Resume keywords for ATS: what actually matters
Most keyword advice imagines the ATS as a bouncer with a checklist. The reality is simpler and less scary: the ATS extracts your text and ranks relevance against the posting, and the recruiter searches within it. You need the right terms present and provable, not stuffed.

Where keywords come from: the job description itself, not a master list. The 8–12 nouns and verbs the posting repeats (tools, skills, domain terms, the role title) are the vocabulary you will be matched against. A generic "500 best keywords" list is noise by comparison.
Where keywords need to appear: in your skills section and inside real experience bullets. A skill that exists only in a comma-separated list is weak evidence; a skill inside a bullet with an outcome ("built ETL pipelines in Airflow feeding 40 dashboards") counts double: for the parser and for the human.
The acronym rule: write both forms at least once, "Applicant Tracking System (ATS)", "Search Engine Optimization (SEO)". Parsers and recruiter searches are inconsistent about which form they use, and you want to match either.
The density myth: there is no magic keyword percentage, and past a point, repetition works against you. Recruiters recognize stuffing instantly: white-text tricks and keyword walls get applications binned, not ranked. Aim for coverage of the JD’s core terms, roughly 60% overlap, each one attached to evidence.
The honest constraint: only add a keyword you can defend. Matching the JD’s vocabulary for work you actually did is tailoring. Adding "Kubernetes" because the JD wants it is a fabrication that one interview question will find.
