The trick to writing a good cover letter is to tailor it to each individual job description. Your goal is to prove that your qualifications match the employer's requirements for the position. Try to use key phrases from the job description in your cover letter. The ideal cover letter is around half a page long (no longer than one page) and written in professional business letter format.
