ATS keywords: what applicant tracking systems scan for
The words an Applicant Tracking System matches your resume against.
Definition
ATS keywords are words and phrases (often skills, tools, methodologies) that an Applicant Tracking System looks for in your resume to determine fit. They come from the job description, and recruiters also type them into the ATS search when they look for candidates. Many systems still match literally: your "cross-functional collaboration" may not register as the posting's "stakeholder management", even though they mean the same thing.
Example
A JD says: "Build and maintain ETL pipelines using Python, dbt, and Snowflake; perform cohort and retention analysis." The ATS keywords are: ETL pipelines, Python, dbt, Snowflake, cohort analysis, retention analysis. If your resume says "data pipelines" instead of "ETL pipelines," the ATS doesn't score the match.
Why it matters
An ATS ranks and filters applicants by how well their resume matches the posting, and recruiters search the same database by keyword. Using the posting's own words for the skills you really have is the most direct way to show up in both. The hard part isn't knowing what to mirror. It's doing it for every application without rewriting your bullets from scratch each time.
The three kinds of ATS keywords
Not every word in a job description is a keyword. The ones that actually get matched fall into three buckets:
- Hard skills & tools — the literal technologies, software, and methods: Python, SQL, Salesforce, Workday, dbt, GAAP, Scrum, Power BI, Figma, Kubernetes. These carry the most weight because they're unambiguous.
- Role & certification terms — titles, credentials, and domain language: CPA, PMP, registered nurse, financial modeling, demand generation, supply chain, stakeholder management.
- Action + outcome phrases — the exact verbs and results the JD repeats: “led cross-functional,” “reduced churn,” “built ETL pipelines,” “owned the roadmap.” Mirror the phrasing, not a synonym of it.
ATS keywords list by role
There's no universal list. The right ATS resume keywords are the ones in your target job posting. But these terms come up again and again in postings for common roles, so they show the kind of vocabulary an applicant tracking system will be matching:
- Software engineer: Python, Java, JavaScript, React, AWS, Docker, Kubernetes, CI/CD, REST APIs, microservices, Agile
- Data analyst: SQL, Python, Tableau, Power BI, dbt, ETL, data modeling, A/B testing, cohort analysis, stakeholder reporting
- Business analyst: requirements gathering, process mapping, BPMN, user stories, gap analysis, UAT, SQL, stakeholder management
- Product manager: product roadmap, user research, backlog prioritization, A/B testing, OKRs, go-to-market, Jira, cross-functional
- Project manager: PMP, Agile, Scrum, stakeholder management, risk management, scope, schedule, budget management, Jira, MS Project
- Marketing manager: SEO, SEM, demand generation, marketing automation, HubSpot, Google Analytics, content strategy, lifecycle marketing, attribution
- Sales representative: B2B sales, prospecting, pipeline management, Salesforce or HubSpot CRM, quota attainment, negotiation, account management
- Customer service representative: customer satisfaction, CRM, Zendesk, ticketing, de-escalation, first-contact resolution, bilingual (English/French)
- Administrative assistant: calendar management, Microsoft 365, Outlook, scheduling, data entry, minute-taking, travel arrangements, office coordination
- Accountant: CPA, month-end close, reconciliations, accounts payable and receivable, IFRS, ASPE, GST/HST, QuickBooks, Excel
- Financial analyst: financial modeling, forecasting, variance analysis, FP&A, budgeting, Excel, month-end close, IFRS
- HR generalist: HRIS, Workday, onboarding, employee relations, full-cycle recruitment, employment standards, payroll, CHRP or CHRL
- Operations manager: process improvement, Lean, Six Sigma, KPIs, supply chain, vendor management, budgeting, P&L
- Registered nurse: BLS, ACLS, patient assessment, EMR/EHR, Epic or Meditech, care planning, medication administration, registration with your provincial nursing college
Treat it as a vocabulary primer, not a copy-paste list. A resume scanner only credits the keywords that match the specific job you're applying to, and only claim the skills you actually have.
Where to put ATS keywords on your resume
- Skills section: the tools, methods and certifications from the posting, in the posting's wording.
- Experience bullets: the same keywords used in context, with what you did and the result. This is what a recruiter reads after the ATS surfaces you.
- Summary and title line: the job title from the posting, if it honestly describes you, and your two or three strongest matching skills.
How to find the ATS keywords in a specific job posting
- Pull the must-haves first. Anything in “Requirements” or repeated 2+ times in the JD is almost certainly a scored keyword.
- Match exact wording. If the JD says “stakeholder management,” write “stakeholder management” — not “cross-functional collaboration.” The parser does literal matching.
- Cover both the spelled-out term and the acronym (e.g. “Search Engine Optimization (SEO)”) — different ATS configs match different forms.
- Put them where they're weighted: a dedicated Skills section plus woven naturally into your experience bullets. Avoid keyword stuffing — modern parsers and recruiters both penalise it.

Frequently asked questions
What are ATS keywords?
ATS keywords are the skills, tools, qualifications and phrases in a job posting that an applicant tracking system looks for in your resume. The closer your resume matches them, in the posting's own wording, the higher it ranks when the ATS filters applicants and when recruiters search.
Is there one list of ATS keywords that works for every job?
No. Each ATS matches against the specific posting, so the keywords that count are the ones in that job description. Lists by role, like the one on this page, show typical vocabulary, but you still need to check each posting.
How many keywords should my resume include?
There is no fixed number. A practical check: every skill or tool listed under "requirements" that you actually have should appear somewhere on your resume, in the same words the posting uses, ideally inside a bullet that shows how you used it.
Do applicant tracking systems understand synonyms and acronyms?
Some newer systems match common variants, but many still rely on literal matches, and you can't tell which one an employer uses. Use the posting's exact term, and write out an acronym once alongside it, for example "search engine optimization (SEO)".
Where should ATS keywords go on a resume?
In your skills section, in your experience bullets where you show how you used them, and in your summary or title line. Listing keywords without context, or hiding them in white text, is keyword stuffing and tends to hurt you once a recruiter reads the resume.
