To optimize a resume for ATS: (1) scan it for a baseline, (2) fix the format so every line parses (single column, standard headings, no text in images or tables), (3) match the posting by using its terms for skills you have, (4) rewrite duty bullets as results, and (5) rescan and save a version per job. Steps 1–4 are free; only the format fix has to be done once.

Step 1: scan your resume
Start with a baseline so you can tell whether your edits help. The scanner at the top reads your file as plain text and scores five areas — ATS compatibility, content quality, achievements and impact, keywords, and presentation — then lists the three fixes that matter most. Prefer a manual check? Do the copy-paste test in the ATS-friendly resume guide.
Step 2: fix the format once
Avoid: Move contact details out of the page header
Avoid: Replace skill bars, icons and images with words
Be careful: Collapse columns and tables into one column
Do: Rename creative headings
Do: Use one date format for every job
Background on why these break: how an ATS reads your resume. Starting over is sometimes faster — the ATS-friendly templates page compares layouts.
Step 3: match the job posting
Recruiters search the ATS for the job's own terms. Read the title, the requirements and anything repeated; for each term, check whether your resume says it in the same words. The full method, with a worked example, is in ATS keywords: how to find and use them. Doing this for many applications? Our tailoring tool (Pro) rewrites your resume to one job description and saves it as a separate version, without inventing experience.
Step 4: rewrite bullets as results
This step is for the human who opens your resume after the ATS: a bullet that says what changed because of you beats one that lists a duty. It also raises the content and impact parts of the score.
Helped with planning trade show events.
Planned booth logistics for 3 regional trade shows, coordinating 4 vendors and staying within a $25K budget.
Worked on the email newsletter every month.
Wrote and sent the monthly customer newsletter to 18,000 subscribers; open rate rose from 21% to 27% over six issues.
Stuck on a verb? The bullet point generator rewrites one bullet three ways for free, and resume synonyms replaces “responsible for” and friends.
Step 5: rescan and keep a version per job
Scan again. AI scoring moves a few points between runs, so a change of more than about 3 points means your edits did something. Keep your master resume clean and save a tailored copy per application so you always know what each employer received. What a score means, and what “good” is: ATS score explained.

Frequently asked questions
How do I optimize my resume for ATS?
Scan it to get a baseline, fix anything that stops the text from parsing (columns, tables, text in images, contact details in the header), use the job description's terms for skills you really have, rewrite duty bullets as results, then rescan and keep a separate version for each job you tailor to.
Do I need to optimize my resume for every job?
The format only needs fixing once. The wording is worth adjusting for each job you care about, because recruiters search for that posting's terms. Many people keep one master resume and save a tailored copy per application.
Can I optimize my resume for ATS for free?
Yes. Every step can be done by hand, and the scanner on this page is free with no account. A free account adds the full score breakdown and the builder. What costs money with us is downloading the finished file, the tailoring tool and cover letters (Pro).
Is it cheating to optimize a resume for ATS?
No, as long as everything stays true. Using the posting's words for things you actually did helps the recruiter find you. Inventing skills, pasting the job description or hiding keywords in white text is what crosses the line — and recruiters can see all of it in the parsed text.
