Which parts of a resume should change for each job?
The top third of the page does most of the work. Rewrite the headline and summary for the role, move your most relevant bullets to the top of each job, and reorder the skills list so the posting's must-haves come first. Contact details, dates, employers and the layout stay exactly as they are.
| Part of the resume | Change it? | How |
|---|---|---|
| Headline | Yes | Use the posting's job title if it matches what you do. "Customer Success Manager" beats "Client Relationship Professional" when that is the title on the ad. |
| Summary | Yes | Two or three sentences that answer the first requirements of the posting with your own evidence. |
| Experience bullets | Reorder and reword | Put the most relevant bullet first in each role. Swap generic verbs for the posting's terms when they are accurate. |
| Skills | Reorder | List the required tools first. Remove filler skills the job does not ask for. |
| Employers, titles, dates | Never | These are facts a background check can confirm. They stay identical in every version. |
| Layout and template | No | One clean, single-column layout for every version keeps the parsed text predictable. |
How do you pick the right keywords from a job description?
Separate the requirements from the background noise. Hard skills, named tools, certifications and the job title matter most; phrases like "fast learner" or "team player" matter least. A term that appears in the title, the requirements list and the duties is almost always one a recruiter will search for.
Here is a short extract from a sample posting for a Customer Success Manager, and what to take from it:
Posting
You will own renewals for a book of mid-market SaaS accounts, run quarterly business reviews (QBRs), and track account health in Gainsight. Experience with Salesforce and a reduction in churn are a plus. Strong communicator.
Terms worth matching
renewals, mid-market, SaaS, quarterly business reviews (QBRs), Gainsight, account health, Salesforce, churn
"Strong communicator" is left out on purpose: every posting says it, and a bullet that shows you presenting a QBR proves it better than the phrase.
Write both forms of an abbreviation once ("quarterly business reviews (QBRs)"), because a recruiter may search either one. Paste the posting and your resume into the free job description keyword matcher to see which terms your resume already covers. The guide to finding resume keywords has more examples by field.
What is a step-by-step way to tailor a resume?
Start from a complete master version, never from the last tailored copy, or old edits pile up. Then work through the posting in a fixed order: terms, summary, bullets, skills, a final read. Most people get faster with practice; the first tailored version takes the longest because you are building reusable bullets.
Save a copy of your base resume
Name it after the company and role, for example "Resume - Acme - Customer Success Manager". Your base stays untouched.
Mark the posting's terms
Highlight the job title, required tools, certifications and the first three duties. Ignore soft-skill adjectives.
Rewrite the summary
Answer the first two requirements with your own numbers or scope. Use the posting's job title if it fits.
Reorder and reword bullets
In each role, move the most relevant bullet to the top. Replace vague wording with the posting's term where it is accurate.
Adjust the skills list
Required tools first, in the posting's spelling ("Salesforce", not "SFDC" alone).
Check the result
Read it as the recruiter would, then run it through the free resume checker to catch formatting problems before you send it.
What does a tailored bullet look like next to the original?
A tailored bullet says the same true thing in the employer's words and adds the scope the posting cares about. It does not add a tool you never used. In the example below, the candidate really ran reviews in Gainsight; the original bullet simply did not say so.
Original bullet
Managed a portfolio of customer accounts and answered their questions.
Tailored for the Customer Success Manager posting
Owned renewals for 40 mid-market SaaS accounts and ran quarterly business reviews (QBRs) from Gainsight health scores.
The number and the tool are only allowed because they are true for this candidate. If you never used Gainsight, leave it out and mention the tool you did use.
How far can you stretch a resume to match a job?
Reword freely, invent nothing. You can rename "helped customers" as "customer onboarding" if that is what it was. You cannot add a certification, a tool, a title or a result you do not have. Anything on the page can come up in an interview, and a reference call can contradict it.
If the posting asks for something you lack, say so where it helps you: a cover letter line about a related tool you learned quickly is honest and often enough. Our guide on tailoring a resume to a job description covers gaps in more detail.
How does Ruubu help you tailor a resume?
Paste a job link into the free Job Link Optimizer to see your match and the missing terms. With Pro, Tailor writes a separate copy of your resume for that posting and shows every change. A guard puts your original employers, titles and dates back and removes any number your resume did not contain.
- Free: the Job Link Optimizer, the keyword matcher and the resume checker with 14 checks.
- Pro: resume tailoring per posting. Your base resume is never changed; the tailored copy is a new version you review before export.
- A skill the posting asks for but your resume does not show is listed as a gap, not added to your skills.
Every score on Ruubu measures your own resume: how cleanly it reads and how much of the posting it covers. Those are the parts you control before you apply.
Frequently asked questions
Do I need a different resume for every job?
For jobs you care about, yes, but it is a light edit: summary, bullet order and skills. Jobs with the same title at similar companies can often share one tailored version.
How many keywords from the job description should I use?
There is no reliable number. Use every required term that truthfully describes your work, once or twice in context, and stop there. A list of keywords with no evidence reads badly to the person who opens the file.
Should I copy sentences from the job description?
Copy terms, not sentences. A bullet that repeats the posting word for word reads as pasted and says nothing about what you did.
Is it fine to change my job title to match the posting?
Only in the headline, and only if it describes your work. Keep the official title in the experience section; a background check will compare it with your employer's records.
Can I use ChatGPT to tailor my resume?
Yes, as long as you check every line it returns. General chatbots tend to add metrics and tools that sound right. Give it your facts first and tell it not to add numbers.
Does tailoring matter if I apply through LinkedIn Easy Apply?
Yes. Easy Apply sends your resume to the employer, where a recruiter reads or searches it like any other application.
