Keywords are certain words that you’ll find in the job description during your job search that tell you the specific skills and experiences an employer is looking for. These words will be picked up by applicant tracking systems (ATS) employers often use to scan CVs and make sure you’re qualified for a specific job.
Action words, on the other hand, are verbs that showcase how you do certain things in your job. They’re both words you’ll use all throughout your CV, but one of them helps with ATS and the other helps when it actually gets to a hiring manager.
