Ultimately, employer branding efforts aim to communicate the expected utility that a potential employee should anticipate from joining a company, and so build employee based brand equity. This can also be described as employer attractiveness (Berthon, Ewing & Hah 2005).If potential employees have to commit high levels of resources in order to gain insights into a company, they may associate higher risk with joining the company and perceive the company as a less attractive prospective employer. If the information gained via signals is promising,perceived risk is reduced and the anticipated quality of a job enhanced. Consequently,potential employees will perceive the employer as more attractive (Aaker 1991).
