Quick answer
Look for a product with a real, specific problem it solves, evidence that people already search for or buy similar things, a manageable cost to source or make, and something you can explain in one sentence. A product that fails all four is worth reconsidering.
Choosing what to sell is less about finding a clever idea nobody has thought of, and more about finding a real, specific need with evidence that people already spend money solving it.
Start with a problem, not an idea
A product built around a specific problem someone actually has explains itself. A product built around "this seems interesting" usually needs convincing.
Look for existing demand
Evidence that people already search for, discuss, or buy something similar is a stronger signal than your own instinct that it should sell. Existing demand means you are not trying to create a need from scratch.
Check the real cost to source or make it
Get an honest number for what the product actually costs you, including materials, packaging, and your time, before assuming the margin works.
The one-sentence test
If you cannot describe what the product is and who it is for in one clear sentence, it may need more focus before you commit to it.
Avoid an oversaturated category with no angle
A crowded category is not automatically a bad sign, but entering one with nothing different to offer usually means competing on price alone, which is a hard place to start from.
Start narrower than feels natural
A specific product for a specific person is easier to market and easier to judge honestly than a broad "something for everyone" offering.
Practical example
Someone considering "home decor" narrows it down to a single specific product, small ceramic planters sized for apartment windowsills, after noticing repeated posts in local groups asking where to find exactly that. The narrow focus makes the first product decision much easier than the broad category ever was.
Common mistakes
Action checklist
- Identify the specific problem your product solves.
- Look for evidence people already want something similar.
- Calculate the real cost to source or make it, honestly.
- Write a one-sentence description of the product and who it is for.
- Narrow the idea until it is specific, not broad.
FAQ
Is it bad to enter a category with a lot of existing sellers?
Not necessarily. Existing sellers are evidence of real demand. The question is whether you have a genuine angle, not whether competition exists at all.
