What's the average cost for building a website?

There is no single “average” that helps, because websites vary by complexity and goals. A simple site is mostly structure, design polish, and content. A growth site includes conversion UX, SEO structure, performance work, integrations, and often multiple landing pages. Ecommerce adds product data, checkout considerations, analytics, and ongoing iteration. Instead of chasing averages, define your use case: brochure, lead gen, ecommerce, or platform. Then estimate based on page count, functionality, and content readiness. That produces a real budget, not a misleading number.
