Conclusion

Frequently Asked Questions

No universal limit exists, but a practical target is 8–20 unique, relevant keywords. Focus on matching required skills and showing proof in your experience. Excessive repetition or irrelevant keywords can hurt more than help.
Some older ATS can't detect stuffing but modern systems and human reviewers can. Keyword stuffing damages readability and credibility; it may lower your score if it creates unnatural language or no supporting evidence.
Prioritize required qualifications and frequently repeated terms. Pick 8–12 that align with your experience and group them by section (title, summary, skills, experience). Use company language and measurable achievements to strengthen relevance.
Tools accelerate the process by extracting keywords and suggesting tailored lines, but you should always review and personalize output. Combine automation with human judgment to ensure accuracy and authenticity.
