Customer Service Resume Keywords & ATS Skills
Customer service resumes are filtered by the support platform you know and the operational vocabulary the team runs on. The keywords that carry the most weight are the helpdesk you worked in (Zendesk, Salesforce Service Cloud, Freshdesk), the process terms the posting lists (ticket management, SLA compliance, escalation), and the metrics a support team is measured on (CSAT, first call resolution, average handle time). Spell out the acronyms once and use the platform names exactly as the company writes them.

Where to place these keywords
Name the support platform in your experience bullets ("resolved 60+ tickets daily in Zendesk") rather than in a generic skills list, then use the metrics the posting names — CSAT, FCR, AHT, SLA — with your actual numbers beside them.
Customer Service resume keywords FAQ
Which customer service keywords matter most for ATS?+
The support platform (Zendesk, Salesforce Service Cloud, Freshdesk), the channel you handled (phone, live chat, email), and the process terms in the posting — ticket management, escalation, SLA compliance. Add the metrics the employer lists, such as CSAT or first call resolution.
Should I include metrics like CSAT and AHT on my resume?+
Yes, if the employer measures them — and most support teams do. "Maintained 95% CSAT across 60+ daily tickets" proves the skill with evidence. Only use numbers you can defend in an interview.
Do I need to list every CRM or helpdesk tool?+
No. Feature the platform the posting names and that you used day to day; group the rest in one line. A recruiter scanning for Zendesk experience will miss a tool buried in a 20-item list.
