About this guide library
These guides teach one skill per article. The writing cluster covers the document itself — structure and formats, bullet points, action verbs and quantified achievements. The ATS cluster explains how screening software parses, ranks and filters applications, and the formatting rules that keep every field readable. The examples library holds copy-ready models for summaries, objectives, headlines, skills, projects and certifications, and the applications cluster deals with what travels with the resume: cover letters and references.
They are written for people doing the work themselves — first-time job seekers assembling their first CV, experienced professionals tightening a two-page resume, and career changers translating one field into another. Every guide answers a specific, searchable problem: why a resume gets filtered before a human reads it, how to tailor it to a job description in about fifteen minutes, or which keywords a recruiter's search is likely to match.
Start with the reading path below if you are building from zero, pick a topic if you have one problem to fix, or search the library for the exact section you are stuck on. Each article ends by pointing at the free tools this site is built around, so you can apply the advice the moment you finish reading.
Pick the problem you are working on. Each topic lists the guide or free tool most readers start with — no sign-up, no email wall.

Short answers to the questions these guides are most often opened for — each with the guide that goes deeper.
Use a clear reading order, familiar section headings and selectable text where possible, and follow the employer's file instructions. Accurate wording from the job posting can help readers recognize relevant experience. Copying the exported text into a plain-text editor can reveal layout issues, but it cannot predict how a particular ATS will process an application.
Read the seven-step ATS resume guideStart with contact details, relevant experience, education and skills. Depending on your background and the role, add a concise summary, projects, certifications or other useful evidence. Follow the employer's instructions and local conventions for personal details, references and document format.
See the full section-by-section buildThere is no universal page-count rule. Include enough relevant detail to support your application and remove repetition or unrelated material. Follow any length guidance in the posting; academic CVs may follow different conventions from industry resumes.
Compare formats and length rulesKeep a master version, then review it against the role. Where relevant, adjust the summary, skills and examples to reflect requirements you genuinely meet. The time involved depends on the application, and no particular edits guarantee a response.
Match your resume to a job descriptionStart with the skills, tools, qualifications and role terms in the posting that you can honestly support. Using the same names where accurate can help a reader connect your experience to the requirements, but search and matching behavior vary by employer and system. Work the terms naturally into relevant sections rather than repeating them mechanically.
