To attract customers: Even if you have a great product or service, people won’t know about it without marketing.

To build brand awareness: Marketing helps you create a clear and recognizable identity for your project or business.

To compete in the market: With so many options available, marketing helps you stand out from the competition.

To drive sales and growth: Campaigns, promotions, and social media engagement help convert interest into actual sales.

To gather feedback and improve: Marketing channels—especially digital—allow you to understand customer needs and adjust your offering accordingly.

Are there exceptions? Not really, but small local or family businesses might rely mainly on word-of-mouth. Government or monopoly-type services may not need traditional marketing but still benefit from public communication and awareness.

In summary: Having no marketing strategy means relying on luck—and that's not a safe approach for any serious project.
