Keywords in a CV (also commonly called a resume) or cover letter are words or phrases that highlight industry-specific skills and experience those employers are looking for.
Usually, keywords are related to specific hard and soft skills an employer is looking for. You can generally find important keywords by looking through the job advertisement and noting any words listed in the “desired qualifications” and “responsibilities” sections.
Sprinkling keywords and phrases throughout your CV and cover letter will make you seem like the ideal candidate and help you get through an applicant tracking system (ATS).
