ATS: 5 Tips to Optimize Your Resume and Get Past the Filter

If you're job hunting today, you've probably already heard of ATS without really knowing how to work with them. Yet these systems have become the real gatekeepers of your application. Understanding how they work and adapting your resume accordingly can mean the difference between a resume that lands on a recruiter's desk and one that disappears into digital limbo.

With Jobelia, you get an analysis of how well your resume matches each job posting, plus concrete recommendations to improve your score and get past the ATS filter.

What Is an ATS?

An ATS (Applicant Tracking System) is software used by over 90% of large companies and a growing number of SMEs to manage their hiring. When you apply online, your resume usually doesn't go straight to the recruiter: it first goes through the ATS, which analyzes it, extracts key information, and decides whether your profile matches the job criteria. Only candidates with a high enough score are then reviewed by a human.

This reality changes everything for job seekers: a visually perfect resume is no longer enough—it also needs to be readable and well scored by these systems.

1. Choose the Right Format (Simple and Readable)

The first golden rule is simplicity. Skip highly creative resumes with elaborate designs, unusual fonts, or complex layouts. Use a classic, chronological format with a clear structure and well-defined sections.

• Use standard fonts: Arial, Calibri, or Times New Roman.
• Save as Word (.docx) or PDF (generated from software, not a scan).
• Avoid headers and footers for important info: many ATS don't read them.
• Steer clear of text boxes, complex tables, and images to present your info: they're often ignored by the system.

An overly creative resume may have a parsing rate of only 20–30%, meaning most of your information is lost. Keep an "ATS-friendly" version of your resume.

2. Master the Art of Keywords

Keywords are at the heart of ATS scoring. To find them, read the job posting carefully: technical skills, software, certifications, qualifications, and action verbs. These terms should appear in your resume, ideally in their exact wording.

• If the posting mentions "Agile project management" and "Scrum Master certification", use those exact terms, not a vague "experience with agile methods".
• Weave keywords into your experience descriptions, skills section, and, when relevant, your job title.
• Watch out for keyword stuffing: modern ATS and recruiters spot it.

Jobelia compares your resume to the target job posting and shows you the essential keywords to include and suggested rewrites to boost your fit score.

3. Structure Your Sections Clearly

ATS look for explicit sections. Use standard, recognizable headings: "Work Experience", "Education", "Skills", "Certifications", "Languages". Avoid overly creative titles ("My Journey", "What I Can Do") that can confuse the system.

For each role:

• Exact job title + company name + dates (month/year).
• Descriptions in bullet points, with action verbs and quantified results when possible.

This structure makes it easier for the ATS to extract your data and improves your score.

4. Tailor Every Application (Personalization)

Sending the same resume to every job is one of the most common mistakes. Each role has its own requirements, and the ATS looks for different keywords per posting. Take time to customize your resume for each application: adjust keywords, reorder skills to highlight those that matter most for the role, and adapt your experience descriptions.

You don't need to rewrite everything: adjusting 20–30% of the content to align with the posting can significantly increase your response rate.

With Jobelia, you get a fit score and targeted advice (strengths, weaknesses, rewrites) for each posting so you can adapt your resume and maximize your chances of getting past the ATS filter.

5. Be Specific About Technical Skills

ATS place particular weight on technical skills and software. Don't settle for "Microsoft Office" or "management software". Be specific: "Advanced Excel (pivot tables, VBA macros)", "SAP ERP", "Python 3.x". List certifications with their full name and, if possible, certification number: their presence is often a deciding factor.

How Does ATS Scoring Work?

Once your resume is analyzed ("parsed"), the ATS assigns it a score based on match with the job criteria: keyword presence, years of experience, education, certifications. Only candidates above a certain score are passed to the recruiter. It's estimated that 75% of resumes are rejected by ATS before a human ever sees them—which is why optimizing yours matters.

Tools like Jobelia help you see your profile the way an ATS does: fit score, rewrite suggestions, and section ideas to better match the posting.

Pitfalls to Avoid

• Overly creative resume: infographics, charts, unusual layout = often poorly read by the ATS.
• Image or scanned PDF: the ATS can't read a JPG/PNG or non-editable PDF. Prefer a PDF generated from a word processor or .docx.
• Lying or exaggerating: if you get past the ATS and to the interview, inconsistencies will be spotted quickly.
• Skipping the cover letter: some ATS analyze it too; a tailored letter with the right keywords can strengthen your application.

What to Do After Applying

After submitting your application, you often get an automatic confirmation email. If you know the recruiter's or hiring manager's name, a short, professional message on LinkedIn ("I applied for the [job title] position and wanted to express my strong interest in joining your team") can set you apart—without being pushy.

ATS and Artificial Intelligence

ATS are evolving with AI: context analysis, recognition of synonyms or transferable skills. Still, stay close to the exact terms in the posting, as not all systems are equally advanced. Jobelia uses AI to analyze how well your resume matches the posting and suggest concrete improvements to get past the filter.

In Conclusion

The ATS is a necessary step in most hiring processes. Instead of seeing it as an obstacle, learn how it works and adapt your resume: simple format, keywords aligned with the posting, clear sections, and a personalized application for each role.
