The 4 traits of a good resume
After reviewing thousands of resumes, the pattern is clear. Good resumes aren't about fancy design — they're about how well you communicate your impact.
Achievements, not duties
Good resumes show what you accomplished. Bad resumes list what you were supposed to do. The difference is everything.
Numbers everywhere
Revenue, percentages, time saved, team size, users impacted. Numbers make your claims concrete and credible.
Every line is relevant
No filler. No "detail-oriented team player." Every bullet directly supports why you're right for this job.
Tailored to the role
Good resumes mirror the job description's language. They're customized for each application, not sent blindly.
Before and after: weak vs. strong resume bullets
The fastest way to improve your resume is to rewrite your bullets. Here's what that looks like in practice.
Marketing Manager
Before
"Helped with marketing campaigns and managed social media accounts."
After
"Launched 12 email campaigns that increased sign-ups by 25% and generated $120K in pipeline within 6 months."
Software Engineer
Before
"Worked on backend services and fixed bugs."
After
"Redesigned API layer serving 2M+ requests/day, reducing p95 latency by 60% and eliminating 3 recurring production incidents."
Project Manager
Before
"Responsible for managing a team of developers and meeting deadlines."
After
"Led cross-functional team of 8, delivering 3 features ahead of schedule and reducing deployment time by 40%."
Sales Representative
Before
"Sold products to customers and maintained relationships."
After
"Exceeded quarterly quota by 130% ($480K), closing 35 new accounts and growing existing revenue by 22% YoY."
The Action + Scope + Result formula
Every strong resume bullet follows the same formula. Once you learn it, your entire resume gets better immediately.
Action
What you did. Start with a strong verb: Led, Built, Launched, Reduced, Increased, Designed.
Scope
At what scale. Team size, number of users, budget, geographic reach, number of projects.
Result
The measurable outcome. Percentage improvement, revenue generated, time saved, cost reduced.
How to evaluate your own resume
- Read each bullet — does it describe a duty or an achievement?
- Count the numbers — do at least half your bullets include a metric?
- Check the relevance — does every line support the job you're applying for?
- Look for filler — "team player," "detail-oriented," "hard worker" add nothing. Cut them.
- Run it through JobScoutly's Job Match Analyzer — get an objective match score against a real job description.
FAQ
What's the biggest mistake on most resumes?
Listing responsibilities instead of achievements. 'Managed a team' tells the recruiter nothing. 'Led a team of 8 that shipped 3 features ahead of schedule, reducing deployment time by 40%' tells them everything.
How do I add numbers to my resume if my job didn't have metrics?
Every job has numbers. Think about: how many people you worked with, how many tasks you handled per week, how much time you saved, how many customers you served, or what percentage improvement you contributed to.
How do I know if my resume is good enough?
Use JobScoutly's Job Match Analyzer to compare your resume against a real job description. It shows your match score, missing keywords, and specific improvements — giving you an objective assessment.
Should my resume be one page or two?
One page for most professionals. Two pages only if every line is directly relevant to the job. A tight one-page resume with strong bullets beats a padded two-page resume every time.
What's the fastest way to improve a weak resume?
Rewrite your experience bullets using the Action + Scope + Result formula, and add numbers wherever possible. This single change has the biggest impact on resume quality.
