"Everyone" is not a target audience.
Direct answer
Define your target audience by describing who has the problem, what they need, where they spend time and how they make decisions. Start narrow, test with interviews and expand later.
A simple profile
- Who: role, situation.
- Problem: what frustrates them.
- Goal: what they want.
- Where to find them: communities, platforms.
- Alternatives: what they use now.
Example
"Solo accountants who spend several hours a week chasing client documents."
