A third way to optimize your resume is to format it for readability, both for humans and machines. Readability refers to how easy it is to scan and comprehend your resume, and it depends on factors like layout, design, font, color, and spacing. To format your resume for readability, you should use a simple and consistent layout that highlights the most important information, such as your name, contact details, headline, summary, skills, and achievements. You should also use a professional and legible font, such as Arial, Calibri, or Times New Roman, and avoid using fancy or creative fonts, graphics, or images, as these can confuse the ATS and distract the human reader. You should also use white space, bullet points, headings, and subheadings to break up your text and make it easier to scan. Finally, you should save your resume as a PDF or a Word document, as these are the most compatible formats for the ATS and the human reader.
