Optimize resume keywords for applicant tracking systems (ATS). Part of the DevTools Surf developer suite. Browse more tools in the Career & Professional collection.
Use Cases
Identify missing keywords from a job description before submitting an application.
Score a resume's keyword density against a specific job posting.
Reformat a design-heavy resume into ATS-compatible plain text.
Tailor a single base resume for multiple roles by swapping in role-specific keywords.
Tips
Mirror the exact phrasing from the job description — ATS systems match literal strings, not synonyms. 'Project Management' and 'Managing Projects' may not match the same filter.
Place high-priority keywords in the first 100 words of the resume — some ATS systems weight earlier mentions more heavily.
Remove tables, headers/footers, and text boxes before ATS submission — most parsers cannot extract text from these elements reliably.
Fun Facts
Over 75% of large companies (500+ employees) use Applicant Tracking Systems (ATS) to filter resumes before any human reviews them, per a 2021 report by Jobscan.
The first commercial ATS was Restrac, launched in 1988. By the mid-2000s, ATS had become standard practice at enterprise companies.
Studies by Harvard Business Review (2021) found that ATS filters reject up to 27% of qualified candidates due to formatting or keyword mismatches — not lack of qualifications.
FAQ
What are the most important sections for ATS parsing?
Work experience job titles, company names, dates, and skills sections are the highest-weight fields for most ATS. Education field parsing is also strong. Certifications and summary sections vary by system.
Should I keyword-stuff my resume?
No — keyword density that reads unnaturally is penalized by some modern ATS systems and is immediately obvious to human reviewers. Integrate keywords naturally into bullet points describing actual accomplishments.
