An ATS-friendly resume is a plain, single-column document with standard section headings, selectable text, consistent dates, and the same vocabulary the job posting uses. Applicant tracking systems (ATS) collect applications and turn them into searchable records, so the goal is not to trick software but to make your text easy to extract and easy to find. Clean formatting and honest keyword matching do most of the work.
Key takeaways
- Use a single-column layout, standard headings, and plain text that can be selected and copied.
- Match the posting's exact terms for tools, titles, and certifications, then prove them with evidence.
- Keep dates, job titles, and employers on their own clean lines and in one format.
- Avoid images, text boxes, and body content placed in columns or tables.
- Test the file by copying it into plain text and checking that the order still makes sense.
What does an applicant tracking system actually do?
An ATS does three things: it stores your application, it extracts text from your resume into fields such as name, employer, title, and dates, and it lets recruiters search and filter the stored applications. Hiring decisions still come from people, but many systems also auto-screen required questions and knock-out criteria, so answer every screening question accurately. The system influences which resumes get seen, because a recruiter may search for a specific skill or job title and read only the results.
That is why two problems matter more than any "score." The first is parsing: did your document come through as readable text with the right sections attached to the right entries? The second is matching: when a recruiter searches for a required term, does your resume contain it? Format for the first and write for the second, and you have covered the practical side of ATS optimization.
AI-assisted screening is spreading. A 2025 Harvard Business Review article on getting hired when AI does the screening (HBR, 2025; subscription) notes that companies increasingly use AI tools for resume screens and AI-conducted interviews. Clean, truthful formatting matters more as a result, not less.
What ATS software is not
It is not a single product, and it is not a gate every applicant must defeat. Different employers use different systems, and many smaller employers review applications by hand. A resume that works for a person and parses cleanly is the safest choice for both.
What file format should you submit?
Submit a PDF when the application accepts it and the file was exported from a word processor with selectable text. Submit a DOCX when the posting asks for Word. Avoid scans, screenshots, and image-heavy exports; if you cannot select the text in the file, a parser probably cannot read it either.
| File type | When to use it | Watch out for |
|---|---|---|
| PDF exported from a word processor | Most online applications | Text boxes and columns inside the source file |
| DOCX | Postings that request Word or offer no PDF option | Layout shifting between computers |
| PDF from a design tool | Only when the text exports as real text | Outlined fonts, layers, and image-based text |
| Scanned or photographed page | Never, unless a human explicitly asks for a scan | No machine-readable text at all |
Which layout rules matter most?
Parsers read a document roughly top to bottom, left to right. A single-column layout keeps that order predictable. Two columns, sidebar blocks, and text boxes can interleave unrelated text, so a job title may end up next to the wrong date. Use standard paragraphs and bullets, and leave enough white space that a human reader can skim. CareerOneStop's Resume Formatting Guide sees the same problem from the reviewer's side: recruiters who read hundreds of resumes a day are frustrated by too many fonts, punctuation errors, and inconsistent spacing.
| Element | ATS-safe choice | Risky choice |
|---|---|---|
| Page layout | One column, top to bottom | Two columns or a sidebar |
| Fonts | Common fonts such as Arial, Calibri, Georgia, or Times New Roman | Decorative fonts and icon fonts |
| Section headings | Plain bold text: Experience, Skills, Education | Headings inside shapes or images |
| Bullets | Standard bullet points | Custom symbols, emoji, or arrows |
| Contact info | Typed at the top of the page | Inside a header, footer, or text box |
| Charts and graphics | Leave them out | Skill bars, logos, and rating stars |
Which section headings should you use?
Use the headings recruiters and parsers expect: Summary, Experience (or Work Experience), Skills, Education, and Certifications. Creative labels such as "My Journey" can leave the parser without a section to attach your jobs to.
| Use | Instead of |
|---|---|
| Experience | My Career Journey |
| Skills | What I Bring to the Table |
| Education | Learning and Growth |
| Certifications | Credentials and Badges |
| Projects | Things I've Built |
Section order matters too. Put the most relevant section near the top so a reader can answer "what does this person do?" from the first third of the page. CareerOneStop's Resume Writing Guide uses this same sequence, working through the top section, work experience, education, and optional sections. If the top section is the weak point, start from these resume summary examples.
How do you match keywords without stuffing?
Read the posting and list every required skill, tool, platform, certification, and repeated phrase. Then check your resume against that list. Where the term is accurate for you, use the employer's exact wording at least once, including both the acronym and the full name if the posting uses both, for example "applicant tracking system (ATS)."
| Posting language | Weak resume wording | Stronger wording (hypothetical) |
|---|---|---|
| "Experience with SQL and Tableau" | "Good with data tools" | "SQL and Tableau (built 12 recurring reports for a 9-person sales team)" |
| "Project management" | "Organized tasks" | "Managed a 6-month project across 3 departments, delivered on schedule" |
| "Customer relationship management" | "Used CRM software" | "Customer relationship management (CRM): maintained 800 accounts in Salesforce" |
| "Stakeholder communication" | "Talked to people" | "Wrote weekly stakeholder updates for a 20-person program team" |
Put the important terms in the summary, the skills section, and one or two bullets where you can prove them. Do not repeat a term in every line. A resume that is only keywords is easy to parse and hard to believe; a resume that proves each claim is easy to read and easier to trust.

How should you format dates, titles, and contact information?
Keep each job entry to four clean pieces: employer, job title, location, and dates. Put the title and employer on one line when possible, with dates right after or aligned on the same line. Use one date format throughout, such as "Mar 2021 – Present" or "03/2021 – Present." Do not abbreviate inconsistently or leave dates out.
At the top, type your name, city and state, phone number, and email as plain text. Put your professional profile or portfolio URL on the same block.
Clean entry (hypothetical): Operations Coordinator, Northline Supply, Columbus, OH | Mar 2021 – Present
Same entry, parseable bullets (hypothetical): "Rebuilt the weekly delivery schedule for 26 routes, cutting late deliveries by 15%." "Trained 4 new coordinators on the dispatch system in the first six months."
What should you avoid on an ATS resume?
- Text inside images, charts, or screenshots.
- Skill bars, percentage ratings, and star graphics.
- Sidebars, text boxes, and multi-column body layouts.
- Headings or contact details placed in the document header or footer.
- Hidden keywords in white text or tiny fonts.
- Scanned PDFs, photos of pages, and files exported with outlined text.
Do not hide keywords
White text, zero-point fonts, and metadata stuffing are easy to detect and easy to interpret as dishonesty. If a term matters to the employer, put it in a normal sentence where it is true and visible.
How can you test whether your resume is ATS-friendly?
You can check the most important failure modes yourself in a few minutes, without paying for a scanner or trusting a score.
- Open the final file and press Ctrl+A or Command+A. If any text cannot be selected, it is image-based or locked in a shape.
- Copy all of the text and paste it into a plain text editor. Read the result top to bottom. If the order is scrambled or lines merge, the layout is too complex.
- Search the pasted text for each required keyword from the posting. If a term is missing, add it where it is accurate.
- Check that every job entry still has its title, employer, and dates after the copy-paste.
- Open the file on a second device or in another viewer to confirm the layout holds.
What should you check on an ATS-friendly resume?
Run this list on the final file before you upload it. Most of it takes seconds to verify.
- The resume is one column with standard headings.
- All text is selectable, and pasting into plain text preserves the order.
- The file is a text-based PDF or DOCX, named with your name.
- Every required skill and tool from the posting appears at least once.
- Keywords are used in real sentences with evidence, not repeated in lists.
- Dates, titles, employers, and locations are present for every role.
- No images, icons, skill bars, text boxes, or hidden text appear anywhere.
- Phone, email, and profile links are correct and clickable.
Formatting gets your resume parsed. The writing is what gets it read.

Parsing behavior varies by system, so the guidance here is general; test your own file as described above. If you spot an error, email us — our editorial policy explains how corrections work. Examples on this page are hypothetical illustrations, not real candidates or market data.
Frequently asked questions
Do applicant tracking systems reject resumes automatically?
Applicant tracking systems are built to collect applications, parse the text into searchable fields, and help recruiters filter and sort. Many also auto-screen required questions and knock-out criteria, so answer every screening question accurately. A resume is more likely to be missed because it is hard to parse, lacks the words the recruiter searches for, or does not match the role. Treat the ATS as a filing and search tool — not a single robot judge, but not something to ignore either.
Should I submit a PDF or a Word file?
Submit a PDF when the application accepts it and the file is generated from a word processor, because the layout will look the same on every device. Submit a Word file when the posting asks for one or the system explicitly says it handles DOCX better. Avoid scanned PDFs, image-only files, and PDFs exported from design tools where the text is not selectable.
How many keywords should an ATS resume have?
Enough to cover every required skill in the posting, usually ten to twenty meaningful terms rather than a fixed number. Use the employer's exact wording for tools, methods, certifications, and job titles where it is accurate. Then prove each important keyword with a bullet that shows how you used that skill, because a list of terms without evidence reads as padding.
What resume layout breaks an ATS?
Multi-column layouts, text boxes, tables that hold body content, graphics, icons, headers and footers that carry important text, and image-based files are the most common problems. Parsers read in a linear order, so when text sits in separate columns or boxes, the extracted content can be scrambled or dropped. A single-column document with plain paragraphs parses more reliably.
Do applicant tracking systems understand synonyms for skills?
Many systems match the terms stored in their database and the words recruiters search for, so exact wording matters more than a thesaurus. Use the posting's term at least once for every important tool, method, or certification, then add your own natural wording elsewhere. If the posting says customer relationship management and you normally say CRM, include both. No system guarantees a match, but exact terms improve your odds.
Can an ATS read a two-page resume?
Length itself is rarely the parsing problem; layout and file type matter more. A two-page resume with clean headings, selectable text, and complete dates parses the same way a one-page resume does. The practical question is whether the second page earns its space for a human reader. Keep one page for entry-level roles and use two pages when your relevant history genuinely needs the room.
