An ATS-friendly resume is a resume laid out so that an applicant tracking system can pull out your details correctly and a recruiter can find you when they search. The rules are simpler than most "beat the bots" advice suggests: a clean single-column layout, standard section headings, a common file type, and wording that matches the job advert where it honestly fits.
This guide explains what an ATS is, what vendors themselves say breaks resume parsing, how to format and word your resume, and how to check it before you apply. (In the UK and much of the world the document is usually called a CV. Everything here applies to both.)
What is an ATS?
An ATS (applicant tracking system) is software that employers use to receive applications, store candidate details, move people through hiring stages and search their candidate database. When you apply through a company's careers page, your resume usually goes into its ATS.
Most systems "parse" your resume: they read the document and copy details such as your contact information, job history and education into structured fields. Recruiters then review applications, filter on the screening questions the employer set, and search the database by keywords, job titles or skills.
Two things follow from that:
- If the parser can't read your resume, your details may be missing or jumbled when a recruiter looks at your profile.
- If your resume doesn't use the words a recruiter searches for, you may not show up in a search, even if you're well qualified.
Some employers also use AI tools to help screen applications. In Ontario, Canada, employers with 25 or more employees must now say in a publicly advertised job posting if they use AI to screen, assess or select applicants (for postings from 1 January 2026), according to the Ontario government.
How does ATS resume parsing work?
The parser reads the text in your file and tries to work out which parts are your name, phone number, employers, job titles, dates and so on. It works best when the document has a predictable structure.
Vendors document what trips their parsers up. Greenhouse, a widely used ATS, lists these causes of failed or partial parses in its resume parsing help article:
| What Greenhouse says can cause problems | What to do instead |
|---|---|
| Resume uploaded as an image | Upload a .docx or a PDF exported from a word processor, so the text is selectable |
| Files over its 2.5MB limit (usually from images) | Remove photos and graphics; keep the file small |
| Graphics, photos and word art | Use plain text |
| Tables, text boxes and columns | Use one column with simple line breaks |
| Headers and footers | Put your name and contact details in the main body |
| Letter-spacing and unclear sections | Use normal spacing and clear headings |
| Company names without identifiers like "Inc." or "LLC", and incomplete job titles | Write the full company name and full job title |
| Placeholder or fake data | Use real details only |
Greenhouse also notes that when parsing fails, the resume is still attached to the candidate profile and details have to be entered manually, and that partial parses need checking. Other systems work differently, so treat this as a guide to what commonly goes wrong.

What is the best ATS resume format?
A reverse-chronological resume in a single column is the safest choice for most people. Here's a layout that parses well and reads well to humans.
ATS-friendly resume template (example):
Firstname Lastname City, Country | phone | email | LinkedIn URL Summary Two or three lines: your role, your strongest skills, and the kind of job you want. Experience Job Title, Company Name Ltd, City | Month Year to Month Year - Achievement with a result - Achievement with a result Skills Skill, skill, tool, tool, language Education Degree, Institution | Year Projects / Certifications Project or certificate, with one line on what you did
Formatting rules:
- File type: .docx or a text-based PDF. Follow the employer's instructions if they state one.
- Headings: standard words such as Summary, Experience, Skills, Education. Creative headings ("My Journey") make sections harder to identify.
- Fonts: a common font at a readable size. Avoid symbols and icons in place of words (a phone icon instead of "phone").
- Dates: a consistent format, such as "Mar 2022 to Jun 2025", on every role.
- Bullets: simple round bullets. Avoid unusual symbols.
- Length: as long as it needs to be to show relevant experience, and no longer. One to two pages suits most people.
- Design: save the two-column, colour-heavy version for networking or for handing over in person.
How do you get the keywords right?
Use the words the employer uses, for skills and experience you genuinely have. That's all "ATS keywords" means.
- Copy the job advert into a document. Highlight job titles, hard skills, tools, qualifications and repeated phrases.
- Match the exact terms. If the advert says "stakeholder management" and you wrote "working with partners", use their phrase. If it says "Salesforce", write "Salesforce", not "CRM software".
- Include both forms of abbreviations the first time: "search engine optimisation (SEO)".
- Put keywords where they carry meaning. In your summary, your skills section and, most importantly, in bullet points that show you using the skill.
- Don't stuff. Repeating a word 20 times or hiding keywords in white text doesn't help when a person reads the resume, and recruiters do read them.
Before and after (example):
Before: Responsible for helping customers with problems. After: Resolved customer issues by phone, email and live chat in Zendesk, and wrote 12 help-centre articles that cut repeat questions on billing.
The "after" version uses tool names and task words a recruiter might search for, and shows a result. If a number isn't something you can stand behind, describe the outcome in words.
Do resume checkers work?
A resume checker can catch formatting problems and show which words from a job advert are missing. It can't tell you how a particular employer's ATS will read your file, or how a recruiter will judge you.
Use one as a second opinion, then apply common sense:
- Do act on: unreadable sections, missing contact details, missing skills you really have.
- Be sceptical of: a single "ATS score". There is no standard score that all employers use.
- Never: add skills you don't have to raise a match percentage. It will come out in interview.
A free check you can do yourself:
- Open your PDF, select all the text and paste it into a plain text editor. Is everything there, in the right order?
- Save your resume as plain text (.txt) from your word processor. Do headings, dates and job titles still make sense?
- Read the plain version next to the job advert. Are the key skills from the advert visible?
If any of those look scrambled, simplify the layout.
What should an ATS resume include if you've been laid off or changed careers?
The same structure, with a few extra steps:
- Recent layoff: list your end date honestly. A recent layoff isn't a red flag. See how to explain being laid off in an interview.
- Gap in employment: a one-line note in the experience section can help ("Career break: caring responsibilities, 2024 to 2025"). See how to handle an employment gap.
- Career change: lead with a summary that names the new target role, and add a projects section with relevant work. See how to change careers.
- No direct experience: use projects, volunteering and job simulations as evidence. See how to get a job with no experience.
Why is my ATS-friendly resume still not getting interviews?
Formatting gets you read correctly. It doesn't make you the strongest candidate. If a clean, tailored resume still isn't getting responses, the cause is usually one of these:
| Symptom | Likely cause | What to try |
|---|---|---|
| No replies at all | Applying to roles that are a stretch, or applying late | Narrow your targets; apply soon after a role is posted |
| Replies only for junior roles | Achievements don't show your level | Rewrite bullets around scope and results |
| Interviews but no offers | The resume works; interviews need practice | Practise the real tasks of the job |
| Silence after many applications | Some listings may not be real openings | See ghost jobs |

A resume is a claim about what you can do. Many employers now want evidence as well, and some ask candidates to complete work tasks before interviews. You can practise on a Cohesyve job simulation for your target role, get a scored report, and add a skills profile link to your resume.
FAQs
Is a PDF or Word resume better for an ATS?
Either usually works if the text is real text (not an image) and the layout is simple. Greenhouse's documentation describes a resume as a document "such as a .docx or .pdf". Follow the employer's instructions if they give any.
Can an ATS read a two-column resume?
It may not read it correctly. Greenhouse lists columns, tables and text boxes among the things that can prevent parsing. A single column is the safe option.
Does an ATS automatically reject resumes?
It depends on how the employer sets it up. Employers can add screening questions (for example, about right to work or a required licence), and recruiters filter and search applications. Answer screening questions accurately and make sure your resume clearly shows the requirements you meet.
Should I put my contact details in the header?
Put them in the main body at the top. Greenhouse lists headers and footers as a cause of parsing problems.
How many keywords should an ATS resume have?
There's no set number. Include the skills, tools and titles from the advert that truthfully describe you, used naturally in context.
