The Ultimate Domain Name Handbook
The Ultimate Domain Name Handbook by David Clements is a comprehensive resource for understanding domain names as strategic business assets. Published in January 2025, the 23-chapter, 72,000-word guide distills Clements' two decades of experience helping businesses and investors navigate domain acquisitions and sales. The book addresses fundamental questions like what makes a great domain name, how to acquire domains that aren't for sale, how to determine premium value, and strategies for selling high-value domains. Topics include domain branding strategies, industry basics, intellectual property protection, and best practices for buying, selling, and investing in domains, all illustrated with extensive case studies and real-world examples. Clements created the handbook as a single comprehensive reference after repeatedly having the same conversations with business owners who were missing opportunities by not securing the right domain names for their brands. The book positions itself as essential reading for founders building online brands, corporate marketers, and anyone looking to invest in domain names as assets.
