Rewrite Your Resume for Applicant Tracking Systems: A Field Guide

Why Your Resume Is Being Rejected Before a Human Reads It

You’ve sent out dozens of applications and heard nothing. The problem might not be your experience—it’s likely your resume never made it past the software. Applicant tracking systems (ATS) are used by 98% of Fortune 500 companies, and they screen for specific keywords, formatting, and structure. According to a 2023 study by Jobscan, 75% of resumes are rejected by an ATS before a recruiter ever sees them.

ATS software parses your resume into a database, extracting your contact info, work history, education, and skills. If the system can’t read your file, or if it doesn’t find the right keywords, your application is quietly discarded. The good news: you can write a resume that satisfies both the bots and the humans.

Use a Standard, Single-Column Layout

ATS systems are easily confused by creative formatting. Tables, text boxes, columns, graphics, and unusual fonts can cause the parser to jumble your information. To ensure your resume is parsed correctly, use a simple, single-column layout with standard headings like “Work Experience,” “Education,” and “Skills.”

Use a common font such as Arial, Calibri, or Times New Roman, in 10–12 point size. Save your file as a .docx file, which is the most compatible format for ATS. PDFs can be read by many systems, but they sometimes cause parsing errors, especially if the PDF was created from a scanned image. When in doubt, .docx is safest.

Match Keywords from the Job Description

ATS software scans for specific keywords that match the job posting. If the job description mentions “project management,” “budgeting,” and “Stakeholder communication,” your resume should include those exact phrases—if you genuinely have that experience. Don’t just copy the entire job description; instead, incorporate relevant keywords naturally into your bullet points.

For example, if you’re applying for a marketing role, and the job description lists “SEO” and “content strategy,” make sure those terms appear in your resume. Use the same phrasing as the job description. If they say “budget management,” don’t write “handled finances.” The ATS might not recognize the synonym.

Use a Reverse-Chronological Format

Recruiters and ATS systems prefer a reverse-chronological format, listing your most recent job first. This format is easy to parse and clearly shows your career progression. Functional resumes—those that emphasize skills over job titles—are often rejected by ATS because they lack a clear work history.

For each job, include your job title, company name, dates of employment, and 3–5 bullet points describing your achievements. Use strong action verbs like “led,” “increased,” “developed,” and “implemented.” Quantify your achievements whenever possible. For instance, “Increased sales by 20% in six months” is more powerful than “Responsible for sales growth.”

Tailor Your Resume for Each Application

One size does not fit all. ATS systems rank resumes based on how closely they match the job description. To get a high match score, you must tailor your resume for each application. This doesn’t mean rewriting your entire resume; it means adjusting your summary, skills section, and some bullet points to align with the specific job.

Start by identifying the top 10–15 keywords from the job description. Then, incorporate those keywords into your resume, especially in your professional summary and skills section. A professional summary at the top of your resume is a great place to include a few key phrases. For example, “Results-driven project manager with 5 years of experience in Agile methodologies and cross-functional team leadership.”

Step-by-Step: How to Optimize Your Resume for ATS

Follow these steps to create an ATS-friendly resume that gets you in front of a human recruiter.

1. Analyze the job description: Copy the job posting and paste it into a word cloud tool or simply highlight the most repeated terms. These are your keywords.
2. Create a master resume: List all your skills, experiences, and achievements. This is your raw material.
3. Build a tailored resume: For each application, copy your master resume and edit the summary, skills, and bullet points to match the job description.
4. Use standard headings: Label sections clearly: “Professional Summary,” “Work Experience,” “Education,” “Skills.” Avoid creative headings like “Career Highlights” or “What I Bring to the Table.”
5. Save as .docx and name your file clearly: Use a file name like “YourName_Resume.docx” rather than “Resume_Final_v3.docx.”
6. Test your resume with an ATS checker: Tools like Jobscan or Resume Worded can analyze your resume against a job description and give you a match score. Use them to refine your resume.

Write Bullet Points That Get Noticed

Your bullet points should be concise, achievement-oriented, and keyword-rich. Start each bullet with an action verb, and include a number or a specific result when possible. For example:

• “Managed a team of 12 and reduced project turnaround time by 30%.”
• “Negotiated vendor contracts, saving the company $50,000 annually.”
• “Launched a customer loyalty program that increased repeat purchases by 25%.”

Avoid vague phrases like “responsible for” or “helped with.” Instead, use strong verbs and focus on outcomes. The ATS will pick up on these verbs, and human recruiters will be more impressed.

Common ATS Mistakes to Avoid

Even with the right keywords, you can trip up the ATS with simple errors. Avoid these common mistakes:

• Using headers or footers for your contact information—ATS may not read them.
• Including images, logos, or icons—they are not parsed.
• Using tables or multiple columns—they cause parsing errors.
• Submitting a resume in a non-standard format like .pages or .odt.
• Using a functional resume format—it’s often rejected.

Instead, put your name, phone number, and email in the body of the document, not in a header. Use a simple layout with clear section headings.

The Role of Cover Letters in an ATS World

Cover letters are often ignored by ATS, but they still matter to human recruiters. Many ATS systems allow you to submit a cover letter, but they don’t parse it. However, a well-written cover letter can be the difference when a recruiter is deciding between two equally qualified candidates. Use your cover letter to highlight a specific achievement or explain something unusual in your work history.

Keep your cover letter to one page, address it to a specific person if possible, and mention the job title and company. Avoid generic greetings like “To Whom It May Concern.” Instead, try to find the name of the hiring manager on LinkedIn or the company website.

Conclusion

Your resume is your first impression, and in the digital age, it’s often read by a machine before a human. By using a standard format, matching keywords, and tailoring your resume for each application, you can get past the ATS and into the hands of a recruiter. Remember to quantify your achievements, use action verbs, and proofread for errors. The extra effort will pay off in more interviews.
