You tailor your resume, paste in the right skills and hear nothing back. Applicant tracking system keywords work by matching the exact wording of a job posting against your resume, so mine the posting and mirror it truthfully.
If you are still shaping your wider approach, our guide on how to start a job search puts keyword work in context. This article covers the mechanics, the common myths, a worked method for mining a posting, and a way to check the result.
How applicant tracking system keywords work
An applicant tracking system (ATS) is software that many employers use to collect, rank, sort and review resumes before a recruiter or hiring manager does, according to UT Austin career services. It compares your resume with the position description you applied for and ranks candidates by perceived qualification. The keywords are the terms in that posting that the comparison depends on.
Many systems also include a resume scanner, a feature that pulls out details such as work experience, contact details, software and academic background, as described by Jobillico. A term the scanner cannot read cannot be counted, which is why layout matters as much as wording.
Matching is based on wording. When a posting lists “Warehouse management system (WMS)”, the ATS may scan for WMS, warehouse and management. Some systems use natural language processing to recognise synonyms, for example linking WMS to inventory management software or a logistics management platform. Keywords also do not carry equal weight, because some score more points than others depending on the job’s requirements (Jobillico).
The practical judgement: use the posting’s own words first, because exact matching is the safest case. Treat synonym recognition as a bonus rather than a plan. IFG goes further and advises including the exact keywords from the posting rather than substituting synonyms.
Common misunderstandings about ATS keywords
Most keyword mistakes come from a handful of beliefs about what the software does. The table sets each belief against what the evidence supports.
| Common belief | What is supported | Planning use |
|---|---|---|
| The ATS decides who gets hired | It collects, ranks, sorts and reviews resumes before a recruiter or hiring manager does, ranking by perceived qualification against the posting | Write for the posting first, then for the person who reads your resume after the ranking |
| More keywords always means a higher score | Some keywords score more than others, and throwing keywords around randomly is called a red flag practice | Prioritise the terms the posting stresses and use each one in context |
| A synonym is as good as the posting’s word | The ATS may scan for exact words, although some systems use natural language processing to recognise synonyms | Use the posting’s exact term and place any variant beside it |
| Any attractive design is safe | Tables, columns, graphics, objects, LaTeX coding and design websites such as Canva are listed as formatting to avoid | Keep a plain, single-flow document |
These points draw on UT Austin career services and Jobillico.
Mining a job posting for keywords
A posting is the most reliable keyword source you have, because the ATS compares your resume against it. Work through it in a fixed order so nothing is guessed.
- Choose a specific posting. Matching can only evaluate what the requirements actually say, so a detailed posting gives you a better list than a vague one (HireTrace).
- List the terms and mark repeats. UT Austin’s guidance is to list the keywords in the description with emphasis on which are repeated most. A LinkedIn career guide puts it simply: if it is repeated, it is important.
- Sort into experience and skills. Group the terms as experience-related keywords and skills-related keywords, and mirror the pattern the posting uses. Add technical certifications and the industry-standard software the job names (Jobillico).
- Separate must-haves from preferences. Specific technical skills or certifications that the posting requires belong ahead of preferred qualifications (HireTrace). Your final list should start with these.
- Check each term against your history. Incorporate only the keywords that match your experience. A term you cannot back up with real work will not survive a human read.
Applied to the warehouse example, the must-have term is the system itself. Writing it as “warehouse management system (WMS)” covers the full phrase and the abbreviation in one place, an approach IFG recommends when it suggests both the full words and abbreviations, or a common industry term in parentheses.
Where to place keywords on your resume
Keywords should fit naturally within the context of your resume sections, such as the skills list, professional summary, achievements and experience (Jobillico). Each location does a different job.
- Summary near the top. A summary or professional objective is an ideal place for the specific job title you are targeting (IFG).
- Skills section. Use it for the tools, software and certifications from your must-have list, spelled as the posting spells them.
- Experience bullets. Put the strongest terms where they sit beside real duties and results, because that is where a human reviewer checks them.
- Restraint. Do not cram as many keywords as possible into every section; place them organically (IFG).
A before and after pair from the LinkedIn guide shows the difference in an experience bullet:
- Before: Managed projects and worked with teams.
- After (illustrative): Led project management initiatives and managed stakeholder engagement, improving delivery timelines by 15%.
The rewrite names the work in terms a posting would use and attaches an outcome. Keep a figure like that only if it reflects your own results; the number belongs to the guide’s example, not to your resume.
File format and layout
Keywords only count if they can be read. A LinkedIn career guide warns against hiding keywords in images, since the ATS cannot read them. UT Austin career services lists tables, columns, graphics, objects, LaTeX coding and resume design websites such as Canva as formatting to avoid.
The same university suggests making a resume ATS-friendly by starting from its own Word doc and Google doc templates. If you want a safe starting point, a plain word-processor document with ordinary headings is the supported choice. Decorative layouts suit a printed copy for a person, not the file you upload.
Testing your resume before you apply
Testing is a two-part check: whether the terms are present, and whether a scanner could read them.
- Term check. Take your ranked list from the posting and tick off every must-have term in your resume, in the posting’s wording, inside a section where it belongs.
- Readability check. The resume scanner extracts work experience, contact details, software and academic background, so confirm those appear as ordinary text and not inside graphics or objects.
- Score check. AI chatbots that simulate ATS processes can give an instant ATS score for a resume, according to Jobillico.
Treat any score as a prompt to revisit the posting and your list, not as a verdict. A simulator is not the employer’s own system, and the check that matters is whether your must-have terms appear honestly and readably.
After the resume: interviews and offers
Strong keywords earn the read, not the job.

Frequently asked questions
| Question | Answer |
|---|---|
| What types of terms count as ATS keywords? | They are specific terms that reflect the role’s requirements: job titles, skills such as data analysis or stakeholder management, tools such as Excel or Salesforce, certifications such as PMP or CIPD, and industry terms, as listed in a LinkedIn career guide. |
| Is a chronological or functional resume better for ATS? | Chronological. UT Austin career services says both ATS and recruiters work better with experience organised chronologically. |
| Should I use the same resume for every application? | No. The same university advises resaving your master resume as a new document each time you apply and tailoring it to that job. |
| What if the job posting is vague? | Matching can only evaluate what the requirements say (HireTrace), so a vague posting gives fewer reliable terms. Build your list from the specific skills, tools and certifications it does name. |
