Advice about applicant tracking systems (ATS) is full of myths, from "your resume is rejected by a robot" to "use white text keywords". The truth is plainer and more useful: an ATS is mostly a database that reads your resume, stores it and lets a person search it. Making that easy is a matter of clear structure and honest keywords.
What an ATS actually does
An ATS collects applications, extracts the text and stores it in fields: name, contact details, work history, education, skills. Recruiters then search and filter. Some systems rank or score candidates, but a person usually makes the decision. The practical consequences are simple:
- If the system cannot read your file properly, your details may be stored wrongly or not found.
- If your resume does not contain the terms a recruiter searches for, it will rank lower, however good you are.
What the Resume ATS Checker scores
The Resume ATS Checker reads the text of your resume, uploaded as a PDF, DOCX or TXT file or pasted, and gives points in five areas:
| Area | Points | What it looks for |
|---|---|---|
| Contact information | 7 | An email address, a phone number and a professional link such as LinkedIn or GitHub |
| Format and structure | 7 | At least three standard sections (such as experience, education, skills, summary), enough content and enough lines |
| Keywords and skills | 6 | Several relevant skill terms, and words that show proficiency |
| Action verbs and impact | 7 | Strong verbs such as led, built and improved, and numbers that quantify results |
| ATS compatibility | 7 | A word count of roughly 200 to 800, no decorative symbols or emoji, and no tab characters |
If you paste a job posting, a sixth area is added: a job description match, worth up to 10 points. The tool picks out the terms the posting stresses and shows which your resume contains and which are missing.
What it cannot tell you
It reads text only. It cannot see layout, fonts, columns, tables or images, so it cannot tell you whether your design will confuse a particular system. Its built-in list of skill keywords leans towards technology, business and marketing, so a resume in another field may score low on keywords even when it is strong; the job-description match is more relevant for those. A high score does not mean an interview.
A checklist that helps
- Use a simple layout. One column, standard headings (Experience, Education, Skills), plain bullets. Avoid text in headers, footers, text boxes and images.
- Choose a safe file. A DOCX or a PDF with real text works for most systems. A scanned PDF has no text at all.
- Put contact details in the body. Include an email, a phone number in any normal format, and a link to a profile or portfolio.
- Mirror the posting's wording honestly. If the job says "stakeholder management" and you did that, use those words.
- Start bullets with verbs and include numbers: "reduced processing time by 30%".
- Keep it to a sensible length. Two pages is common for experienced applicants.
- Avoid decorative symbols, emoji and unusual characters.
- Do not stuff keywords. Hidden or repeated terms can hurt you when a person reads it.
Check the text itself
Before you submit, run the writing through the Grammar and Spelling Checker and count the words with the Word Counter. A typo in a job title can cost a keyword match. If your resume is a PDF, make sure it has selectable text; if you build it from a Word file, Word to PDF produces a searchable PDF.
Your file stays private
Your resume is read in your browser. It is not uploaded, which matters because it contains personal details. Remove sensitive information you do not need to share, such as a full home address, before you apply anywhere.
