75% of resumes are rejected by ATS software before a human ever reads them. Not because the candidates are unqualified — because their resumes aren't formatted for machines. ATS (Applicant Tracking System) software parses your resume as plain text, scores it against the job posting, and decides whether a recruiter sees it. If your resume confuses the parser or misses key terms, you're filtered out automatically.
This guide covers everything you need to pass ATS screening: formatting rules, keyword strategy, file format, and common mistakes that get qualified candidates auto-rejected.

CHECK MY RESUME →An Applicant Tracking System is software that companies use to manage job applications. When you submit your resume online, it goes into the ATS, which parses the document, extracts information, and scores it against the job posting. Recruiters then see a ranked list of candidates — those with the highest scores get reviewed first.
Over 97% of Fortune 500 companies and roughly 75% of all employers use some form of ATS. The most common platforms are Workday, Greenhouse, Lever, iCIMS, Taleo, and BambooHR. Each handles parsing slightly differently, but the principles for passing them are the same.
Two-column resumes look professional to humans but break ATS parsing. The software reads left-to-right across the full page width, not column by column. Your sidebar information gets mixed into the wrong sections. A single column with content flowing top to bottom is the only reliable layout.
The ATS needs to categorize your information. It recognizes "Professional Experience" but not "Career Highlights." Use these standard headers: Professional Summary, Professional Experience (or Work Experience), Education, Skills, and Certifications. Creative headers cause your content to end up uncategorized.
This is the single most important factor. Read the job posting and identify every skill, tool, certification, and industry term. Then use those exact phrases in your resume. If the posting says "stakeholder management," write "stakeholder management" — not "managed relationships with stakeholders." ATS often uses exact string matching.
Write "Search Engine Optimization (SEO)" at least once. Some ATS systems scan for the full phrase, others for the acronym. Including both covers every platform. This applies to PMP/Project Management Professional, CRM/Customer Relationship Management, and any industry abbreviation.
Word documents (.docx) are the most universally compatible format across all ATS platforms. PDFs work with most modern systems but can cause issues with older platforms, especially image-based PDFs. Unless the application specifically requests PDF, go with .docx.
Tables, text boxes, embedded images, icons, skill bars, and charts are either invisible to the ATS or parsed incorrectly. Any information conveyed only through visual elements will be lost. Stick to plain text, standard bullet points, and simple formatting.
Every bullet point under your work experience should include a measurable result. "Increased quarterly sales by 35% through strategic account management" is better than "Responsible for managing sales accounts." Numbers satisfy both the ATS (keywords like "sales," "account management") and the recruiter (the 35% result).
Sending the same resume to every job. Each posting has different keyword requirements. A resume tailored for one role may score poorly against a different posting in the same field. Customize your keywords for each application.
Putting contact info in the header/footer. Many ATS systems skip document headers and footers entirely. Place your name, phone, email, and location in the main body of the document.
Using a resume template from Canva or similar tools. Many design-focused templates use multi-column layouts, text boxes, and graphics that break ATS parsing. Start with a plain Word document instead.
Not checking your score before submitting. You wouldn't submit a report without proofreading. Don't submit a resume without checking its ATS compatibility. A free tool like Resume Weapon shows your score and missing keywords in seconds.
The quickest way is to use a free ATS checker. Resume Weapon (atsresumechecker.io) lets you upload your resume, optionally paste the job posting you're targeting, and get an instant score from 0-100. It shows which keywords match, which are missing, and what formatting issues exist. The tool also includes an AI resume builder that can generate an ATS-optimized version automatically.
A simple DIY test: copy your resume content and paste it into a plain text editor (Notepad, TextEdit). If the text appears garbled, out of order, or missing sections, the ATS is probably seeing the same problems. Everything should paste in the correct order with all content intact.
