1Keywords vs Buzzwords
Every resume article tells you to "use strong keywords." Almost none of them explain the difference between a keyword and a buzzword. It matters, because one gets you interviews and the other gets you ignored.
Keywords are specific, verifiable terms that describe what you've actually done or can do. HubSpot. Demand generation. $2M pipeline. Sprint planning. SQL. These are things a recruiter can check, an ATS can scan for, and a hiring manager can ask about in an interview.
Buzzwords are vague descriptors that could apply to literally anyone. "Results-driven." "Team player." "Detail-oriented." "Dynamic professional." These phrases appear on millions of resumes and tell the reader absolutely nothing about what makes you different. A recruiter has never pulled a resume from the pile because it said "self-starter."
The test is simple: could a stranger verify this term by looking at your work? "Salesforce" is verifiable. "Strong work ethic" is not. Fill your resume with the first kind. Cut every instance of the second.
2How ATS Keyword Matching Actually Works
Most people assume ATS systems are sophisticated AI that understands context and synonyms. They're not. The majority of ATS platforms do simple text matching. They look for exact phrases from the job description in your resume. That's it.
This means "project management" and "managed projects" may not register as the same thing. "Customer success" and "client satisfaction" might not match either. The ATS is scanning for strings of text, not interpreting meaning. Some newer systems like Greenhouse and Lever have smarter parsing, but plenty of companies still run older software that's essentially doing ctrl+F.
This is why mirroring the exact language from the job description matters so much. It's not about gaming the system or being dishonest. It's about speaking the same language the hiring team used when they wrote the posting. If they call it "demand generation" and you call it "lead creation," you might be describing the same work but the system won't know that.
One important caveat: the ATS is just the first gate. A human recruiter reviews every resume that makes it through. So your keywords need to work for both audiences. Exact matches for the ATS, natural context for the human.
3The Three Types of Keywords That Matter
Not all keywords carry equal weight. There are three categories worth focusing on, and they appear in a clear hierarchy.
- Hard skills and tools. These are the highest-value keywords on your resume. SQL, Figma, Salesforce, Python, Google Analytics, Tableau, AWS, Jira. If a tool or platform appears in the JD, it should appear on your resume (assuming you've actually used it). These are binary: either the ATS finds them or it doesn't.
- Function-specific terms. These describe the type of work, not just the tools. Demand generation, sprint planning, P&L management, content strategy, financial modeling, user research, A/B testing. These terms tell the recruiter you've done this specific kind of work before, not just that you own the software.
- Measurable results. Dollar amounts, percentages, headcounts, and timelines. "$2M pipeline," "40% conversion increase," "team of 12," "shipped in 6 weeks." These aren't traditional keywords, but they're what makes a recruiter stop scrolling. Numbers are the most powerful differentiator on any resume.
4How to Find the Right Keywords for Any Job
You don't need a keyword research tool. You need to read the job description carefully. Here's the process.
Read the full JD once without highlighting anything. Then go back and mark every term that appears more than once. If "cross-functional collaboration" shows up in both the responsibilities section and the requirements section, that's a priority keyword. Single-mention terms buried in a long list are usually filler.
Next, look at the first three bullets in the requirements section. These carry disproportionate weight because the hiring manager listed them first for a reason. Whatever skills or terms appear there should appear prominently on your resume, ideally in your top 3-5 bullet points.
Finally, check the job title itself. If the role is "Senior Growth Marketing Manager," the terms "growth marketing" and "senior" both matter. Your resume should reflect that level and that specialty, not just "marketing" in general.
For extra credit, look at 3-4 similar job postings from other companies. Terms that appear across multiple postings for the same role are industry-standard keywords you should have on your resume regardless of which specific job you're applying to.
5Keywords by Industry
Different fields have different keyword languages. Here's a quick reference for the most common industries. These aren't exhaustive, but they're a starting point for terms that show up repeatedly in job postings.
- Tech / Engineering: Python, AWS, CI/CD, Agile, microservices, REST APIs, Docker, Kubernetes, Git, system design, code review, unit testing
- Marketing: SEO, Google Analytics, content strategy, conversion rate, CAC, paid media, demand generation, marketing automation, HubSpot, A/B testing
- Sales: quota attainment, pipeline management, Salesforce, account management, revenue, prospecting, deal size, close rate, territory planning
- Finance: financial modeling, Excel, forecasting, compliance, audit, variance analysis, P&L, budgeting, GAAP, month-end close
- Product Management: roadmap, sprint planning, user stories, Jira, stakeholder alignment, OKRs, product-market fit, prioritization framework, customer discovery
- Design: Figma, user research, wireframing, design systems, prototyping, usability testing, accessibility, responsive design, information architecture
6The Keyword Stuffing Trap
You understand keywords matter. So you cram 47 of them into your skills section, drop a few into white text at the bottom of the page, and stuff your bullet points with every term from the JD. Please don't.
More keywords is not better. A resume that reads like a tag cloud gets past the ATS and then immediately gets rejected by the human recruiter. And the white-text trick? Most modern ATS systems strip formatting, so hidden keywords show up as a jumbled mess that makes you look dishonest.
Keywords should appear naturally, in context, attached to real work. Compare these two approaches.
- Bad: "Skills: demand generation, HubSpot, Google Ads, pipeline, revenue, growth, B2B, SaaS, marketing automation, ABM, content, SEO, analytics, campaigns, leads, MQL, SQL, conversion, funnel, strategy"
- Good: "Built demand generation program that drove $2M in pipeline using HubSpot and Google Ads. Managed full-funnel B2B marketing strategy across paid, organic, and ABM channels, growing MQL-to-SQL conversion by 34%."
7How ShouldApply Identifies Keyword Gaps
Finding keywords manually works but takes time. You have to read each JD closely, cross-reference it with your resume, and figure out which terms are missing. Multiply that by 10-15 applications per week and it adds up.
ShouldApply's scoring engine reads your resume against the job description and flags specific terms that are missing or underrepresented. It's not just checking for presence. It looks at whether the keyword appears in a meaningful context and whether it's positioned prominently enough to register with both the ATS and a human reader.
The result is a targeted list of changes. Not "add more keywords." More like: "The JD mentions 'stakeholder management' three times. Your resume doesn't use that phrase. You have 'worked with cross-functional teams,' which is related but not a direct match." That level of specificity turns a vague "add more keywords" into a 5-minute edit that actually moves the needle.
ShouldApply tells you exactly which keywords you're missing for any job. Stop guessing and get a specific list of what to add.

Frequently Asked Questions
There's no magic number. Focus on the 8-12 most important terms from the job description and make sure they appear naturally in your bullet points and skills section. Every keyword should be attached to a real accomplishment or genuine skill. If you can't describe a situation where you used the skill, don't list it.
Almost never. "Communication skills," "leadership," and "problem-solving" don't differentiate you from anyone. Every resume claims these. Instead, demonstrate soft skills through your bullet points. "Led team of 8 through product launch, coordinating across engineering, design, and marketing" shows leadership and communication without wasting a line on a generic claim.
Both matter, but for different reasons. The skills section is where the ATS looks first for hard skill matches. Bullet points are where the human recruiter confirms you've actually used those skills. You need keywords in both places. A skill listed in your skills section but never mentioned in your experience looks hollow.
If the JD mentions a specific certification, include it if you have it. AWS Certified, PMP, CPA, Google Analytics Certified. These are high-signal keywords because they're verifiable. Don't list certifications that aren't relevant to the role. A PMP certification on a graphic design resume just takes up space.
Your core technical skills stay consistent, but the priority order and supporting terms should change with each application. If one JD leads with "data visualization" and another leads with "data modeling," those are different resumes even if both are data analyst roles. The base keywords overlap, but the emphasis shifts.
