Cover Letter Keywords: What ATS Systems Actually Scan For

What Keywords Do ATS Systems Actually Look For?

Most ATS systems—Workday, Taleo, Greenhouse, Lever—scan your cover letter for keyword matches before any human sees it. If you're missing the right keywords, your application gets auto-rejected in about 6 seconds.

67% of applications never reach human reviewers. They're filtered out by ATS software that scans for specific keyword patterns from the job description.

The good news: ATS keyword scanning is predictable. Once you understand how systems like Workday and Greenhouse parse text, you can optimize your cover letter to pass the filter. This guide shows you exactly which keywords matter and where to place them.

Quick answer: ATS systems scan for job title keywords, required skills (technical and soft), industry-specific terms, and action verbs. You need 8-12 keywords from the job description, naturally integrated into your cover letter. Most systems can't parse tables, text boxes, or custom fonts—stick to plain text with standard formatting.

Universal Power Keywords That Work Across Industries

These action verbs consistently score well in ATS systems because they signal specific types of experience. Here's why they work and how to use them:

The 10 Power Keywords (Quick Scan)

Here are all 10 keywords organized by ATS priority. Scroll down for detailed explanations and examples of each.

🔥 Very High Priority (Use these if they match your experience)

• Led / Spearheaded → Leadership roles
• Drove → Revenue/Growth roles
• Managed → People/Project roles

⭐ High Priority (Work across most roles)

• Achieved → Results-focused roles
• Implemented → Technical/Operations
• Collaborated → Team-oriented roles
• Developed → Technical/Creative
• Analyzed → Data/Analytics roles

✓ Medium-High Priority (Role-specific but effective)

• Optimized → Efficiency-focused
• Delivered → Project-based roles

1. "Achieved"

Category: Results & Outcomes | ATS Priority: High

Why it works: Signals results-orientation. ATS systems flag this as a "quantifiable outcome" keyword. Workday and Taleo specifically scan for achievement verbs in the first paragraph.

How to use: Always pair with a metric. Generic "achieved goals" won't help—be specific.

✅ Good example:

"Achieved 140% of sales quota in Q4 2025"

❌ Weak example:

"Achieved my goals and exceeded expectations"

Pro tip: If you can't quantify it, use a different keyword. "Achieved" without numbers scores lower in ATS systems.

---

2. "Led" / "Spearheaded"

Category: Leadership | ATS Priority: Very High

Why it works: Demonstrates leadership without requiring a manager title. Many ATS systems (especially Greenhouse) have leadership detection algorithms that flag these keywords separately.

How to use: Use even if you weren't officially managing people. Leading projects, initiatives, or cross-functional work counts.

✅ Good example:

"Led a cross-functional initiative to streamline onboarding processes"

❌ Weak example:

"Led meetings and coordinated with team members"

Pro tip: "Spearheaded" is slightly stronger than "led" in ATS scoring, but both work. Use whichever feels more natural.

---

3. "Implemented"

Category: Execution & Operations | ATS Priority: High

Why it works: Shows execution capability, not just ideas. Systems like Greenhouse score this higher than "suggested" or "proposed" because it implies completion.

How to use: Connect to a specific system, process, or tool. Name what you implemented.

✅ Good example:

"Implemented a new CRM system, reducing data entry time by 50%"

❌ Weak example:

"Implemented various improvements to streamline operations"

Pro tip: Implementation keywords work best when paired with the tool/system name. "Implemented Salesforce" scores higher than "implemented systems."

---

4. "Collaborated"

Category: Teamwork | ATS Priority: High

Why it works: Essential for team-oriented roles. Most ATS systems scan for collaboration keywords separately from individual achievement keywords.

How to use: Name the teams or departments you worked with. Specificity matters.

✅ Good example:

"Collaborated with engineering, design, and product teams to launch features on time"

❌ Weak example:

"Collaborated with others to complete projects"

Pro tip: Some ATS systems (like Lever) scan for collaboration keywords in the second paragraph. Place it strategically based on the job description's emphasis on teamwork.

---

5. "Optimized"

Category: Efficiency & Improvement | ATS Priority: Medium-High

Why it works: Signals improvement mindset. ATS systems flag optimization keywords for roles requiring efficiency and process improvement.

How to use: Show before/after metrics when possible. Optimization implies measurable improvement.

✅ Good example:

"Optimized email marketing campaigns, increasing open rates from 18% to 32%"

❌ Weak example:

"Optimized processes to improve efficiency"

Pro tip: Optimization keywords score highest when paired with metrics. If you don't have numbers, use "improved" instead—it's less specific but still effective.

---

6. "Drove"

Category: Impact & Growth | ATS Priority: Very High

Why it works: Implies initiative and measurable impact. Stronger than "contributed to" in ATS scoring because it suggests you were the primary driver.

How to use: Connect to revenue, growth, or efficiency metrics. "Drove" implies ownership.

✅ Good example:

"Drove $2.5M in new revenue through strategic partnership development"

❌ Weak example:

"Drove initiatives that helped the company grow"

Pro tip: "Drove" works best for business impact. For technical roles, "developed" or "built" might be more appropriate.

---

7. "Managed"

Category: Leadership & Oversight | ATS Priority: Very High

Why it works: Versatile keyword that works for people, projects, or resources. High ATS match rate because it's one of the most-scanned leadership keywords.

How to use: Specify what you managed (team size, budget, project scope). Vagueness hurts your score.

✅ Good example:

"Managed a portfolio of 45 enterprise accounts worth $8M ARR"

❌ Weak example:

"Managed various projects and responsibilities"

Pro tip: "Managed" scores highest when paired with numbers (team size, budget, project count). If you managed people, include team size. If you managed projects, include project count.

---

8. "Developed"

Category: Creation & Building | ATS Priority: High

Why it works: Shows building and creation capability. ATS systems score this for technical and creative roles separately from execution keywords.

How to use: Name what you developed (systems, processes, content). Be specific about the deliverable.

✅ Good example:

"Developed and maintained documentation that reduced support tickets by 40%"

❌ Weak example:

"Developed solutions to improve workflow"

Pro tip: "Developed" works for both technical (software, systems) and creative (content, processes) roles. It's more versatile than "built" or "created."

---

9. "Analyzed"

Category: Data & Insights | ATS Priority: High

Why it works: Critical for data-driven roles. ATS systems flag analytical keywords separately from creative keywords, so this helps you match the right role type.

How to use: Specify what data you analyzed and what insights you found. Connect analysis to outcomes.

✅ Good example:

"Analyzed customer behavior data to identify upsell opportunities worth $500K"

❌ Weak example:

"Analyzed data to find trends and patterns"

Pro tip: "Analyzed" scores highest when paired with the data source (customer data, sales data, user behavior) and the outcome (insights, opportunities, recommendations).

---

10. "Delivered"

Category: Completion & Reliability | ATS Priority: Medium-High

Why it works: Emphasizes completion and reliability. ATS systems score delivery keywords for project-based roles where on-time completion matters.

How to use: Include timeline and budget context when relevant. "Delivered" implies successful completion.

✅ Good example:

"Delivered 15 projects on time and under budget over 18 months"

❌ Weak example:

"Delivered results and met deadlines"

Pro tip: "Delivered" works best for project-based roles. For ongoing responsibilities, "managed" or "maintained" might be more appropriate.

How to Find the Right Keywords for Your Cover Letter

Finding keywords isn't guesswork—it's pattern recognition. Here are four methods that actually work:

Method 1: Mine the Job Description (Most Important)

What to look for:

• Words that appear 2+ times (these are priority keywords)
• Skills listed as "required" vs. "preferred" (required = must include)
• Industry jargon and acronyms (ATS systems scan for these)
• Action verbs they use (mirror their language exactly)
• Job title variations (they might say "Marketing Manager" and "Marketing Lead"—include both)

Pro tip: Copy the job description into a word counter. Words appearing 3+ times are likely ATS-scanned keywords.

Method 2: LinkedIn Research

What to check:

• Skills sections of people in similar roles (these are often ATS keywords)
• Language patterns in their summaries (how do they describe their work?)
• Endorsements and recommendations (what keywords do others use?)

Why this works: If multiple people in the role use the same terms, those terms are likely ATS-scanned.

Method 3: Company-Specific Research

Where to look:

• Company values page (cultural fit keywords)
• Product/service terminology (they want you to understand their language)
• Blog posts and press releases (how do they describe their work?)

Why this matters: Some ATS systems (especially Greenhouse) scan for company-specific terminology as a culture fit signal.

Method 4: Use Keyword Extraction Tools

Tools like WhatIsACoverLetter automatically:

• Extract keywords from job descriptions
• Prioritize them by ATS importance (not just frequency)
• Identify which keywords you're missing from your draft
• Show you where to place them for maximum impact

When to use this: If you're applying to multiple jobs, manual keyword extraction gets tedious. Automation saves time and catches keywords you'd miss.

The Keyword Density Sweet Spot

There's a balance between too few keywords (ATS rejection) and too many (human rejection for keyword stuffing).

How ATS systems score keyword density:

Most ATS systems use a scoring algorithm that looks for:

• 8-12 keywords from the job description (optimal range)
• 65-75% keyword match rate (you don't need every single keyword)
• Natural integration (keywords should read naturally, not forced)

Rule of thumb:

• Include each high-priority keyword 2-3 times (but vary the context)
• Include medium-priority keywords 1-2 times
• Ensure 65-75% of required keywords are present
• Never repeat a keyword more than 4 times (triggers spam filters)

What happens if you overdo it: Some ATS systems (like Workday) flag documents with excessive keyword repetition as "spam" and reject them automatically. Natural language always wins.

Keywords to Avoid

Some words have become so overused they've lost meaning:

❌ Passionate - Show, don't tell ❌ Self-starter - Demonstrate with examples ❌ Team player - Use "collaborated" instead ❌ Detail-oriented - Prove it with specific accomplishments ❌ Hard-working - Let your achievements speak ❌ Go-getter - Too informal ❌ Think outside the box - Cliché

Keyword Placement Strategy: Where ATS Systems Look First

Where you place keywords matters because ATS systems don't read linearly—they scan for keyword density in specific sections.

How ATS systems parse cover letters:

Most ATS systems (Workday, Taleo, Greenhouse) scan in this order:

1. Header section (if present) - Job title keywords here score highest
2. First 100 words - Highest keyword weight
3. Body paragraphs - Medium keyword weight
4. Closing - Lower weight, but still scanned

Optimal placement:

1. Opening paragraph: Job title + top 2-3 required skills

   • This is where ATS systems assign the highest keyword weight
   • Example: "I'm applying for the [Job Title] position. With 5 years of [Skill 1] and [Skill 2] experience..."

2. Second paragraph: Technical skills + experience level + tools

   • ATS systems scan this section for hard skills
   • Example: "My experience with [Tool 1], [Tool 2], and [Tool 3] includes..."

3. Third paragraph: Soft skills + cultural keywords + achievements

   • Include soft skills mentioned in the job description
   • Example: "I've [achievement verb] [result] while [soft skill keyword]..."

4. Closing: Role title + company name (1-2 times max)

   • Reinforces the match without keyword stuffing
   • Example: "I'm excited about the opportunity to contribute to [Company Name] as a [Job Title]."

Pro tip: Some ATS systems (especially Lever) give extra weight to keywords in the first sentence. Start strong.

Quick Keyword Checklist

Before submitting your cover letter, verify:

• Job title appears in opening paragraph
• 3-5 technical skills from requirements are included
• At least 2 soft skills are mentioned
• Company name appears 1-2 times
• Industry-specific terms are present
• Action verbs lead most achievement statements
• No keyword appears more than 4 times
• All keywords read naturally in context

Pro Tips: What Most People Get Wrong

Tip 1: Mirror Their Exact Language (Don't Paraphrase)

The mistake: People think "project management" and "managing projects" are the same. ATS systems don't.

Why it matters: ATS systems match exact phrases, not synonyms. If the job description says "project management," use "project management"—not "managing projects" or "project coordination."

Example:

• ❌ Job says "customer relationship management" → You write "CRM" or "client relations"
• ✅ Job says "customer relationship management" → You write "customer relationship management" (at least once, then you can use CRM)

Tip 2: Include Keyword Variations (But Prioritize Exact Matches)

Some ATS systems scan for variations, but exact matches score higher.

Strategy: Use the exact phrase from the job description 2-3 times, then include variations 1-2 times.

Example: If the job mentions "customer service" and "client relations," include both—but prioritize whichever appears more frequently in the job description.

Tip 3: Update Keywords for Every Single Application

The mistake: Using the same keywords for similar roles at different companies.

Why it fails: Different companies use different terminology. A marketing role at a tech company might emphasize "growth marketing" while a marketing role at a traditional company emphasizes "brand management." Same function, different keywords.

Solution: Extract keywords fresh for every application. Yes, it takes 5 extra minutes. Yes, it's worth it.

Tip 4: Test Your Cover Letter Before Submitting

The problem: You don't know if your keywords are actually being detected.

Solution: Use ATS simulation tools (like WhatIsACoverLetter's keyword checker) to see which keywords are detected before you submit. This catches formatting issues that prevent keyword detection.

What to check:

• Are all required keywords present?
• Are keywords being detected despite formatting?
• Is keyword density in the optimal range?

Common Keyword Mistakes That Get Applications Rejected

Mistake 1: Keyword Stuffing

What it looks like: "I have project management project management experience in project management..."

Why it fails: ATS systems flag excessive repetition as spam. Most systems reject documents with keywords repeated more than 4-5 times.

Fix: Use keywords naturally. Vary your sentence structure.

Mistake 2: Using Synonyms Instead of Exact Terms

What it looks like: Job says "software engineering" → You write "software development"

Why it fails: ATS systems match exact phrases. "Software engineering" and "software development" are different keywords.

Fix: Use the exact terminology from the job description.

Mistake 3: Ignoring Soft Skills

What it looks like: Only including technical keywords, ignoring "collaboration," "communication," "leadership"

Why it fails: Many ATS systems (especially Greenhouse) scan for soft skills separately. Missing them lowers your score.

Fix: Include 2-3 soft skills mentioned in the job description.

Mistake 4: Formatting That Breaks Keyword Detection

What it looks like: Keywords in text boxes, tables, or custom fonts

Why it fails: ATS systems like Workday and Taleo can't parse text boxes or tables reliably. Custom fonts sometimes fail OCR.

Fix: Use plain text with standard fonts (Arial, Calibri, Times New Roman). No text boxes, no tables, no fancy formatting.

Frequently Asked Questions

How many keywords should I include in my cover letter?

Answer: Aim for 8-12 keywords from the job description. You don't need every single keyword—65-75% keyword match rate is optimal. More than 15 keywords usually triggers spam filters.

Do I need to include keywords in a specific order?

Answer: No, but placement matters. Keywords in the first 100 words score higher than keywords in the closing paragraph. Put your most important keywords (job title, top 3 skills) in the opening paragraph.

Can I use the same keywords multiple times?

Answer: Yes, but limit repetition. Use high-priority keywords 2-3 times, medium-priority keywords 1-2 times. Never repeat a keyword more than 4 times—that triggers spam detection.

What if the job description doesn't list specific keywords?

Answer: Extract keywords from the "Requirements" and "Preferred Qualifications" sections. Also check the job title, company description, and any "About This Role" sections. If keywords aren't obvious, look at similar job postings for that role.

Do ATS systems scan for synonyms?

Answer: Some do, but exact matches score higher. If the job description says "project management," use "project management" (exact match) rather than "managing projects" (synonym). You can include both, but prioritize exact matches.

How do I know if my keywords are being detected?

Answer: Use an ATS simulation tool to check keyword detection before submitting. Some tools (like WhatIsACoverLetter) show you which keywords are detected and which are missing.

Should I include keywords even if they don't fit naturally?

Answer: No. Forced keywords hurt readability and can trigger spam filters. If a keyword doesn't fit naturally, find a different way to include it or skip it if it's low-priority. Natural language always beats keyword stuffing.

Do different ATS systems scan differently?

Answer: Yes. Workday focuses heavily on exact phrase matching. Greenhouse scans for soft skills separately. Taleo uses weighted keyword scoring. Lever prioritizes keywords in the first sentence. The good news: including 8-12 keywords naturally works across all systems.

Can I use acronyms instead of full keywords?

Answer: Use both. Include the full phrase (e.g., "customer relationship management") at least once, then you can use the acronym (CRM) elsewhere. Some ATS systems scan for both, but full phrases score higher.

What if I'm missing some required keywords?

Answer: If you're missing 1-2 required keywords, you might still pass if you have strong matches elsewhere. If you're missing 3+ required keywords, your application will likely be rejected. Either find a way to include them naturally, or reconsider if you're qualified for the role.
