Step-by-Step Process for Conducting a Resume ATS Compatibility Audit
Why an ATS audit matters – Over 75% of Fortune 500 companies use an Applicant Tracking System (ATS) to filter resumes before a human ever sees them. If your resume can’t speak the ATS language, it gets discarded, no matter how impressive your experience is. This guide walks you through a step-by-step process for conducting a resume ATS compatibility audit, giving you a repeatable framework you can apply to any job description.
1. Understand How ATS Works
Before you start the audit, know the three core functions of an ATS:
- Parsing – The system extracts text from your PDF/DOCX and maps it to fields (name, contact, experience, skills).
- Keyword Matching – It scores your resume against the keywords in the job posting.
- Ranking – Resumes with higher scores appear earlier in the recruiter’s view.
Pro tip: Use Resumly’s free ATS Resume Checker to see a real‑time parsing report.
2. Gather Your Materials
| Item | Why It’s Needed |
|---|---|
| Target job description | Provides the keyword set and required skills |
| Current resume (PDF & DOCX) | ATS parses both formats; testing both catches formatting issues |
| List of industry buzzwords | Helps you spot missing high‑impact terms |
| Access to a plain‑text editor (e.g., Notepad) | Allows you to strip hidden formatting |
Checklist – Pre‑Audit Prep
- Save your resume as both .docx and .pdf.
- Copy the full job posting into a separate document.
- Open a plain‑text editor for later use.
3. Extract Plain Text and Spot Hidden Formatting
- Open your .docx in Microsoft Word → Save As → Plain Text (.txt). This strips out hidden tables, text boxes, and graphics that confuse ATS parsers.
- Compare the plain‑text version with your original. Look for:
- Missing bullet points (they become random characters).
- Split headings (e.g., “Work Experience” turned into “WorkExperi‑ ence”).
- Do: Re‑write any section that loses meaning in plain text.
- Don’t: Rely on fancy fonts, images, or columns.
4. Keyword Mapping – The Heart of the Audit
4.1 Pull Keywords from the Job Posting
- Highlight nouns and verbs that appear 3+ times.
- Use Resumly’s Job Search Keywords tool to generate a keyword list automatically.
- Group them into three buckets: Hard Skills, Soft Skills, and Industry Terms.
4.2 Compare Against Your Resume
Create a two‑column table in your plain‑text editor:
| Keyword | Present in Resume? |
|---|---|
| Agile | ✅ |
| Scrum | ❌ |
| Data Analysis | ✅ |
| Stakeholder Management | ✅ |
| Python | ✅ |
| Machine Learning | ❌ |
Do: Add missing keywords where you have genuine experience. Don’t: Stuff unrelated buzzwords – ATS can penalize irrelevant terms.
5. Optimize Formatting for ATS Parsers
| Formatting Element | ATS‑Friendly Recommendation |
|---|---|
| Fonts | Use standard fonts like Arial, Calibri, or Times New Roman (10‑12 pt). |
| Headings | Use simple headings (e.g., Work Experience, Education) without decorative symbols. |
| Bullet Points | Use solid circles or hyphens; avoid custom icons. |
| Tables & Columns | Avoid – many ATS read them as a single block of text. |
| Images & Logos | Never – they are ignored and can break parsing. |
| File Name | Save as FirstName_LastName_Resume.pdf. |
Quick Fix: Run your resume through Resumly’s Resume Readability Test to ensure the structure is clean.
6. Run an Automated ATS Check
- Upload your .pdf to the ATS Resume Checker.
- Review the Parsing Score (out of 100) and the Keyword Match Rate.
- Note any Missing Sections flagged by the tool (e.g., “No contact information detected”).
- Export the report and keep it handy for the next revision round.
7. Revise, Refine, and Re‑Test
7.1 Revise Content
- Insert missing keywords naturally within bullet points.
- Replace passive language with action verbs (e.g., “Managed” → “Led”).
- Keep each bullet under 2 lines for readability.
7.2 Re‑Test
- Upload the revised file to the ATS checker again.
- Aim for a Parsing Score ≥ 90 and Keyword Match ≥ 80%.
- If scores plateau, consider using Resumly’s AI Resume Builder to generate a fresh, ATS‑optimized layout.
8. Final Quality Assurance Checklist
- Contact Info: Full name, phone, email, LinkedIn URL (no icons).
- Professional Summary: 2‑3 sentences with top 3 keywords.
- Work Experience: Reverse‑chronological, each entry includes Job Title, Company, Dates, Key Achievements with keywords.
- Education: Degree, institution, graduation year.
- Skills Section: List hard and soft skills matching the job posting.
- File Format: PDF (text‑based, not image‑based).
- File Name:
First_Last_Resume.pdf. - Length: 1‑2 pages for most roles; 3 pages only for senior/academic positions.

10. Frequently Asked Questions (FAQs)
Q1: Do I need to audit every resume I send? A: Yes. Tailoring your resume to each posting’s keyword set dramatically improves ATS match rates. Use the quick‑keyword checklist to speed up the process.
Q2: Can I use a graphic‑heavy design if the ATS can’t read it? A: Don’t. ATS parsers ignore images and may drop entire sections. Keep a clean, text‑based version for online applications and a design‑focused PDF for networking contacts.
Q3: How often should I run the ATS checker? A: Run it after every major edit and before each application. Small tweaks (adding a keyword) can shift your score by 5‑10 points.
Q4: Are there free tools besides Resumly? A: Yes, but Resumly’s suite (e.g., Buzzword Detector) is calibrated for modern job boards and provides actionable suggestions.
Q5: Does the ATS audit help with cover letters? A: Absolutely. The same keyword mapping applies. Check out Resumly’s AI Cover Letter feature for a seamless match.
Q6: What if I don’t have all the keywords listed? A: Only include keywords you can substantiate. Fabricating experience can be caught during interviews and harms credibility.
Q7: How do I know which ATS a company uses? A: Many companies list their ATS on job boards; otherwise, assume a common platform like Greenhouse, Lever, or iCIMS. All share similar parsing rules.
Q8: Can I automate the audit for multiple resumes? A: Yes. Resumly’s Auto‑Apply workflow can pair each tailored resume with its ATS report, saving hours of manual work.
