ATS Resume Tips: How to Beat the Bots and Get More Interviews

What Is an ATS and Why Does It Matter for Your Resume?

An Applicant Tracking System (ATS) is software that automatically scans, parses, and ranks resumes before a human recruiter ever sees them: and over 98% of Fortune 500 companies use one. If your resume is not formatted correctly or lacks the right keywords, it gets filtered out automatically regardless of your qualifications. Understanding how ATS works is the first step to getting past it.

What Resume Format Works Best for ATS?

A single-column, chronological resume in a standard font (such as Arial, Calibri, or Times New Roman) at 10–12pt size is the most ATS-compatible format. Avoid tables, text boxes, headers/footers for important content, graphics, and columns: ATS parsers read left to right and top to bottom, and complex layouts cause parsing errors that bury your information.

How Do You Find the Right Keywords for Your Resume?

Copy the job description into a word frequency tool or read it carefully for repeated nouns and skill phrases: those are the exact keywords the ATS is programmed to find. A job posting that mentions "project management" four times expects to see that phrase in your resume. Mirror the language from the job description precisely; "managed projects" is not the same as "project management" to an ATS parser.

Where Should Keywords Appear on an ATS-Friendly Resume?

Place target keywords in your professional summary, skills section, and within the bullet points of each relevant role: repeating each key term two to three times signals relevance without looking like keyword stuffing. The skills section is particularly important because many ATS systems extract it separately and score it against the job requirements. Use both the spelled-out version and abbreviation (e.g., "Search Engine Optimization (SEO)") to cover both formats.

Should You Use a PDF or Word Document When Applying Through an ATS?

Submit a .docx (Word) file when applying through an ATS portal unless the job posting specifically requests PDF: Word documents parse more reliably across most ATS platforms. Some older ATS systems cannot read PDFs correctly and will parse the content as a string of random characters. When in doubt, check the job posting instructions or submit both formats if the system allows it.

What Are the Most Common ATS Resume Mistakes?

The five most common ATS-killing mistakes are: using images or graphics, putting contact information in headers, using creative section titles, submitting a resume as an image file, and writing skills in a visual rating format (e.g., progress bars). Section headers must match standard labels like "Work Experience," "Education," and "Skills": not "My Journey," "Where I've Been," or "What I Know."

How Long Should an ATS-Optimized Resume Be?

One page for candidates with under ten years of experience; two pages for senior professionals: ATS systems do not penalize length, but human recruiters who receive your resume after ATS filtering prefer concise documents. Every bullet point should start with a strong action verb and contain a quantifiable result where possible (e.g., "Reduced customer churn by 23% by implementing proactive outreach sequences").

What Is a Good ATS Score for a Resume?

An ATS match score of 75% or higher against a specific job description gives you a strong chance of passing the automated filter and reaching a recruiter. Scores below 60% suggest your resume is missing critical keywords or skills the employer prioritizes. Use our free ATS resume scorer to check your score against any job description in real time.
