Competition in the job market is fierce, and if you hope to land a new position, you must stand out from the crowd -- but for the right reasons. You want to provide hiring managers with a positive impression, so here are a few messages you should get across right from the start.

1. "I'm professional."
Potential hires who take the application process seriously will be treated similarly by prospective employers. This means, for example, proofreading your application materials for grammatical or spelling errors. It never hurts to have someone else review your cover letter and résumé as well, in case you overlook something. Also, be careful with the type of language you use. Remember that your application materials are business documents, so avoid slang or casual speech, such as the kind you might use when text messaging with your friends.

2. "I'm a go-getter."
Because hiring managers are being inundated with résumés, your application materials may get only a cursory glance. That's why you need to take some initiative. For instance, when you initially contact the employer, instead of ending your cover letter or e-mail with a standard statement like, "I look forward to hearing from you," be proactive. Try: "I will contact you next Thursday at 3 p.m. to discuss the opportunity and my fit for the position in greater detail."

Also, unless you're specifically asked not to, follow up with an employer if you haven't heard back after sending in your résumé. In fact, 82 percent of executives polled by Robert Half International said job seekers should contact hiring managers within two weeks of submitting application materials. By doing so, you can reassert your interest in the position and remain at the top of the hiring manager's mind.

3. "I'm an expert."
Employers want to hire people who can hit the ground running. That's why you need to demonstrate your expertise from the beginning. Three great methods for doing so are enhancing your online reputation, joining a professional association and earning a certification.

Options for increasing your exposure include starting a professional blog or Web site, submitting articles to an industry publication or even simply contributing to message boards. For instance, blogging about the industry that you want to work in and including the blog's link on your résumé give prospective employers an easy way to see that you are well-informed.

By joining industry groups and trade associations, you can remain up-to-date with recent trends through interaction with others in the field. Use your résumé to highlight your membership in a professional group and show hiring managers your interest in furthering your industry knowledge.

Finally, consider earning a relevant industry certification. Many employers value candidates who have these credentials because they demonstrate a desire for continual professional development.

4. "I can save your company money."
In today's economy, companies are looking for ways to reduce costs. If you've implemented successful cost-cutting measures for previous employers, describe how you did so in your résumé or cover letter. For example, when applying for a role as an administrative assistant, you might note that in your last position, you helped renegotiate your company's contract with an office supplies vendor, reducing spending in this area by 10 percent. Hiring managers will take notice of these types of accomplishments.

5. "I can fill your need."
To show that you are an exact fit for an open role, make sure your application materials are targeted to each position and company. Use phrases from the job description within your résumé and cover letter, so long as they accurately describe your experience. Many employers use software programs that scan application materials for relevant keywords, so even if you are qualified but don't use the employer's terminology, your résumé may never be seen.

Sending the right messages to a prospective employer may not guarantee that you are offered the job, but it will increase your chances of being called for an interview. Then, you can make your case in person.
