ATS-friendly cover letter: what the software checks
An applicant tracking system is a database with a search box. It stores your letter, extracts its text and lets recruiters search and rank applications by the terms in the job ad. Then a human reads it. Your letter has to work for both.

A recruiter's view: Reads well: specific, with numbers, in plain sentences.
Notice that the keyword-stuffed version scores as well as, or better than, the tailored one, and any person would bin it. The tailored version wins because every matched term sits inside a sentence that proves it. That is the whole trick: match the words, and prove them. The same idea drives ahaboo, a free companion project whose explainers let you manipulate a model until the concept proves itself.
ATS-friendly formatting checklist
- Single column, left-aligned text. No tables, text boxes or columns.
- Contact details in the body of the page, not in the document header or footer.
- Standard fonts such as Calibri, Arial, Georgia or Cambria.
- No images, logos, icons or charts carrying information.
- PDF or .docx exactly as the posting asks. Avoid scanned images of letters.
- Test it: copy all the text into a plain text editor. If it reads in the right order, a parser can read it too.
ATS-friendly wording
- Use the exact job title from the posting at least once.
- Mirror the employer's terms. If they say "stakeholder management", do not only write "working with partners".
- Spell out acronyms once where both forms are common: "search engine optimisation (SEO)".
- Put each key skill in a proof sentence with a result, not in a list.
- Only claim what you have. The interview will test every keyword you use.
The AI cover letter generator does this for you: paste the job ad and it extracts the key terms, uses the ones your experience supports and highlights them in the finished letter. The checker shows which terms an existing letter covers.
Frequently asked questions
Do applicant tracking systems read cover letters?
Often, yes. Most ATS platforms store the cover letter with your application, and many let recruiters search all application text by keyword. Some also parse it. Either way, a person usually reads it next, so it has to work for both.
What makes a cover letter ATS-friendly?
A single-column layout with no tables, text boxes, headers, footers or images; a standard font; the exact job title; and the job ad's key skills written the way the employer wrote them. Submit a PDF or .docx as the posting asks.
Does keyword stuffing help pass the ATS?
No. Repeating keywords or hiding them in white text may raise a match score in a few systems, but recruiters see the text too and reject it. Use each important term naturally, in a sentence that proves you have the skill.
Is it true that ATS rejects 75% of résumés?
That figure is widely repeated but has no solid source. In practice most ATS software ranks and filters applications for a recruiter rather than silently deleting them. Matching the job ad still matters, because recruiters search and sort by those terms.
