In 2025, submitting a resume isn’t enough, you need to optimize it for Applicant Tracking Systems (ATS) to even be seen by a human recruiter. With 90% of large companies using ATS software, keyword optimization is no longer optional. It’s the gatekeeper between you and your next job.
In this guide, we’ll walk you through what ATS systems are, how they work, and most importantly how to keyword-optimize your resume to beat them and land interviews.
What is an ATS, and Why Does It Matter?
An Applicant Tracking System (ATS) is software used by employers to filter, rank, and organize resumes. Before your application reaches a recruiter, it’s scanned for relevant keywords, job titles, skills, and formatting structure.
If your resume lacks the right terms, it might be rejected automatically, even if you’re a great candidate.
That’s why every job seeker in 2025 must focus on strategic keyword integration, especially if applying online or through job boards.
How ATS Scans Your Resume
ATS tools break your resume into sections like Education, Experience, and Skills, then scan the content to match:
- Exact phrases from the job description
- Industry-specific terminology
- Role-related tools and software
- Job titles and locations
If the match percentage is too low, your resume is automatically moved to the “No” pile.
Step-by-Step: How to Keyword Optimize Your Resume
Analyze the Job Description
Before applying, copy and paste the job posting into a document and highlight recurring words or phrases. These are likely the keywords the ATS is prioritizing.
Look for terms under:
- Required Skills
- Responsibilities
- Tools or Platforms
- Certifications
Example: If the job description includes “project management, Jira, stakeholder communication,” these terms should appear naturally in your resume (if applicable).
Place Keywords Strategically
Keyword stuffing doesn’t work. Instead, embed keywords naturally into your:
- Professional Summary
“Certified Project Manager with 3+ years using Jira and Agile methodologies.”
- Skills Section
Jira | Agile | Budget Management | Cross-Functional Team Leadership
- Experience Section
“Managed five cross-department projects using Agile frameworks and Jira tracking.”
Keep in mind: ATS systems prioritize contextual keyword use, not just isolated lists.
Use Standard Job Titles & Section Headings
Don’t try to be creative with titles like “Growth Hero” or “People Champion.” ATS may not recognize non-traditional headings.
Stick with:
- Work Experience
- Education
- Skills
- Certifications
And for job titles, use standard formats like “Marketing Manager” or “HR Coordinator.”
Avoid ATS-Killing Formats
Some formatting choices can prevent the ATS from reading your resume properly.
Avoid:
- Tables or columns
- Graphics or charts
- Text boxes
- Uncommon fonts or symbols
Do:
- Use a standard Word or PDF file (as requested)
- Use bullet points and consistent spacing
- Stick to clean formatting with simple section dividers

Tools to Check Keyword Optimization
There are online platforms like Jobscan and ResumeWorded that help evaluate your resume against a job post. However, these tools don’t fix deeper issues like poor phrasing, weak structure, or missing impact metrics.
That’s why expert support is often worth it, especially when you’re applying for competitive roles.
How Keywords Affect LinkedIn Too
Your resume isn’t the only place where keyword strategy matters. LinkedIn’s internal search algorithm uses profile keywords to rank you in recruiter searches.

Final Checklist: Is Your Resume Keyword-Optimized?
Before you submit your next job application, make sure your resume:
- Includes job-specific keywords
- Matches job titles and tools from the description
- Uses clean, ATS-friendly formatting
- Embeds keywords naturally across summary, experience, and skills
- Doesn’t rely solely on generic terms like “team player” or “hardworking”
Conclusion
In 2025, keyword optimization is the difference between getting ghosted and getting interviews. ATS software may be robotic, but the way you format and phrase your resume shouldn’t be. A strategic, keyword-rich resume proves you’re both technically aligned and professionally polished.
