ATS resume checker guide: how to read the result and what to do next
A resume checker is only useful if you can act on what it tells you. This section explains what each part of the report means, why a resume can be hard for software to parse, and how to turn a flagged item into a better document.
What an ATS resume scanner checks
This scanner works on the text layer of your file — the characters a parser reads — rather than on how the page looks. It looks for the four standard section headings, contact details written as plain text, measurable outcomes in your bullets, strong action verbs, consistent date formats, common misspellings and unusual characters. It also compares your text against a fixed list of skills and tools, and quotes back the results it found so you can check them yourself.
What it does not do is reproduce any employer's system. Each ATS is configured by the company running it — what it extracts, which fields it keeps, how it ranks candidates and whether a person reads the file are all settings this tool cannot see.
Why a resume can be difficult to parse
Parsing problems are almost never about the quality of the writing. They are about where the words live and how the document is built:
- Text inside images. A scanned page, a logo with your name in it or a heading saved as a graphic has no text layer at all. Nothing can extract it — not this tool, and not an employer's system.
- Headings that are worded unusually. “Where I've Worked” reads well to a person. A parser looking for a section boundary expects “Work Experience” or an obvious equivalent, so an unusual heading can hide a whole section from automatic reading.
- Multi-column layouts. Two columns are read in the order the text objects were written, which is not always the order you see. A sidebar's content can end up spliced into the middle of a job description.
- Headers and footers. Some exports put running headers, page numbers and even contact details outside the main text flow, where they can be dropped or repeated on every page.
- Tables and text boxes. Content in a table cell or a floating text box is often extracted without the order or the labels that made sense visually.
How to read your score
The score starts at 100 and each flagged rule removes a fixed number of points, weighted by how much that property tends to cost a reader. The report shows every deduction and the section it came from, so you can add the column up and get the score back. A thin document — a few lines pasted in — is labelled as thin instead of being scored as if it were a resume.
Read the score as a consistency check: does this document still carry the structure, the contact details and the evidence a reader needs? Then read the two or three highest-cost findings and act on those. A high score is not an interview and a low one is not a rejection; both are statements about eight checks on one file.
How to improve formatting and keywords
Formatting first, because it decides whether your content can be read at all: one column, standard headings, plain-text contact details in the body of the first page, a single date format, and bullets that begin with the action you took. Then the content: give at least three bullets a number — scale, size or change — and replace filler phrases with the specific thing you did.
Keywords come last, and they come from the advert rather than from a list. Read the job description, note the tools, methods and responsibilities it names, and make sure the terms that genuinely describe your work appear in your resume in your own words. A keyword you cannot back up in an interview costs more than one you never added. To compare your resume against one specific advert, use the job match score; it measures the overlap between your resume and that posting.
Fix the resume, then scan the exported file
The report is a to-do list, not a diagnosis. Make the edits in whatever you wrote the resume in, export the final file, and scan that exact file — the checks run on text, so what matters is what the exported document actually contains, not what your editor showed you. If you would rather start from a layout that is already structured for parsers, the free ATS-friendly resume templates use standard headings, one reading column and selectable text, and the resume builder exports the same content as a print-ready PDF or a Word file.
