How to Find Keywords in a Job Description: A Ten-Minute Method
To find the keywords in a job description, read it once for the shape of the job, then read it again with a marker and underline every noun a recruiter could type into a search box: tools, methods, systems, credentials, domains and the job title itself. Count which ones repeat, note which sit under “requirements”, and keep only the ones you can honestly claim. A typical posting gives eight to fifteen candidates, and you will use about six.
That is the whole method, and you can do it with a pen. The rest of this guide shows each step, with a worked example, so you can repeat it on every application without it turning into an evening’s work.
What counts as a keyword
A keyword is a phrase a person or a program would use to decide whether your resume matches the posting. Most of them are plain nouns and noun phrases:
- Tools and software: Zendesk, Excel, Figma, Python.
- Methods and practices: cohort analysis, root cause analysis, Agile, A/B testing.
- Credentials: RN licence, PMP, CPA, forklift certification.
- Domains and scale: B2B SaaS, multi-site retail, 200-bed hospital.
- The title itself, written the way the posting writes it.
Adjectives rarely qualify. Nobody searches for “motivated team player”. They are still worth a glance, because a posting that stresses “fast-paced” ten times is telling you about the job, but they belong in your summary line, not in a keyword list.
How to find the keywords in a job description, step by step
1. Read for the job first
Before you mark anything, answer one question in a sentence: what would I be doing on a Tuesday? “Answering tier-two support tickets and training new agents” is a good answer. This sentence is your filter. A phrase that does not connect to it is probably boilerplate, and boilerplate is where keyword hunting goes wrong.
2. Underline the nouns, then circle the repeats
On a second pass, underline every searchable noun. Then circle any that appear more than once. A skill named in the title, the summary and the requirements list is the posting’s centre of gravity. Something mentioned once, in the last bullet, is a footnote.
A short invented example:
Customer Support Specialist. You will handle tier-two escalations in Zendesk, document fixes in our knowledge base and train new agents. Required: two years of customer support experience, Zendesk or similar ticketing tools, strong written communication. Preferred: Salesforce, experience writing help-centre articles.
Underlined, that gives: customer support specialist, tier-two escalations, Zendesk, knowledge base, train new agents, ticketing tools, written communication, Salesforce, help-centre articles. Circled for repeating: Zendesk (twice, counting “ticketing tools” as its category).
3. Sort them into three buckets
Not every keyword deserves the same space on your page. Sort what you underlined:
| Bucket | Where it came from | What to do |
|---|---|---|
| Must-have | ”Required”, “must have”, or in the job title | Put it on page one if you have it |
| Preferred | ”Nice to have”, “bonus”, “familiarity with” | Include it when true |
| Context | Team, culture, mission, tone | Use it in the summary or cover letter |
In the example, Zendesk and customer support are must-haves, Salesforce and help-centre articles are preferred, and “train new agents” is a duty that tells you which bullet to move to the top.
4. Look for the same skill under two names
Postings and resumes often describe the same work with different words. “Customer implementation” and “client onboarding” are one job. “Ticketing tools” and “helpdesk software” are one category. For each must-have, ask whether your resume already says it in another form.
If both labels are genuinely yours, use both once: “Client onboarding (customer implementation)”. The reader finds it under either phrase, and it still reads like a normal sentence. Our guide to tailoring a resume to a job description covers where those edits go.
5. Match each keyword to something you did
Now turn the list into a two-column check:
| Keyword | Where I did it | Ready to claim? |
|---|---|---|
| Zendesk | Two years at my current employer, daily | Yes |
| Knowledge base | Wrote about 20 articles in 2024 | Yes |
| Salesforce | Used it once during a training week | Only if asked, not as a headline skill |
| Help-centre articles | Same as knowledge base | Yes, use both phrases |
A keyword you cannot defend in an interview is a trap you set for yourself. If you have never touched it, leave it out. If you have touched it lightly, give it a modest place in the skills list and no more. A posting that asks for seven things rarely expects every candidate to have all seven, and an honest five beats a padded seven.
6. Put them where they get read
Once you have your final list of six or so, place them in order of importance:
- The summary line, which names the role and one or two must-haves.
- The first bullet under each relevant job, which is the one a skimmer reads.
- The skills section, with the posting’s required tools first.
Do not paste the list as a block of hidden or tiny text. It is easy to spot, and a person who finds it stops trusting everything around it.
Where the keywords hide
Some postings spread the useful words across sections you might skip:
- The title. Often the single most searchable phrase. If your last title was “Client Happiness Associate” and the posting says “Customer Support Specialist”, you can write your real title and add the standard one in brackets.
- The first bullet of responsibilities. Employers tend to list the main duty first.
- “About you” and “requirements”. Usually the densest source of tools and credentials.
- The “nice to have” list. Often the place the competition separates.
- Repeated verbs. If a posting says “own”, “drive” and “lead” in different bullets, the employer wants someone who takes responsibility. A bullet that begins with “Led” or “Owned” for something you truly led or owned answers that directly.
If you are comparing several postings for the same kind of role, put the must-haves side by side. The terms that show up in most of them are the ones to keep permanently on your base resume, and the rest can be added per application.
When doing it by hand is enough
You do not need a tool for this. Reading, underlining and sorting takes about ten minutes for a posting you care about, and doing it yourself has a real benefit: you notice what the job actually is, which helps in the interview too.
By hand is the right choice when:
- You are applying to a handful of roles a week and each one matters.
- The posting is short and clear.
- You are changing fields and need to think carefully about which of your skills transfer.
When a tool saves you the time
The slow part is rarely finding the keywords. It is the next step, rewriting six or seven bullets so they use the posting’s language without changing a single fact. Do that for fifteen applications in a week and it gets sloppy.
That is the part InstaResume is built for. You paste your real experience and the posting, and it writes resume bullets grounded in what you gave it, in the posting’s vocabulary. It does not invent employers, figures or tools you never mentioned. It does not score your resume against the posting, so the sorting in steps 2 to 5 stays with you.
As of October 2026, the free tool pages give 3 generations a day without an account. A free account adds 5 generations, granted once, which do not refill, plus PDF and DOCX export. Pro is $9 a month for 500 generations a month, and one-time credit packs are $2.50 for 100 credits or $10.00 for 500. A page like resume bullet points for customer service lets you try it with an optional job posting field before you sign up.

A quick checklist
Before you send an application, check that:
- You can state the job in one sentence.
- You underlined searchable nouns, not adjectives.
- Repeated terms are on your must-have list.
- Every keyword you use matches something you did.
- The posting’s job title, or a true equivalent, appears near the top.
- The skills section leads with the posting’s required tools.
- Nothing is in white text, tiny text or an image.
Frequently asked questions
How many keywords should I use?
Six to ten is typical for a one-page resume. More than that reads as a list and starts to crowd the evidence that you did the work.
Should I copy phrases word for word from the posting?
Use the posting’s wording for tools, titles and credentials, where an exact match is easiest to find. For everything else, say what you did in your own words, and keep it true.
What if the posting lists skills I do not have?
Leave them out. Apply anyway if you meet most of the must-haves. Postings describe an ideal candidate, and hiring managers usually expect some gaps.
Do I need to repeat this for every application?
Yes, but it gets faster. Keep a base resume with your permanent strengths, and spend your ten minutes on the three or four terms that differ from one posting to the next.
