ATS Keywords: What They Are and How to Beat the Bots

You applied to 50 jobs and heard back from two. It is not your experience. It is probably the ATS. Over 90% of large companies and a growing number of mid-size firms use applicant tracking systems to screen resumes before a human ever sees them. If your resume does not pass the automated filter, it does not matter how qualified you are.

What is an ATS?

An applicant tracking system is software that companies use to manage the hiring process. When you submit your resume online, it goes into the ATS first. The system parses your document, extracts information, and compares it against the job requirements. If your resume does not match well enough, it gets deprioritized or rejected automatically.

Common ATS platforms include Workday, Greenhouse, Lever, and iCIMS. Each works slightly differently, but they all rely on the same core concept: keyword matching.

How keyword matching works

When a recruiter creates a job listing, the ATS identifies required skills, qualifications, and experience from the description. It then scans incoming resumes for those same terms. The closer your resume matches the job description's language, the higher you score.

This is not just about hard skills. ATS systems look for:

• Hard skills: Python, SQL, project management, financial modeling
• Soft skills: leadership, communication, cross-functional collaboration
• Certifications: PMP, CPA, AWS Certified, Six Sigma
• Job titles: matching or closely related titles to the open role
• Industry terms: specific jargon relevant to the field

How to optimize your resume for ATS

The good news is that ATS optimization is straightforward once you understand the rules.

1. Use the exact terms from the job listing. If the posting says "data analysis," write "data analysis," not "analyzing data" or "data analytics." ATS systems can be literal.
2. Include a skills section. A dedicated skills section gives the ATS a clear list to match against. Include both technical and soft skills mentioned in the listing.
3. Use standard formatting. Avoid tables, columns, images, and unusual fonts. Many ATS systems cannot parse complex layouts. Stick to a clean, single-column format with standard headings like "Experience," "Education," and "Skills."
4. Spell out acronyms. Write "Search Engine Optimization (SEO)" the first time, then use the acronym. Some systems only recognize one form.
5. Submit as PDF or DOCX. Most modern ATS systems handle both, but check the application instructions. When in doubt, use PDF for consistent formatting.

What not to do

Do not try to game the system with white text or hidden keywords. ATS platforms have caught on to these tricks, and if a recruiter discovers it, your application is done.

Do not copy-paste the entire job description into your resume. The goal is to naturally incorporate relevant keywords into your actual experience. If you cannot honestly claim a skill, leave it out.

Check your score before applying

The smartest approach is to check your ATS compatibility before you submit. Run your resume against the job listing and see which keywords you are missing. Then update your resume to fill the gaps where your experience genuinely applies.

This takes the guesswork out of the process. Instead of hoping your resume passes the filter, you know exactly where it stands and what to fix.
