The 12-point ATS compliance checklist
Grouped by the three pillars that move the score the fastest. Each rule shows the average point gain from our audit of 1,000 real resumes. Full numbers in the 1,000 rejected resumes study.
Pillar · Layout and file compliance
01 Use a single-column reverse chronological layout
+25 ptsTwo-column sidebar layouts scramble in Workday, Taleo, and iCIMS. Switching to single column raised the median parser score by 25.3 points in our 1,000-resume audit.
02 Export as a text-based PDF or DOCX, never a scanned image
+42 ptsImage-only PDFs score 0 against every parser because no text layer exists. Export directly from Word, Google Docs, or LaTeX.
03 Keep critical content outside headers and footers
+11 ptsPhone, email, and LinkedIn URL inside Word header or footer regions get skipped by Taleo and legacy Workday 28.4% of the time.
04 Replace Word tables with left-aligned text and tab stops
+8 ptsTable cells break job titles off from dates in 11.9% of DOCX resumes. Use plain text with tab stops instead.
Pillar · Keyword and acronym placement
05 Pair every acronym with its spelled-out form once
+19%Writing Google Analytics 4 (GA4) or Sarbanes-Oxley Act (SOX) raises the Taleo and iCIMS match by 19.4%, because both forms index as separate tokens.
06 Place each critical skill in both Skills and Experience
+8 ptsWorkday weights an Experience bullet 1.4 times higher than a Skills chip. Dual placement raised the Workday score by 7.8 points on average.
07 Target 72% to 84% hard-skill coverage against the posting
+15 ptsBelow 72%, you miss too many required tokens. Above 92%, Greenhouse and Lever down-rank for density stuffing.
08 Mirror the exact job title from the posting on your most recent role
+7 ptsTaleo weights exact title matches at 0.84. Writing Data Engineer when the posting says Senior Data Engineer costs 5 to 9 points.
Pillar · Experience and date formatting
09 Use MMM YYYY dates on every role, consistently
+4 ptsWorkday and iCIMS normalize to MMM YYYY. Mixed or non-standard dates cost an average of 4.1 points.
10 Quantify every bullet with a number, percent, or named project
+11 ptsReduced API latency 42% beats worked on performance. Quantified bullets scored 11 points higher on recruiter review.
11 Use standard section headings: Experience, Education, Skills
+8 ptsCreative headings (Where I made impact) are not recognized as section anchors by Workday or Taleo. Standard headings add 8.3 points.
12 Keep the resume to one or two pages at 10.5 to 11.5 pt body
+5 ptsFonts below 10 pt break line detection. Three-page resumes are rarely read past page one.
The before and after bullet lab
A rewrite that applies rules 5 through 11 is worth 40 to 50 score points on its own. Four examples drawn from the recovery dataset.

Exact acronym pairing plus quantified impact.
The acronym plus spelled-out rule, explained
Writing "Search Engine Optimization (SEO)" once satisfies both a legacy Boolean parser like Taleo (which indexes "Search Engine Optimization" and "SEO" as two separate tokens) and a modern semantic ranker like Greenhouse (which recognizes "SEO" as the dominant term and expands synonyms around it). The data: the parenthetical pairing raised Taleo match rates by 19.4%, iCIMS by 11.6%, and Workday by 9.3% in our Fortune 500 audit.
Apply it once on first mention. Use the shorter form in the rest of the resume. Over-pairing dilutes the signal and makes the resume read like a glossary.

Frequently asked questions
How do I pass an ATS scan in 2026 step by step?
Export your resume as a single-column PDF or DOCX, keep contact info outside headers and footers, use standard section headings, cover 72% to 84% of the posting's hard skills, pair every acronym with its spelled-out form, and run the file through an ATS compliance checker before you submit.
What is the best ATS compliance checker in 2026?
ATS Resume Checker offers the best balance of accuracy, speed, and price. Free users get 3 scans per day with no signup, Pro is $9 per month flat for unlimited scans and AI bullet rewrites. Compare to Jobscan ($49.95/mo), Teal ($29/mo), and KudosWall (credit tiers) on the comparisons hub.
How many keywords should my resume have to pass the ATS?
Target 72% to 84% match on hard skills, with each critical skill appearing 1 to 3 times total. Above 92% match density you look stuffed, which Greenhouse and Lever penalize. Breadth of unique skills beats repetition at roughly a 7 to 1 ratio in the 2026 data.
Do I need to customize my resume for every single job?
