What Is Resume Keyword Matching?
Resume keyword matching compares the important skills, tools, certifications, and other relevant terms a job description asks for against what actually appears in your resume. Rezup extracts the required and preferred skills from a job posting, then checks your resume text against that list to show where your coverage is strong and where relevant gaps remain.
Some applicant tracking and recruiting workflows use keyword and skills matching as part of candidate screening, but ATS configurations vary widely from company to company. Rezup's keyword matcher gives you a clear, actionable picture of your resume-to-job overlap - not a prediction of how any specific employer will respond.

What you get from every keyword match check
A clear picture of how well your resume covers the skills and keywords this job asks for.
Match score
An overall keyword match percentage plus a required-skills coverage number - the one to watch most closely.
Matched & missing keywords
Every keyword tagged Required or Preferred, split into what your resume already covers and what it's missing.
Required-skill gaps flagged
A clear callout when your coverage of must-have skills is low - usually the fastest place to strengthen a weak application.
Sections to fix
Actionable suggestions on where to add or strengthen keywords - not just a list, but where in your resume it matters.
Section-weighted, not just present/absent
A keyword in your job title or a recent bullet counts far more than the same word buried in a hobbies list.

Not every keyword match counts the same
A simple “does this word appear anywhere in the resume” check misses something that matters: where the word appears. A skill mentioned in your job title or in a bullet point from your most recent role reads as real, demonstrated experience. The same skill dropped once into a crowded skills list, or buried in an interests section, reads as much weaker evidence.
Rezup uses a rule-based scoring model that considers both keyword coverage and where relevant terms appear in your resume: keywords in your title and recent experience bullets count the most, skills-list mentions count less, and hobbies or interests essentially don't count. This is Rezup's own matching methodology and shouldn't be treated as a universal representation of every ATS - some applicant tracking and recruiting workflows use keyword and skills matching as part of candidate screening, but configurations vary widely between companies. That's also why the fix suggestions below your results often point you toward moving a keyword into a bullet point rather than just adding it to a list - the same word in a stronger section usually raises your score more than adding a new one.

Frequently asked questions
What is resume keyword matching?
It's a comparison of the important skills, tools, certifications, and other relevant terms a job description asks for against what actually appears in your resume. Rezup compares a job description with your resume and shows where your resume has strong coverage and where relevant gaps may exist.
Is Rezup's keyword matcher free?
Yes. Paste a job description and your resume text and get your match score, matched keywords, missing keywords, and fix suggestions - no account, no credit card required. It's free to use with no signup, though anonymous use is subject to a shared daily limit that keeps the tool available during high demand.
How is the match score calculated?
The score is rule-based, not AI-guessed: Rezup compares the required and preferred skills extracted from the job description against the actual text of your resume, weighted by where each keyword appears - your job title and recent experience count more than a skills list, which counts more than a hobbies section. This is Rezup's own matching methodology, the same deterministic scorer that powers Rezup's ATS Checker, and it shouldn't be treated as a universal representation of every ATS.
What does "Required" vs. "Preferred" mean on a keyword?
Required keywords come from skills the job description treats as non-negotiable for the role. Preferred keywords come from its "nice to have" list. A low match rate on required keywords is usually the more urgent gap to close - that's typically the best place to focus your resume updates first.
Should I add every missing keyword to my resume?
No - only add ones that are actually true of your experience. Stuffing keywords you can't back up in an interview does more harm than good. Prioritize missing required keywords you genuinely have experience with first, and work them into real bullet points rather than a buried list, since where a keyword appears affects how much it counts.
