Understanding what an ATS resume checker evaluates is crucial for optimizing your application. These tools examine several key areas of your resume, each contributing to your overall score and chances of making it past the initial screening.
Content and keyword relevance
Resume checkers primarily analyze how well your document aligns with specific job descriptions. They scan for industry-specific terms and relevant keywords that match employer expectations. In fact, according to Jobscan's research, 99.7% of recruiters use keyword filters in their ATS to sort applications. The most effective checkers identify whether you've naturally incorporated keywords from job postings throughout your resume, particularly in your skills and experience sections. They evaluate both hard skills (technical abilities) and soft skills relevant to the position.
Formatting and file compatibility
An effective ATS resume checker examines whether your document uses ATS-friendly formatting. This includes verifying you've avoided elements that confuse parsing systems, such as tables, text boxes, columns, headers, footers, and graphics. They also check if you're using standard fonts like Arial, Calibri, or Times New Roman. Regarding file formats, quality checkers verify you've saved your resume as either .docx or .pdf—the two formats most compatible with ATS systems.
Skills section and section labeling
Resume checkers evaluate whether you've included a dedicated "Skills" section with clearly labeled headings. This organization helps ATS software quickly identify your qualifications. The best checkers ensure you've used standard section titles like "Work Experience" and "Education" rather than creative alternatives that might confuse automated systems. They also verify that essential resume sections appear in the main body of the document, as some ATS tools don't scan headers or footers.
Spelling, grammar, and tone
Beyond technical elements, ATS resume checkers assess language quality. They identify spelling errors, grammatical mistakes, and overly wordy sentences that might diminish your professionalism. According to JobHero's research, a professional resume must be completely error-free to pass both ATS and human review. Advanced checkers also evaluate your content's overall tone, ensuring it strikes the right balance between professional and engaging.
Use of active voice and avoiding buzzwords
Quality ATS checkers examine whether you've used active voice throughout your resume. Active verbs demonstrate ownership of actions and make your accomplishments clearer to both ATS systems and hiring managers. Additionally, they flag overused buzzwords and clichés that dilute your message, such as "team player," "hardworking," or "results-driven". Many employers now program their ATS to recognize strong action verbs as they better highlight specific accomplishments.
How to improve your ATS score
Passing the digital gatekeeper requires more than just good qualifications—you need a strategically optimized resume. With 99.7% of recruiters using ATS filters to find qualified candidates, knowing how to improve your score is critical for job search success.
Tailor your resume to the job description
Initially, add the exact job title from the posting to your resume headline. This simple step makes you 10.6 times more likely to get an interview. Customize your resume for each application by identifying keywords in the job description. In view of the fact that 76.4% of recruiters filter by skills, 55.3% by job title, and 50.6% by certifications, incorporating these exact terms is essential. Use both acronyms and full terms (like "ERP" and "Enterprise Resource Planning") to cover all bases.
Use measurable achievements in experience
Achievement-focused resumes stand out among task-oriented applications. Start each bullet point with strong action verbs and quantify your impact with specific numbers whenever possible. For example, instead of "Helped with customer service," write "Resolved 20+ customer complaints daily with a 93% satisfaction rate." These measurable results show employers not just what you did, but how well you performed.
Avoid design elements that confuse ATS
Simplicity is key for ATS compatibility. Avoid tables, columns, graphics, headers/footers, and uncommon fonts. Stick to standard section headings like "Work Experience" and "Education". As opposed to creative formats, use chronological or hybrid resume layouts. Save your file as a Word document (.docx) or PDF to ensure proper parsing.
Optimize resume length and bullet points
Keep your resume to 1-2 pages, as overly lengthy documents challenge ATS processing. Each bullet point should be 1-2 lines long for maximum readability. Sprinkle relevant keywords naturally throughout every section. First thing to remember: bullets should start with action verbs, avoid fillers like "various" or "multiple," and omit personal pronouns. This approach simultaneously improves ATS scoring and human readability.
