An applicant tracking system, or ATS, is the software many employers use to collect applications. It reads your file, pulls out the text, and lets a recruiter search and filter. A resume can have strong experience and still do badly if the software scrambles it, or if a recruiter skimming it cannot find the proof in a few seconds.
That gives you two readers with different needs. The software needs a plain, predictable file. The person needs bullets that show what you did and what changed because of it. This guide covers both: how to format for the software, and how to write each bullet using SMART, which stands for specific, measurable, achievable, relevant and time-bound.
One caution first. ATS products differ, and nobody can promise that a resume will pass any particular one. What follows is the advice that university career centers and hiring organizations broadly agree on, and none of it asks you to claim anything untrue.
1. Start with a file the software can read
Format comes first, because a resume that cannot be parsed cannot be judged. Keep it plain:
- One column. No tables, text boxes, multiple columns, icons, photos, charts or shading. Parsers can drop or scramble whatever sits inside them.
- A common font such as Arial, Calibri or Times New Roman, at 10 point or larger.
- Standard headings: Summary, Skills, Work Experience, Education, Certifications. A clever heading may not be recognized.
- Contact details in the body of the page, not in the header or footer, which some systems skip.
- Plain punctuation and one date format throughout, such as May 2021 to Present.
- The file type the application asks for. If it does not say, a .docx or a text-based PDF exported from a word processor is usually accepted. Avoid scanned or image-only PDFs.
Then test it. Save a copy as plain text and open it. If every word is there, in order, with the headings intact, the software will probably read it the same way. If anything is missing or jumbled, fix the layout before you apply.
2. Use the posting's words where they count
Searches often match exact wording, so "project management" and "managed projects" may not count as the same thing. Read the posting, note the terms it repeats, and use its phrasing for work you really did.
Put the job title near the top. A headline such as "Business Analyst | 6 Years in Retail Operations and Reporting" tells both the software and the recruiter what you are applying for. Use the title as the posting writes it, and only when your experience supports it. Follow it with a two or three sentence summary of your most relevant work.
Use each important keyword once to three times across the resume, inside real bullets, not stacked in a list. Spell out an acronym the first time with the short form in brackets, for example search engine optimization (SEO), so a search for either one finds you. If the posting asks for a skill you do not have, leave it out. You can address it honestly in the cover letter.
3. Write every bullet to be SMART
SMART is usually a goal-setting method. It works just as well as a test for resume bullets, because each letter closes a gap that vague bullets leave open:
- Specific: say what you did and with what. "Managed social media" becomes "Planned a weekly Instagram content calendar and tested three post formats."
- Measurable: add a number you can defend, such as followers, hours saved, volume or dollars. If you have no number, describe the scope: how many people, how much volume, how long the project ran.
- Achievable: keep the claim credible for your role. It should be something you could explain in an interview, and something your position could actually influence.
- Relevant: lead with the bullets that match this posting, in its language where that is honestly true. Cut what does not help for this role.
- Time-bound: anchor the result to a period, such as in 12 months, over two quarters or by month end. A timeframe shows pace and scale.
Here is the difference in practice. A weak bullet: "Responsible for managing social media accounts." A SMART one: "Grew Instagram followers from 2,100 to 9,800 in 12 months by planning a weekly content calendar and testing post formats." The numbers in that example are invented for illustration. Use your own, and never use one you cannot back up.
4. Start with a verb, end with a result
A reliable pattern for a bullet is an action verb, what you did, the result, and the timeframe. Verbs like led, built, reduced, launched and trained show your part in the work. Phrases like "responsible for," "helped with" and "worked on" describe duties and hide what you personally did.
Cut words that carry no detail, such as various, multiple, several and etc. Drop self-praise like "dynamic" or "results-driven" unless a specific example backs it up. A recruiter cannot check an adjective, but they can check a number.
If you know the result but not the figure, write a marked gap in your draft, for example reducing picking errors by [X%], and find the real number before you send it. Do not estimate.
5. Tailor it to each posting
Keep one master resume with everything you have done, then build a version for each application. Take each required term in the posting and check it against your history: do you have clear evidence, partial evidence, or none? Use the first, confirm the second, and leave out the third.
Reorder your skills and the bullets under each job so the most relevant come first. Put the education or certifications section higher if the role stresses them. Keep it to one page if you are early in your career and up to two pages if you have more experience, and trim older roles that do not relate to the job.
6. Check it before you send it
Run through this list for every application:
- The headline uses the target job title, and your summary connects to the role.
- Each priority keyword is used or left out on purpose, and none appears more than a few times.
- Each bullet starts with a verb and, where you can, includes a specific detail, a number and a timeframe.
- Nothing is invented: no metrics, tools, titles or dates you cannot support.
- The plain text copy has all the text, in order, with the headings intact.
- Spelling, dates and tense are consistent: past tense for previous roles and present tense for your current one.
- The file is named with your full name, the job title and the word Resume, for example Jane Doe, Marketing Coordinator, Resume.
The first resume you build this way will take a while. After a few, you will know your own history well enough that tailoring becomes a short edit and not a rewrite.
