IT support has a title problem: the same job is posted as help desk technician, service desk analyst, desktop support, IT support specialist, or technical support engineer. ATS searches often include the title itself — so if your resume says "help desk" and the employer says "service desk", you can lose a match on pure vocabulary.
The fix is deliberate keyword mirroring, plus the systems and certifications that anchor support searches. Check your resume free below.
Use the employer's job title, verbatim, at least once — ideally in your summary line: "IT support specialist with 4 years on a 3-person service desk supporting 600 users." Where your official title differed, list both: "Help Desk Technician (Service Desk / Desktop Support)". Support recruiters know titles vary, and matching their vocabulary costs you nothing.
Ticketing and management systems are the other anchor keywords: ServiceNow, Zendesk, Jira Service Management, Freshdesk, Intune, Active Directory, Entra ID (Azure AD), Microsoft 365. Name every system you've worked in daily. "Administered Active Directory and Entra ID for 600 users — onboarding, offboarding, group policy" earns three or four keyword matches in one honest sentence.
Support is one of the most measurable jobs there is, so use the metrics: tickets resolved per week, first-call resolution rate, SLA compliance, CSAT. "Resolved ~50 tickets/week at 92% first-call resolution, within SLA 98% of the time" tells a hiring manager your level faster than any adjective — and 'SLA' and 'first-call resolution' are themselves searched terms.
Certifications matter most early in a support career, and they're searched literally: CompTIA A+, Network+, Security+, ITIL Foundation, Microsoft (MS-900, AZ-900). Write them exactly, in a Certifications section — 'CompTIA A+' with the vendor name, since some searches include "CompTIA" and some just "A+".
Paste your resume — and the job description if you have one — and get an instant ATS score with the exact keywords you're missing and what to fix first.

After 2–3 years, experience with specific systems (ServiceNow, Active Directory, Intune) outweighs certificates — but certifications remain cheap keyword matches, so keep them listed and current either way.
Estimate honestly from what you know: rough tickets per day, users supported, systems administered. 'Supported ~400 users across two offices' is a legitimate, verifiable-in-conversation claim. Avoid inventing precise percentages you can't back up in an interview.
A certification (usually CompTIA A+), a skills section naming real systems you've used (Microsoft 365, Windows, basic networking), and any support-adjacent experience reframed honestly — internal tech point-person, POS troubleshooting, lab support. The screen filters on those keywords, not on your previous job title.
