      FIGURE 2-1: Social media would fit near the top of the ROI scale for Internet-marketing tactics.

Social media marketing runs the gamut of rapport-building options because it involves some or all of these techniques. On this scale, most social media services would probably fall between customer referral and SEO or between SEO and PR/link building, depending on the type and aggressiveness of your effort in a particular marketing channel. Traditional offline media, by contrast, would have a lower ROI than banner advertising.

      If you garner leads online but close your sales and collect payments offline, you can frame CAC as the cost of lead acquisition, recognizing that you may need to add costs for staff, collateral, demos, travel, and other items to convert a lead.

      To put things in perspective, remember that the traditional business school model for offline marketing teaches that the CAC is roughly equivalent to the profit on the amount a customer spends during the first year.

      Because you generally see most of your profits from future sales to that customer, you must also understand the lifetime customer value (how much and how often a customer will buy), not just the revenue from an initial sale. The better the customers, the more it’s worth spending to acquire them. Harvard Business School offers an online calculator for determining lifetime customer value at http://hbswk.hbs.edu/archive/1436.html.

      Small businesses (fewer than 100 employees), new companies, and new products usually need to spend toward the high end of the scale on marketing initially — perhaps even more than 11 percent. By comparison, mature, well-branded product lines and companies with a large revenue stream can spend a lower percentage on marketing.

      Obviously, anything that can reduce marketing costs offers a benefit. See whether your calculation bears out that cost level for your investment in social media.

      One is silver and the other gold

      You might remember the words to that old Girl Scout song: “Make new friends but keep the old; one is silver and the other gold.” To retain customers, apply that philosophy to your policy of customer satisfaction. That may mean anything from sending holiday greetings to establishing a loyalty program with discounts for repeat buyers, from entering repeat customers into a special sweepstakes to offering a coupon on their next purchase when they sign up for a newsletter.

      A marketing truism states that it costs anywhere from 3 to 30 times more to acquire a new customer than to retain an existing one. (For details, see www.linkedin.com/pulse/what-cost-customer-acquisition-vs-retention-ian-kingwill.) Although costs vary with each type of business, it’s common sense to listen to customers’ concerns, complaints, product ideas, and desires.

      Thus, while you lavish time and attention on social marketing to fill the top of your funnel with new prospects, don’t forget its value for improving relationships with current customers and nurturing their involvement with your brand.

Establishing Key Performance Indicators for Sales

If you track ROI, at some point you must track revenue and profits as business metrics. Otherwise, there’s no ROI to compute. Unlike the previous emphasis on social media for customer engagement, recent statistics show a rapid increase in social commerce (direct sales from social media), as shown in Figure 2-2. According to data from Statista, social commerce sales in the United States is expected to quadruple in the next five years, from $22 billion in 2019 to $84 billion in 2024.

      If you sell online, your storefront should provide ways for you to slice and dice sales to obtain crucial data. However, if your sales come from services, from a brick-and-mortar store, or from large contractual purchases, you probably need to obtain revenue statistics from financial or other external records to plug into your ROI calculation.
