What are keywords?
A keyword is a word or phrase that users type into search engines to find information. Keywords are the foundation of search engine optimization (SEO) and paid search advertising — they help search engines understand a page's content and rank it accordingly. The same concept applies to resumes: keywords match a candidate's skills and experience to what an employer's ATS scans for in a job description, as Coursera (education platform) explains.
What are basic keywords?
Basic keywords are single words or short phrases with broad meaning. Think "shoes" or "marketing." They often have high search volume but strong competition. In a resume context, basic keywords might be general job titles or common skills like "team leadership." The Goodwill Industries International (nonprofit career service) stresses that the job posting itself is the best starting point for identifying these terms.
What are keywords and why are they important?
Keywords matter because they connect intent to content. On Google, 8.5 billion searches happen daily — each one a query containing a keyword. For a website, the right keyword means a page appears in relevant search results; for a job seeker, it can mean the difference between an application that surfaces in an ATS search and one that doesn't. Indeed (major job platform) notes that analyzing multiple job postings for the same role is effective for identifying the most frequently used terms.
A single missing keyword in your resume can cause an ATS to rank you below 50 other applicants — even if you have the exact experience. Matching the employer's language is not about gaming the system; it is about proving fit in the terms they defined.
The implication: keywords connect intent to action in both search and hiring.
What are the four types of keywords?
The four main types of keywords in SEO — informational, navigational, commercial, and transactional — classify search intent. The Semrush Blog (SEO analytics platform) explains that this classification helps marketers target the right audience at the right stage of their journey.
Informational keywords
- Used when the searcher wants to learn something. Example: "how to bake a cake."
- High volume, low purchase intent
- Common in blog content and educational resources
Navigational keywords
- Aim to reach a specific website or page. Example: "Facebook login."
- Brand terms or site-specific queries
- Low volume but high conversion intent from returning users
Commercial keywords
- Indicate research before a purchase. Example: "best running shoes."
- User is comparing options, not ready to buy immediately
- Critical for product review pages and comparison content
Transactional keywords
- Show intent to buy. Example: "buy iPhone 15."
- Highest conversion rate across all paid and organic channels
- Often drive PPC campaigns due to clear purchase signal
The pattern: each keyword type answers a different question. Informational keywords ask "what is," navigational ask "where is," commercial ask "which is best," and transactional ask "how do I buy." For resume keywords, the parallel is that recruiters also search with distinct intent — they might look for a hard skill (transactional: "Python developer") or a soft skill (commercial: "team lead with agile experience").
What are examples of keywords?
- Short-tail keyword: "shoes" — broad, high search volume, competitive.
- Long-tail keyword: "women's waterproof hiking boots size 8" — specific, lower competition, higher conversion rate. Long-tail keywords account for 70% of all web traffic.
- Resume keyword: "project management" — a skill recruiters often search for in ATS databases.
- LSI (Latent Semantic Indexing) keyword: "sneakers" for "shoes" — related terms that improve context understanding.
Indeed (job platform career advice) recommends using word cloud generators to visualize commonly occurring terms across multiple job descriptions — a tactic that turns raw data into a prioritized keyword list.
Short-tail keywords bring traffic but dilute focus. Long-tail keywords attract fewer visitors but capture people who already know what they want. On a resume, the trade-off is between "project manager" (competitive, generic) and "Agile-certified project manager with SaaS launch experience" (memorable, targeted).
The pattern: specific keywords tend to outperform broad ones for conversion, while broad keywords build awareness.
How do I find my keyword?
Finding keywords requires a systematic approach. For SEO, you can use dedicated research tools; for resume keywords, you analyze job postings. Both methods share a common structure: identify terms your audience uses and match them to your content or experience. For deeper guidance, see our article on What Keywords Should I Use.
Research Keywords with Keyword Planner
Google Keyword Planner is a free tool that provides search volume data, competition levels, and related term suggestions. The Google Ads Help Center (official Google resource) explains how to use it for discovering new keywords and getting forecasts. Enter a few broad terms, and the tool returns hundreds of variations with monthly search counts.
Where can I find keywords?
- Search autocomplete: Google's predictive suggestions show what people commonly search for.
- Related searches: Scroll to the bottom of Google results for alternative terms.
- Competitor analysis: Tools like Semrush reveal which keywords drive traffic to competing sites.
- For resumes, start with job descriptions: Goodwill Industries International (nonprofit career service) advises checking multiple listings for the same role to find recurring skills, tools, certifications, and responsibilities.
- Government databases: The U.S. Bureau of Labor Statistics (BLS) Occupational Outlook Handbook and O*NET OnLine can identify high-demand skills that serve as broader resume keywords.
How to extract resume keywords from job descriptions
- Copy at least ten job postings for your target role into a single document (iHire (career platform) suggests 10+).
- Highlight every recurring tool, skill, certification, and the exact job title (HugoUnoc ATS Checker Guide).
- Pay special attention to sections labeled "Requirements" and "Qualifications" — these carry the highest weight in ATS scoring (TailorForge (ATS strategy guide)).
- Include both the spelled-out term and its acronym (e.g., "search engine optimization (SEO)") to capture different recruiter search behaviors (HugoUnoc ATS Checker Guide).
- Use an ATS score checker like Upplai (resume optimization tool) to compare your resume against a specific job description and identify missing keywords.
What this means: a systematic approach to keyword finding yields better results for both SEO and job search. For more on keyword research methods, explore How to Do Keyword Research for Seo.
What is the keyword in a CV?
A resume keyword is a skill, qualification, or term that recruiters and ATS software actively search for. Grammarly (writing tool) groups resume keywords into four categories: job-related skills, action verbs, education requirements, and relevant experience. The distinction between a resume keyword and an SEO keyword is audience: one is scanned by a machine, the other by a search engine algorithm — but both must match the language used in the original query or job description.
Common resume keyword mistakes
- Keyword stuffing — repeating keywords unnaturally or listing skills without evidence. ResumeLime (career advice site) cautions that recruiters may view such resumes as misleading even if ATS scores are high.
- Using synonyms instead of exact wording from the job posting — "managing projects" instead of "project management" can reduce ATS matching strength (Resume Optimizer Pro).
- Ignoring job-specific keywords — general terms like "communication" may not pass ATS filters configured for "stakeholder communication."
- Failing to tailor for each application — a resume that uses the same keywords for every job misses context.
- Forgetting action verbs — "Led," "Designed," "Implemented" carry weight in both ATS and human review. Grammarly identifies action verbs as a distinct category.
Where to place keywords on a resume
- Skills section (10–12 highly relevant hard skills, as recommended by HugoUnoc ATS Checker Guide)
- Work experience bullet points supporting each keyword with a concrete accomplishment or metric
- Summary or objective — adding the target job title and employer name aligns with job-specific keywords (Rezi (resume builder))
- Education and certifications section
The catch: keywords must feel natural, not forced. Supporting each important term with a number or result transforms a keyword from a tag into evidence.
Confirmed facts vs. what is unclear
Confirmed facts
- Keywords are essential for SEO and resume screening.
- Google Keyword Planner provides real search volume data (Google Ads Help Center).
- The four types (informational, navigational, commercial, transactional) are widely accepted in SEO (Semrush Blog).
- Job descriptions are the best source for resume keywords (Goodwill Industries International).
- Long-tail keywords drive 70% of all web traffic.
- Resume keywords can increase callback rates by up to 40%.
What's unclear
- Exact percentage of recruiters who use keyword screening varies by industry.
- The effectiveness of LSI keywords is debated among SEO professionals.
- Real-world weighting differences between required vs. preferred keywords in specific ATS systems remain unpublished.
- How keyword stuffing quantitatively affects interview rates versus moderate use lacks hard statistics.
The takeaway: while some details remain debated, the core principles of keyword usage are well-established.
"A keyword is a word or term used for computer searches."
"The job posting is the single most important source for identifying resume keywords because it reflects the employer's requirements and what ATS filters are configured to scan for."
"Use both the target job description and comparable job descriptions for similar roles to gather a broader set of resume keywords."
"Support each important keyword with a concrete accomplishment or responsibility bullet, ideally including numbers or metrics."
For the job seeker preparing a resume, the choice is clear: extract keywords directly from job descriptions, prioritize terms repeated across multiple postings, and place them in skills and experience sections with supporting evidence. For the SEO practitioner, the same logic applies — align content with what your audience searches for using the four intent types as a filter. The concrete data, from Google's 8.5 billion daily searches to the 40% callback lift from resume keywords, shows one thing: the words you choose determine whether you are found.
Frequently asked questions
What is the difference between a keyword and a search term?
A keyword is the word or phrase you target in SEO or PPC campaigns. A search term is what a user actually types into the search bar. The two can differ — users may use synonyms, misspellings, or natural language that an advertiser's keyword match type accounts for.
Are long-tail keywords better than short-tail keywords?
Long-tail keywords (3+ words) have lower search volume but higher conversion rates because they capture specific intent. Short-tail keywords (1-2 words) drive more traffic but face stiffer competition. The best strategy uses both: short-tail for brand visibility and long-tail for conversion.
How many keywords should I target per page?
Focus on one primary keyword per page and 3-5 secondary related terms. Overloading a page with keywords dilutes its focus and can trigger spam signals. For resumes, target 10-12 highly relevant hard skills plus supporting action verbs and certifications.
What are negative keywords in PPC?
Negative keywords are terms you exclude from your ad campaign. If you sell premium shoes, adding "free" as a negative keyword prevents your ad from showing for searches like "free shoes" — saving budget and improving click quality.
Do keywords still matter for SEO in 2025?
Yes. Search engines still rely on keywords to understand content, but context and semantic relevance have grown more important. Keywords work alongside entities, topics, and user intent signals. For resumes, ATS systems still depend heavily on exact keyword matching.
How do I choose keywords for a resume?
Start with the job description for each application. Highlight every recurring skill, tool, certification, and responsibility. Check multiple postings for the same role to confirm which terms appear most often. Run your resume through an ATS score checker to identify gaps.
Can I use the same keywords for SEO and my CV?
Yes, with different contexts. An SEO keyword like "project management" targets search engines; on a resume, it targets recruiters and ATS. The principle is identical: match the language of the system you are trying to satisfy. For SEO, that means user queries; for a resume, that means the job description.
What is keyword stuffing in a resume?
Keyword stuffing means repeating a term unnaturally or listing skills without proving them through experience bullets. It can inflate ATS scores but damage human review — recruiters may view it as deceptive. Use each keyword once with supporting evidence.
The overarching lesson: whether you're optimizing a webpage or a resume, the words you use determine if you are found.
