10 ATS Resume Tips That Actually Work
Published · 6 min read
Most large employers run applications through an applicant tracking system, and plenty of mid-size ones do too. You will see very precise percentages quoted for this, and they trace back to companies selling ATS optimization rather than to independent research, so treat the exact figure as unknown and the general fact as true. If your resume is not optimized for ATS parsing, it does not matter how qualified you are. Your application may never reach a recruiter. The good news is that ATS optimization is not about gaming the system. It is about presenting your qualifications clearly and in a format that both machines and humans can easily read.
1. Use a Clean, Single-Column Layout
Multi-column layouts, tables, and text boxes may look elegant to the human eye, but most ATS software reads documents linearly from top to bottom, left to right. When content is spread across columns or embedded in tables, the system often scrambles the order, merging unrelated sections or skipping content entirely. Stick with a single-column layout and use clear spacing between sections instead of visual dividers.
2. Mirror Keywords from the Job Description
ATS software ranks candidates partly by how closely their resume matches the language of the job posting. If the posting says "project management" and your resume says "managing projects," the system may not recognize the match. Read the job description carefully, identify the most important skills, tools, and qualifications, and use those exact phrases in your resume. This is not keyword stuffing. It is speaking the same language as your potential employer.
Tip: Copy the job description into a word cloud generator to see which terms appear most frequently. Those high-frequency terms are likely the keywords the ATS is scoring against.
3. Use Standard Section Headings
Creative section titles like "Where I Have Made an Impact" or "My Toolkit" confuse ATS parsers. Use universally recognized headings: "Work Experience" or "Professional Experience," "Education," "Skills," "Certifications," and "Summary" or "Professional Summary." These labels map directly to the fields the ATS expects to populate in its database.
4. Include Both Acronyms and Full Terms
Different job postings use different versions of the same term. One may say "Search Engine Optimization" while another says "SEO." Include both versions at least once in your resume to cover all bases. For example: "Led Search Engine Optimization (SEO) strategy that increased organic traffic by 150%."
5. Avoid Images, Charts, and Graphics
ATS software cannot read images. That means your carefully designed skill-level progress bars, headshot photo, or infographic timeline is invisible to the system. Any information conveyed solely through graphics will be lost. Use plain text for all content, and save creative design elements for your portfolio website.
Tip: If you want a visually appealing resume for networking or in-person events, maintain two versions: an ATS-optimized version for online applications and a designed version for direct sharing.
6. Save as PDF (Unless Told Otherwise)
PDF files preserve formatting across devices and are parsed well by modern ATS platforms like Greenhouse, Lever, and Workday. However, some older systems (particularly in government and large enterprise) still prefer .docx files. Always check the application instructions. If no format is specified, PDF is the safer choice in 2026.
7. Put Your Contact Information in the Body, Not the Header
Many ATS platforms skip content placed in document headers and footers. Put your name, email, phone number, LinkedIn URL, and city/state at the very top of the document body. There is no need to include your full street address. City and state are sufficient for most applications.
8. Use Standard Date Formats
ATS software parses dates to calculate your years of experience. Use a consistent format like "Jan 2023 to Present" or "January 2023 to March 2026." Avoid ambiguous formats like "2023-2026" (which could mean January to December or any months in between) and never use seasons ("Summer 2023").
9. Do Not Stuff Keywords Invisibly
Some candidates try to hide keywords in white text or microscopic font sizes. Modern ATS platforms detect this tactic, and it can result in your application being flagged or automatically rejected. Even if the system does not catch it, a recruiter who copies your resume text will see the hidden content. It is a career-ending move if discovered.
Tip: The best keyword strategy is the most honest one: only include skills and tools you can genuinely discuss in an interview. Fabricated keywords may get you past the ATS but will backfire during screening calls.
10. Test Your Resume Before Submitting
Before you apply, test how your resume parses. Copy the text from your PDF and paste it into a plain-text editor. Does it read in the correct order? Are all sections intact? Is the formatting preserved? You can also use free ATS-simulation tools online to see how your resume scores against a specific job description. Fix any parsing issues before submitting to real job postings.
