Why Marketing is More Critical Than Your Product
Before diving into feature comparisons, it's crucial to understand this: Marketing is harder than building the product. While crafting a product or service is a core component of any business, your startup will only succeed if customers can find and engage with you. SEO tools like SEMrush and SimilarWeb empower startups to:
- Validate their ideas: Understand search demand for your niche before you even launch.
- Outpace competitors: Spy on rivals’ strategies to uncover untapped opportunities.
- Build authority: Use keyword optimization and backlinks to grow your domain authority (DA).
