The ATS Checklist: What Applicant Tracking Systems Actually Read

Your resume might be well written and still never reach a human because of a text box, a table, or a header the software cannot read. That is not a hiring decision — it is a software failure, and you can fix it in an afternoon.

Why formatting breaks before a human ever sees it

An applicant tracking system, or ATS, is software that scans your resume into a database before anyone reads it. It pulls out your name, contact details, job titles, dates, and skills and drops them into fields. If the software misreads the layout, your information lands in the wrong field or disappears entirely — and the recruiter sees a blank space where your last job title should be. This is not about keywords alone. It is about whether the parser can find the words at all. A visually appealing resume with columns and icons can genuinely score worse than a plain one, because the software reads left to right, top to bottom, in a straight line, and anything that breaks that line confuses it.

The layout rules that actually parse

Use a single column from top to bottom. Two columns might look modern, but many systems read across both columns as if they were one line, scrambling your dates and job titles into nonsense. Stick to one of a small handful of standard fonts — Calibri, Arial, Georgia, or Times New Roman — at 10 to 12 point size, because unusual fonts sometimes fail to embed correctly and show up as symbols. Use plain bullet points, the simple round or square kind, not arrows, checkmarks, or custom icons. Left-align everything. Avoid centering your name and contact information at the top in a decorative block; simple left-aligned text just below the top margin is safest. Keep your margins between 0.5 and 1 inch so nothing gets cut off when the software converts your file to plain text internally.

Section headings, job titles, and dates the system expects

ATS software looks for familiar words to sort your information, so use the standard labels: Work Experience (or Experience), Education, Skills, and Certifications. Do not get creative with headings like "My Journey" or "What I Bring" — the software has no idea what to do with those, and neither will a recruiter skimming fast. Under each job, list your job title, the employer name, and the dates you worked there, in that order, on their own line or close together. Use a consistent date format throughout, such as "03/2021 to 06/2023" or "March 2021 to June 2023" — pick one style and use it everywhere, because mixed formats can cause the parser to skip a field it does not recognize. If you are currently employed, write "to Present," not a blank space, since a blank can register as missing data. Spell out your job title exactly as the industry would search for it — if you did the work of a "Customer Service Representative" but your official title was something obscure, consider listing the common title first and the official one in parentheses, so both the software and the human reader recognize it.

Here is a line you can copy exactly and adapt with your own details:

Warehouse Associate, Midstate Logistics — 04/2022 to Present

That single line format — title, comma, employer, dash, dates — is the safest pattern for both software and human eyes, and it works in nearly every industry.

File formats: what to save and what to avoid

Save your resume as a .docx file unless the job posting specifically asks for a PDF. Most modern systems read PDFs fine, but some older or poorly configured ones still struggle with PDFs created from design software, so .docx remains the safer default when you are not told otherwise. Never submit a resume as a .pages file, a scanned image, or a photo of a printed page — none of these can be read as text at all, and the system will log an empty profile. If a posting gives you a choice, use the exact file type it requests, and name your file clearly, like "FirstName-LastName-Resume.docx," so a human skimming a folder of a hundred files can find and recognize yours immediately.

What to remove completely

Remove tables used for layout, even invisible ones with no visible borders, because many systems read table cells out of order or skip them altogether. Remove multi-column sections, including the common two-column "skills on the left, experience on the right" design — it looks organized to a human but reads as scrambled text to software. Remove text boxes entirely; anything placed in a text box is frequently invisible to a parser, meaning your carefully written summary at the top of the page may simply not exist to the system. Remove graphics, icons, logos, charts, and headshot photos — they add nothing the software can use and sometimes cause the whole document to fail parsing. Most importantly, never put your name, phone number, or email address inside a page header or footer. Headers and footers are often skipped entirely by ATS software, meaning the system literally cannot find a way to contact you even though your resume looks complete when a human opens it directly. Put your contact details in the main body, left-aligned, at the very top of the first page.

Why a human still reads what reaches them

Passing the ATS only earns you a chance — a person still opens the file, usually a recruiter or hiring manager, and they decide in under a minute whether to keep reading. This is why formatting for the software and writing for a human are not separate jobs; they are the same resume, built to survive two filters in a row. Once your resume is parsed correctly, a human reader is looking for clear job titles they recognize, numbers that show results, and no obvious gaps without explanation. Keep writing the same resume you always would — with real accomplishments, approximate numbers where you can honestly estimate them, and plain language — just stripped of the visual tricks that confuse software. A resume that is both ATS-readable and genuinely well written is not a compromise; it is simply a resume with no unnecessary risk built into it.

Here is a checklist you can work through this week, one item at a time:

1. Open your current resume and check for any tables, text boxes, or multi-column sections, and remove them.
2. Move your name, phone number, and email out of the header or footer and into the main body at the top.
3. Rename your section headings to Work Experience, Education, and Skills if they are currently anything unusual.
4. Check every job entry for a consistent format of title, employer, and dates, matching the pattern shown above.
5. Save a clean copy as a .docx file and a separate copy as a .pdf, so you have both ready depending on what a posting requests.
6. Read the document aloud top to bottom in a straight line, the way software would, and fix anything that only makes sense visually rather than in plain text order.

If you only do three things

1. Strip out every table, column, text box, and graphic, and put your contact details in the body of the page, not the header.
2. Use standard section headings and a consistent title-employer-dates format for every job you list.
3. Save your file as a .docx unless a posting specifically asks for something else, and name the file clearly with your name on it.
