Ever feel like your marketing isn’t reaching the right people?
Or that you have a killer product, but not enough buyers?
Or maybe you’re getting traffic, but conversions aren’t happening?
The problem might not be your product… but your copy.
Because copywriting isn’t just about sounding good.
It directly impacts how many customers you can reach, attract, and convert.
And this is exactly why understanding your TAM, SAM, and SOM is non-negotiable.
So you should be knowing your TAM, SAM, and SOM that can mean the difference between growth and guesswork.
Wait… What the Heck Are TAM, SAM & SOM?
Think of your potential customers like a big pizza.
Not all of it is for you, but you can still get a big slice, if you know how.
🔹 TAM (Total Addressable Market) = The Whole Pizza
TAM is everyone who COULD buy your product/service without any limitations.
Example:
If you sell AI-powered CRM software, your TAM is every business in the world that could use a CRM.
🔹 SAM (Serviceable Available Market) = The Slice You Can Reach
SAM is the real market you can serve; based on your business model, audience, and capabilities.
Example:
Your SAM could be only small businesses that need AI-powered CRM and are willing to pay for it.
🔹 SOM (Serviceable Obtainable Market) = The Bite You Can Actually Eat
SOM is the portion of your SAM you can realistically convert into paying customers.
Example:
Your SOM might be 2,000 small businesses per year who will buy your CRM based on your sales efforts, ads, and market reach.
However, what’s more important is that….
Your copywriting decides how much of that market you actually get.
Let’s see how…
How Copywriting Expands (Or Shrinks) Your TAM, SAM & SOM
1️⃣ Copywriting Expands Your TAM (Or Shrinks It)
Your brand messaging decides how big your potential market is. It depends upon type of copywriting; good or bad.
How?
Good Copywriting
→ Communicates who the product is for
→ Educates people on why they need it
→ Positions your brand as an industry leader
Bad Copywriting
❌ Uses vague, generic language
❌ Confuses potential customers about what you offer
❌ Misses entire markets by being too niche or unclear
Example
- Broad TAM Copy (Too Vague): “AI-powered CRM for any business.”
- Optimized TAM Copy (Expands Market): “AI-powered CRM built for growing startups that need automation without the complexity.”
The clearer your messaging, the more people will realize they need you—expanding your TAM.
2️⃣ Copywriting Defines Your SAM (Filters the Right Audience)
Not everyone in your TAM is a perfect fit.
This is where SAM comes in; your copy should filter out the wrong people and attract the right customers.
📍 Good Copy Targets the Right Audience
↪ If your product is for small businesses, your copy should make that crystal clear so enterprise companies don’t waste time on your website.
📍 Bad Copy Attracts the Wrong Audience
↪ If your messaging is too broad, you’ll waste time dealing with leads who can’t afford your product or aren’t the right fit.
Example
- Unfocused Copy (Attracts Wrong Audience): “The best CRM for all businesses.”
- Optimized Copy (Defines SAM Clearly): “The AI-powered CRM designed for solopreneurs & small teams who want more sales without the admin hassle.”
Well-crafted copy ensures you only attract potential buyers, refining your SAM and making marketing more cost-effective.
3️⃣ Copywriting Turns SOM Into Paying Customers
SOM is where the money is made.
This is the part of the market where your marketing, sales, and execution turn potential leads into real customers.
💰 The RIGHT copy turns SOM into $$$ by –
→ Highlighting your unique value proposition (why you over competitors?)
→ Making your CTA irresistible (so they take action)
→ Speaking your audience’s language (so they feel understood)
Example
- Weak SOM Copy (Loses Customers): “Our CRM has the best AI features.” (Too vague)
- Strong SOM Copy (Converts Customers): “Ditch the manual work. Automate lead tracking, follow-ups & sales with AI—so you close deals 5x faster.” (Clear benefit + urgency)
When your copywriting aligns with sales psychology, your SOM becomes your paying customer base.
Why This Matters for Business Growth
Still wondering if copywriting actually affects revenue?
Let’s put it this way –
→ If your copy expands TAM, more people know about you.
→ If your copy refines SAM, you attract the right leads.
→ If your copy converts SOM, you increase sales & revenue.
Real-World Example
👉 A SaaS company rewrote their landing page copy to clarify their unique benefits & audience fit
Result? 47% more conversions.
👉 A DTC eCommerce brand improved their product descriptions to highlight emotions & urgency
Result? 32% more purchases.
👉 A service business optimized their email copy with stronger CTAs & personalization
Result? 56% increase in booked calls.
See the pattern? Your words make the sale.
Are You Writing Copy That Sells?
Copywriting is not just words…
It’s business strategy.
↪ It defines WHO sees your brand (TAM).
↪ It attracts the RIGHT customers (SAM).
↪ It turns them into paying clients (SOM).
If your copy isn’t doing these three things, you’re leaving money on the table.
