You apply for a role that fits your profile perfectly, you wait for a reply, and the answer is silence. In around 75% of cases, your CV never reached a human recruiter at all : it was filtered out by an ATS (Applicant Tracking System), a piece of software that scans your application looking for specific ATS keywords. Without those terms, your CV doesn't make it past the door.
The good news: recruiters themselves configure the ATS with a finite list of words, and almost all of them are visible in the job advert. Spotting them, weaving them naturally into your CV, and structuring your document so the parser reads them correctly is what separates a CV that sits in a database from a CV that lands an interview. Here are the 12 keywords that come up most often, how to find them, and the mistakes to avoid.
How an ATS actually reads your CV
The ATS is not a clever AI that understands your career. It's a parser: it slices your CV into sections (experience, education, skills) and looks for the terms the recruiter has loaded in the brief. Every match raises your matching score. If you pass the defined threshold (often 60 or 70%), your CV moves up into the pile a human will see. If you don't, it stays in the database, indexed but invisible.
Three practical consequences:
- The same keyword counts more than once. If it appears in your summary, your experience block and your skills, it carries more weight.
- The exact form of the word matters. "Project management" and "project manager" are two different tokens for most ATS systems. You often need both.
- Context boosts the score. A keyword on its own counts less than the same keyword paired with an action verb, a metric or a tool.
According to the ONS Vacancy Survey, the UK posts more than 800,000 vacancies in any given month. With volumes that high, the National Careers Service confirms that mid-to-large employers now lean on ATS software as a first filter before any human review. Job seekers therefore need to write a CV that talks to the parser first, the recruiter second.
A 3-step method to find the right keywords
Before looking at the universal list of 12, your single best source is always the advert itself. A simple workflow that works:
- Copy the job title + the "responsibilities" block + the "requirements" block into a plain text editor. That accounts for around 70% of the useful material.
- Highlight every noun, every acronym and every tool mentioned. You will end up with 15 to 25 terms. These are your candidate keywords.
- Cross-check against 3 to 5 similar adverts from competitors. Words that appear in the majority of ads are the ones ATS systems in your sector prioritise.
At this point you have a personalised list. The next section gives you the 12 keywords that go beyond any individual role: they are so transversal that any ATS, in any sector, weighs them heavily.

The 12 ATS keywords that land resume interviews
1. Led (and its variants: managed, directed, oversaw)
The verb "led" is one of the most-scanned ATS keywords for any role with responsibility : even at junior level. It signals an active stance. Example: "Led a 6-month cloud migration project" carries more weight than "Participated in a cloud migration project." Use it whenever you genuinely coordinated work, however small the scope.
2. Optimised / Improved
A universal keyword that ATS filters look for in nearly every sector. It implies a measure: optimised what, by how much, in what time. Example: "Improved order processing time by 35%." Avoid "optimised processes" without a number : the ATS does not penalise it, but the human recruiter who eventually reads your CV will.
3. Project management
A top-3 skill scanned by ATS across all sectors, confirmed by the Department for Education's Employer Skills Survey. State the methodology (Agile, Scrum, Kanban, Waterfall) if you've actually used it. If you hold a PMP, PRINCE2 or Scrum Master certification, cite it in the same sentence to stack the matches.
4. KPI (and performance metrics)
"KPI" is one of those ATS keywords that lifts a junior CV because it shows you speak the language of business. Paired with a number it becomes lethal: "Defined and monitored 5 monthly commercial KPIs." Acceptable variants: "performance indicators", "OKRs", "targets".
5. Fluent English / B2 / C1
ATS systems always look for a formal language level. Never write "good level of English": the term does not exist in any reference framework. Use CEFR (B1, B2, C1, C2) or IELTS/TOEFL with a score. For international roles, "fluent in English" plus your native language in the skills section doubles the chance of matching English-language filters.
6. Excel (and Microsoft Office)
Banal but devastatingly effective. Excel is still the most-scanned ATS keyword for administrative, financial, commercial and marketing roles. Specify the level ("Advanced Excel: pivot tables, VLOOKUP, macros") rather than "Microsoft Office proficient". If you use Google Workspace, add "Google Sheets" and "Google Workspace" separately : they are different tokens.
7. Reporting
Found in 8 out of 10 adverts on UK platforms such as Reed and Prospects. "Reporting" signals you can package data for decision-makers. State the cadence and audience: "Weekly reporting to the executive committee on commercial performance".
8. Budget managed
A bottom-of-funnel keyword for the ATS: it filters out profiles without real ownership. Quantify it: "Annual budget owned: £250k". If you haven't owned a budget yourself, use "contribution to budget planning" : that phrasing is accepted by most parsers without overstating your role.
9. Team managed (with a number)
The ATS filter wants a number after "team". "Managed a team of 4 interns" beats "team management" with no detail. If you haven't managed anyone, drop the word and switch to "cross-functional collaboration with X departments", which also matches filters without misrepresenting your experience.
10. B2B / B2C
Acronyms that get scanned aggressively for commercial, marketing and SaaS profiles. If your market is B2B, write it 2 to 3 times across the CV (summary + experience + skills). UK filters increasingly also look for "enterprise", "SME", "mid-market" : name the actual segment you sold to.
11. Certified [PMP / Google / AWS / HubSpot / Scrum…]
Certifications are high-coefficient ATS keywords because they are rare and easy to parse. Spell out the exact certification (consult the UK Register of Regulated Qualifications for recognised credentials) with the year and the awarding body. One well-placed certification can lift your CV ranking by 20 to 30%.
12. Master's / MSc / MBA
The ATS expects a standardised qualification level. Always spell out the level alongside the title ("MSc in Marketing : University of Manchester"). For European recruiters add the local equivalent ("Master 2 / Diplom-Kaufmann"). European ATS systems frequently look for both formats in parallel.

3 fatal mistakes to avoid with keywords
Mistake 1 : Keyword stuffing. Stuffing your CV with keywords and no context, sometimes in white text on white background to fool the ATS. That trick worked five years ago; not now. Modern parsers flag density anomalies and the human recruiter (who always ends up reading the CV) penalises it instantly. The healthy rule: one keyword every 50 to 100 words, never twice in the same sentence.
Mistake 2 : Copy-pasting from the advert. Lifting entire sentences from the job description. Beyond the plagiarism risk, several AI-enhanced ATS now flag CVs that are too close to the source text. Rephrase, keep only the nouns and acronyms : that's all that counts for scoring.
Mistake 3 : Putting keywords in a "Skills" block only. Many candidates create a "Key Skills" block and dump 30 terms into it. Problem: ATS systems weight keywords found in the "Experience" block more heavily than items in an isolated list. Spread your keywords across the whole CV: job titles, experience bullets, education, certifications.
Free tools to identify your target keywords
Three tools you can use without signing up:
- Online word clouds: paste 5 similar adverts into wordart.com or wordclouds.com to surface the most frequent terms visually.
- Jobscan free tier: compares your CV to an advert and lists missing keywords. The free version offers 5 scans per month.
- The GOV.UK Find a Job portal: each advert exposes an explicit "Skills required" block that has already been extracted by DWP teams. A great signal of what really matters in the UK market.
For tech profiles, the Stack Overflow Developer Survey and the annual HackerRank Developer Skills Report publish the most-requested skills by stack.
The golden rule: adapt without lying
A CV tailored to a job advert always outperforms a generic CV : but tailoring has a limit: never add a keyword for a skill you don't have. The ATS filters at the door, but the interview resets the scoreboard. A recruiter who discovers on a video call that you don't know Salesforce, even though it sits in bold on your CV, will not call you back. Adapt 80% of your vocabulary, keep 20% off-script to stay genuine.
