Applicant Tracking Systems (ATS) are software that scan resumes for keywords and structure. They look for role names, skills, dates, and contact info. If your resume hides information in odd formats, the ATS can skip it.

For a Private Investigator, ATS optimization matters because many firms screen resumes automatically. ATS matches words like "surveillance," "skip tracing," "background checks," "case reports," "evidence handling," "CCTV," "GPS tracking," "chain of custody," "TLOxp," and "report writing." Include those exact terms when they match your experience.

Best practices:

• Use clear section headers: "Work Experience," "Education," "Skills," "Certifications."
• Weave job-specific keywords naturally in bullets and summaries.
• Avoid tables, columns, text boxes, headers, footers, images, and graphs.
• Use standard fonts like Arial, Calibri, or Times New Roman.
• Save as .docx or simple PDF and avoid fancy templates.

Avoid creative headers like "What I Did" or "My Toolkit." Don’t replace exact keywords with clever synonyms. Don’t bury dates or contact details in headers or footers. Missing keywords for tools like "LexisNexis," "CLEAR," or "TLOxp" can stop you from passing filters.

Keep bullets action-focused and measurable. Start bullets with verbs like "conducted," "managed," "documented," and "served." Use short lines and consistent date formats. This helps both ATS and the human reader.

Pick a clean, single-column template focused on facts and timelines. Use reverse-chronological layout so your recent field work and investigations appear first. That layout reads well and parses easily for applicant tracking systems.

Keep length tight. One page fits most private investigator roles with under ten years' experience. Use two pages only if you have long case histories, legal testimony, or many certifications to show.

Choose readable fonts like Calibri, Arial, Georgia, or Garamond. Use 10–12pt for body text and 14–16pt for section headers. Keep margins and line spacing consistent so each section breathes.

Use clear headings: Contact, Summary, Investigations, Technical Skills, Licenses, Education, References. Bullet recent cases or tasks with short outcomes and metrics. Use action verbs and quantify results when you can.

Avoid flashy designs, heavy columns, or background graphics. Those elements confuse ATS and distract human readers. Stick to simple bolding and spacing to highlight items.

Watch common mistakes. Don’t use images, odd fonts, or multiple columns that split dates. Don’t cram content with tiny text or long paragraphs. Don’t forget clear dates and consistent formatting for locations and employers.

Proofread for clarity. Keep language direct and factual. That helps hiring managers and investigators quickly evaluate your experience.

Tailoring a cover letter helps you connect your background to the Private Investigator role. It shows why you fit the job and why you want to work at that company.

Header: Include your contact details and the company's contact if you have it. Add the date so the reader knows the timing.

Opening paragraph: State the Private Investigator position you want. Share real enthusiasm for the role and the firm. Briefly name your strongest relevant qualification or where you found the posting.

Body paragraphs: Use 1–3 short paragraphs to link your experience to the job.

• Mention key investigations, case types, or methods you used.
• Name specific skills like surveillance, interviewing, or report writing.
• Show soft skills such as problem solving, discretion, and teamwork.

Give measurable results when you can. For example, state how many cases you closed, how much evidence you found, or time saved. Use words from the job posting to match what the employer wants.

Closing paragraph: Restate strong interest in the Private Investigator role and the company. Say you can add value and invite next steps. Ask for an interview and thank the reader.

Tone and tailoring: Keep your tone professional, confident, and warm. Write like you talk to a colleague. Use short sentences. Edit each letter to match the employer. Avoid generic templates and stock phrases.

Practical tips: Proofread for clarity, check facts, and keep the letter to one page. Use active verbs and keep every sentence focused on what you achieved and how you will help the team.
