Good Customer Service Keywords to Include

Beyond tools and metrics, good customer service keywords also cover the personal qualities recruiters and ATS systems scan for in support roles. These personal keywords for customer service signal how you work with people, not just which systems you know:

• Interpersonal traits: patience, empathy, active listening, adaptability, positive attitude, reliability, teamwork, emotional intelligence
• Communication skills: clear verbal communication, written communication, tone management, rapport building, cross-cultural communication
• Problem-solving orientation: critical thinking, resourcefulness, ownership, follow-through, attention to detail, time management under pressure

Pair these personal keywords with a quantified result so they read as evidence, not adjectives: "Resolved 95% of customer complaints on first contact by combining active listening with clear, empathetic communication" is far stronger than listing "empathy" and "patience" on their own.
