Why Market Size Matters: How to Find the Perfect Audience for Your New Business

December 22, 2025


When it comes to starting a business—especially one based on your personal skillset, such as web design, consulting, coaching, or any kind of professional services—one of the most crucial things you can do before launching is to understand your market size. Far too often, individuals leap into business ownership because they are highly skilled, wonderfully passionate, and deeply tired of pushing someone else’s goals without giving due attention to the fundamental matter of how big, accessible, and receptive their target market really is.

Let’s break down why market size is such an important factor at the beginning of your entrepreneurial journey, what common pitfalls occur when this gets overlooked, and step-by-step, how you can evaluate your own market to increase your chances for long-term success.

Why People Start Without Reviewing Market Size

For many, starting a business is an emotional decision. Maybe after years of developing a talent and perfecting their craft, they’re tired of working for somebody else and want to build something they own. Maybe they seek the flexibility, the pride, and the security that comes with entrepreneurship. Perhaps you, too, are in that situation, ready to take your skills and branch out as your own boss.

What often gets missed in this leap is understanding the business mechanics outside of your technical skills—most notably, whether demand exists for your services in a way that can sustain not just an income, but the ongoing costs and growth you’ll face. Many are used to jobs where the flow of work is constant and someone else handles the sales, marketing, and operations. When you strike out solo, you quickly realize that attracting and retaining clients, managing dry spells, and maintaining cash flow becomes much more challenging.

Starting With One Client: The Danger Zone

It’s common to begin with one large client—maybe a prior employer or a big connection in your network. The security feels great at first, but it can lead you into a false sense of stability. Many new consultants, designers, or freelancers find themselves in deep trouble when that client leaves, scales back, or hits financial troubles. If you haven’t established a pipeline for new clients, you could watch your business unravel, not from lack of skill or effort, but simply because the market around you wasn’t sized or developed adequately.

Understanding Market Size: Local and Online

So how do you prevent these pitfalls? It starts by sizing up your market effectively—locally or online, depending on your offering.

1. Assessing Your Local Market

When you are serving a specific geographical area—be it a city, county, or a defined region—knowing your potential customer base is key. First, take a look at the population size: how big is your city or area? Is there enough of a customer base to sustain your business, especially when considering that not everyone will need your service now, or ever?

Beyond sheer numbers, consider how you will reach your potential customers. Is your marketing message visible enough? Are you joining the right groups and associations to generate referrals? If you’re relying on word-of-mouth, understand how far those networks actually reach.

Use tools like Google search or business directories to research how many businesses or independent professionals provide services similar to yours in your city or region. Here’s an insight: if you have fewer than four direct competitors, the market may be too small; demand might not be enough to keep the lights on. On the other hand, if you see more than ten active competitors, you may be entering a saturated market—where getting noticed, gaining clients, and carving out space for yourself is much tougher.

A competitive landscape of four to ten businesses is often the “sweet spot.” This means there is visible demand—enough to ensure regular flow of clients—but not so many that your marketing voice is drowned out.

2. Evaluating Online/National Markets

If your service or product is offered online and you’re targeting a regional or national audience, the numbers changes drastically. There, it’s less about the physical proximity and more about total interest at scale.

Here, you want to focus on markets with an active audience size of 1.5 million to 2.1 million people interested in your niche. This is not about the general population—these are specific to your target interest area. If you have a niche as a web design coach, for instance, you need to focus on how many people are actively seeking coaching, training, or services related to web design and technology.

Why these numbers?

- Less than 1.5 million: There simply aren’t enough people to ensure that your content, ads, or posts are seen enough times for you to build relationships, get shares, and achieve the kind of engagement that converts to sales.

- More than 2.1 million: The space becomes noisy and fiercely competitive. Established brands, aggressive marketers, and bigger budgets make it difficult for your posts, products, or messages to be noticed, especially when you are just starting out.

How Do You Determine These Numbers?

- Use Keyword Tools: Google’s Keyword Planner, Ubersuggest, or SEMrush can give you search volume estimates for your niche, both locally and nationally.

- Survey Your Competitors: Count how many businesses or influencers are actively targeting your area of expertise. Check out business listings, Google Maps, or industry associations.

- Social Media Research: Look at Facebook Groups, LinkedIn connections, Reddit communities, and Twitter hashtags for followers, group members, or interaction volume around your service.

Practical Example

Let’s say you’re in Santa Barbara, California—home to a unique blend of small, tech-savvy businesses and creative entrepreneurs. You want to teach automation tools for web design, PC, and Mac users.

Start locally. Look at how many business owners, freelancers, or hobbyists might need your level of training. Check Meetup groups, LinkedIn, and local business associations—you’ll find your competitors and your target market already gathering.

Then, look at search traffic, both for your city and nationally. How many people are searching for things like “web automation training,” “AI tools for small business,” “automation for Mac users,” and related topics? Make sure you land in that 1.5M-2.1M sweet spot.

Marketing Reach Matters

Once you know there’s enough market, think about how far your marketing efforts can realistically extend. Locally, how many people can you physically meet, network with, and engage through targeted ads or events? Nationally or globally, is your content optimized for the keywords your audience is searching for? Are you posting at times your audience is online? Is your brand or idea niche enough to gain early traction, but broad enough for healthy growth?

The breadth and quality of your marketing reach will be decisive: if you can’t get seen by enough of the right people, even a perfectly sized market won’t help you.

Referral Networks: The Local Advantage

Never underestimate the power of personal recommendations. Referrals can be one of your greatest assets, especially if your market isn’t so broad. Joining local business groups, chambers of commerce, and service organizations can greatly extend your reach. Pay attention to how interconnected your market is: in tight-knit areas, word can travel fast—both good and bad—so make sure your initial reputation is strong.

Online Authority: Cutting Through the Noise

If you’re working online, build your authority clearly and quickly:

- Develop high-value content (tips, guides, case studies).

- Leverage social media platforms with concentration—not trying to be everywhere, but dominating where your target demographic hangs out.

- Seek guest spots on podcasts and blogs already serving your market.

- Participate actively in niche forums.

Remember, with a competitive market, you’ll need a unique angle, a fresh voice, or specialized experience to get noticed.

Ongoing Market Monitoring

Your job isn’t done when you launch. The market changes constantly—new competitors enter, consumer interests shift, online platforms evolve. Make it a habit to regularly monitor your market size and demand. Set a recurring reminder to check keyword searches, Google Trends, and to audit your local competitors every quarter.

Be ready to pivot as needed. There may be opportunities to specialize further, to add complementary services, or to scale nationally or even globally as your brand and expertise grows.

Final Thoughts

The excitement of working for yourself, turning your passion into your paycheck, and building your own legacy is unmatched. But too many promising ventures sink because the market—the oxygen of your business—was an afterthought.

By objectively sizing up the demand and competition before you start, and by consistently monitoring it as you grow, you can position yourself not just as another skilled professional, but as a sought-after resource for a healthy, sustainable, and profitable client base.

Being methodical doesn’t quash your entrepreneurial passion—it fuels it, by ensuring that your talent and energy are applied where they’re most likely to flourish. Take the time, do the research, and launch your venture with eyes wide open to your true market potential.

If you’re ready to take the next step in your business journey, start today by researching your market size. It’s an investment in not just your business, but your future.
