Applicant Tracking System (ATS) platforms have become nearly universal among large enterprises and increasingly common among small businesses. The ATS is the gatekeeper: get your formatting wrong, and your resume might never be seen. With nearly every Fortune 500 company and more than 45% of small businesses relying on ATS software, mastering the rules of crossing this digital bridge has never been more critical. According to JobScan’s 2025 Applicant Tracking System (ATS) Usage Report: Key Shifts and Strategies for Job Seekers, 97.8% of Fortune 500 companies use an ATS to manage applications, automate screening, and ensure compliance across large hiring volumes. Smaller organizations are also embracing these tools: a 2025 market overview by HRWebSoftware found that over 45% of small businesses (those with fewer than 100 employees) are using an ATS in some capacity to streamline recruiting, centralize candidate data, and compete more effectively for talent. For job seekers, understanding how an ATS works is the key to having your resume actually seen.

The ATS Challenge: A Digital Gatekeeper
With so much weight placed on getting through an ATS, it can be extremely intimidating to job seekers. Many candidates view the ATS as an insurmountable barrier, a system so particular and unforgiving that one wrong move could send their carefully crafted resume into a digital black hole, never to be reviewed by human eyes.
Preventing Your Resume From Digital Rejection
Many resumes that look beautiful to a human can become unreadable to the ATS if they contain formatting or content elements that confuse its parser. While each ATS has its own parsing engine and quirks, all of them rely on similar text extraction logic. That means by following a few universal formatting rules, your resume will parse successfully across most systems.
| Rule | The Details |
| Use a Simple, Single-Column Layout | Avoid tables, text boxes, and columns as they confuse parsers by breaking reading order. Keep everything in one continuous text flow from top to bottom. Left-align all text for consistency. |
| Stick to Standard Section Headings | Use conventional titles like: – Summary or Professional Summary – Experience – Education – Skills – Certifications Avoid creative labels like “Career Highlights” or “Notable Accomplishments”. ATS engines look for these standard keywords to categorize your information. |
| Save in the Right File Format | Preferred format: .docx (Microsoft Word) or text-based PDF (not scanned). Avoid: .pages, .odt, .rtf, .jpg, .png, or image-based PDFs. Tip: After saving your PDF, try to highlight text. If you can’t, it’s image-based and won’t parse. |
| Use Simple, Readable Design | Stick to standard fonts: Calibri, Arial, or Times New Roman (10–12 pt). Avoid heavy graphics, borders, logos, images, or icons. Use plain round bullets (•) Don’t use checkmarks, arrows, or emojis. Ensure all text is in high-contrast black or dark gray. |
| Structure Your Experience Clearly | Format each role consistently: E.g., Job Title | Company Name | City, State | Dates (e.g., Jan 2020 – Present) Resist the urge to bold all fields. When all items are bold, nothing stands out. Keep date formats consistent across the document. If you spell out the month in one place, make sure it is spelled out everywhere else. Use bullets to present your experience and accomplishments, starting with a present or past tense verb. |
| Keep Contact Information in the Body | Place your name, phone number, email, and LinkedIn URL at the top of the main document, not in a header or footer. ATS parsers often ignore headers/footers completely. |
| Avoid Hidden or Complex Elements | No embedded charts or text boxes. Don’t use hyperlinks to hide text (e.g., “click here” for LinkedIn). Write out the full URL. Don’t use white text or hidden keywords. It can look like spam and confuse parsing. |
With these formatting rules in hand, the ATS no longer has to feel like an insurmountable barrier. By following these straightforward guidelines, you can ensure your resume parses correctly, avoids digital rejection, and positions you for consideration
