"Improved" shows up on almost every resume, and that is exactly the problem. It tells a recruiter that something got better, but not in which direction, by how much, or how you did it.
"Improved the onboarding process" could mean you shaved off an hour or an entire week, and the reader has no way to tell. On its own the word is a placeholder for a result you have not stated yet.
The fix is not to swap in a fancier verb and stop there. It is to name the specific kind of change you drove, whether you sped something up, cut waste out of it, made it stronger, or lifted a number, and then attach the before and after figure that proves it.
This page gives you stronger, recruiter-tested alternatives for "improved," each with a short note on when it fits, plus before and after bullet examples so you can see the swap in context. Use the verb that is literally true for what you changed, then let a concrete number carry the weight.
A precise verb with no figure is still weak, and a figure with a vague verb is still forgettable. You want both.
Pick the verb that matches what you actually did, then back it with a number. A precise verb plus a result beats any thesaurus swap on its own.
What can I say instead of "improved" on a resume?
Match the verb to the change you made. Use "streamlined" or "optimized" for processes, "boosted" or "increased" for metrics you grew, "accelerated" for speed, and "strengthened" for reliability. Pick the one that is literally true, then add the before and after number.
Is "improved" a bad word for a resume?
It is not wrong, just vague and overused. It says something got better without saying which way or by how much. Keep it in one spot where it genuinely fits, and replace the rest with a specific verb plus a figure.
How do I show an improvement without the word "improved"?
State the metric and the change. "Cut onboarding from 5 days to 8 hours" proves an improvement better than "improved onboarding" ever could. The number and the direction do the work, so lead with the result.
Do I need a number every time I describe an improvement?
Aim for one on every result bullet. A percentage, a time saved, a dollar amount, or a before and after count turns a claim into evidence. When you truly cannot measure it, describe the concrete outcome instead, but a real figure is always stronger.
Do synonyms for "improved" help with ATS?
Applicant tracking systems match the keywords in the job posting, so mirror the exact verbs the description uses. Synonyms mostly help the human reader. Use the posting's language where it fits and vary your verbs everywhere else so no bullet repeats.
