What is meant by employee profiling in sourcing?

What will be an ideal response?

Just as marketers use customer behavior profiles to better position products in the market, talent sourcers use "employee profiles" to identify effective ways of reaching desirable talent. Employee profiling identifies what desirable talent and successful current employees in targeted jobs like to do and how you might reach them if you were to try to recruit them now. This information is then used to source similar people. Choosing recruiting sources that would reach current high performing employees increases the chances that the recruiting message will reach comparably skilled and talented people. Identifying the sources for which top performers differ from poorer performers can help prioritize recruiting sources for the position. Then evaluate which sources attract applicants and particularly high quality new hires to further refine the sourcing strategy.
