You can make money by flipping domain names by buying popular keywords and reselling them at a profit.

Domain flipping involves buying desirable domain names with the goal of selling them later at a profit. To start, research popular or niche keywords that may be in demand, then check availability on domain marketplaces like GoDaddy, Namecheap, or Flippa. Register domains that are short, memorable, or keyword-rich. After acquiring a portfolio, list your domains for sale on platforms like Sedo or Afternic. Buyers interested in specific industries or brandable names may pay a premium. With research and patience, domain flipping can become a profitable side hustle, although competition and demand can vary widely based on the domain's appeal and relevance.
