Resume keywords are the difference between a 40% ATS score and an 85% ATS score — and consequently, between silence and a callback. But not all keywords are equal. This guide explains which types matter, how to find the right ones, and where to place them.
The three types of resume keywords
1. Hard skill keywords
Specific, verifiable skills — programming languages, software tools, certifications, methodologies. Examples: Python, Salesforce, GAAP, Agile, Kubernetes. These are weighted most heavily by ATS because they're unambiguous.
2. Soft skill keywords
Communication, leadership, collaboration. These matter, but they need to be backed by evidence in your bullets rather than just listed. "Led a cross-functional team of 8" is more powerful than just listing "leadership".
3. Industry and role keywords
Phrases specific to your field: "full-stack development", "patient-centered care", "revenue forecasting", "regulatory compliance". These tell the ATS and recruiter that you understand the domain.
Where to find keywords for any job
The job description itself
Obvious but underused. Read it three times. Note every noun phrase in the Requirements and Responsibilities sections — mirror these verbatim.
3–5 similar job postings
Search for the same role at 4–5 different companies and identify the keywords that appear across all of them. These are the universal requirements — non-negotiable for your Skills section.
LinkedIn profiles of people in the role
Look at profiles of people who currently hold the title. Their Skills sections and Experience bullet language reveal what the industry actually uses.
An ATS checker
Paste your resume and the job description into Rezly — it surfaces the exact keywords that are present in the job description but missing from your resume.
Where to place keywords on your resume
ATS parsers weight different sections differently. In rough order of importance:
- Summary — high weight, read first by both ATS and humans
- Skills section — directly indexed by most ATS systems
- Job title fields — some ATS give elevated weight to title matches
- Experience bullets — context demonstrates the keyword, not just lists it
- Education — relevant coursework and thesis topics count
Keyword density: how much is too much?
There's no precise formula, but a useful heuristic is: if the resume sounds like a keyword list when read aloud, you've gone too far. Aim for each keyword appearing 1–2 times, naturally integrated into sentences and bullets. Stuffing keywords into a white-font invisible block was an old trick — modern ATS systems and recruiter review have made it counterproductive and potentially harmful.
