Optimisation vs stuffing — the actual difference
Optimisation is describing skills you genuinely have in the language the job uses. Stuffingis gaming the count: repeating words, hiding them, or claiming things you can't back up. The first helps you; the second gets you filtered — modern parsers deduplicate, and recruiters notice padding the moment they read.
The rules that keep it natural
1. One keyword, one home in context
A tool can appear in your Skills section andin one bullet that proves you used it. That's coverage, not stuffing. Listing it five times across the page is the opposite.
2. Put keywords inside achievements
"Built a CI/CD pipeline with GitHub Actions that cut deploy time 60%" carries the keywords andproves them. A skills line that just says "CI/CD, GitHub Actions" is weaker on its own.
3. Match the JD's exact terms for tools
The ATS matches specific technologies literally, so use the form the listing uses — "PostgreSQL" not just "SQL database". For general concepts, natural phrasing is fine; parsers understand common synonyms.
4. Cover the must-haves, skip the noise
You don't need every keyword — focus on the must-haves from the requirements section that you genuinely match.
The honesty boundary
The single rule that keeps optimisation ethical: only add keywords for skills you actually have.A keyword you can't defend in an interview isn't optimisation — it's a liability that surfaces in round one. If the job wants a skill you lack, leave it out or go build a small real project so you can claim it honestly.
Doing it without the manual effort
This is exactly what my-resume automates: it scores your keyword match against a JD, shows present vs missing, and rewrites bullets to include the missing keywords you genuinely have— flagging the ones you don't instead of stuffing them in. Optimisation with the honesty guardrail built in.
