation as an expert by giving away some free insight. You have interesting things to say! An easy way to communicate is with a brief e-mail newsletter that shows prospects why they should buy from you. For just pennies per customer, you can distribute an e-mail newsletter that includes tips, advice and short items that entice consumers and leave them wanting more. E-mail marketing is a cost-effective and easy way to stay on customers' minds, build their confidence in your expertise, and retain them. And it's viral: Contacts and customers who find what you do interesting or valuable will forward your e-mail message or newsletter to other people, just like word of mouth marketing.

4. Reward loyal customers, and they'll reward you. According to global management consulting firm Bain and Co., a 5 percent increase in retention yields profit increases of 25 to 100 percent. And on average, repeat customers spend 67 percent more than new customers. So your most profitable customers are repeat customers. Are you doing enough to encourage them to work with you again? Stay in touch, and give them something of value in exchange for their time, attention and business. It doesn't need to be too much; a coupon, notice of a special event, helpful insights and advice, or news they can use are all effective. Just remember: If you don't keep in touch with your customers, your competitors will.

5. Loyal customers are your best salespeople. So spend the time to build your network and do the follow-up. Today there are cost effective tools, like e-mail marketing, that make this easy. You can e-mail a simple newsletter, an offer or an update message of interest to your network (make sure it's of interest to them, not just to you). Then they'll remember you and what you do and deliver value back to you with referrals. They'll hear about opportunities you'll never hear about. The only way they can say, "Wow, I met somebody who's really good at XYZ. You should give her a call," is if they remember you. Then your customers become your sales force.

If real estate is all about location, location, location, then small business is all about relationships, relationships, relationships. Find them, nurture them, and watch your sales soar.
