What is total addressable market (TAM)?
Key Takeaways:
- You need to know your total market size before scaling marketing spend.
- If your current market isn’t fully captured, expanding may reduce ROI.
It helps you understand how much more potential exists within your current geographic scope.
Trying to expand too soon without fully exploring this audience can lead to wasted ad spend.
How do you calculate your TAM?
Define your ideal customer. Then estimate how many of them exist in your local or national region.
You can use government census data, third-party research, or your own analytics tools to estimate TAM.
If you haven’t tapped into all of it yet, optimize before expanding.
Should I improve my current marketing before expanding?
Key Takeaways:
- Optimizing your current marketing brings higher ROI than immediate expansion.
- Weak funnels will cost more if scaled without fixing first.
You must improve what already exists—offers, messaging, ad targeting, and conversion rates.
Focusing on what’s already working is often more profitable than expanding to new and uncertain audiences.
What should you optimize first?
- Conversion rates on landing pages
- Audience targeting and messaging in ads
- Email or remarketing flows
- Performance across existing channels
Can your business operations support more demand?
Key Takeaways:
- You must verify logistics and fulfillment capacity before increasing spend.
- Customer experience can suffer if backend systems are not ready for scale.
Scaling only makes sense if your operations can match the new demand.
What should you check before scaling?
- Do you have inventory, team, or automation to fulfill more orders?
- Will delivery time and quality stay consistent with double the demand?
- Is your customer support ready for more inquiries across more time zones?
Will your offer work in a new market?
Key Takeaways:
- Not all offers perform the same across regions or demographics.
- Test your offer in a small campaign before launching full-scale.
Your offer might need adaptation before it performs as well in a different location.
How do you test an offer?
- Run small paid campaigns in the new region
- Track conversion and cost per acquisition
- Use feedback to refine the offer before scaling spend
Quick summary: When is it worth expanding marketing spend?
- You know your total addressable market and haven’t tapped all of it yet.
- Your current marketing campaigns are fully optimized and converting well.
- Your backend systems—delivery, support, and fulfillment—can scale up.
- Your offer has been tested and performs well in the new region or demographic.
If you can’t say yes to all four, you may waste money by scaling too soon.
