A resume is a document that explains your skills and background to potential employers. It helps highlight the things you’ve done in an engaging and informative way to help better match you to a job. A resume is different from a curriculum vitae (or CV) in that resumes are usually about one page long, while CVs can run from two to three pages, or even longer.

Depending on the industry you work in and the nature of the job you are applying for, you can include different sections on your resume. Usually, a resume should start with a heading listing your name and contact info. It can be followed by sections such as your career experience, education and relevant skills, licenses or awards.

Resume builders are online services that create a personalized resume for you. They will ask you to fill in questions such as the places you have worked, what schools you have gone to or what your career objective is. Then, the websites will combine the information into a document you can submit to employers. Some services will include pre-written descriptions or even professional resume writers.

Writing a good resume is hard—it needs to be both visually striking as well as interesting to read. Moreover, many employers automatically scan resumes for the right “keywords” which they will use to decide which job applicants are worth interviewing. Keeping track of all of this, especially as someone new to the job market, can be difficult. Resume builders help you create a document that is perfectly tailored to your job search.

Most resume builders are available for a small fee, though they usually offer a trial period for users to explore the different options and features available. Other resume builders may utilize a “freemium” model in which the core service is free, but certain features—such as support from a professional resume writer—can be acquired for a fee.
