Match the need they have—Do your homework and review the company's job posting online or in the newspaper. Each position will usually have a brief description about the company and the position available. Take note of keywords in these ads, and match them to the bullet points in your resume. Chances are that some of these words might already be in your cover letter, but if you've missed some, make sure to add them in your resume. Writing your resume this way will make it a better match for the eyes of your potential employer and will greatly increase your chances of getting that job!
