In order to get found, your resume needs to contain keywords that directly target the jobs you are interested in.
The keywords in your resume should reference specific job requirements, including your skills, software and technology competencies, relevant credentials, and previous employers.
Using resume keywords increases the chances of your resume being compatible with a job that's open and your resume showing up in the hiring manager's search results.
Cover Letter Keywords
Similarly, you can include keywords in your cover letter. This way, if your cover letter is screened, you will have a better chance of getting selected for an interview as a qualified candidate.
How to Find Keywords
To find keywords to use, take a look at some actual job postings. Search for job listings that match your background and experience. Then look at the keywords including in the job postings and incorporate them into your resume.
Use a job search engine so you can find jobs from a variety of job sites. Then compare and contrast and pick the keywords from the job postings that are the best fit for your skills and qualifications.
Be specific. The more focused and specific you are, the better chance you'll have at being a good match.
