Evaluating Resume Readability Scores with AI to Improve Recruiter Engagement
Recruiters sift through hundreds of applications daily. A single unreadable line can be the difference between a callback and a missed opportunity. In this guide we’ll explore how evaluating resume readability scores with AI can dramatically improve recruiter engagement, increase ATS pass‑rates, and ultimately land you more interviews.
Why Readability Matters in the Hiring Funnel
- 90% of recruiters admit they spend less than 30 seconds on an initial resume scan【Source】.
- ATS (Applicant Tracking Systems) often flag overly complex language, causing automatic rejections.
- Clear, concise wording signals strong communication skills—one of the top soft skills employers seek.
Bottom line: If a recruiter can’t quickly understand your value proposition, they’ll move on.
The AI Advantage: How Machines Measure Readability
Traditional readability formulas (Flesch‑Kincaid, Gunning Fog) rely on sentence length and word syllables. AI takes this a step further by:
- Contextual analysis – understanding industry‑specific jargon.
- Semantic scoring – evaluating how well key competencies match the job description.
- Visual layout assessment – checking font size, bullet consistency, and white‑space balance.
Resumly’s Resume Readability Test combines these techniques into a single, actionable score.
