If you are applying for various jobs but which are all in the same industry, you could write a profile that applies to all jobs in that particular industry. However it is preferable if you write your personal profile for each individual position.

If the profile is tailor-made to the job vacancy then the employer will read the rest of the CV whilst bearing in mind that you are a possible match. A personal profile on your CV is a teaser or hook so the employer will investigate you more by reading the rest of your CV.

Keywords are a powerful tool in your CV and should be used! Use keywords to summarize your experience. Keywords will also help ensure that your CV comes up when employers search in their CV databases.
