Key Takeaways

  • 1Avoid keyword stuffing: replace repeated keywords with contextual, outcome-driven sentences to pass both ATS and human reviewers.
  • 2Perform a quick 5-step keyword audit: collect job postings, build a weighted keyword list, check frequency, add semantic variants, and verify readability.
  • 3Place high-priority keywords strategically: header, first 100 words of your summary, top bullets of experience, and a concise skills section.
  • 4Use semantic and long-tail phrases (e.g., “B2B SaaS onboarding playbook”) to increase relevancy and reduce competition.
  • 5Follow an efficient process (30–45 minutes per application) and use tools like Resumize.ai to automate extraction and optimize phrasing.
  • 6Keep formatting ATS-safe: standard headers, bullet points, no images or text boxes, and plain-text previews before sending.
  • 7Measure and iterate: track responses, A/B test summaries, and refine keyword placement based on recruiter feedback.

Conclusion

Frequently Asked Questions

No. Quantity doesn’t guarantee relevance. Modern ATS uses semantic matching and places weight on context. Focus on relevant keywords placed in meaningful, measurable achievement statements rather than repeating terms indiscriminately.
There’s no strict number, but aim to include high-priority keywords in your header/summary, 2–3 experience bullets, and the skills section. Avoid repeating the same phrase more than 3–4 times without context; instead use synonyms and related terms.
Tools accelerate research and provide data-driven suggestions, but they don’t replace human judgment. Use Resumize.ai to extract keywords and test ATS compatibility, then refine phrasing to reflect your true accomplishments and voice.
Yes — and you should. Tailoring increases relevance and match rates. Use a base template and spend 30–45 minutes tailoring summary and top bullets to include high-priority keywords from each posting.
