Finding Your Real Market: TAM, SAM, and the Filters You're Probably Skipping

(Part 1 of a 2-part look at defining and sizing your target market.)

Ask most business owners who their target market is and you'll get an answer somewhere between "everyone who needs what we do" and a shrug. Here's the deal: "everyone" isn't a target market. It's the absence of one. And a business without a real, defined target market isn't executing a strategy, it's throwing darts in a dark room and calling whatever it hits a customer.

Target Market Analysis fixes that. It's a behavioral study of your customers and your competition. And it's not a one-and-done exercise; this needs to be revisited annually, if not more often, because markets shift and change and so do the people in them.

What You Need Before You Start

Before you touch any market data, you need three things in hand. First, you need to know the specific industry you operate in, along with its size, growth rate, and current trends. And yes, plenty of businesses legitimately operate across multiple industries because of the range of products they offer.

Second, you need total clarity on what you're actually selling. You can't identify a target market for a product you haven't fully defined. What's the perceived value or utility to the end user? Each distinct product or service line needs its own analysis. You don't get to lump them together and call it done.

Third, you need access to market research data, or you need to know where to find it. Good news: it's out there, and it ranges from free to genuinely expensive depending on how specific and accurate you need it to be. Start with public census data and free sources. Only spend real money on granular data once you've narrowed things down enough that the granularity is worth paying for.

From the Whole World Down to Your Actual Market

Here's where most owners get the sizing wrong. There isn't one "market" – there are three concentric circles, and you have to work through all of them in order.

Total Available Market (TAM) is the theoretical ceiling. It’s the entire realistic market for your product or service within your industry, filtered down by the obvious realities: geography, political boundaries, language. In today's economy, your TAM could technically be the whole world. That doesn't mean it's useful to think about it that way.

Serviceable Available Market (SAM) is where things get honest. This is the market you could realistically serve given your organization's true core competencies, resources, and production or service capability. How far are you actually capable or willing to travel to service a client? If you're selling digital downloads, which platforms will you support? You have to know your own limitations and apply them without flattering yourself.

Target Market is the final narrowing. Where you can make the biggest splash with the resources you've got, based on how your offering genuinely fits the wants, needs, and desires of a specific group of people. What age range uses more of what you sell? What lifestyle makes someone likely to want this?

Skip any one of these three filters and you end up either dramatically overestimating your reach (TAM without SAM) or targeting a market you can't in reality serve well (SAM without a real Target Market layer on top).

Segmenting Down to Something Useful

Once you've got your SAM, you segment it down to your actual target market using four lenses:

• Geographic – nations, states, regions, cities, even postal codes
• Demographic – age, gender, marital status, family size, income, education, occupation
• Psychographic – lifestyle, interests, values, opinions, attitudes
• Behavioral – tracked knowledge of, attitude toward, and usage rate of what you offer

How granular you can get depends entirely on how granular your data is. And here's the trade-off worth knowing up front: the data that's hardest to come by and most expensive is also almost always the most valuable. What are your customers' actual unfulfilled needs? How often do they buy something like what you sell? What are they really willing to spend?

The Coach’s Play Call

Don't skip straight to, "Our target market is small businesses," or, "Our target market is homeowners." That's not a target market, that's a category. Work the filters in order: know your industry, know your offering cold, get your hands on real data, then narrow from TAM to SAM to an actual defined Target Market before you segment it further. The businesses that skip this groundwork aren't executing a strategy, they're guessing with confidence.

Next up in this 2-part series: Once you know who your target market is, you still have to figure out how much of it you can actually win… and who's standing in your way.
