• Keyword Relevance: Domains like CarInsurance.com and Insurance.com align with high-demand industries, ensuring traffic and brand authority.

• Memorability and Brevity: Short, catchy names like Voice.com or Chat.com are easy to remember and type, boosting their value.

• Industry Trends: Sectors like AI, fintech, and online betting drive demand for relevant domains (e.g., AI.com, Bet.bet).

• Scarcity: Premium .com domains are finite, increasing competition and prices.
