ATS keywords are the specific terms, phrases, skills, tools, and qualifications that Applicant Tracking Systems scan for in resumes. They come directly from the job description — the employer has already told you exactly what they want. Your job is to make sure those words appear in your resume.
ATS systems don't understand meaning — they match strings. If a job requires "Python programming" and your resume says "scripting," the system may not connect them. This is why using the exact language from the job description matters more than you might expect.
Keywords fall into four categories: hard skills (technical abilities, tools, software), soft skills (communication, leadership, collaboration), action words (verbs like managed, led, delivered), and qualifications (certifications, degrees, accreditations).
Start with the Job Description
Read the full JD carefully. Highlight every skill, tool, qualification, and responsibility mentioned. Repeated terms are almost always ATS keywords.
Use a Keyword Extractor
Paste the job description into HireSprint's free keyword extractor. It automatically identifies hard skills, soft skills, action words, and qualifications — grouped by category.
Compare Against Your Resume
Check each keyword against your resume. Missing ones need to be added — but only if they genuinely describe your experience. Never fabricate.
Incorporate Naturally
Add keywords in context within your bullet points and summary. "Managed Python-based data pipelines" is better than adding Python to a skills list if you can demonstrate it.
Check Your ATS Score
Run your updated resume through HireSprint's free ATS checker. See your score, identify remaining gaps, and fix them before applying.
Different industries have different keyword priorities. These are the most commonly scanned resume keywords by industry in 2025 — incorporate the ones that genuinely match your experience.
These are general starting points. Always prioritise keywords from the specific job description you are applying to — they are more valuable than generic industry keywords.
The goal is to pass ATS screening while also compelling the human reader. Keyword stuffing — listing 30 terms in a skills section with no context — often fails both tests. Here is how to incorporate keywords naturally:
Professional Summary
"Results-driven data engineer with 5 years of experience building Python and Spark pipelines on AWS. Delivered 40% reduction in data processing costs through architectural optimisation."
Work Experience Bullets
"Engineered a microservices architecture using Docker and Kubernetes, reducing deployment time from 2 hours to 8 minutes."
Skills Section
Group by category: Languages: Python, SQL, TypeScript | Cloud: AWS, GCP | Tools: Terraform, GitHub Actions, DataDog
ATS (Applicant Tracking System) keywords are the specific words and phrases that hiring software scans your resume for. They are drawn directly from the job description — the skills, tools, qualifications, and responsibilities the employer listed. If your resume lacks these keywords, it may be filtered out before a human ever reads it.
Start with the job description. Read it carefully and identify: (1) repeated words and phrases, (2) required skills and tools, (3) job title variations, (4) industry-specific terminology. Use HireSprint's free keyword extractor to automate this process — paste the JD and get the top keywords instantly.
Aim for 15–25 relevant keywords, used naturally in context. Do not keyword-stuff — modern ATS systems are sophisticated enough to detect it, and over-optimised resumes look unnatural to human reviewers. Focus on incorporating keywords in your work experience bullet points, not just listing them in a skills section.
The most impactful places are: (1) your professional summary/objective, (2) your work experience bullet points, (3) your skills section, (4) job titles if accurate. Keywords in your summary and recent experience bullets are weighted most heavily by ATS systems.
