As a Certified Professional Resume Writer, I spend a good part of my week deleting words from other people's resumes. Not because those words are wrong, but because they're doing no work. "Results-driven synergistic self-starter" occupies prime space at the top of the page and communicates absolutely nothing a hiring manager can verify or act on. Meanwhile the one keyword that would have cleared the applicant tracking system and caught the recruiter's eye — the actual name of the software the job requires — is missing entirely. Keywords matter enormously. But which keywords matter is where most people go wrong.

The useful mental model is that a resume carries three kinds of keywords, and they play by different rules: hard skills, soft skills, and action verbs. Get the balance right and your resume reads as concrete and credible. Get it wrong and it reads as a word cloud.

Hard skills: the keywords that gatekeep

Hard skills are the specific, teachable, provable capabilities a job requires — tools, technologies, methods, certifications, languages, and measurable proficiencies. These are the keywords that get you past automated screening and confirm to a human that you can actually do the work. They are not negotiable, and they are not paraphrasable.

Examples of true hard skills:

Name them exactly as the industry names them

Precision is everything here. "Microsoft Excel" and "advanced Excel (pivot tables, VLOOKUP, macros)" send very different signals, and a filter searching for "pivot tables" will only find the second. Spell out an acronym at least once alongside its short form — "Search Engine Optimization (SEO)" — because you don't know which version the posting or the screening tool uses. And only list what you can defend in an interview. A hard skill on your resume is a promise; if you write "SQL" you should expect to be asked to describe a query you've written.

Soft skills: real, but they can't stand alone

Soft skills are the interpersonal and self-management qualities that shape how you work: communication, collaboration, adaptability, leadership, problem-solving. They matter to employers — often more than candidates realize — but as bare keywords they are nearly worthless, because everyone claims them and no one can prove them in a bullet.

Here's the distinction I teach every client. Writing "excellent communication skills" is an assertion. Writing "presented quarterly forecasts to a 12-person executive team and translated technical findings for non-technical stakeholders" is evidence of communication skills. The second version never uses the word "communication," yet it proves it far more convincingly. Soft skills belong in your resume demonstrated, not declared.

There's one legitimate exception: if the job posting itself explicitly names a soft skill as a requirement — say, "strong written communication is essential" — then including that phrase once helps you match, because a screener may be looking for it. Even then, back it with a demonstrated bullet somewhere on the page. Match the word, but earn it.

Action verbs: the engine of every bullet

If hard skills are what you know and soft skills are how you work, action verbs are what you did. They are the first word of nearly every bullet point, and they set the entire tone. Weak, passive openers drain your accomplishments of force. Compare "Responsible for managing the social calendar" with "Built and managed a 3-platform content calendar that grew engagement 60%." Same underlying fact; completely different candidate.

Trade tired verbs for precise ones

The problem isn't just passive phrasing — it's overused, low-information verbs. "Managed," "led," and "handled" show up on every resume in the pile. They're not wrong, but a sharper verb tells the reader more about the kind of contribution you made:

Two rules keep this from backfiring. First, use past tense for past roles and present tense only for your current one — mixing them mid-resume reads as careless. Second, don't reach for a thesaurus word you wouldn't say in conversation. "Spearheaded" is fine; "actualized" makes a hiring manager wince. The verb should be strong and natural.

The pattern that ties it together

The best resume bullets braid all three keyword types into a single line: an action verb, a hard skill, and an implied soft skill proven by the result. "Automated (verb) monthly reporting in SQL and Excel (hard skills), cutting a two-day manual process to under an hour (result — proving efficiency and problem-solving without naming them)." That one sentence clears the ATS on the tools, satisfies the human on the impact, and demonstrates a soft skill you never had to claim.

The practical takeaway

Audit your resume with three colored highlighters — one for hard skills, one for demonstrated soft skills, one for action verbs. If you're short on hard-skill keywords, you'll get filtered out before a person reads a word, so pull the missing ones straight from the job posting (only the ones you honestly have). If your soft skills are asserted instead of demonstrated, rewrite them as accomplishments. And if your bullets open with "responsible for" or a tired "managed," swap in a precise action verb and add the number that proves it. Keywords aren't about cramming the page — they're about making every word earn its place.
