How to Optimize Resume for ATS

In today’s hiring process, writing a strong resume is not enough. It also has to be readable by software.

That software is called an Applicant Tracking System, or ATS. It is the first filter many companies use before a recruiter even opens a resume. If your resume is not formatted properly or does not contain the right keywords, it may never reach a human reviewer.

That is why ATS resume optimization matters. Whether you are trying to improve resume for ATS, improve resume ATS score, or simply make sure your application gets seen, the goal is the same: make your resume easy for both software and people to understand.

At FirstCall HR, we see this issue often. Many candidates have the right skills, but their resumes are not built in a way that helps them pass the ATS. The good news is that this can be fixed with the right structure, the right wording, and the right level of tailoring.

What is an ATS?

ATS stands for Applicant Tracking System.

It is software used by recruiters and hiring managers to collect, sort, scan, and manage applications. Instead of manually checking every resume from the beginning, companies use ATS tools to organize applicants and identify profiles that match the role.

The system compares your resume against the job description. Based on that comparison, it helps recruiters sort candidates by relevance.

In simple terms, ATS acts like a filter. A resume that is clear, relevant, and easy to read has a much better chance of moving forward.

How does ATS work?

An ATS is designed to make hiring faster and more organized.

Here is the usual process:

• The recruiter enters the job details into the system.
• Skills, qualifications, and experience requirements are added as keywords.
• Candidates submit resumes through a website or job portal.
• The ATS scans each resume and checks for matches.
• It ranks or filters candidates based on fit.

Some recruiters review every application, but in many cases, the ATS does the first round of screening automatically. That means your resume needs to make a strong impression very quickly.

Why do companies use ATS?

Companies use ATS because it saves time and improves hiring efficiency.

The main benefits include:

• faster screening of applications,
• easier candidate tracking,
• better organization of resumes,
• reuse of job descriptions across similar roles,
• posting jobs on multiple platforms,
• storing candidate history,
• ranking applicants by fit,
• and making interview scheduling easier.

For recruiters, ATS reduces manual work. For candidates, it means the resume has to be written with care if it is going to make it past the first screen.

What is an ATS-friendly resume?

An ATS-friendly resume is a resume that can be read and understood by recruitment software without confusion.

That means the format is simple, the headings are standard, the structure is clean, and the content is aligned with the role.

A good ATS resume should work for both audiences:

• the ATS, which scans the file,
• and the recruiter, who reads the shortlisted profile.

That balance is what makes a resume effective.

How to optimize resume for ATS

There is no single trick that will magically improve your resume. Instead, ATS resume optimization comes from a few core habits done consistently.

1. Use the right keywords

Keywords are the foundation of ATS optimization.

The ATS looks for words in your resume that match the job description. These usually include:

• skills,
• tools,
• software,
• certifications,
• qualifications,
• job titles,
• and role-specific experience.

For example, if a job description mentions:

• performance marketing,
• SEO,
• Google Ads,
• CRM,
• lead generation,

then those terms should appear in your resume if they are part of your actual background.

The best place to pull keywords from is the job description itself. Use the language the employer is already using. That improves your chances of matching what the ATS is looking for.

It is also smart to include both short and long forms when relevant. For example:

• Search Engine Optimization and SEO
• Customer Relationship Management and CRM
• Digital Marketing and Performance Marketing

This helps your resume stay readable across different systems.

2. Keep the formatting simple

A creative resume may look attractive to a person, but ATS software often struggles with complex layouts.

Avoid:

• images,
• charts,
• tables,
• columns,
• text boxes,
• icons,
• and decorative graphics.

A single-column resume is usually the safest format.

If you want to improve resume for ATS, formatting is one of the first things to fix. A resume can be visually neat and still be hard for software to read if it uses too many design elements.

3. Use standard headings

ATS software understands familiar section headings much better than creative labels.

Use simple headings like:

• Summary
• Skills
• Work Experience
• Education
• Certifications
• Achievements

Clear headings help the software identify where each section begins, and they also help the recruiter scan your profile faster.

4. Choose a readable font

Use a font that is easy to scan and widely supported.

Good choices include:

• Arial
• Times New Roman
• Calibri
• Georgia

Avoid decorative or unusual fonts. They can look stylish, but they may not scan well.

A clean font is one of the simplest resume tips and tricks that still makes a real difference.

5. Use bullet points for your work experience

Bullet points make a resume easier to scan and easier to understand.

A good bullet point should be short, specific, and result-oriented. For example:

• Increased qualified leads through targeted paid campaigns
• Managed email campaigns that improved engagement
• Coordinated with sales teams to streamline lead follow-up
• Supported SEO implementation and website content updates

This is much better than a long paragraph because both ATS software and recruiters can process it more quickly.

6. Tailor your resume for every job

A generic resume usually performs worse than one that is tailored to the role.

Every job has slightly different keywords, priorities, and expectations. If you are applying for multiple roles, update your summary, skills section, and work experience to match the specific opening.

This is one of the most effective ways to maximize resume for ATS.

You do not need to rewrite the whole document every time. But you should adjust the parts that matter most to the role.

7. Put important details in the main body

Some ATS platforms struggle to read information placed in headers or footers.

That means your:

• name,
• phone number,
• email address,
• location,
• and LinkedIn profile

should appear clearly in the main body of the resume.

Do not hide critical information inside design elements. If the ATS cannot find it, the recruiter may not either.

8. Save the resume in the right file format

File format matters too.

If the job posting does not mention a preference, .docx is usually the safest choice because it is generally easier for ATS to process.

If you submit a PDF, make sure it is text-based and not just a scanned image. A scanned file can cause parsing problems.

Choosing the right format is part of how to optimize your CV for ATS as well. The file should be easy to open, easy to scan, and easy to interpret.

9. Match your summary to the role

Your summary should give a recruiter a quick sense of who you are and what kind of role you are targeting.

For example, if you are applying for a digital marketing role, your summary should mention relevant strengths like campaign management, SEO, analytics, or lead generation. If you are applying for a finance role, it should reflect finance-related experience.

A strong summary helps the ATS and the recruiter understand your profile more quickly.

10. Repeat relevant skills naturally

If a skill is truly part of your experience, it should appear in more than one section of the resume.

For example, if you know SEO, you can mention it in:

• the summary,
• the skills section,
• the work experience section,
• and certifications or projects, if relevant.

This reinforces the keyword without making the resume feel forced.

That is one of the smartest ways to improve resume to pass ATS without overstuffing it.

What keywords should you include?

The best keywords usually come directly from the job description.

They may include terms related to:

• technical skills,
• software tools,
• industry knowledge,
• certifications,
• job titles,
• responsibilities,
• and achievements.

For example, a marketing resume may include:

• performance marketing,
• Google Ads,
• Meta Ads,
• SEO,
• campaign optimization,
• lead generation,
• CRM,
• and email marketing.

A tech resume may include:

• Java,
• SQL,
• Spring Boot,
• API development,
• debugging,
• testing,
• and deployment.

The important thing is to only use keywords that genuinely reflect your background. ATS systems are designed to match relevance, not just repetition.

Can you cheat ATS?

People try, but it is not worth it.

Some candidates hide keywords in white text, paste job descriptions into their resumes using invisible formatting, or overload the document with unrelated terms.

These tricks usually do not help. In many cases, they can hurt your chances if a recruiter notices them.

A better strategy is to write a resume that is clear, honest, and aligned with the role.
