Focus on what you do, how you help your customers, and the best way to get in touch (your call to action).
Write in the first person, avoid bullet points, and make the skills and experience you talk about directly relevant to your current job. Most importantly, write with the customer in mind.
For example, “I close million-dollar deals” is good for a résumé, but “I save clients millions of dollars” is better if you’re not in the job market.
