How do I increase my ATS score I have tried all online tips and still score between 30 40 on online resume checkers

Do this focused checklist—one targeted pass per job listing will beat generic “tips.”

• Pick a job posting and copy its exact job title and 8–12 high-impact keywords/phrases (skills, tools, certifications).
• Mirror those keywords naturally: put the exact job title at top, and sprinkle keywords in your summary, each relevant bullet under Experience, and a dedicated Skills line.
• Use plain formatting: single-column, standard headings (Summary, Experience, Education, Skills), regular bullets, no tables/text boxes/graphics, contact info in body (not header/footer).
• Include both acronym and full form (e.g., “SQL” and “Structured Query Language”).
• Quantify results in each experience bullet (numbers, %s, timeframes).
• Save and submit as .docx (or the format requested). To check what ATS sees, copy your resume into a plain-text editor—that’s the parsed order.
• Make one tailored resume per job; focus on relevance over length.

If you want, paste the job title and one job posting you’re applying to and I’ll give the exact keywords and a revised 2–3 bullet example for your resume. What job title/industry are you targeting?
