You may have all the experience and achievements in the world--but if you can't effectively communicate your successes, you will have a hard time convincing others you deserve a job or position.

It is obvious that any résumé or material you submit with a job application should be read and reviewed by you enough times to spot and take out all errors or mistakes. But knowing what to take out from a résumé can be easy. What's harder is knowing what kinds of information or descriptions you should put in.

Google sometimes fields more than 50,000 applicants each week, so if you're in need of résumé advice, it's a good idea to listen to what Google's recruiters have to say. When it comes to résumés, they've definitely seen the good and the bad. Here are 5 simple things these career experts say your résumé absolutely needs.

1. Focus on impact.

An accomplishment is impressive, but what really makes potential employers pay attention is what kind of impact that accomplishment has left with your organization and customers. Has your work resulted in an improvement in sales? Can you confidently say an initiative you led increased client acquisition?

2. Data and examples.

Not only should you highlight your accomplishments and their impact, but you need specific data and examples with these achievements as well. Use numbers--quantifiable examples of success--to let hiring managers know you're the one for the job.

3. A clean and consistent format.

Your résumé should be perfectly legible and look pristine. Use black ink on white paper with half-inch margins, and make sure all columns are aligned. Keep fonts, sizes, and spacing consistent. And keep your résumé tight. Says Laszlo Bock, former senior vice president of people operations at Google, "Once you're in the room, the résumé doesn't matter much. So cut back your résumé. It's too long." Craft a concise and focused résumé that prioritizes the most important information. Save the life story for later.

4. Relevance to the job description.

If you're desperately seeking employment, you might think it's a good idea to send the same résumé out to 50 different employers. But if you want to actually advance to an interview round, you need to read a company's individual job description and tailor your résumé specifically to that job's duties and requirements.

5. Be fearless.

As you describe your previous job experience, let recruiters know what kind of selective process you endured in order to be chosen for a role or project. Don't be afraid to brag-- your résumé won't be the best it can be if you choose to be shy.
