Keywords are what get your CV found, and what decide how high it ranks in the pile. Get them right and the software surfaces you; get them wrong and a perfectly qualified CV can sink to the bottom unseen. But there's a right way and a wrong way to do this, and the wrong way is everywhere. Here's how to match your CV to a job description without turning it into keyword soup.
Why keywords matter more than you'd think
Almost every recruiter filters the pile before they read it. Jobscan's research puts it at around 99.7% of recruiters using filters in their applicant tracking system, which means they're searching for specific terms lifted from the job description. If your CV doesn't contain the language the role is screened for, it can rank low enough that nobody ever opens it. And it isn't only the machine: keywords are exactly what a human skimming your CV in a few seconds is hunting for too. Speak the role's language and you're instantly easier to recognise as a fit.
Find the right keywords
You don't need a tool for this, you need to read the advert properly. The keywords are hiding in plain sight: the job title, the named tools and technologies, the core skills, and the phrases that keep cropping up. If a requirement appears twice, it matters. Pull out those exact terms, then mirror the ones that are genuinely true of you. If the role asks for "stakeholder management" and you've done it, write "stakeholder management", not a clever synonym, because the synonym is invisible to a keyword search.
Write for three readers at once
Here's the bit most advice skips. Your CV usually has to land with three different readers, and they each want something slightly different. The applicant tracking system matches exact terms, so it wants the role's vocabulary. The first-pass recruiter often isn't a specialist in your field, so they need to grasp what you did in plain language. The hiring manager usually is a specialist, so they want enough depth to trust you.
That's the balancing act. Use enough of the role's language to clear the filter and reassure the expert, but not so much dense jargon that a non-specialist recruiter can't tell what you actually achieved. Two small habits do most of the work: spell out an acronym the first time you use it, and pair a technical term with the outcome it produced. "Migrated the data pipeline to dbt, cutting reporting lag from a day to under an hour" works for all three readers at the same time.
Keywords in context, not a keyword list
The wrong way to use keywords is to dump them in a comma-separated block at the foot of the page, or, astonishingly, to hide white keyword text on a white background. Both are obvious. Modern systems flag stuffing, and any human who notices stops trusting the whole document.
The right way is to weave the terms into real achievements. Not "Skills: SQL, forecasting, stakeholder management", but "Built the weekly demand forecast in SQL and presented it to senior stakeholders, improving stock accuracy by 12%". Same keywords, except now they're earning their place. A good rule of thumb: the important terms should appear naturally across the CV, not crammed in. If a sentence exists only to carry a keyword, cut it.
Match honestly
One rule sits above all the others: a keyword should never be a claim you can't stand behind. It's tempting, especially with AI tools, to reverse-engineer a CV from the advert until it matches on every single point, but a keyword you can't defend becomes a trapdoor the moment an interviewer asks you about it. Match on what's genuinely true, and where there's a real gap, reach for transferable experience rather than inventing the term. (Building a first CV with little to draw on? Our no-experience guide shows what counts.) A CV that's 90% matched and entirely true beats one that's 100% matched and part fiction. (We cover why the over-tailored CV falls apart in the room in its own guide.)
A simple method
- Read the advert and list its repeated terms: the title, the tools, the core skills.
- Mark the ones that are genuinely true of you.
- Work those into your achievements, each with evidence or a number.
- Spell out acronyms once, and pair any jargon with the result it produced.
- Read it back as a non-expert: can they still tell what you did?
Done well, keyword matching isn't gaming the system. It's just making it easy for the software and the people behind it to see what you already are: a strong fit. Before you send anything, it's worth checking the CV still reads cleanly to the machine, which is where our guide to passing an ATS scan comes in.
