Everything you need to know about ATS, optimizing your resume, and keeping your data private.
An ATS (Applicant Tracking System) is recruiting software that companies use to automate the intake, filtering and ranking of applications before any human review. According to a 2024 Jobscan study, over 98% of Fortune 500 companies use an ATS to screen applications. An ATS-optimized resume uses a single-column layout, a native file format (.docx or digital PDF), and includes the exact keywords from the job postings you target. Without that optimization, a resume can be rejected automatically — even if the profile is a perfect fit.
In short :an ATS-optimized resume is structured, machine-readable by recruiting software, and contains the right keywords so it isn't filtered out before a human sees it.
ATS reliably read .docx files and digitally generated PDFs — that is, PDFs exported from software, not scanned. Scanned PDFs, .jpg/.png images and Apple .pages files are often misread or ignored entirely. CVReader handles the two main safe formats and tells you if your file will cause issues before you ever send it to a recruiter.
In short :use a .docx or a digitally exported PDF — never a scan or an image.
No. Most ATS cannot correctly interpret complex layouts: multiple columns, tables, floating text boxes, graphic callouts or infographics. Content is often extracted in the wrong order — or lost entirely. A single-column layout with standard section headings (Experience, Education, Skills) is consistently parsed better. CVReader checks the structure of your resume automatically and flags anything likely to break automated extraction.
In short :an ATS-friendly resume must be single-column, with no tables or graphic boxes.
It's one of the most common issues: a visually polished resume can still score very low against ATS. The usual causes are formatting that's illegible to parsers (columns, images, non-standard fonts), missing keywords for the targeted roles, section structures unrecognized by ATS, or key information placed where parsers don't look. CVReader evaluates your resume against 25 technical criteria and identifies exactly what's blocking you, with concrete next steps.
In short :a beautiful resume isn't necessarily an ATS-readable one — CVReader tells the two apart.
There's no certain way to know after the fact. Some signals, however, suggest automated filtering: complete silence even when your profile matches, rejections sent minutes after submission, or systematic rejections on certain platforms. The best approach is preventive: check your resume before you apply to make sure it passes the ATS screen. CVReader gives you an ATS compatibility score before your document is ever submitted to recruiting software.
In short :prevent automated filtering by checking your resume on CVReader before you apply.
It depends on the issues detected. If your resume has deep structural problems — multi-column layouts, tables, text boxes, non-standard fonts — a full rebuild is usually more effective than partial fixes. If the format is clean but keywords or content are lacking, targeted optimization is enough. CVReader recommends one of the two approaches in your report, with a prioritized action plan.
In short :CVReader tells you exactly whether rebuilding or optimizing is the better investment for your situation.
Yes, as long as the format is right. Modern ATS support Latin-alphabet languages. Badly encoded special characters, exotic fonts, or complex layouts remain sources of errors regardless of language. CVReader checks for encoding and readability issues specific to each supported language.
In short :language isn't the problem for modern ATS — the file format is.
The keywords to include are those found in the job postings you target: technical skills, tools, certifications, exact job titles. ATS compare your document word-for-word with the job description — a skill phrased differently from the posting's wording may not be recognized. CVReader identifies missing terms based on your industry's standards and suggests how to add them naturally.
In short :use the exact wording from the jobs you target — CVReader tells you which terms are missing.
Your resume title should match the exact job title as it appears in the posting. Creative phrasings like "Versatile professional" or "Opportunity hunter" are neither recognized by ATS nor valued by human recruiters. A precise title like "Full Stack JavaScript Developer" or "Digital Marketing Manager" consistently performs better because it matches both the recruiter's search and the ATS scoring.
In short :your resume title should match the job title word-for-word — don't get creative here.
Practices vary by country. From an ATS perspective, a photo can cause problems: some parsers confuse it with text content and corrupt extraction of nearby data. For online applications going through platforms or ATS, it's safer to omit the photo or place it in a neutral area. For applications handed directly to a human recruiter, it remains a common practice in some markets.
In short :remove the photo for online applications; keep it only for direct applications where expected.
For junior to mid-level profiles (less than 10 years of experience), one page is recommended. Beyond 10 years, two pages are acceptable. ATS don't penalize length — it's the human recruiter who rarely reads past page two. The golden rule: every line must earn its place. A dense one-pager beats a diluted two-pager.
In short :one page up to 10 years of experience, two pages maximum beyond — every line must earn its place.

In short :without an account, you get the global ATS score, extracted data, and a strengths overview.
The free account (Discovery plan) gives you access to the 24 detailed ATS criteria and your CV history. Credits for AI parsing, CV/job matching, and optimized CV generation are available through paid plans or credit packs.
In short :the Discovery plan unlocks detailed ATS criteria and CV history.
CVReader analyzes your resume against 25 technical criteria used by professional ATS and produces a detailed report with prioritized recommendations. You know exactly what to fix, in what order, and why. The built-in resume builder then guides you step by step to produce a document that's natively ATS-compatible — without having to master the rules yourself.
In short :CVReader turns a resume rejected by ATS into one that reaches human recruiters.
The analyzer evaluates your existing document, identifies weaknesses and gives you an action plan. The builder lets you start from a clean, structured, natively ATS-compatible base — useful when structural issues are too deep to fix with partial edits. Both tools are available on CVReader and can be used together: analyze first to diagnose, rebuild if a full redo is recommended.
In short :the analyzer diagnoses, the builder rebuilds — CVReader offers both, depending on your situation.
CVReader is designed with GDPR compliance in mind. If no email is detected in your resume, your data is automatically deleted within 24 hours.

In short :CVReader automatically deletes your data within 24 to 90 days depending on your situation — with immediate deletion available on request.
Nobody. Your document is processed in a fully automated way to generate your analysis report. No recruiter, no business partner, no third party has access to it. CVReader is a technical analysis tool — not a matchmaking platform and not a candidate database for employers. Your resume stays strictly between you and the analysis software.
In short :CVReader doesn't share your resume with anyone — it's a private analysis tool, not a candidate database.
