Are you submitting dozens of applications but not hearing back from employers? You might be hitting a roadblock you can’t see: the Applicant Tracking System (ATS). As the first and most important gatekeeper in today’s hiring process, ATS software decides whether your resume is even seen by a human recruiter. If your resume isn’t optimized, it could be filtered out before you get a chance to shine.

What is an ATS and Why Does It Matter?

An ATS (Applicant Tracking System) is software used by the majority of employers—from global corporations to nimble startups—to screen and organize job applications. These systems scan your resume for relevant information, keywords, and structure before any hiring manager reviews your credentials. Optimizing your resume for ATS is a must if you want your application to land in the hands of decision-makers.

The Best Resume Format for ATS

Use a clean, traditional layout: Stick to standard resume sections in a single-column format.

Choose basic fonts: Arial, Calibri, or Times New Roman are always safe bets. Avoid decorative or custom fonts.

Save your resume as a .docx file: Unless otherwise specified, this format is most easily read by ATS.

Avoid graphics, tables, headers, and footers: These design elements can confuse ATS software.

Consistent, conventional section titles: Stick with “Work Experience,” “Education,” “Skills,” etc.

For best results, let professionals design your resume. Explore Prosumely’s resume writing services to ensure your document passes ATS filters and impresses recruiters.

How to Use Keywords Effectively

Including the right keywords is critical for beating the ATS. These systems search for specific skills and terms pulled directly from the job description.

Tailor your resume for every job application by identifying and including the top keywords listed in the job ad.

Balance technical and soft skills—both matter for scoring well with ATS.

Use synonyms and related phrases where possible (e.g., both “Project Manager” and “Project Management”).

Integrate keywords naturally into your bullet points and summary, not just in your skills section.
